Genuine ViewSonic PJ556 Replacement Lamp

The ViewSonic PJ556 projector lamp module delivers a new 280W UHP bulb pre-assembled in its housing for immediate installation. It fits ViewSonic projectors requiring the VLT-XD470LP part number and restores original brightness without additional tools.

Thermal and Power Profile

The 280W UHP lamp operates at its rated wattage during normal projection and shifts to a lower-power economy mode to reduce heat and fan noise. Rated life reaches 2,000 hours in normal mode and extends to 3,000 hours when economy mode is used consistently.

Deciding Specification — Lamp Life

Choose this module if your projector needs a 280W UHP lamp rated for 2,000 normal hours or 3,000 economy hours. Buyers who require a different wattage, a longer rated lifespan, or a bare bulb without housing should look elsewhere.

Questions about this item

How do I install the VLT-XD470LP lamp module and what step is often missed?

Remove the projector's lamp cover, loosen the securing screws, slide out the old module, insert the new 280W housing until it seats firmly, retighten the screws, replace the cover, then reset the lamp timer in the menu so the 2,000-hour normal or 3,000-hour economy counter starts from zero.

What maintenance or replacement will the PJ556 lamp need later?

The UHP 280W bulb is rated for 2,000 hours in normal mode or 3,000 hours in economy mode; once that limit is reached the lamp must be replaced with a new VLT-XD470LP module, as the bulb cannot be serviced separately.

What limit appears first during sustained use of this 280W lamp?

The rated lamp life of 2,000 hours in normal mode or 3,000 hours in economy mode is the primary limit; after those hours brightness drops and the projector will indicate that a replacement is required.
