H66 COB LED

Features

1. High lighting efficiency: above 145lm/W.
2. Less than 4SDCM chromatic aberration, same light and same color, cool white
3. Widely used for high bay lighting, flood lighting etc.

Replace the integration modules, compatible with line holes and optical ports.

Aluminum COB PCB can avoid silver sulfuration effectively.

There’s a chemical reaction between silver & sulfur , and turns to Ag2S. It’s black and lower the light efficiency hugely, finally cause to dead light.

The reliability test between Evercore COB & Integrated ones in high temperature and high humidity condition (Ta=70℃, RH=85%). Evercore COB still remains higher lumen after 504H testing.

The lumen is higher with aluminum PCB because of the better reflectivity performance of mirror aluminum PCB.
