    New Cree LED Breaks Efficacy Records with 186 lumens per watt

    A new Cree prototype has already beat out their newest XP-G LED by achieving 186 lumens per watt in a white LED–making it the industry’s best R&D achievement to date. The LED put out 197 lumens total while driven at 350mA for the 186 l/w. The technology is extremely promising, but keep in mind the […]

    A new Cree prototype has already beat out their newest XP-G LED by achieving 186 lumens per watt in a white LED–making it the industry’s best R&D achievement to date. The LED put out 197 lumens total while driven at 350mA for the 186 l/w. The technology is extremely promising, but keep in mind the light emitted had a color temperature of 4,577K.

    This news will only continue to encourage LED applications in every day life and aquaria. We’re anxious to see these roll out of production.

      Cree announced the 150-ish lumen/watt engineering sample / R&D LED’s a few years ago. This does not mean it has the longevity we expect from LED’s, or the mfg. process figured out. Based on that last cycle, I would say it will take 2-3 years to bring this to market… which is a good thing. Over that time, it it very likely that an even higher efficiency is produced through R&D that can be applied… so it may be just over 200 lumens/watt, which is better, but I wouldnt bet on seeing these for a couple years. Computer companies have ‘testbed samples’ of microprocessors that hit double if not triple the GHz (or now cores) of our home computers, but that doesnt mean we will see anything like that for years to come.

      But what about CRI???? I can’t find any official information about CREE’s CRI. I try this on his site – but nothing – only somthing “about” “or” “and “………
