Ushio 1000026 BBA Projector Lamp

The Ushio 1000026 BBA is a 250W incandescent projector bulb with an A21 form factor. It operates on 115/125V input and produces 8500 lumens at a colour temperature of 3400K. The lamp is rated for a service life of 3 hours. It is intended for photographic and projection equipment.

Suited for photography and projection only

This bulb is designed specifically for photo flood and projector applications. It is not suitable for general home lighting fixtures. Buyers needing a long-life lamp for daily illumination should look at other options. The short rated life makes it impractical for continuous or residential use.

3-hour rated life decides fit

The 3-hour life rating is the critical specification that determines whether this lamp matches your workflow. If your projector or photographic session requires longer continuous operation without replacement, this model will not meet that need. Verify the expected usage time against this figure before purchasing.

Questions about this item

What voltage range does the 115/125V rating cover for this 250W bulb?

The lamp operates on a 115 to 125 volt supply, matching standard North American mains voltage for projector and photo-flood fixtures.

Which base and envelope size must the fixture accept for the A21 bulb?

The bulb uses a medium screw base and an A21 envelope, so the socket and housing must accommodate that standard diameter and length.

How is the incandescent lamp installed, and what common mistake shortens its 3-hour life?

Screw the bulb into a cool, powered-off fixture; avoid touching the glass with bare fingers, as oil residue creates hot spots that cause premature failure.
