New LED lightbulbs shine light in all directions

GE is going to be releasing a new LED lightbulb early next year that shines light in all directions, like a normal bulb, instead of one direction like they do now. The bulb will use 9 watts and shine as much light as a 40-watt incandescent. It will also last for 17 years. The drawback is the cost, which will be $40-$50, but it does provide an efficient lighting option for those who don't like the light from CFLs. No word about the blades on the side, however.

Small Lightbulb question

Hi there I feel ashamed to ask this question as it is probably so simple I have some small MES bulbs.. they have 6/8V 0.15A stamped on them I want to run them off a battery... on a parallel circuit... would 4x 1.5V batteries (6V total eg 4 AA batteries) in a battery holder work for them?? and would I need a resistor to stop them blowing?? (I am trying to run 3 bulbs in parallel for an instructable... best reply gets put in the credits at the end, but you don't get royalties lol!) any help welcome Will

LEDs as a replacement?

I've been thinking, which, for me is strange. What's stranger, i've been thinking about saving the planet. I don't believe that global warming is solely the fault of man and his machines, nor do i believe that we're all going to fry in a ten-thousand year summer, but that's not the point of this forum, and i'd appreciate no comments labelling me as a communist, or a planet-hater. What i had in mind is a new system of lighting. Say i took some LEDs (lets say 16) and connected them in paralell, and attatched them to the appropriate power source, would they be more or less efficient than a tungsten filament lamp? As for aesthetic considerations, to simulate natural sunlight during winter months, one could add blue or yellow LEDs to tune the shade of the light. Would this idea be more efficient than the lights we have? (i avoided mentioning those energy-efficient lights because they're not really that efficient, and give crap light.)

Inverter to Flaslight bulb?

I am building a basic night light ordeal, and I used a photoresistor to detect the change in light. Of course, the photoresistor will, by default, only have a high output when there is light, so I used an inverter (Not Gate). My inverter is made up of a transistor , a 1.5k resistor, a 10k resistor, and leads off to a LED. The photoresistor would go off to the Base of the transistor, so it can invert the output. Originally, I had this hooked up to a 4.5 volt input (the photoresistor has 4.5 volts going to it, and the transistor had 4.5 volts going into it), but I wanted to brighten it up, so I upped the voltage to 7.5 volts so I could add a 6.3V Incandescent Flashlight Bulb (http://www.radioshack.com/product/index.jsp?productId=2102809). When I hook this up to a regular 6 volt battery pack, I easily turn the light on. When I connect it to the inverter, however, I don't get anything going on. I've upped the input voltages to 9 Volts, but still, no dice. Everything works fine until I change the LEDs to the bulb. So far, I've changed the resistor values in both directions (I've decreased them down to 10 Ohms, and increased them to a max of 1M Ohms). The only way I can possibly get this to work is by removing the Resistor going to the Collector, but then it is constantly on. The output of the photoresistor no longer matters. The output of the inverter is constantly high. Any ideas? All help is appreciated.

Light project for a new room.

Hi everyone.My parents recently bought a new house and it turns out one of the rooms has no lamp connections whatsoever(Everything is ok, there just isn't any wires for the light bulbs).Because of multiple reasons we can't call an expert over so the job falls on me.I have experience in electronics but I'm afraid to try adding a route like the one that should be there so I'm searching for something safer :).All ideas are welcome :)

Microwave transformer ballast

I recently got a working microwave transformer for free, it has unknown wattage, though. What's the best way to ballast it? Some people use lightbulbs, I'd rather not use lightbulbs cause that's almost as dangerous as the lightbulb it's self (I'm comfortable with the transformer, I'm not comfortable with a 500 watt lightbulb, ironic?) No saftey speeches, please, lol.

diy 110v AC screw-in LED lightbulb?

