Ready-to-install 250 W replacement lamp

This Knoll Systems HD177 module ships with a new Philips UHP 250 W bulb already seated in its housing. It is built for owners of compatible Knoll projectors who need a drop-in replacement without extra assembly steps. The lamp is rated for 2,000 hours of typical use.

Replaces a dim or failed original lamp

Swap this unit in when the existing lamp reaches end of life, shows reduced brightness, or triggers a replacement warning. The jump is worth it when the projector is otherwise functioning and a full lamp module is preferred over bare-bulb handling. Four supply versions exist, all manufactured to ISO 9001 quality standards.

Confirm the exact projector model first

Knoll offers multiple HD177 lamp versions, including OEM, OEM-compatible and third-party compatible builds. Verify that your projector accepts the HD177 designation before ordering. No tools or additional parts are required for installation once the correct match is confirmed.

Questions about this item

Does the HD177 lamp module include the housing so it fits directly into the projector?

Yes, the HD177 module is supplied as a fully assembled bulb and housing, ready for direct installation in your Knoll projector.

What is the correct procedure for installing the HD177 lamp, and what common step is often missed?

Power off the projector and let it cool completely, then remove the old module, insert the new HD177 unit until it seats firmly, and finally reset the lamp-hour counter in the menu — skipping the reset is the step most often forgotten.

When will the HD177 lamp need replacement based on its rated life?

The lamp is rated for 2,000 hours of use; plan to replace it once the projector’s lamp-hour counter approaches that figure.
