The PT-VMZ51 produces an impressive 5200 ANSI lumens brightness great in a bright room and large conference room. The laser light source is perfect for high use environments with a life up to 24000 hours it can be simply abused with 8 hours of use per day every day of the year and still last over 8 years. With a wide ranging 1.6x optical zoom the PT-VMZ51 is also a great candidate to replace an older lamp projector in the same position without having to worry about rewiring. Panasonic have also backed it up with a stellar warranty for 5 years or 10000 hour of use for long term peace of mind.
