A lightweight, long throw, all purpose lighting device the 8" fresnel produces a soft edged beam which varies in diameter from 6.3 feet to 25 feet at a throw distance of 30 feet for the 75Q and 175Q. The 75Q and 175Q are designed for operation with the long life, high intensity tungsten halogen lamps. The Luminaire is used in theatre for acting area lighting where beam shaping is not required or in television studios for key and backlighting. Other uses include nightclubs, museums and show windows where soft edge controlled lighting is required.
