Ready-to-install lamp module

The ViewSonic PJ551D-2 is a new 180W replacement projector lamp supplied as a fully assembled bulb and housing unit. It matches the original POA-LMP118 specification and fits directly into compatible ViewSonic projectors without additional assembly. This module is intended for owners who need a drop-in replacement when the original lamp reaches end of life.

Rated output and service interval

The UHP bulb operates at 180W and carries a rated lamp life of 2,000 hours under normal use. Each unit is produced to ISO9001 quality standards and tested for beam performance, ignition voltage, and run-time before shipping. The fixed wattage means power draw and thermal output remain consistent with the projector's original design envelope.

Consistent output over the full cycle

Because the lamp is built to the same 180W specification as the factory module, brightness and colour stability hold steady across the 2,000-hour rating rather than fading after a short burst. The assembled housing maintains correct alignment throughout the service interval, so the projector does not develop hot-spots or ignition issues as the bulb ages. Buyers who need a longer-rated lamp or a different wattage for another model will need a different part number.

Questions about this item

How do I install the PJ551D-2 lamp module and what step is often missed?

Power off and unplug the projector, let it cool completely, remove the lamp cover, unscrew and pull out the old module, insert the new POA-LMP118 housing until it seats firmly, replace and tighten the screws, refit the cover, then reset the lamp timer in the projector menu so the 2,000-hour counter starts from zero.

What maintenance or replacement will this 180W UHP lamp need later?

The lamp is rated for 2,000 hours of use; after that the bulb will dim and eventually fail, requiring a full module replacement — no user-serviceable parts inside the housing, and the air filters in the projector should be cleaned regularly to avoid overheating that shortens lamp life.

What limit appears first during sustained use of this 180W lamp?

The 2,000-hour rated lifespan is the primary limit; continuous operation accelerates brightness decay and raises internal temperature, so the lamp will reach end-of-life before any other component in the module fails.
