Eaton 28-5185 2.2 W BA9s Bulb

The Eaton 28-5185 is a 2.2 W incandescent bulb with a T3-1/4 shape and BA9s miniature bayonet base. It operates on 24 V AC and produces 4 lumens of white light with a rated life of 15,000 hours. The bulb measures 1 3/16 in overall length and carries CE and CSA certifications.

Suited for 24 V indicator panels

This lamp fits panels and equipment requiring a BA9s base at 24 V AC where a low-output white indicator is specified. It is not dimmable, so circuits needing brightness control should look elsewhere. Buyers needing higher lumen output or a different voltage will need a different bulb.

No bundled accessories included

The product is supplied as a single bulb without additional hardware, connectors or software. Installation relies solely on the BA9s base mating with the matching socket. Certifications confirm compliance with CE and CSA standards for the component itself.

Questions about this item

Does the fixture already need a BA9s miniature bayonet socket for this 24 V 2.2 W bulb?

Yes, the bulb uses a BA9s miniature bayonet base, so the fixture must provide that exact socket type.

Will this 24 V AC incandescent bulb operate correctly if the existing circuit is also 24 V AC?

The bulb is rated for 24 V AC, so it will work on a matching 24 V AC circuit without modification.

How can I confirm the bulb is performing as specified once installed?

At 24 V AC it should draw 2.2 W, produce 4 lm of white light, and reach its 15,000-hour rated life under normal conditions.
