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.

Im for some sort of heating source to boil water in a lightbulb. I initially was thing an immersion heater but thy are too large. which has lead me to thinking along the lines of building an external coil to do so. Would this feasibly work? And if so how would i go about doing so? Any input would be a great help or any other ideas on how to go about heating are welcome as well

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

I would like to make a display where incandessant bulbs throb like they are being powered by a varying vlotage. The bulbs would be 75 watt or 25 watt depending on what I end up doing. I am even considering some 30 watt edison type bulbs. How do I make a controller for something like this?

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.)

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.

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 :)

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

Has anyone ever made a room furnace with a light bulb? I've heard of using light bulbs contained in a metal box. Answered
Any ideas. This principle could work along the same lines as an oil hot water heater pumped through a radiator (you know those 300 lb.+ radiators from older houses), but using the bulb in place of the hot water.. If it was portable, that would be great. I could make a nice cover or wood cabinet around it myself. What would be a good metal to line it with that could magnify the heat of a light bulb. Obviously, this would need to be a safe product. Getting a little warm on the outside is not a problem in our home. I mostly just need some idea as to what metal to use to magnify the heat of the bulb. Thank you in advance for any help or ideas.

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.

Asked by cd41 9 years ago
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 :^)

Hello, i had an idea today. A light powered by a solar panel that powers itself! You would need a small amount of energy to initiate the circuit's current, but i can only see one way why this could not work: Lightbulbs lose some energy as heat and a tiny percentage as sound. How could you counter this? Heat collectors? Any ideas? I think that I may be on to something here!

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

My solid-state relay keeps blinking a lightbulb while in the inactive state, how can I eliminate that?
I have a DC controlling AC solid state relay connected to an arduino diode for control and a light bulb to the 220 side. While there is no signal coming from the arduino the bulb is blinking insanely fast, when there is arduino signal, the light remains constantly on as intended. How can i make sure there is no load at all on the 220 end while the relay is inactive, so there is no light flickering? Relay specifications: Control: 3/32VDC Output: 48-480VAC 50/60Hz Thanks in advance!

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.

Basically, I want to control multiple application using a smartphone to an Arduino. If I want to control lightbulb, security camera, garage door, and security sensor, can I use only 1 Arduino or I need 4 Arduinos to connect to 4 applications? Is there a specific Arduino board should I use? Do you recommend of using an Arduino BT since I am connecting it to a smartphone?

It turns on, heats up for about 1 to 10 minutes, then click, turns off. What can cause this? I usually unscrew the light bulb so it does NOT come on during the cycle, I like to sit in the dark and sweat! When I screw lightbulb to turn on, unit immediately clicks off. I have been having some panel problems where the time keypad or the temperature keypad will not respond as well.

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.
