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.
