Ready-to-install lamp module

The Hitachi CP-AX2503 lamp module ships as a complete assembly with a new Philips UHP 225W bulb already seated in its housing, so it fits straight into compatible Hitachi projectors without extra steps. It is intended for users who need a direct replacement for the original DT01511 lamp.

Lamp life and operating modes

In normal mode the lamp is rated for 4,500 hours of use, while economy mode extends the rating to 6,000 hours; actual runtime will vary with usage patterns, ambient temperature and projector ventilation. The 225W UHP light source defines the brightness and power draw, so the projector must be designed for that wattage.

Simple swap with common pitfalls

Installation typically requires opening the projector lamp door, removing the old module and sliding the new one in until it seats firmly; the process takes a few minutes with basic hand tools. Common issues include forgetting to reset the projector lamp timer after replacement, leaving dust on the lens or housing vents, and not securing the lamp cover latch, which can prevent the projector from powering on.

Questions about this item

Which version of the CP-AX2503 lamp should I choose among the OEM and compatible options?

Three OEM versions are offered: the original bulb manufacturer's lamp, the same lamp sold by Hitachi, and an OEM-compatible version from a different bulb maker. An economical compatible version using genuine OEM parts is also available.

What does the 225W rating mean for brightness and heat in my projector?

The 225W UHP bulb delivers the light output the CP-AX2503 was designed for, so image brightness matches the original specification and the projector's cooling system handles the heat as intended.

How do the 4,500-hour normal and 6,000-hour economy ratings translate to real use?

In normal mode expect about 4,500 hours of operation; switching to economy mode extends usable life to roughly 6,000 hours by reducing lamp power and brightness.
