They are already attached to a heat sink. It appears that they need to be thermally attached to a larger piece of heat conductive material for proper long term operation.

best hong kong is my first choice for leds, they sell on ebay and at their site. ( http://www.besthongkong.com )
led light output is not exactly measured the way traditional lights are. The brightness of an led is based on the beam angle the light is emited at, a narrow beam = a brighter light. 1000 mcd = 1 candela. candela is light emited, lumen is light recieved... candela to lumen conversion is ugly. most leds wont consume anything near a watt unless specially designed to that idea, best h k has 1, 3, and 5 watt leds... which is news to me, time for more leds. sorry if this was all ot or tmi... also, iv never had a heat problem with led's. the super brights can get a bit warm but even stringing a couple dozen together its not been an issue. |

Wow... They have 100,000 mcd whites!
I could cut the Cheez Whiz logo on the moon with a couple of those. |

350ma is an exceptional amount of current for an led.
yes that will run right around 1 watt. id be interested to get an led surface temp off of it when running 350@3.5 ... |

On the super bright LED's website, there is a 1 watt XLite that is UV. Would this help with flourescing corals? Or is that past the effective wavelength for giving corals the "pop"
Just wondering. -Jon

390-410 nm, should give you some results. I've used the 400nm 3mm at 4000 mcd. They worked pretty good.
I was building a nano tank with led lighting. I stopped when I heard a lot higher wattage and mcd's were coming out. |

I've built a few of these.
http://img.photobucket.com/albums/v4...oon_edited.jpg These are run on a 12VDC 500mW transformer. They are mounted to a metal clad PCB to reduce heat. 1 watters. VaderWS6, send me a PM I still have a few LEDs. Your on your own for ckt design. Its easy though.
