A Monster LED Array For Irresponsible Fun 225
Tesladownunder writes "This huge LED is on steroids and then some. It is intended for use as a streetlight. It has a 7000 lumen output at 100W and will burn a hole in a CD case without focusing. And that's without the infrared that a halogen or discharge lamp has. Very efficient and low maintenance. Stronger than HID car headlights or a 500W halogen. Hit the site for lots of data and pics of it in action including burning and irresponsible bicycle luminosity. You'll want one to attach to your keyring, too."

I actually bought some LEDs recently from the eBay seller he mentions. Some 250,000MCD 10mm white LEDs, some little DIP-package white LEDs, and some DIP-package RGB LEDs. I saw these LED arrays and I knew I wanted one of the 50watt 3500 lumen ones for a DIY 1080p projector build. (Also possibly to jury-rig an LED replacement for the $400 2000 lumen bulb in my BenQ projector)
The 7000 lumen one like he's playing around with would be nice if you want to build a projector that doesn't require a light-controlled environment, or is projecting a super-large image. (Or if you want to just burn shit down, lol) I imagine with that sort of output though, it starts to become a real heat problem for the LCD in the projector, just like a conventional bulb.
These days it's getting so that anyone with a little know-how and some cash can build nearly anything they want. Especially if you just built your own CNC milling machine. ;3

Great photos too. Look through his laser and HV section.
Amazing collection. Interesting character.

Oh, and in case anyone is curious about growing plants under LED lights, I've been documenting the experience here [gardenweb.com].
Net result? The UFO works better than the Xmas lights, but the Xmas lights do work. Everything but the lettuce and brassicas seems to thrive under the LEDs, and the lettuce and brassicas would probably thrive if they were right under the UFO instead of on the periphery. Some plants, like the pumpkins, have been acting like the LED light is steroids. So, if you want to grow plants indoors but don't want a huge power bill, I'd go with a UFO or two inside a reflective chamber.
And yeah, I know, most people just use them for pot :P

Anyone who needs their night vision use red and green lights.Once you hit blue and white it can take 10-30minutes for your eyes to adjust back. It is biology.
Light spectrum colors and their effects are known. Meat counters use pink lights, as if they used a bluish color the meat looks rotten. Take a good look Round yourself some day. Various shades of colored lights are used everywhere to promote different products. And for effectivedifference between HPS and white Metal Halide go to a mall parking lot and then to a car dealers. Notice which one hurts your eyes.
