Projector Lamp / Bulb for Hitachi, Dukane DT01481 / 456-8931WA

The module with housing includes the bulb pre-installed in a plastic cage, allowing for a quick, plug-and-play replacement. The bare bulb option requires you to remove the old bulb from your existing housing and install the new one, which is more cost-effective but requires a bit more technical effort.

This lamp is specifically engineered for Hitachi and Dukane models that utilize the DT01481 or 456-8931WA part numbers. Always check your projector's user manual or the label on your current lamp housing to confirm these specific part numbers match your device.

To get the full 6,000-hour lifespan, use your projector in 'Economy' or 'Eco' mode, which reduces the power consumption and heat generated by the bulb. Additionally, ensure your projector's air filters are cleaned regularly to prevent overheating, which is the primary cause of premature lamp failure.

Yes, this lamp is manufactured to ISO9001 standards to ensure it meets the brightness, color accuracy, and contrast specifications of your projector. While it is a compatible replacement rather than an OEM-branded part, it is designed to restore your projector to its original performance levels.

First, ensure the lamp housing is fully seated and the safety interlock switch is engaged, as most projectors will not power on if the lamp door is not securely closed. If it still fails to light, double-check the electrical connections and reset the projector's lamp timer in the settings menu.
