The Type 6791 is designed for Motion Picture, Television, and Event Professionals worldwide. The combination cast and sheet aluminium construction features dramatically improved strength and cooling while the Brytal Aluminium parabolic reflector provides over 95% reflectivity. The new 12/18K Par uses the larger and safer G51 socket designed to dissipate more heat, and eliminate potential arcing between pins. In addition, this new lamp will be supported from the collar and not by the pins alone, thus improving reliability and overall lamp life. The electronics in the fixture are contained in a low-profile trough totally isolated from the main housing, and feature a swing-out trap door for easy access to the igniters and safety switch. The fixture has visual and tactile focal indicators to determine lamp position and, when used with the interchangeable lenses, the field of light can be fine-tuned for optimum beam control. Other features include: a trough skid for operating and safe transportation, an adjustable yoke pivot point, a locking, hinged front door for easy lamping, and a pig-tail style electrical input. Standard on all fixtures are a stainless steel safety screen, spring loaded fourth accessory clip, and variable accessory clip positions located at either 90° or 45°. Compatible with all existing 21” accessories.
