Cree Raises Industry Standard with New 170 Lumen-Per-Watt Prototype LED Light Bulb

Less than one year after showcasing the 152 lumens-per-watt concept LED bulb, Cree, Inc. delivers a new performance benchmark with the 170 lumens-per-watt (LPW) prototype LED light bulb. The innovations behind the high-performance 170 LPW LED bulb are enabling significantly higher efficacy and lower cost for Cree's luminaire portfolio and demonstrate Cree's continued commitment to accelerate the adoption of LED lighting by addressing initial cost and payback - key barriers to widespread LED lighting adoption.
LED lighting at this level of performance is only made possible by advancements across all elements of the LED lighting system - lighting-class LEDs, optics, drivers and thermal management. LEDs based on Cree's innovative SC(3) Technology Platform enable this industry-leading R&D lighting result. The SC(3) Technology Platform is built upon Cree's advanced silicon carbide technology and features advancements in the LED chip architecture and phosphor.
Third party testing by independent lab OnSpeX confirmed that Cree's new 170 lumen-per-watt prototype LED bulb delivered more than 1250 lumens and consumes only 7.3 watts. The bulb uses Cree(R) TrueWhite(R) Technology to deliver a CRI of 90+. As an efficiency comparison, a traditional 75-Watt incandescent light bulb produces 1100 lumens, which is only 14.6 lumens per watt.
