Knoll HD225 OEM Replacement Lamp 170W

The Knoll HD225 is a complete projector lamp module built around a new Philips UHP 170W bulb. It arrives pre-assembled in its housing so the installer can swap it in without handling the bare lamp. This unit is intended for owners of Knoll projectors that specify the HD225 lamp code and who want a direct OEM-standard replacement.

Fits Knoll HD225 projectors with no extra parts

Because the bulb and housing ship as one piece, the module fits the projector’s existing lamp cage and connector without adapters or tools. The 170W UHP lamp draws the same power as the original, so the projector’s power supply and cooling system remain unchanged. Installation frees the user from aligning a bare bulb or reusing an old housing, reducing the risk of misalignment or dust contamination.

Replaces a spent or dimming HD225 lamp module

When the original lamp reaches its 2000-hour rated life or shows reduced brightness, this module restores the projector’s output to factory levels. The jump is worth it if the image has become noticeably dimmer, colour fidelity has drifted, or the projector warns that lamp replacement is due. It is not suited for users who need a higher-wattage lamp, a different lamp code, or a bare bulb for a custom housing.
