3-chip DLP projector. Panasonic's original dual-lamp system, with its new 380 W lamp, helps to make the body compact, while providing a full 12,000 lumens of brightness with 120 V AC operation. The replacement lamp unit (ET-LAD310A/ETLAD310AW) can be used with all of the PT-DZ8700/PT-DZ110X Series projectors. This reduces the number of lamp types that need to be kept in stock when multiple projectors are used. Panasonic's Dynamic Iris uses a scene-linking aperture mechanism to achieve a remarkable 10,000:1* contrast without lowering its high brightness. This helps to reproduce deeper, richer blacks and provides images with more detailed textures.
