Replacement Lamp for Hitachi Projectors

This module is a new 225W replacement lamp built for Hitachi projectors using the DT01481 part number. It arrives as a complete bulb-and-housing assembly so it can be fitted without extra tools. The lamp uses a Philips UHP bulb rated for 5000 hours in normal mode and 6000 hours in economy mode. It suits schools, offices and home users who need a direct swap for a dim or failed original lamp.

Build Quality and Installation

Each unit is manufactured to ISO 9001 standards and tested for beam performance, ignition, voltage, connections and run-time. The housing matches the original mounting points so the lamp seats securely in the projector’s lamp compartment. A pre-assembled connector plugs straight into the existing socket, eliminating wiring steps. The lamp is offered in OEM and compatible versions, all built from genuine Philips, Osram, Ushio, Phoenix, Iwasaki or Matsushita components.

Compatibility Check Before Ordering

Verify that your projector lists the DT01481 or 456-8931WA part number in its service manual or on the existing lamp label. Confirm the projector accepts a 225W UHP lamp; higher or lower wattage modules will not operate correctly. Ensure the lamp compartment is clean and the air filter is clear so the new lamp reaches its rated life. Buyers who need a different wattage or a bare bulb without housing should look for a module that matches those exact specifications.

Questions about this item

What lamp interface or connector does the 456-8931WA module use, and what wattage does it support?

The module is a complete lamp-and-housing assembly designed for Hitachi projectors that accept the 456-8931WA part; it ships with a Philips UHP 225W bulb that defines the power draw.

What physical space and mounting points does the DT01481 housing require inside the projector?

The pre-assembled housing matches the original Dukane 456-8931WA form factor, so it seats directly into the projector’s lamp bay using the existing screw holes and alignment tabs.

How is the lamp module installed, and what step do people often miss?

Power off and cool the projector, remove the lamp cover, release the retaining screws, slide the old module out, insert the new DT01481 unit until it clicks, re-tighten the screws, replace the cover, then reset the lamp-hour counter in the projector menu — the reset is the step most often forgotten.
