Hitachi DT01871 Replacement Lamp

This is a new Hitachi DT01871 projector lamp module supplied with a Philips UHP 370W bulb pre-fitted in its housing. It is intended for owners of compatible Hitachi projectors who need a direct replacement light source. The module arrives fully assembled so no separate bulb handling is required. Buyers who want a bare bulb without housing or who use a non-Hitachi projector cannot use this product.

Two Lamp Life Ratings

The lamp is rated for 2000 hours in standard mode and 4000 hours in economy mode, giving the user a choice between maximum brightness and extended operating time. Each unit is tested to ISO 9001 standards for beam performance, ignition, voltage, appearance, connections and run-time before shipment. No additional software or accessories are bundled with the lamp itself.

Tool-Free Module Swap

Because the bulb is already seated in the housing, installation consists of opening the projector lamp door, removing the old module and sliding the new one into place. The most common issue is forgetting to reset the projector's lamp-hour counter after fitting the new module, which leaves the replacement warning active. Ensure the projector is cool and unplugged before starting the swap.

Questions about this item

When will the 370 W UHP bulb need replacing in standard mode?

The lamp is rated for 2000 hours in standard mode and 4000 hours in economy mode before replacement is recommended.

What limits continuous operation first — heat or lamp life?

The 370 W UHP lamp reaches its rated 2000-hour standard-mode life before thermal limits become the primary constraint.

How much fan noise and heat does the 370 W module produce during all-day use?

The 370 W UHP lamp generates typical high-wattage projector heat and fan noise; economy mode reduces both by lowering power draw and extending life to 4000 hours.
