Ready-to-install 280 W projector lamp module

The Optoma DE.5811116085-SOT replacement lamp ships as a complete bulb-and-housing assembly, so technicians can swap it without handling a bare burner. It is intended for service teams and venue operators who need a direct drop-in part to restore brightness quickly.

OEM-grade Osram P-VIP bulb in a certified housing

Each unit uses a new Osram P-VIP 280 W bulb mounted in a factory-assembled housing that meets ISO 9001 production standards. The fixed connector layout and pre-aligned reflector eliminate alignment steps and reduce the risk of ignition failure during change-over.

Rated 2 000 hours normal or 3 000 hours economy mode

Lamp life is specified at 2 000 hours in normal operation and 3 000 hours when the projector runs in economy mode. Users planning continuous daily projection should schedule replacements around these limits, as output will decline beyond the rated intervals.
