Genuine 210 W UHP replacement lamp module rated for 4000 hours normal or 5000 hours economy use
The VS15948 module ships as a fully assembled 210W UHP bulb inside its housing, matching the original RLC-098 specification. It is intended for owners of compatible ViewSonic projectors who need a direct, new replacement without sourcing separate components.
Normal operation is rated at 4000 hours, while the economy setting extends the estimate to 5000 hours at reduced brightness. The 210W power draw is fixed by the lamp design, so any projector must supply that wattage and the correct ignition voltage for reliable starts.
Installation typically requires opening the projector's lamp door, releasing a retaining latch, and sliding the module into place until it seats firmly. The most frequent issues are forgetting to reset the hour counter in the menu, leaving dust on the lens or filter, and not tightening the door screws enough to satisfy the safety interlock.

The OEM version uses the original Philips 210W bulb; the OEM compatible comes from a different OEM bulb maker; the third-party compatible uses genuine OEM parts at a lower cost. All meet ISO9001 quality checks for beam performance, ignition, voltage and run-time.
The 210W Philips UHP bulb delivers the light output the projector was designed for; expect the same lumen level as the original lamp and similar heat, so the projector's existing cooling handles it without modification.
In normal mode the lamp lasts about 4,000 hours; switching to economy mode extends life to roughly 5,000 hours by reducing power and brightness, which also lowers fan noise and heat.
