Miniature Incandescent Bulb

This Eaton miniature incandescent bulb uses a BA9s bayonet base and operates at 32 V AC. It draws 2 W and produces 4 lm of white light. The T3-1/4 envelope measures 30.5 mm overall length. It is CE and CSA certified.

Capacity and headroom

Rated at 3 000 hours, the filament suits indicator and panel-lighting duty where continuous operation is intermittent. Light output is low, so it cannot serve as general illumination or high-visibility signalling. Dimmable operation is not supported.

Practical limits of the standard

The BA9s base fits standard miniature bayonet sockets, but the 32 V rating restricts use to matching control-voltage circuits. Incandescent technology generates heat and offers limited efficacy compared with LED alternatives. No dimming or colour-temperature control is available.

Questions about this item

Will the 32 V incandescent bulb work with the older 28 V control panel I am keeping?

The bulb is rated for 32 V AC; running it on a 28 V panel will produce lower light output and may shorten the 3 000-hour rated life.

How can I confirm the 1828 miniature bayonet bulb is operating correctly after installation?

Apply 32 V AC and verify the bulb emits a white glow at roughly 4 lm; the filament should be visibly lit without flicker.

Does the package include a BA9s socket or only the T3-1/4 bulb itself?

Only the 1828 incandescent bulb is supplied; a compatible BA9s miniature bayonet socket must be purchased separately.
