This Metalux is cULus approved for operating on a power supply of 100/277 voltage.
It's size is 2x4 ft or 600x1200 mm with a prismatic lens. It can hold 3 LED or fluorescent T8 tubes. You can add 3 LED tubes for additional cost of $15/tube.
This is for a drop ceiling so it can be mounted to be flush with the ceiling tiles. The lens door opens allowing you easy access for installing T8 tubes.
Future maintenance is a breeze since only the tubes needs to be replace and not the entire fixture.