I'm sort of an electronics newbie, but I'm wondering if anyone knows of any designs to make a 110v AC LED screw-in bulb? It seems all you would need is a full wave bridge rectifier, a resistor(?) to lower the voltage, some LEDs, and some variation on a screw-in base to make a home-made LED bulb. Am I wrong, or shouldn't that be relatively simple to build? Any thoughts? Thanks, Matt

creating a light that works on a blood pressure sensor/heat sensor

Hey I'm new here and have recently been thinking that I want to create a light that would work (i.e. turn on) when specific readings from the body are met. So far I have when a low and stable blood pressure reading is met (indicating happiness) or when a specific temperature reading is met (also can indicate happiness) I think I'm more inclined to want to build it with the blood pressure reading as the heat one could just turn on if you are hot. However I have HONESTLY no expeirience in building electronics but am really keen to learn! Could anyone point me in the right direction to where I should be looking please and what some of the steps I am going to need to take are please?  In my mind it would work when a blood pressure reading is taken and the monitor shows a reading within the healthy and happy range. However I literally have no clue how to tell a lamp to turn on when this is achieved  please please help me out!  thank you so much in advance Holly :^)

Led Lightbulb for r7s socket or how to repurpose from rs7 to gu10 or other sockets

I have some nice wall lights but mounting R7S bulbs. These are halogen and of course use a lot of electricity. I have looked everywhere for a compatible LED lightbulb but the problem with all the ones available is that they are designed to fit floodlights, ie. they take too much space and cannot be fit if your socket is a small linear r7s. Attached example of the led bulb shows that behind the connectors the casing takes too much space and this is what is stopping me from using these lightbulbs. Also u can see my lamp and how tight the space is behind the halogen bulb So questions 1 - do you know where i can find such a lightbulb with no space or very little space behind connectors ? or 2 - any instructions on how i can repurpuse the current lamps by replacing the current R7S socket with something else?  I dont know much about electrics so i wanted to get a understanding with a step by step process so that i dont blow myself up. pls notice this forum images are not getting saves so here is a link to a album to the wall lamp images

L.E.D. wifi controlled lighting

There are currently 2 different systems in production, LIFX (kickstarter) http://www.gamers-pad.co.uk/2012/10/lifx-led-lighbulb-lighbulb-re-invented/ And Philips Hue - released next year (in the UK) http://www.gamers-pad.co.uk/2012/11/philips-hue-wi-fi-lightbulb/ Both systems promise amazing leaps forward in control and ambience, but both are expensive. I think they are going to be a way forward eventually and will re-invent the lightbulb. But not being technically proficient at electronics, has anyone made an instructable or is anyone in the process of making one? I can generally follow instructions well enough, but for the most part this is beyond me to make and design myself.

Secret playroom behind wardrobe

This wardrobe is actually a secret entrance to a playroom. The owner of the house had the wardrobe and figured he might as well add a touch of magic to the house for a pretty amazing result. This reminds me of an apartment I once visited in San Franciso. There were two refrigerators in the kitchen. One was normal and the other was a secret door. Walking through it led you to a dark hallway that ended in a small room with a single chair in the middle and a single lightbulb hanging down over it. Creepy as hell.

Foam Board/Cardboard Shoes

Hey, I was walking past my little sister watching PBS Kids and on one of the shows this girl was trying to make her own shoes. Out of cardboard. Lightbulb. The only reason that they didn't work is because they got waterlogged. I am thinking that with good enough sealing and strong enough glue, useable shoes made from cardboard are a possibility!The only problem is that I don't have foamboard or time to spare or a working camera at the moment. If anyone could carry this idea further than me, have at it!

So in order to make a black light i (the stupid half of me) would think to dip a lightbulb in black paint. i (the smart half of me) would assume there is more to it than that here is some random 2 facts about the blacklight (wood's light) it is not black its a deep-bluish-purple what a blacklight emits is: lamp emitting electromagnetic radiation my question is how could i make one and would it be cheaper to make it or buy it...

