Cree’s XP-E2 LEDs doubles lumens/$ and boosts lumens/Watt by 20% over XP-E

LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has launched the XLamp XP-E2 LED, delivering higher lumens per watt and lumens-per-dollar to lower system costs for existing XP-E and XP-G designs. The new XP-E2 LEDs can increase the lumen output of XP-E designs for the same cost and power or lower system cost with fewer LEDs, enabling lighting manufacturers to deliver a better lighting system with minimal redesign, the firm claims.

“The price-to-performance ratio is an important consideration for our design process,” says Erik Milz, VP of marketing of LED lighting product maker TerraLUX Inc of Longmont, CO, USA. “Since many of our products are based on Cree XP-E LEDs, the new XP-E2 LED is a significant upgrade in performance, helping to keep design costs down and speeding time-to-market for our solutions,” he adds.

The XP-E2 LEDs use the same XP footprint (3.45mm x 3.45mm) and are optically compatible with all XP LED designs, including XP-E and XP-G LEDs. The new LEDs also enable a broad range of high-lumen applications, from indoor and outdoor lighting to portable and lamp retrofits.

As the latest products to be built on Cree’s SC3 Technology next-generation LED platform, the XP-E2 LEDs deliver luminous efficacy of up to 128 lumens per watt at 350mA and 85°C, or 143 lumens per watt at 350mA and 25°C in cool white (6000K). The SC3 Technology platform is built with Cree’s silicon carbide (SiC) technology, features advances in LED chip architecture and phosphor, and showcases a new package design tailored for lighting-class LED components.

Luminaire makers seeking ENERGY STAR qualification will have access to specification and performance data, including LM-80 reports, which can speed time-to-market, says Cree. XP-E2 LEDs are a ‘successor’ product to the original XP-E LED for LM-80 data, accelerating the qualification of luminaires using just 3000 hours of LM-80 data (instead of the normal 6000 hours).

Samples of XP-E2 LEDs are available now and production quantities are available with standard lead times. They are available in correlated color temperatures of 2700-7000K, with minimum color rendering index (CRI) options of 70, 80, 85 and 90.
