[. . . ] Welcome to the future of high-lumen projectors. 4000 lm WXGA 4500 lm XGA Operation simplified with Mitsubishi Electric's user-friendly design Low Maintenance & High Durability New Color Wheel System Dust can easily accumulate on the color wheel sensors of previous models. But the sensor in now mounted in the rotary shaft motor casing, which is almost fully enclosed, making it much less likely for dust to collect on the sensor. 100% Electrode Abrasion New Lamp Drive System Arc Discharge Electrode Previous color wheel illustration Photo Sensor Timing Mark New color wheel illustration Fixed Halleffect IC Initially, the gap between the electrodes is small and the arc density is high, resulting in high brightness. The distance between the electrodes increases as they wear causing a decrease in arc density, which also results in a loss of brightness. [. . . ] The distance between the electrodes increases as they wear causing a decrease in arc density, which also results in a loss of brightness. Conventional Lamp Drive System New Lamp Drive System Optical Signal Dust accumulates on the sensor and thick part of the timing mark blocking the path of the light when using the light signal method. This interferes with the color distinction process, causing poor color alignment and breaking. Magnet Less than 1mm Magnetic Signal The base spins together with the color wheel. The wind pressure created by the centrifugal force keeps dust from entering through the gap (less than 1mm or 1/25in). The magnet is embedded in the base, so there is no protruding part for dust to accumulate on. Even if dust does accumulate, since a magnetic signal method is used, the signal passes through the dust without any problem of color distinction. 0% Total Lamp Usage in Hour Adoption of a new lamp drive system prevents electrode wear, giving the lamp a longer service life and enabling it to retain projection brightness over a longer period of time. Filter free DLP projectors are structurally airtight, therefore an intake filter is unneeded, eliminating filter changing and lowering costs. TM Up until now, the electrodes in the lamp deteriorated more quickly when using the projector for long periods of time, resulting in a loss of brightness. These projectors incorporate an optical design that optimizes lamp operation to realize a lamp drive that makes it possible to stabilize the shape of the electrode during long-term use. As a result, the maximum lamp service life is obtained for every projection mode and loss in projection brightness is extended over a longer period of time. Long 4000hr Lamp Life The WD3300U/RD-JT31U has a lamp temperature controlling system that enables a lamp life of up to 4000hours. *1 Long-life lamps make dramatic reductions in overall cost of ownership by reducing the frequency of lamp replacement. Lamp Replacement Frequency*2 2, 000hr lamp Original Lamp 4, 000hr lamp Original Lamp 2, 000 hours 4, 000 hours 1st replacement Reduced Lamp Replacements Side Access Lamp & Center Lens Designs The lamp can be accessed from the side of the projector, simplifying the replacement process, as the projector does not have to be turned around when sitting on a shelf or turned over when suspended from the ceiling. *DLP (Digital Light TM TM Screen Size and Projection Distance / Optional Lenses Refer to the following table to determine the screen size.
