Luminus Devices SFT-40-WxS High Power White LEDs offer a flat window package that emits less light than a dome-shaped cover. The SFT-40-WxS allows smaller optics and higher optical coupling efficiency. The SFT-40-WxS LEDs produce a high lumen density similar to a monolithic emitter. In addition, the Luminus Devices SFT-40-WxS High Power White LEDs supply a powerful light source for beam pattern critical lighting applications, delivering extremely high intensity, long beam distance, and tight beam angles.
