Panasonic PT-DZ870LK 420W Replacement Lamp

This 420-watt lamp module serves as a direct replacement for the Panasonic PT-DZ870LK projector. It arrives as a fully assembled bulb and housing unit, enabling straightforward installation without additional assembly. The unit suits venue operators, educators and home-cinema owners who need to restore original brightness quickly.

Sustained Output Through Rated Life

The Osram UHM dual-s bulb is designed to maintain consistent light output across its rated 3,000-hour lifespan rather than fading rapidly after an initial peak. ISO9001 manufacturing controls verify beam performance, ignition reliability and run-time stability so the projector delivers steady illumination during long presentations or screenings.

Thermal and Power Profile

At 420 watts the lamp draws a fixed power level that the projector’s cooling system is engineered to manage, keeping internal temperatures within design limits. The genuine bulb construction supports stable voltage regulation, which helps contain fan noise and prevents the thermal cycling that can shorten component life.

Questions about this item

Does the 420W lamp run hot or noisy during long daily use?

The 420W Osram UHM bulb is designed for stable output over 3,000 hours; heat and fan noise depend on the projector's own cooling system.

Is the ET-LAD120W housing included so I can install it straight away?

Yes, the module arrives fully assembled with bulb and housing matched to the PT-DZ870LK, ready for tool-free replacement.

Will this lamp work in an older Panasonic projector that used a lower-wattage module?

It is built specifically for the PT-DZ870LK series; using it in a different model may cause ignition or fitment issues.
