ABSTRACT:
The present invention provides for a pneumatically operated retractable lighting assembly that is adapted for insertion into the ground, existing ceilings, or the like. The pneumatically operated retractable lighting assembly includes a first housing that receives a second housing. The second housing is in a slidable relationship to the first housing. The second housing further supports the light fixture. When the device is activated, air is supplied to the first housing in order to lift and activate the second housing and current is supplied to the light fixture. During deactivation, the air escapes the first housing to permit the second housing to retract into the first housing while current is no longer supplied to the light fixture.
