Genuine Philips UHP bare bulb

This genuine Philips UHP bare bulb replaces the lamp in the Hitachi ED-X40 projector without requiring a cage assembly. It matches the original cooling setup and ignition parameters to prevent overheating, flickering and premature shattering. The bulb delivers the specified 210 W power range with a 0.8 mm arc and E19.4 reflector shape. Installers receive the exact OEM component specified for this projector model.

210 W power range and arc performance

The 210 W power range supports the projector's designed brightness and uniform light distribution for typical presentation and classroom use. At this wattage the 0.8 mm arc maintains stable ignition and consistent colour output throughout the rated lamp life. The bulb will not support projectors that require a different power range, arc length or reflector geometry. Users needing higher lumen output or a different form factor must select a lamp matched to those specifications.

Philips UHP technology limits

Philips UHP technology provides the highest luminance available for this projector platform, but brightness still decays gradually over the lamp's service life. The bare bulb format requires careful handling during installation to avoid contaminating the arc tube. Cooling and driving circuitry must remain within the original ED-X40 design limits or the bulb may suffer reduced life, colour shift or catastrophic failure. No adapter or converter can make this bulb compatible with other projector models.

Questions about this item

Will the 0.8 mm arc length work with the original cooling setup in my ED-X40 projector?

Yes, the bulb matches the required cooling setup and driving mode to prevent overheating, flickering, or premature lumen decay in the ED-X40.

How can I verify the Philips UHP bulb is performing correctly after installation?

Correct operation shows stable brightness without flickering, accurate colour reproduction, and no unexpected shutdowns from the projector's thermal protection.

Does this purchase include the cage assembly or only the 210-140W bare bulb?

Only the genuine OEM Philips UHP bare bulb is included; the cage assembly must be reused from the old lamp or purchased separately.
