This is a Kobold Fresnel Lens designed to fit the PAR reflector of a DW800 HMI fixture. It gathers, narrows and intensifies the light emitted from the fixture. It has a stay-cool handle for easy installation and removal. When mounted to the front of the DW800, it will cause the fixture to throw a 44° beam of 238 fc 13' (4 m), 152 fc 16.4' (5 m) and 38 fc 32.8' (10 m), in spot position. It will provide a 71° beam of 126 fc at 13' (4 m), 81 fc 16.4' (5 m) and 20.5 fc at 32.8' (10 m), with the fixture in the flood position.
