Replacement lamp for CP-EX400N projectors

This genuine Hitachi replacement lamp fits the CP-EX400N projector and contains an original OEM bulb inside a compatible housing. It is intended for owners who need to restore factory brightness after the original lamp reaches end of life. Buyers whose projector uses a different lamp module cannot use this unit.

Runs at spec with OEM bulb

The lamp operates at the manufacturer's specified power draw and thermal profile because the bulb is the same OEM component used in the original assembly. Normal use delivers the expected brightness and colour accuracy without added noise or heat beyond the projector's standard design. The 180 day warranty covers defects in materials or workmanship.

Consistent output over full service life

Under sustained operation the OEM bulb maintains stable light output and colour fidelity for the rated service interval rather than fading early as some generic alternatives do. The housing is built to match the projector's cooling and alignment requirements so performance remains steady during long presentations or film sessions. No compatibility with other projector models is implied.

Questions about this item

How do I install the Hitachi CP-EX400N lamp housing and which step is most often missed?

Power off and unplug the projector, let it cool completely, remove the lamp cover, unscrew the old module, insert the new housing until it seats firmly, replace the screws, reattach the cover, then reset the lamp timer in the menu — skipping the timer reset is the step most people forget.

What maintenance or replacement will this lamp need later?

The genuine OEM bulb inside is rated for its full service life; when brightness drops or the projector signals end of life, replace the entire lamp housing again — no separate bulb swap or filter cleaning is required for this module.

What limit appears first during extended use of the CP-EX400N lamp?

The 180‑day warranty period marks the covered defect window; beyond that, gradual lumen depreciation and eventual bulb end‑of‑life are the natural limits that determine when a new housing is needed.
