The lighting unit consists of an upper body that is screwed onto the base using internal thread; therefore, there are no outside bolts or screws holding a cover in place.

The two part body is sealed using an o-ring thereby conforming to aseptic design.

The electrical connector is available as a 3 pole or 4 pole units. The 4 pole model allows for the switch and the bulb to be controlled separately. The switch provided can transmit a signal to a time relay that controls the on/off cycle of the bulb. This allows for automated control of the lighting unit from external sources.
