Strand Patt. 52 is a compact 1,000 W tungsten optical effects projector for stage, auditorium and exhibition use. It projects rotating effects discs (clouds, fire, water, rain, etc.) through a condenser-based optical system and also supports stationary slide projection via a slide carrier/turntable front rather than the effects attachment. Supplied as lantern + effects attachment + objective lens, it is designed for stand or suspension mounting with interchangeable optical discs.