Light Socket Extension help

Can you help me find a safe way to build a cheaper version of this: http://reviews.lowes.com/0534/3125483/reviews.htm?   Here's my situation: I want to convert double-lamped can lights into adjustable spotlights without making any permanent changes other than unscrewing a lightbulb and replacing it with something else.  It needs to be able to go back to a lightbulb very easily.  The cans stick out from the wall and each socket is oriented vertically, so one points up and one points down, effectively washing the wall up and down with light.  The wall of 8 or so are wired so the tops are all on one circuit and the bottoms are all on another circuit. The item from Lowe's works OK, but is $17 and more flexible than I need.  Here's what I started to put together:   At the top is a 100W Par38 spot light, screwed into a single outdoor metal lampholder.  That is attached to a 1/2" pipe (PVC or metal), about 12" long.  Now, at the bottom of the pipe, it needs to screw in to the socket to get power.  I either need to get an E27 lamp base onto that pipe, or use a two-blade outlet adapter that screws in, and get a two-blade plug that is rigidly fixed to the pipe.   Is there anyway to do this that the NEC would smile at?  Absent of that, a way that is still safe and secure, and safely removeable without changing the existing light socket arrangement?

Using Tungsten to Ignite Gas?

Alright, so Tungsten (which you may or may not know, is my favorite element) is combustible when current passes through it while it is exposed to oxygen. Could I place a bit of tungsten I scavenged from a lightbulb in a small pool of gas (or alcohol) while running 9 volts through, and get a reaction? Would having the whole bit of tungsten under the gas work, or would I need a piece above the gas also? I'm not looking to blow things up, just trying to do a bit more "dangerous experiments" before school starts. Thanks all!

Tesla illusion ideas / wireless light bulb help

So I was considering going as Nickola Tesla for Halloween and showcasing his ideas as sort of party tricks...like a Tesla turbine blade and whatnot. But seeing as he is primarily known for electricity work, I thought it would be cool if I could somehow come up with a way to make a lightbulb glow while holding it. I tossed around the idea of running a powersource to a conductive glove to power it and also of making a self contained powered bulb but not sure. Any ideas on how to make some sort of electrical phenomenon illusion? Thanks.

CFL

Who else uses CFL ( Compact fluorecent Lightbulb) I my self replaced all my rooms light with them, so 4 bulbs in total. They sell them at Sams club, 8 CFL units that replace 60 watt bulbs for about $10. Instead of using 60 watts they only use 13, also they do not get as hot making your room cooler in the wee hours of the morning. Im not sure if they sell them for the smaller bulbs like the skinny ones ceiling fan, because thats the kind of bulbs we have on our wall. I decided not to use that light for now. Most of all the light bulbs in our house are fluorecent, except the bathrooms, a few lights we use rarely and the 3 different intensity bulbs. Who else uses CFL and if you don't, do you want to switch?

Eco-conscious: Compact Fluorescents

My friend Rawhide did a decent bit of research into the best type of compact fluorescent lightbulb, so I'm sharing is findings here. Do you have anything to add?Rawhide on compact fluorescents:In all my web searching I couldn't find a truly exhaustive comparison on lightbulb stats. Even Energyfederation.org, which was the most comprehensive, didn't list the CRI for all of its bulbs. What I did realize was that the "bright white" bulbs I bought from Home Depot were of the wrong color temperature to mix with incandescents and that is why they looked so cold. I also found a couple of people who really liked N:Vision, the Home Depot brand.So I decided to give Home Depot another shot and exchanged the bright whites for soft whites. Curiously, when I went back the CF bulbs had a big display that wasn't there the week before with the bulbs I wanted in $9 4-packs, which was much cheaper than the individual bulbs.I replaced all the bulbs in our living room and dining room and I (and the nameless other) find the light quality to be quite good---it wasn't possible to distinguish the CF from the incandecent bulbs once they warmed up. If you look at the light in the room as a whole, there is the slightest bit of 'vibration', but it's really not noticable unless you're looking for it.Net savings: 600W->140W to light the two rooms. Awesome.Finally, as a coda to my quest for compact flourescents, I learned that Massachusetts is offering a $2 rebate per package for Energy Star lights and that Home Depot also sells 6-packs for $10. So, you can get 60w replacement bulbs for $1.30 rather than $4 or $5 you sometimes see. http://www.myenergystar.com/rebates.aspx Retailers need to supply the coupons, which are instant rebates at the register. There are also bigger rebates, like $75 off a dryer and $20 off a torchiere light fixture.

miracle in my dorm room?

