Tailored as replacements for traditional 40W and 60W bulbs, the Chip-on-Board (COB) LED series is a MCPCB substrate based multi-chip solution that delivers greater than 95l m/W at 3000K CCT and a greater than 80 CRI. Less layers of thermal resistance result in lower overall junction temperature. A patent pending innovation is able to address the hot/cold factor, the color uniformity as related to change in temperature. From 25°C to 85°C, the LED can control CCT shift to within 200K CCT for all wattages. EVERLIGHT AMERICAS INC., Carrollton, TX. (972) 490-4008.
