Cree XP-L LED delivers 200 lumens per watt
By Alyssa Dalton
July 4, 2014 – Cree says it has introduced the first commercially available single-die LED to achieve breakthrough efficacy of up to 200 lumens per watt (LPW) at 350 mA.
Delivering up to 1226 lumens in a 3.45mm x 3.45mm package, the XLamp XP-L promises an immediate performance increase of 50% or more as a drop-in upgrade for lighting designs. As the brightest member of the industry’s only family of high-density class discrete LEDs, the XP-L LED also touts the industry’s highest optical control factor (OCF), a measurement of the impact that LED size and performance have on directional lighting applications, says Cree. Characterized and binned at 1050 mA, 85C, the unit is available in up to 90 CRI and colour temperatures ranging from 2700K to 8300K.
