A powerful yet compact illumination system for sanitary processing equipment provides up to 150 watts of adjustable illumination while allowing viewing through the same 3-A approved window. These unique combination units incorporate the MetaClamp™system with Metaglas® safety windows. They can be used to view the interior of either new or existing sanitary processing equipment. The illumination modules can also be used separately, mounted on any existing view port or other L.J. Star sight windows, providing adjustable illumination where limited space or connections make the use of conventional luminaires difficult.
