Hmmmm….could be. Cree just announced they have achieved 1000+ lumens from a single-die XLamp LED driven at 4 Amps yielding a luminous efficacy of 72 lumens/watt which is about the same output level of a standard fluorescent lamp. Wowza! That is a lot of light but at the same time, that is a lot of current when you consider that most of today, commercially released high-power LEDs are driven at about 350 mA. I would really like to see the cooling that was employed. I’m thinking cryogenic perhaps or BHF’s (Big Honking Fans) maybe? How long did the XLamp last before it ruptured the space-time continuum and disappeared or melted into a pool of molten semiconductor?
Anyrate, the disclosure is very positive news for Cree and the LED industry at large. It’s only a matter of time now before LEDs are the defacto-standard in home lighting.
