If your light switch is stuck on, or not responding, try the following:
If your light switch is a dimmable switch - engage the air-gap switch by gently pulling out from the bottom of the DIM/BRIGHT Bar until the bottom of the bar lifts completely out of the frame and a click is heard (refer to Figure). LED's will turn OFF.
This will stop power to the fixture and reset it. Wait 10 seconds, and push it back in, and this should resolve your issue.
If your light switch is an on/off, (non-dimmable) the air gap switch is located at the bottom. Gently pull it out from the bottom of the switch, until you hear a click, and the LED turns off.
If you are uncomfortable performing this manuver, you may reach out to the maintenance team.