Ok i'm no genius, so this might be a stupid question i goto to boarding school, and i have one of those plasma globes with the electricity inside, and when you touch it the electricity move to your fingers anyway, my roomate has this lamp, and i swear to god how it works is beyond me the lightbulb sits in the bottom of a tall metal box frame , the sides of which are covered with lampshade paper and the top of which is open it has three intensity settings, and to switch it through the three you lightly rap on the metal of the frame with your finger BUT: it doesnt work if you shake it, and if you tap it with plastic, metal, or a magnet nothing happens in addition to all that, if i sit the plasma globe near it and flick it on or touch it, the jesus lamp switches up to the next intensity (after the third it turns off) i think it might be a midget in my desk drawer, but if anyone knows better PLEASE enlighten me as to whats going on...

I won!

I posted this topic before, but I don't think anybody saw it (instructables glitch?)From wendsday to saterday i went to a resort named 7 springs in champion, Pennsylvania. I was there for a national competition called technology student association (aka TSA). This competition was states, for I already went to regionals.I won 1st place in Electrical Applications, which is basically your knowledge of electronics (you take a test) and you have to create a circuit on a bread board, along with creating a schematic. I tell you, this was almost a joke. Questions on the test are like --| C---- what is that a symbol of? And what does IC stand for?The breadboard challenge was even easier. They gave you a breadboard, a 9 volt battery, a lightbulb, and some wires. The challenge was to make a circuit (and schematic) that light up the lightbulb whenever you touch the probes to the right spots. Like you know those question and answer things at science fairs where if you line up the right question with the right answer? That's basically it.I also won 1st place along with a couple of my friends for a medical challenge where we gave a presentation on alzheimer's disease. Not much to explainMe and my friends also won 3rd in another thing, I can't remember (I get my trophy on wensday because they didn't have enough trophies for the whol group). I think it was in agriculture and biotech where we talked about biofuels.Me and my friend got 6th in a challenge where they give you a random technology topic and they give you 10 minutes to prepare (no computers) and then you have to give a speach.Me and my friends got 10th in a thing called tech bowl where they give your random questions and you are in direct competition wire people nexy to you (you have a buzzer).Me and my friends got 9th place in a challenge where we talked about the enviroment (specificaly ozone depletion);)does anybody know where this came from, I'm pretty sure I saw it at TSA (I just remember a yellow wrapped transformer at an angle in a box with a phone and it's all in a box)http://blog.makezine.com/archive/2008/04/send_an_sms_to_save_your.html#comments.

Need a small 12v heat source for simulated HVAC project

Okay, so for our year end micro controller project we need to control a temperature inside two 2L pop bottles connnected together. We have a computer fan mounted at the end of the "heating bottle" which needs a heat source in it. The fan will blow the hot air from "heating bottle" into "temperature bottle" which contains an analog temperature sensor. We have to control a set reference temperature point in "temperature bottle" using a PIC16f690 microcontroller by manipulating the fan speed and heat ON/OFF. Problem: I need a decent heating source inside "heating bottle" . Ive been using 12v automotive lightbulbs which work great for a minute or two but then die out. My crappy power supply can only pump out 1 amp, could this be why? Any suggestions on what to use as a heat source? I was thinking some 5w resistors but classmates have said our power supplys cant handle them either. Thanks in advance!

Heat powered cooler?

It's rather warm around here. And by "rather warm," I mean it's 105 in the shade, and it's 89 in the house with the swamp at full blast. Does anyone have an idea for powering a cooler with pure heat? Perhaps similar to those lightbulb-looking devices that have an inner bit that spins around when placed in direct sunlight, except that is running a little generator that is then running a computer fan, like the ice box air conditioner spotted on this site. The main thing is I'd like the device to actually be powered by heat. Just for the heck of it. Even if it's just heat mechanically powering something to power a fan that I could have just plugged into the wall. So no solar cells making electricity. I can make parabolic reflectors easily if needed, so don't be afraid to use them. What's the best way you can think of to cool off using heat? "Best" can include inefficient but really awesome, like a fresnel lens pointed at a boiler that is providing steam to run a gigantic fan. I'll go get my goggles, ray gun, and keys to the airship.

HELP! device to hang pots and pans that lowers with electric???

