Direct replacement for Optoma HD81

This 300 W projector lamp module fits the Optoma HD81 model. It ships as a fully assembled bulb and housing so you can install it without extra tools or alignment steps. The unit is supplied new and ready for immediate use.

Lamp life and technology limits

The Philips UHP bulb is rated for 2,000 hours of operation. Brightness will gradually decline as the lamp ages and the projector will eventually indicate that a replacement is needed. The lamp contains mercury and must be recycled according to local regulations when it reaches end of life.

Compatibility check before ordering

Verify that your projector is the Optoma HD81 and that the original lamp part number matches SP.83C01G001. The listing covers several OEM and compatible versions; confirm which version your installation requires before placing the order.
