Battle of the Bulbs!

Whilst looking through the recent -ibles i saw CYNICALifornia's variation to the light bulb lamp. Running, er, clicking as fast as I could, I got to the home page and saw that his -ible was featured as well, as I scanned the page I saw, parallel to his, My -ible! IT'S ON!!! not really, I just thought it was funny that they were both featured, almost the same -ible, and right next to each other..

Fluorescent bulb questions ? Answered

Hello, Short question but sorry,  I cannot seem to shorten it; the actual question is in the last two lines . My friend's outside light stopped working; Earlier today I was asked to replace the two bulbs; they had stopped working and seemed slightly brown on the ceramic part. They are four pin fluorescents; I have not used these type before. I went to Screwfix and their catalogue showed two bulbs that looked identical to the original but one model said for electronic ballast only and one type said for magnetic ballast only; the shop staff did not know what a ballast was and could not advise me, when looking at the original, which type to buy. I went to Toolstation , no such distinction was made in their catalogue; I asked the guy about the ballast suitability; he did not know what a ballast was; I bought the one that seemed the closest in name. I have never has to think about ballast types before buying a bulb before; but after buying the bulbs I found a sticker on the lamp saying -electronic ballast. I stuck the first bulb in, it did not light. I put the bulb, instead, into the next socket; it lit and stayed lit. I put the remaining bulb in the first socket and both bulbs stopped working; whatever combination that I tried. The original bulb was an Osram Dulux D/E 26w/840 The  new bulb is a  sylvania lynx-de superia 26w 840  G24q-3 Technical Details Brand Sylvania Item Weight 9 g Product Dimensions 16.6 x 3.6 x 3.6 cm Item model number 25927 Part Number 0025927 Colour Cool White Shape Stick Maximum Compatible Wattage 26 watts Voltage 240 volts Specific Uses General purpose Batteries Included? No Type of Bulb Compact Fluorescent Light (CFL) Cap Type G24q EU Energy Efficiency Label A Luminous Flux 1800 lumen Wattage 26 watts Wattage 26 watts Bulb Features Low energy plug-in compact lamp Colour Temperature 4000 Kelvin Colour Rendering Index (CRI) 85 Average Life 10000 hours Average Life 15000 hours Bulb Length 167 millimetres Warm Up Time 30 seconds Lumen Maintenance Factor at the End of Life 95 I still do not know if it was the correct bulb or not but . . . Here are the questions:   Are some bulbs suitable for both types of ballast ? What happens if you put the wrong type in; does it just not work; or does it blow the bulb; or/and does it damage the lamp? Thank you

Does anybody know how to fix an economic light bulb from blinking?

I've started changing the light bulbs at home. I want to use economic ones like the one in the picture. The only problem that I have is that when I turn off the light , the bulb starts blinking. I have a power switch similar to the one in the picture. It has a little lamp behind the red dots that goes on when you turn out the light. It helps you find the switch in the dark. I heard from someone that the blinking is related to this lamp. Does anybody know how to fix this? without removing the little lamp in the switch

Light Bulb Lamps

Oh what to do with the light bulb now that you're basking in the efficient glow of your CFLs? Well, you could convert them into these light bulb lamps as Sergio Silva has done. It's a pretty sweet item with neodymium magnets holding them in place on an included acrylic plate with embedded bits of steel.However, the price tag is $650 for the set which is pretty flippin' ridiculous for what can be remade with scrap and $10 of materials, if that. To be fair, the light bulbs Silva makes are sturdier than the regular item, are all made by the original artist, and are limited to a run of 66. So you're buying some design-y street cred before they get knocked off and sold for one-tenth the price. Linkvia bbgadgets

midflex idea bulb

I was in my quantum class today taking in some nice Schrodinger equations. The professor was having a hard time figuring out which students were understanding the material. I thought to myself, "Wouldn't it be nice to have a consistent way to show the teacher you understood." So then it hit me... why not have a classic idea bulb on top of a hat. You could push a button and it would light up. Thus indicating to the teacher that you understood the material. Simple enough, but kind of annoying to push a button every could of minutes. Why not use the new Mindflex toy to gauge your understanding of the material? The user could wear the headset like usual. Instead of controlling a ball like in the game, a sudden decrease in concentration (the realization of an idea) would turn the light bulb on. The electronics should be simple enough. It would obviously be better to use an LED instead of an actual light bulb. I would build it myself, but I don't want to spend $60 on a mindflex game. What do you think? Elijah

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.

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?

DIY Projector bulb problem ?

