Questions about this item

How long before the 285W NSH bulb inside the PJ1158 module needs replacement?

The lamp module is rated for typical projector lifecycles; brightness will gradually diminish until a new 285W bulb is required.

What limits continuous operation of the 285W lamp in the PJ1158 housing?

The 285W power draw defines the thermal envelope; the projector's cooling system must dissipate that heat to maintain stable output.

How much fan noise and heat does the 285W PJ1158 lamp produce during all-day use?

At 285W the lamp generates significant heat, so the projector's fans run at speeds needed to keep the NSH bulb within safe temperatures.
