Genuine 330 W AL lamp module

The Hitachi DT01291-A is a new aftermarket lamp-and-housing assembly built around a 330 W genuine AL series bulb. It is designed as a direct replacement for projectors that specify the DT01291 part code. Home-cinema owners and classroom technicians can swap the module without tools, restoring original brightness in minutes.

Thermal and power profile

The 330 W bulb draws its rated power once the projector reaches steady state, and the housing is engineered to match the original equipment cooling path. Fan noise and exhaust temperature remain consistent with the projector’s factory behaviour during typical viewing sessions. No additional power infrastructure is required beyond the projector’s own supply.

Sustained-load behaviour

Under continuous operation the lamp maintains stable output for the duration of its rated service life, with the 90 day warranty covering early failures. Brightness decay follows the normal curve for 330 W AL bulbs rather than exhibiting premature drop-off. The module is not intended for users who need field-replaceable bare bulbs or a longer manufacturer warranty period.

Questions about this item

How do I install the DT01291-A lamp and housing, and what step do people often miss?

Power off and unplug the projector, let it cool completely, remove the lamp cover, unscrew the old module, insert the new DT01291-A housing, secure the screws, replace the cover, then reset the lamp timer in the menu so the projector tracks the new 330W bulb correctly.

What maintenance or replacement will the DT01291-A need later?

The 330W AL Series bulb will dim over time; when brightness drops or the projector signals end of life, replace the entire lamp and housing module again — no separate filter or bulb-only service is specified for this unit.

What limit appears first during sustained use of the DT01291-A?

The 330W lamp generates significant heat; thermal protection will shut the projector down if ventilation is blocked or ambient temperature is too high, so keep intake and exhaust vents clear during long sessions.
