Cree's New Lab LED Breaks Barriers With 254 Lumens-per-watt

Based on silicon carbide technology, this milestone exceeds Cree’s previous R&D industry record of 231 lumens per watt

Cree says it has delivered another industry first with a whopping 254 lumen-per-watt white R&D power LED.

Elements of Cree’s SC³ Technology Platform, used in Cree XLamp LEDs, enable this "record-breaking" R&D result. The SC³ Technology Platform, built on Cree’s advanced SiC technology, features advancements in LED chip architecture and phosphor, and boasts a new package design to deliver the most advanced LED components in the industry.

Cree reports that the LED efficacy was measured at 254 lumens per watt, at a correlated colour temperature of 4408 K. Standard room temperature, 350 mA testing, was used to achieve the results.

“The latest innovation from our R&D labs is another game changer for the industry," says John Edmond, Cree co-founder and director of advanced optoelectronics. “The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption. Higher-performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs."
