Dell 1210S Replacement Lamp Module

This Dell 1210S lamp module delivers a direct replacement for the Dell 1210S projector. It arrives as a fully assembled 185W UHP bulb inside its housing, ready for immediate installation. The unit is built to match the original equipment specifications for brightness and fit. It serves owners of the 1210S model who need a new light source.

Easy Housing Swap With No Alignment Steps

Installation requires only opening the projector lamp door, removing the old module and sliding the new housing into place until it seats. Because the bulb comes pre-mounted in the correct housing, there is no need to handle the bare lamp or adjust reflector alignment. The most common issue is forgetting to reset the projector lamp timer after fitting the module, which can leave the replacement warning active. A second pitfall is leaving dust on the lens or filter during the swap, which reduces image quality from the first use.

Rated Hours Define The Practical Limit

The lamp is rated for 3000 hours in normal mode and 4000 hours in economy mode, so actual service life depends on which brightness setting the projector runs. Running constantly at full power will reach the limit sooner than mixed or economy use. There is no user-serviceable component inside the sealed housing; once the rated hours are exceeded, brightness drops and the module must be replaced again. The 185W power draw also means the projector cooling system must handle that thermal load continuously.

Questions about this item

How do I confirm the 1210S lamp is running at the rated 185W after installation?

Check the projector menu for lamp power or wattage readout; it should display 185W. Also verify the hour counter starts from zero and the image reaches expected brightness without flicker.

What comes in the box with the 317-2531 lamp module, and is anything else required?

The module includes a new Philips UHP 185W bulb pre-assembled in its housing, ready to install. No extra parts or tools are needed for the swap.

Which version of the 1210S lamp should I choose among the OEM and compatible options?

Choose the OEM version from the original bulb manufacturer for exact factory performance, the Dell-sold OEM for brand-matched supply, another OEM brand for equivalent specs, or the compatible version for lower cost using genuine OEM parts.