In reading some of the instructables on DIY projector lamp replacements I decided to give it a shot. So I purchased a Proxima Ultralight LX1 off of ebay, and when it arrived it contained no previous bulb, so I purchased a MR16 style 100 watt halogen bulb and installed it (with a seperate power supply). When I started it up and connected it to my laptop it worked fine for about a minute or so (give or take) but then the image went blank (not the bulb but the LCD screens showed blackness) for five seconds, then the image popped up as nothing had ever happened. I have tried everything to prevent this, other computers, killing the ballast (which is quite easy, only one wire to disconnect) different video sources and no dice. But I do know that it has nothing to do with the light bulb because it is on a completley different power supply and is not connected electronically to the projector in any way, there is something wrong with the controls of the unit Any Help would be appreciated, Thanks Bwpatton1

LED Lamp Buzzing (not a bulb)

About a year ago, I came across this LED lamp that was on sale at my local Target store. It caught my eye because it had a little tray at the base of the lamp along with a USB port for charging my devices. Since the first time I plugged it in and turned it on, it makes a buzzing noise. At first it didn't bother me, but now that I am spending more time at my workbench it has become annoying. I understand it is kind of common for LED bulbs to do this because of the dimmer switch being outdated, however this lamp is not dimmable nor is it a "bulb" so to say. It's about 7-9 SMD LEDs on a circuit with a rocker switch. If it makes a difference, I do have my lamp plugged into a surge protector and don't have anything plugged into the USB port located at the base of the lamp. What can be done (other than throwing it away, of course) to stop the buzzing noise coming from the lamp? Thanks in advance!

why do halogen lights keep blowing? Really scared of fire!

I live in a rented attic flat and just before Christmas four of the ceiling halogen spot lights in my hall and livingroom blew.  I called the landlord (he is an electrician) and he replaced them - then charged me £50!  Two days later the same lights blew again.  There seems to be condensation or something around a couple of the bulbs. (They are sunk in the ceiling.) The next day I went away for two weeks for Christmas, came back yesterday and this morning there was a 'pop' noise and all the five lights in my bedroom blew. (I hadn't just turned them on. They were already on.)  I can't locate the fuse box and I am worried about an electrical fault causing a fire.  It is a new flat (five years old, and the landlord did all the wiring - he is an electrical contractor.) I have to be out all day tomorrow, leaving my little dog there, and I am scared there will be a fire.  I am going to speak to him tomorrow and try to get him to come and sort this out tomorrow night when I get in, but it took ages to get my landlord to come and sort the last thing out, I am living in semi-darkness, and I can't afford to pay hundreds of £ every time the bulbs go.  I have only lived there three months.  What should I do?  Is it safe? I would feel better if I could turn everything off at the mains before going out tomorrow, but I don't know where the thing is to do this - and I don't want to meddle with stuff I know nothing about.

Troubleshooting Christmas Mini-Light Strings

I searched Instructables to be certain I am not covering something someone else has already done, but found nothing.  Here is an excellent article on troubleshooting a bad string of Christmas mini-lights. (I do not know the author and am not connected to him in any way.)  I know of three occurrences of non-working light strings from this year's celebrations. In the first case, the woman who owns the Christmas tree simply bought a new string of lights and hung the new lights over the old string attached at the factory to her synthetic tree. I did not see her tree and cannot say what the cause of the malfunction was. In the second occurrence we put up a synthetic tree with two strings of factory installed lights, one for the bottom half of the tree and one for the top half of the tree. The string on the top half worked some of the time, but then would go out. Typically one suspects a bad bulb. That is also the general suggestion made in the very fine article I linked above. However, that proved not to be the problem. Rather, the problem was the very cheap electrical plug. I cut the plug from the string so I could open it and determine exactly where and how it failed in order to satisfy my own curiosity. Installing a new male plug solved the problem. In the third case, my daughter had a string near the top of her tree that was "out," but not completely at the top. I had limited tools and resources, but plugging the bad string into a different molded female plug brought it back to life. The moral of the story is that while a bad bulb is a frequent source of problems, the molded male and female plugs on these inexpensive light strings are often held together only by a lick and a promise, and fail easily. Giving the molded plugs a hard look is much easier and faster than removing and testing bulb after bulb. The first photo shows an extension cord with molded plugs from three strings plugged into the extension cord. The second photo shows the bad male plug on our tree, and I am using my multi-meter to test for continuity between the brass plug blade and the load end of one of the tiny fuses inside the plug. That part tests "good." The other fuse tested "good," too. In the third photo I inserted a straight pin into the wire and tested for a circuit from the brass blades to the wire. Both sides failed this test.  A multi-meter can easily test what I needed to find this problem. I would have needed to strip away some insulation from the wire or stick a straight pin through the wire to obtain a reading with my multi-meter. But, by this time I had bought a hum tester with a high and a low range for checking different voltage ranges on an AC circuit. It led me to know the plug was the problem.
