Compatible Projector Models

This replacement lamp fits Hitachi CP-HS980, CP-HX990, CP-RS55, CP-RS56, CP-RS56+, CP-RS56W, CP-RS57, CP-RX60Z, CP-RX61, CP-RX61+ and PJ-LC7 projectors. It is intended for owners of these specific units who need to restore brightness after the original lamp reaches end of life. Buyers with other projector brands or models cannot use this part.

Maintenance Timing Benefits

Replacing the air filter at the same time as the lamp is straightforward and helps maintain cooling efficiency. The manufacturer highlights that a clogged filter reduces fan effectiveness and causes internal heat buildup. This combined approach protects optical components and supports consistent projector operation.

Filter Replacement Intervals

Manufacturers suggest cleaning the filter every three months and replacing it when changing the lamp. Some projectors display a warning icon when the filter needs attention, while others require visual inspection for dust buildup. Ignoring these intervals can shorten both lamp and projector lifespan.
