Utilizing four high-output 330-watt NSHA lamps as its light source, the PLC-XF47 delivers an amazing 15,000 ANSI lumens of brightness. Stacking two projectors in the twin-stack configuration can achieve up to 30,000 ANSI lumens of brightness. PLC-XF47 contains a durable liquid crystal panel for extended projector usage and combined with a high-contrast optical system that achieves a contrast ratio of 2000:1. A newly developed liquid crystal panel with an optical compensator that creates linear polarization, together with improved optical block cooling system, gives the PLC-XF47 the capability of being operated on a 24/7 basis.
