The 100W 3" Fresnel Light from Altman is a lightweight, very short-throw all-purpose fixture that produces a soft-edged beam that varies in diameter from 4.2 to 10.4' at a throw distance of 10'. It's designed for incandescent and tungsten halogen lamps. It can be used in theaters for specials or in television and photographic studios for tabletop applications, among other uses where soft-edge controlled lighting is required. The light delivers 4450 spot (10° beam)/1475 flood (34°) candlepower (candela).