I have very limited space in my kitchen and leave my pots and pans on the stove when i'm not using them but they get in the way.  I remember, in the old days, they had ways to hang them from the ceiling and could raise and lower them with a rope.  Since I have limited space, I was thinking about a copper pipe mounted on a system where you could push a button to raise and lower the pipe along some sort of track mounted to the wall that holds the pipe out 12-18 inches away from the wall.  (Almost like a wire rack shelf idea where the shelf would electronically move up and down.)  I could then hang S hooks from the bar and hand the pots from the hooks and raise them up along the wall, out of the way until I need them and lower them without a pulley or getting a chair.  I can usually manage to change a lightbulb all by myself but I am lost on this idea.  Any inexpensive suggestions???

Maximum/minimum ampere input in a circuit, help needed.

To start of my question im going to say i don't know a lot of electronics and that I am norwegian( so please excuse typos in english) :) I have not done many major projects inside the field of electronics other than making a lightbulb light up. using a battery and to wires.. But I am very interseted in electonics ad think it is very exiting to read about.  As my first "real" project i decided to make a "lie detector", altough it is mostly just a circuit that measures the resistance in your skin and makes a beeping sound after how much resistance your skin has( Dry skin = low resistance vs wet/sweaty skin = much resistance). AND I DID IT! i made it work, and i was so proud! Then I realized that it was actually kinda lame and the beebing noise was wery annoying. So I decided to make a display that displayed a value after how much resistance your skin held. I managed to make a seven segment display from scratch. But now I am stuck... You see the circuit gives an output of amps so it will output more amps on wet skin than on dry skin. But I have to "program"  the circuit to make the numbers on my display change. I want preferably to be able to do this without any IC's. So my question is there possible to make a circuit that will allow current to pass through one circuit, but if the current is high enough it will take another way? I tried to use diffrent resistors, but I didnt take into count that electricity only takes the road of least resistance no matter..

Small generators.

Most everyone here knows (I assume) how the generators work in RC cars and there's an instructable that shows it can be used to output electricity. Elementary science at it's best. If any of you have took them apart you'd notice it draws eletricity from touching the center metal pole. Two little brush/copper/zinic contacts. Basically I've been trying to think of ways to extract eletricity without having a need for them. They cause friction. Uh-oh, a few lightbulbs lit up in peoples minds by now and they're going "oh no not another person trying to beat the laws of thermodynamics and acheive perpetual motion" Yep. As we all know eletricity CAN jump if it's powerful enough and arc, but this doesn't make it too safe either. However it's a small scale model to start out and can be contained so the arc won't be a problem. My other problem is the calculations. They need to be precise. To get it working I need a low rpm generator that will generate high output. For this it requires torque which kinda kicks me, it will also need to use (I assume) rare earth magnets. So basically lets stick with my latter problem since it's more down to earth. I need a fairly small generator if possible (It can be larger if no other solutions are present) At least the size of a walnut I don't plan to make anything immense in size as I lack the funding. As pointed, small is key. Not to be redundant but to paint a clearer picture. It will also need to generate decent voltage at a low rpm speed. I cannot emphasis this enough because it's one of the key parts to make my idea function. Hum... Yeah that about covers it. So if any tech wiz's are out there that know of such thing I'd apperecaite it if you'd part the knowledge to me :P I'm also very aware that perpetual motion is eh, impossible... by current standards. The intention of this project is to deepen my knowledge and figure out why things won't work, figure out solutions and on so forth. A learning project for now and perhaps one day it might become something far more awesome.

