Genuine Vivitek DX831 replacement lamp

The Vivitek DX831-LAMP is a new projector lamp module supplied as a fully assembled 310 W bulb and housing. It matches the original part number 5811120589-S and is manufactured to ISO 9001 quality standards. The unit weighs 0.9990 kg and is ready for direct installation in compatible Vivitek projectors.

Replaces a spent original lamp

When the factory lamp reaches its 2 500-hour rated life, this module restores full brightness without requiring separate bulb handling. The jump is worth it when the projector dims, shows a lamp warning, or fails to strike. It is not for users who need a higher-wattage alternative or a different form factor than the DX831 specification.

Fits DX831-compatible projectors

The assembled housing slots into the existing lamp bay, freeing the installer from aligning a bare bulb. No extra tools or adapters are described in the data. Buyers who need a lamp for a non-DX831 model or a different wattage should verify their projector's exact part number before ordering.

Questions about this item

Will the 310W module fit the DX831 projector housing without modification?

The lamp is a fully assembled bulb and housing built to the DX831 form factor, so it seats directly in the projector's lamp bay.

Which step do installers most often skip when fitting the 5811120589-S module?

After sliding the unit in, the retaining screws must be tightened and the lamp-hour counter reset through the projector menu, otherwise the replacement warning stays on.

When should the 2500-hour lamp be swapped out again?

Plan a replacement once the on-screen timer approaches 2,500 hours or when brightness drops noticeably, whichever comes first.
