REVELATION VIDEO PROJ LIFT MODEL A W/O PLENUM With a Revelation the projector is permanently concealed above the ceiling. You won't see or hear the projector - not before, during or after the show. Now the Revelation is more compact and easier to install! The improved Revelation truly fits into a 2' x 2' grid style ceiling. It can also be used with a reveal style grid ceiling. To increase space for the projector (especially those with offset lenses), the company has removed panels on the sides of first mirror. Draper has also upgraded the Revelation mirrors to 10 mm thick for optimum flatness and reflectivity. Mirrors are optical grade glass - 94% reflective. The Revelation's highly reflective dual first surface mirror system delivers a perfect picture to your screen at the touch of a switch or wireless controller.
