Easy install. Incredibly bright 8000lm

I purchased the Troffer retro fit to replace the T8's above my workbench. I could not believe how much more light these produced. This reto fit is so bright there is no shadowing. I have a woodworking shop and some of my measurements are down to 1/64 on a rule. Sometimes while measuring my head will be in the way of the light to see the measurement clearly. That issue is gone with the Troffer retro kit install. I will be buying more for the rest of my shop. The magnetic led strip that comes with the kit is awesome, no tape to deal with, attach to inside the fixture.......DONE. The power supply also has wires to accept a dimmer switch, Awesome again.

Great for indirect perimeter lighting upgrade

I used these to replace 18' of indirect lighting around a large multi-purpose room. Got rid of old T12 ballasts and re-use the existing trays to mount the light strips. Easy wiring. Lights are bright and natural light color.
