Ready-to-install replacement lamp

This 185W Dell 317-2531 module ships as a complete bulb-and-housing assembly, so no separate alignment or handling of a bare lamp is required. It is manufactured to ISO9001 quality standards and uses a genuine Philips UHP bulb. The unit is designed for direct fit in compatible Dell projectors.

Suited for owners of supported Dell models

The lamp delivers 3000 hours in normal mode and 4000 hours in economy mode, matching the original specification for brightness and runtime. Buyers who need a different wattage, a bare bulb without housing, or a lamp for a non-Dell projector should look elsewhere.

Pre-assembled housing speeds up maintenance

Because the bulb comes factory-mounted in its cage, installation time is reduced and the risk of contaminating the optical surface is minimised. The package contains only the lamp module itself; no tools, cables or software are included.

Questions about this item

Which Dell projector models accept the 317-2531 lamp module?

The 317-2531 module fits the Dell projectors that list this part number in their service manual; check your projector documentation to confirm compatibility before ordering.

Can I mix this 185W UHP lamp with an older lamp of different wattage in a dual-lamp projector?

Dual-lamp projectors require matched lamps of the same wattage and type, so replace both modules at the same time to maintain colour balance and avoid premature shutdown.

How do I verify the lamp is operating in economy mode for the 4,000-hour rating?

After installation, open the projector menu, select economy or low-power mode, and confirm the lamp-hour counter increments normally during use.
