Cree XLamp XT-E White LEDs are the highest-performance white LEDs available. The XT-E LED delivers twice the lumens-per-dollar of previously available LEDs in the popular XP footprint. By leveraging the popular XP footprint, customers can easily incorporate the XT-E LED into existing XP LED designs to shorten design cycle and improve time to market.

Built using the latest generation of Cree's silicon carbide based LED chips that deliver higher flux and efficacy, the XLamp XT-E White LEDs set new standards of efficacy, light extraction and quality. Designed to accelerate LED lighting adoption, the XT-E LED delivers up to 148 lumens and 148 lumens per watt in cool white (6000 K) or up to 114 lumens and 114 lumens per watt in warm white (3000 K), both at 350 mA, 85°C.

Features

• XP footprint: 3.45 X 3.45 mm
• New generation of Cree's silicon carbide-based LEDs
• Characterized and binned at 85°C

Lighting Applications

• General and directional lighting applications
