Even if one lamp goes out during use, the other lamps continue, so projection is not interrupted.
Lamp Relay mode also allows long-time, continuous operation.
Brightness and Lamp Replacement Cycle Guideline
|Lamp||Brightness (lumens)||Maximum lamp replacement cycle (hours)*|
|Two lamps (Normal)||13,000||2,000|
|Two lamps (Eco1 or Eco2)||10,010||3,000|
|One lamp (Normal)||6,500||4,000|
|One lamp (Eco1 or Eco2)||5,005||6,000|
* The values above are maximum values when they are used in cycles of being turned on for 2 hours and off for 0.25 hours.
When the lamps are turned on and off more frequently, the lamp replacement cycle is shortened. The usage environment affects the lamp replacement cycle.
The LCD panels and polarizers inside the LCD projector's optical block tend to degrade over time. Their degradation adversely affects image quality. Inorganic materials are used for the LCD panels, and for the polarizers that are prone to degradation, to resist time-related changes in the optical block, therefore achieving a replacement cycle of up to 10,000 hours.
The use of a large pleated air filter has made it possible to achieve a replacement cycle of up to 5,000 hours.*
This greatly reduces maintenance hassles. The filter is also replaced from the front, so there is no need to detach
the projector from its bracket in ceiling-mounted applications.
* With the lamp power set to Normal. The usage environment affects the duration of the filter.
The projector can be equipped with an optional Smoke Cut Filter ET-SFE16 to prevent the entry of not only dust but also fine smoke particles, such as those used for special effects at events and stage performances.
