Advanced Lamps CP-S840 Replacement Lamp

This replacement lamp and housing assembly is designed specifically for the Hitachi CP-S840 projector. It provides a new aftermarket light source to restore brightness when the original module reaches end of life. The unit arrives ready for installation without additional tools.

Guaranteed compatibility with CP-S840

The module is engineered to match the optical and electrical requirements of the specified projector model. A 90 day warranty covers the lamp against premature failure during initial operation. No software or firmware updates are required after fitting the replacement.

Practical limits of DLP lamp technology

Light output declines gradually over the operating hours of any projector lamp. Colour accuracy and contrast may shift as the bulb ages beyond its rated lifespan. Replacement restores initial performance but does not alter the native resolution or processing capabilities of the CP-S840 projector itself.

The lamp and housing weigh 0.9900 kg and fit the Hitachi CP-S840; heat output and fan noise are determined by the projector's cooling system, not the lamp alone.