Homeowners go greener with do-it-yourself jobs

Michael Davis and his 60 Watt DIY Solar panel were mentioned in SFGate's Homeowners go greener with do-it-yourself jobs.Like a lot of Bay Area homeowners, Alissa Hauser and husband Steve Brown have already done the small things to save on utility bills and pursue a green life: lower the thermostat, install energy-efficient lightbulbs, use old T-shirts for rags instead of paper towels.But earlier this month, the East Bay couple took a longer stride into the do-it-yourself green home improvement era by spending a Saturday afternoon routing gray water pipes from their laundry machine to their garden. Now, each time they run a load of dirty clothes, the excess H{-2}O runs through a filtering system that waters their apple, plum and lemon trees. "In many ways, environmentalism has become an expensive, consumer-driven effort," Hauser, a director at a nonprofit, said. "But this kind of project proves environmentalism can be a money-saving lifestyle, too."...Michael Davis, a Florida inventor who owns property in the Arizona desert, became a minor DIY Internet sensation on the environmental Web site treehugger.com last month when he posted a step-by-step guide on building a homemade solar panel system for $105.Davis said he needed the free electricity to power tools and equipment on his property near Arizona's Painted Desert, where he relies mostly on a generator. He bought used and blemished solar panels off eBay for about $30 and strung together a bootleg unit that managed to power 60 watts of free juice, enough to recharge his drill overnight - a small but important step in the DIY quest to corral solar energy on the cheap.Davis' panels also received high attention on instructables.com, the San Francisco-based Web site that has become a popular destination for do-it-yourselfers looking for detailed instructions. Since the site added a green section last year, users worldwide have contributed more than 120 blueprints on green home improvement projects, everything from contraptions to convert attic heat into hot water to tinning a roof with aluminum cans.More news and press about Instructables here.

How much Mercury is in Compact Fluorescent (CFL) bulbs, watch batteries, and coal-fired power plants?

