Ready-to-install lamp module

The Hitachi DT00591 is a complete projector lamp module that includes a new Ushio UHB 275W bulb already mounted in its housing. It is designed as a direct replacement for compatible Hitachi projectors and arrives ready for immediate installation without additional assembly. Buyers who need a bare bulb without the housing will not find that option here.

Sustained output over rated life

The lamp is rated for 2,000 hours of operation at its specified 275W power draw, giving a consistent brightness level throughout the rated lifespan rather than a short initial peak. Each unit undergoes quality checks for ignition stability, voltage regulation and run-time performance before it ships. Users who require a longer service interval than 2,000 hours should consider projectors that accept higher-capacity lamps.

UHB technology and ISO 9001 manufacturing

The UHB bulb operates within the electrical and optical parameters defined for this projector model, and the module is built to ISO 9001 production standards with checks covering beam performance, appearance and connections. The lamp is available in several OEM and compatible versions, all verified for the same fit and function. Installations that demand a different wattage or bulb technology cannot use this module.

Questions about this item

How much heat and power does the 275W UHB lamp produce during extended use?

The lamp draws 275 watts, so it generates significant heat; the projector’s internal cooling system must run continuously to keep temperatures stable during all-day operation.

Which Hitachi projectors accept the DT00591 lamp module without extra parts?

The DT00591 is a direct-fit replacement for the specific Hitachi models it was designed for; no additional cables, mounts or adapters are required beyond the projector itself.

Will the 2,000-hour lamp life still be reached if I keep using my older Hitachi projector daily?

Yes — provided the projector’s cooling fans and power supply are functioning correctly, the lamp is rated for 2,000 hours regardless of the projector’s age.
