Today Cree unveiled a concept LED light bulb with seriously impressive numbers. Third party testing confirmed the delivery of 1,331 lumens at 8.7 watts with a CRI of 91 and a warm color of 2800 K. With these numbers, the concept light bulb exceeds the 21st Century Lamp requirements in the L Prize competition, according to Cree.
The LED delivers an astonishing 152 lumens per watt (1,331 lumens/8.7 watts).
By comparison, a standard, 75-watt GE incandescent puts out about 1170 lumens for a dismal 15.6 lumens per watt (1170 lumens/75 watts). The recently-announced Philips 75-watt replacement LED bulb, which uses 17 watts, puts out about 1100 lumens for a better 64 lumens per watt (1100 lumens/17 watts).
So with this concept bulb by Cree, we’re talking about a whole new level of performance. Cree’s concept uses TrueWhite technology with light that is similar to an incandescent.

Nice modern shape, with no bulge at the base to get hung up on tight fittings. Sweet.
I’ve found that Cree is almost entirely unmatched when it comes to quality of LED lamps. I bought one of their LR6 can lights when they first came out, nearly 4 years ago. It’s been in place at our office’s rear entry 24/7 light. Checking with a lumen meter, over the past 35,000 hours of use, I’ve only seen a 5% drop in lumens.
Since then, I’ve installed some 30 of them around the office or my home, without any problems.
Most of the no-name Chinese knock off LED crap I’ve bought loses 50% of its lumens within about 5,000 hours. I’m very excited to see this Cree product come to the market.
I’ve heard and seen the same about the LR6. This new concept is not a new commercial offering yet, but it’s nice to see what’s possible..
Nice looking bulb. Would look quite nice naked. I bet we see these in some modern architect designs, with those cheap $2 porcelain bases, just like in the image. Now, I’ll have something to replace my 150 watt G40 bulbs.
How about how long it lasts and cost and availability info.. I’m interested, but poverty level low income so if its expensive i need to know it will last long enough to justify the cost.
