HITACHI DT01911-A DLP Replacement Lamp

Genuine AL DT01911 lamp module

The DT01911-A is a new aftermarket lamp and housing assembly built for Hitachi DLP projectors. It uses a genuine AL-series bulb inside a ready-to-install cage so the unit can be swapped without separate lamp handling. Home-cinema owners and classroom technicians who need a direct replacement for a dim or expired original will find the correct fit.

Check projector model and lamp code

Verify that the projector’s service menu or label lists DT01911 as the lamp part number before ordering. Confirm the existing housing matches the cage style shown in the product images to ensure mechanical alignment. The module is sold new with a 90 day warranty, so retain proof of purchase in case an early failure occurs.

Steady output through a full presentation

The AL-series bulb maintains consistent brightness across long meeting or movie sessions rather than fading after a short warm-up period. Operating temperature stabilises within the projector’s normal cooling cycle, so colour balance and light output remain even during extended use.

Replacement cycle and disposal

Plan to replace the module again when the projector’s lamp-hour counter reaches its rated limit or when image dimming becomes noticeable. The used unit contains a high-pressure bulb that should be recycled according to local electronic-waste guidelines rather than discarded in general waste.
