The Cavern fixture is specifically designed to accommodate an ultra sonic occupancy sensor. The unit can be configured with a wide variety of lamp and ballast combination that can switch or dim the fixture. A field configurable dimming ballast can be supplied that allows for the installer to control the light levels to minimize the unoccupied light level while maintaining life safety codes.

The Cavern features machined ends and a heavy gauge aluminum housing. The Cavern Lite is made from .040 Aluminum while holding the same shape and distinction that has made the Cavern so popular.
