Ready-to-install projector lamp module

The OPTOMA TX774 OEM replacement lamp arrives as a fully assembled 280 W bulb and housing unit. It is designed for owners of compatible Optoma projectors who need a direct, new module without separate bulb handling. Installation is straightforward because the lamp ships pre-mounted in its housing.

ISO9001 manufacturing and OEM sourcing

Each unit is produced under ISO9001 quality controls and sourced from original bulb manufacturers such as Osram, Philips, Ushio, Phoenix, Iwasaki or Matsushita. The module matches the projector’s original electrical and mechanical interfaces, so it seats correctly and communicates with the projector’s lamp timer. No adapter or firmware step is required.

280 W UHP lamp rated for 2,000 hours

The 280 W ultra-high-pressure lamp delivers the brightness the projector was engineered for over a rated 2,000-hour service life. Power draw remains at the specified 280 W during normal operation. The projector’s built-in cooling system manages the thermal load, and the lamp’s ignition voltage stays within the original design limits.