In Brennn10's Compact Fluorescent Instructable there was a short discussion about the amount of mercury contained in CFL bulbs. The same topic came up in a mailing list I read, and there was some interesting analysis worth sharing.Statement:The Stranger (the Seattle weekly) has a column called "Dear Science" where the typically quite intelligent author argued that CFL bulbs weren't all that "better" for the environment because inevitable improper disposal put more mercury-n-shit into the environment. So unless you got all your power from a mercury spewing coal plant, you shouldn't use CFL's . And Seattle, getting a majority of it's power from hydro, shouldn't use CFL's.This was called into question for being selective analysis that encourages an attitude of "there's not currently a solution, so keep doing what you're doing", and elicited the following response:Just so I can bore everyone with what I think is the current level of knowledge about mercury and CFLs, here's some of the current information.NRCan did a study on how much mercury is actually in CFLs, and compares them to other typical consumer sources (e.g., watch batteries--if you throw one of them out, you've throw out five times as much mercury as in a CFL):http://oee.nrcan.gc.ca/energystar/english/consumers/questions-answers.cfm#mercuryAfter reading this, I actually worked out these numbers for myself on how CFL savings compare to mercury releases a few months ago. Of course, this is all more environmental destruction brand X vs. brand Y discussion that was being talking about.I was curious about what the numbers work out to, so I went to dig for some data; this is what I came up with.In 1999, about 1.75 trillion kWh were generated by coalEnergy Information Administration Annual Energy Review 1999, Figure 26In 1999, 47.8 tons/year of mercury emissions came out of coal-fired power plants.Source: U.S. EPA, Office of Air Quality Planning and Standards.1999 National Emissions Inventory for Hazardous Air Pollutants.http://www.epa.gov/ttn/chief/net/1999inventory.html#final3haps.This calcs out to a figure of 0.025 mg mercury per kWhAssuming 5 mg mercury per CFL, the equivalence point is about 200 kWh--a CFL would need to save 200 kWh before getting tossed in the trash. A quick calculation shows that this is about how much a CFL saves in half a year, if it were run 24-7: 75 W for an incandescent; 25 W for an equivalent CFL = 657 vs. 219 kWh/year, or 438 kWh/year difference.Of course, this assumes that the coal mercury emission rate is the same as it was in 1999; I'm not sure if measures have been taken since then to reduce mercury emissions. Also, this is assuming that 100% of the power saved by the CFL would be generated by coal-fired power plants. But even with that assumption, coal is such a large fraction of the power generation (typically about half)--it would jump from six months to a year, instead. Of course, this period gets longer assuming a realistic duty cycle, but still, those numbers all seem to pencil in below typical installed lifetimes of CFLs.Finally, there's a article from Home Energy magazine (behind a subscriber link), where somebody did a similar calculation with more current numbers, I think.http://www.homeenergy.org/article_full.php?id=457&article;_title=Understanding_CFLsHome Energy MagazineNovember/December 2007Understanding CFLsby Richard Benware"Although the use of CFLs is steadily spreading, public understanding about how to dispose of them responsibly has not kept pace."Life Cycle BenefitsIn order to disprove the myths about CFLs, let's begin at the beginning. When CFLs are created, manufacturers dose the bulb with a small amount of mercury. This mercury, when electrically stimulated, releases UV light, which subsequently reacts with a phosphor coating to create visible light. Thus mercury is an essential part of every CFL; without it, the bulbs would not produce light. The typical dose of mercury is about the size of a pen tip, and these doses have been getting smaller and smaller. One reason for this is that the laws resulting from the Restriction of Hazardous Substances (RoHS) Directive have made it illegal for CFLs in Europe to contain more than 5 milligrams (mg) of mercury.In the United States, there are no such laws limiting the amount of mercury in lightbulbs as yet, but members of the National Electrical Manufacturers Association (NEMA) have voluntarily agreed to limit the amount of mercury in the CFLs that they produce to 5 mg for bulbs of up to 25 watts and 6 mg for bulbs of 25 to 40 watts. The average CFL on store shelves today contains about 4 mg of mercury, and nearly all the CFLs in production contain less than 5 mg. The mercury used in all the CFLs produced in the United States represents 0.18% of the mercury used in all U.S. products andindustrial processes.CFLs do not release mercury as long as they are intact. In fact, they reduce net mercury emissions in the environment by conserving energy. For every kWh of electricity used by consumers, the average power plant emits over 1.5 lb of pollutants. If a 75W incandescent is replaced by an 18W CFL, the CFL will use 456 kWh less energy than the incandescent over its 8,000 hour lifetime. The Emissions and Generation Resource Integrated Database (eGRID) contains data on the emissions of the average power plant. Using eGRID's information to calculate the average emissions per kWh, we find that this single CFL has prevented the release of 2.72 lb of sulfur dioxide, 1.05 lb of nitrogen oxide, 5.67 mg of mercury, and over 700 lb of CO2.It is important to note that these are the reductions from the average U.S. power plant. The eGRID data show that, on average, nonbaseload emissions tend to be dirtier. And in addition to reducing emissions, CFLs save money for the consumer. The Energy Information Administration (EIA) gives a 2006 average residential electricity cost of $.1008/kWh. Using the example given above, and basing our calculation on this figure, we find that a consumer would save about $46 on energy over the lifetime of the CFL.When these bulbs finally do reach the end of their useful life, there are several pathways they can take. In the best-case scenario, the bulbs are recycled. Recycling rates are increasing, thanks to state regulations -- California and Minnesota have banned altogether throwing CFLs in the trash -- and improved consumer awareness. In 1999, it was estimated that only 15% of all fluorescent lightbulbs were recycled. Currently, that number has increased to around 25%, with higher levels in commercial applications. Since an average of 98.9% of the mercury is successfully recovered in the recycling process, this pathway generates minimal emissions.Even the CFLs that are discarded in the trash are unlikely to release much of their mercury. Although most of them break under current trash disposal methods, some remain unbroken, and will not release any mercury. But those that do break are not likely to release much mercury. EPA estimates that only 0.2% of the remaining mercury in a spent bulb is elemental vapor. The rest of the mercury is in the glass, the phosphor coating, and the electrodes of the bulb. Mercury absorbed in these areas is not readily released. In fact, an EPA study found that only 6.8% of the total mercury in a broken bulb will be released. Since the average bulb on the market today contains only 4 mg of mercury, it will release only about 0.27 mg, even if it breaks when it is thrown in the trash.The only disposal option that could lead to the release of any significant amount of mercury is incineration. Today, many incinerators have advanced mercury control technologies. CFLs disposed of in such incinerators would release up to 90% of their mercury, but those emissions would then be removed by these technologies. Incinerators without these technologies are not capable of removing the mercury. But even after accounting for all of the emissions that occur via all of the routes listed above, CFLs represent a mere 0.01% of total U.S. mercury emissions annually.It is important to note that even if CFLs released all of their mercury, the environment would still be better off than it would be if nobody used CFLs. This is true because the average power plant releases 5.67 mg of mercury to power each 75W incandescent bulb. In short, replacing incandescents with CFLs is a great way to save energy, reduce mercury emissions, and save money (see "Discounting CFLs").
