Ready-to-install 280W lamp module

This Optoma DE.5811100908 replacement lamp arrives as a fully assembled bulb and housing, so it fits straight into compatible Optoma projectors without extra assembly. It is aimed at owners who need a direct swap to restore brightness and colour accuracy.

ISO9001 manufacturing and Osram UHP bulb

Each unit is built to ISO9001 quality standards and uses a genuine Osram UHP 280W bulb, with strict checks on beam performance, ignition, voltage, connections and run-time. The pre-mounted housing means no handling of a bare lamp, reducing the risk of contamination during installation.

2,000-hour rated life across OEM

The lamp is rated for 2,000 hours of operation, whether supplied as an original OEM module from Philips, Osram, Ushio, Phoenix, Iwasaki or Matsushita, or as a leading third-party compatible built with genuine OEM parts. Buyers who need a longer-rated lamp or a different wattage should look elsewhere.

Questions about this item

What wattage does the Optoma DE.5811100908 lamp draw and how does that affect brightness?

The lamp is rated at 280 W, which sets the light output the projector was designed for; running a different wattage would change brightness and could damage the optical engine.

Does the DE.5811100908 module include the housing so it fits directly into the projector?

Yes, the unit ships as a fully assembled bulb-and-housing module that matches the original form factor for a direct swap.

What is the correct way to install the DE.5811100908 lamp and what step do people often miss?

Power off and unplug the projector, let it cool completely, remove the old module, insert the new one until it seats firmly, then reset the lamp-hour counter in the menu — skipping the reset is the common mistake.
