Two-lamp kit for Hitachi projectors

This twin pack supplies two replacement lamps built for the Hitachi HCP-6600X and compatible models including the CPX605. Each unit matches OEM part numbers DT00771, 456-8943, 78-6969-9893-5 and RLC-021. Home-theatre owners and classroom technicians can keep a spare on hand to avoid downtime during presentations or movie nights.

Thermals noise and power in normal use

The lamps operate at the same voltage and wattage as the original modules, so the projector’s existing cooling system handles heat without extra fan speed. Acoustic output stays at the level the manufacturer designed for the HCP-6600X chassis. Power draw remains identical to the factory specification, leaving the unit’s electrical safety margins unchanged.

Questions about this item

How do I install the DT00771 lamp module in my Hitachi projector, and what step is often missed?

Power down the projector, unplug it, and let it cool completely; remove the lamp cover, release the retaining screws, slide out the old module, insert the new DT00771 unit until it seats firmly, replace screws and cover, then reset the lamp timer in the menu — skipping the timer reset is the step most users forget.

When will the CPX605LAMP need replacement, and what maintenance does it require?

The lamp is rated for typical projector hours; replace it when brightness drops noticeably or the projector signals end of life — no user maintenance is needed beyond keeping the air filters clean so the lamp runs at proper temperature.
