I installed 4 of these lights in an automotive service department of a dealership. The lights are suppose to be rated for 277v however I'm not so sure. 1 of the 4 lights burned out within 24 hours of installation. I'm the picture I attached you can see the LED driver looks like it is burnt. This is embarrassing and costs my business time and money to fix. Use a reliable brand these are not commercial grade. Also I'm pretty sure they don't meet UL certification requirements.
