Direct replacement for Viewsonic PX729-4KS
This new aftermarket lamp and housing assembly is built for the Viewsonic PX729-4KS projector. It restores original brightness when the installed lamp reaches end of life. Home-theater owners and installers can swap it without tools. The module ships ready to install.
90-day warranty covers early failure
The unit carries a 90-day warranty against defects. Normal operation follows the projector’s own thermal and power management. No separate fan or cooling requirement is added by this lamp. Power draw matches the original specification.
Upgrades a dimming or expired original lamp
Replaces the factory lamp when image brightness drops or the projector signals replacement. The jump is worth it when the current lamp no longer delivers a watchable picture. Buyers needing a different projector model or a bare bulb without housing should look elsewhere.

Questions about this item
How do I install the lamp & housing in my Viewsonic PX729-4KS projector without resetting the lamp timer too early?
Power off and unplug the projector, let it cool completely, remove the lamp cover, unscrew the old module, insert the new PX729-4KS-LAMP-A housing, secure the screws, replace the cover, then reset the lamp timer in the projector menu only after the new lamp strikes.
What maintenance will this AL Series lamp & housing need later?
Clean the projector air filters every few months to prevent overheating; the lamp itself is a sealed module with no user-serviceable parts, so replacement is the only action when brightness drops or the projector indicates end of life.
What limit appears first during long viewing sessions with this replacement lamp?
Thermal protection is the first limit — if internal temperatures rise above safe levels the projector will dim or shut down to protect the AL Series lamp and optical engine.
