Sony LMP-E191 Bare Bulb Replacement

This genuine OEM Philips UHP bare bulb replaces the lamp in Sony LMP-E191 projectors. It delivers the correct ignition parameters and cooling match to maintain original brightness and colour accuracy. The unit ships without a cage assembly for installer fitting.

Power Range and Arc Constraints

The bulb operates within a 190W power range and uses a 1.0 mm arc length with an E19.4 reflector shape. These fixed specifications define the luminance output and thermal profile that the projector chassis must support. Deviations in driving mode or cooling can cause premature failure or image artefacts.

Projector Compatibility Check

Verify that your projector model is exactly Sony LMP-E191 before ordering. Confirm the existing housing accepts a bare Philips UHP 220-150W 1.0 E19.4 bulb and that you can reinstall the original cage assembly. This bulb is not suited for projectors requiring a different wattage, arc length or reflector geometry.

Questions about this item

Should I choose the 220 W or 150 W version of this Philips UHP bulb for my Sony LMP-E191 projector?

The bulb operates across a 220-150 W power range, with a 190 W typical rating, so a single part covers both settings.

What does the 190 W typical power figure mean for brightness and heat in my projector?

It indicates the nominal driving power the lamp expects; the projector's ballast will regulate output to match this level for stable luminance and thermal performance.

How does the E19.4 reflector shape and 1.0 mm arc length affect fit and ignition?

The E19.4 reflector and 1.0 mm arc are matched to the Sony LMP-E191 optical path and ignition parameters, ensuring correct focus, cooling alignment and reliable start-up.
