Ready-to-install replacement lamp

This Optoma 5811118924-SOT module ships as a complete assembly with a new Osram P-VIP 280W bulb seated in its housing, so the projector can be returned to service without handling the bare lamp. It is intended for owners of compatible Optoma projectors who need a direct OEM-specification replacement. Buyers who require a bare bulb without the housing or a lower-cost third-party alternative should look elsewhere.

Thermal behaviour and power draw

The lamp operates at its rated 280W and is designed to meet the projector's original thermal and acoustic profile when the unit's built-in cooling system is clean and functioning. Normal-mode runtime is rated at 3000 hours and Economy mode extends that to 4000 hours. ISO9001 manufacturing checks cover ignition voltage and beam performance to keep operating characteristics consistent.

Sustained-load characteristics

Under continuous operation the lamp maintains its specified output for the rated 3000-hour normal or 4000-hour economy life, provided the projector's filters and fans are maintained. Quality screening includes run-time verification so that brightness and colour stability hold through extended sessions rather than fading after a short burst.

Questions about this item

How is the Optoma 5811118924-SOT lamp module installed and what step do people often miss?

The unit ships as a complete housing with the 280W Osram P-VIP bulb already fitted, so you only need to remove the old module, insert the new one and secure the retaining screws; the step users forget is resetting the projector's lamp-hour counter after installation.

What maintenance or replacement will this 280W lamp need later?

The lamp itself is the consumable — rated for 3000 hours in normal mode or 4000 hours in economy mode — so once those hours are reached you simply replace the entire module again; no separate filter or bulb-only change is required.

What limit appears first during sustained use of this 280W projector lamp?

The rated lamp life of 3000 hours in normal mode or 4000 hours in economy mode is the first hard limit; after that the bulb's output drops below usable levels and the module must be swapped.
