Let there be extra Lumens!

Lithonia flush-mount LED fixture Mod

Since the original Lithonia LED fixture is not bright enough to illuminate my living room, I have added extra LED strips (4-foot long in total) along with two 12W LED driver. The drivers are manufactured by Illuminous, and 'Triac-dimmable'. Pretty cool, huh? They also worked greatly with my Lutron wall dimmer. On the back of the fixture, i.e., on the wall-side, I had to add extra heatsinks to dissipate extra heat. Anyhow, extra Lumens do not come for free. Thanks to the heatsinks, I managed to suppress the fixture temperature under 71 dec Celsius at the steady state (measured after two-hours continuous run).
