Generation 6 COBs with industry leading efficacy exceeding 150 lumens per Watt (lm/W) at 3000K, 90 CRI, with the highest reaching over 184 lm/W at Tj=85°C. The use of traditional nitride phosphors in the Gen 6 COBs delivers high reliability and an expanded operating range as well as chromaticity stability over temperature, current, and time. These COBs are ideal for lighting applications including retail, hospitality, residential, commercial, museum, high and low bay lighting, and more. Special color options, such as Sensus™ below the black body curve for whitening warm color temperatures, AccuWhiteTM color rendering to 97 CRI typical, and hospitality color points are all available. With Light Emitting Surface (LES) sizes that range from 4mm to 32mm available in a full range of color temperatures and CRIs, these COBs can be used effectively for both indoor and outdoor applications. LM-80 testing confirmed the parts are capable of achieving Design Lights Consortium (DLC) premium lumen maintenance requiring greter than 90% lumen maintenance for over 36,000 hours of operation.
