The L-Grid 2X2 LED GTR3 Series from US LED is designed specifically for recessed grid ceilings, and can be completely installed in a few easy steps. The installation must only be performed by a licensed electrician following the NEC and local codes.
To begin, turn off power to the appropriate circuit at the breaker box. Next, remove the cover from the power supply assembly by loosening the screw, and locate desired positioning for the fixture in the ceiling grid. Then, connect branch wires to corresponding black and white wire leads from the power supply.
