Ushio 1000302 Halogen Projector Lamp

The Ushio 1000302 EJV JCR21V-150W is a 150-watt halogen reflector bulb designed for projector equipment. It produces a 3400K colour temperature suitable for presentation and display applications. The lamp is supplied new and carries the manufacturer part number 1000302.

Replaces EJV-coded reflector lamps in compatible

This bulb serves as a direct replacement for existing EJV-type halogen lamps rated at 150 watts and 21 volts. The upgrade is worthwhile when the original lamp reaches its rated 40-hour service life or when light output has visibly diminished. Users should verify the EJV designation and voltage before installation.

Delivers 150 watts for up to 40 hours of operation

At full power the lamp provides bright illumination for projection over its 40-hour rated lifetime. Headroom is limited by the short rated life; extended daily use will require frequent replacements. The 3400K output remains consistent until the filament reaches end of life.

Questions about this item

What voltage does the 21 V halogen bulb require for the projector socket?

The EJV JCR21V-150W is rated for 21 volts and 150 watts; match the projector's voltage exactly to avoid premature failure.

How do I seat the reflector halogen without contaminating the quartz envelope?

Handle the bulb with clean gloves or a lint-free cloth, align the base pins with the socket, and press firmly until seated; oils from skin create hot spots that shorten the 40-hour life.

When should I replace the 3400 K lamp after 40 hours of use?

Plan replacement once the projector reaches 40 cumulative hours; colour output shifts and intensity drops noticeably beyond the rated lifetime.
