Cleanroom light fixtures are available as either lay-in or teardrop fixtures. The light fixtures are welded and sealed on the top of the fixture. The door of the fixture is gasketed. Fixtures are available in either 120v or 277v and with or without electronic ballasts. The lay-in fixtures are heavier than commercial fixtures and compress the gasket in the ceiling grid to prevent air from leaking out of the room while preventing dust from coming into the room.
