Color Controllable High Power Lighting - no longer for billionaires only! Build your own fully color controllable RGB room or spot lighting for under $100. Perhaps you are asking yourself: "why would i want an any-color light?" well, for starters you can give your pets a virtual color make-over! ever wondered if Fido might look better in purple? perhaps you'd like to see your makeup the way Bono's seeing it with those blue-lens sunglasses? or maybe you're sick of your almond-white wall paint and want to give it just a tweak of eggshell today? of course, it's a gimme for the dance-party, but you can also use it to tweak the shade on your existing room lighting, or as a standalone to get any shade of white (and perfect color rendering) - invaluable for visual arts. in search of an existential crisis? i just spent a good half an hour with this light staring at my hand and trying to figure out what color it is *supposed* to be. Recently i've been using it as a portable personal light-space. you know - you walk around with an ipod to have your own sound-space, no you can walk around bathed in your own personal color too!
- Controller can power up to 360 watts of LED lighting - between 3 and 100+ power LED's
- Analog dial or slider for Red, Green and Blue - create an infinite number of light colors!
- easy to make a room light or a spot light by switching lenses / covers
- very fine analog control for precise color matching (or white matching)
- Includes current-limiting protection circuit
- Simple 7-component thru-hole circuit - No microcontrollers or programming!
- Controller cost: $25
- 50-watt, 15-LED lamp cost: $50
- Efficient: 50 watts of LED light equals 100 to 150 watts of incandescent light.
- Efficient: 80-90% controller efficiency
- Controller can be used with a variety of power sources
- Recycled materials & electronics: 20-40%
I've included a lot of detail in this instructable that applies to any power-LED project, and i've got several other power-LED instructables
too, check those out for other notes & ideas.
why not digital?? this controller was specially designed to be as simple as possible by using analog-only. it turns out that it works really well. yes, a digital PWM controller is "better", but it requires "chips" and is thus more complicated to build. i've included a circuit for a digital PWM controller here
