EDWARDS-SIGNALING 2705W120V Miniature Incandescent Light Bulb light kit

Miniature Incandescent Bulb

This Edwards Signaling 2705W120V bulb fits fixtures requiring a double contact bayonet base and 120V AC supply. It delivers 5 watts of white incandescent light for indicator or low-level illumination tasks. The unit is CE certified and cULus listed for compliance. Buyers needing LED efficiency or dimmable operation should choose a different technology.

Replaces 5 W BA15d Lamps

It serves as a direct swap for existing T3-1/4 incandescent bulbs with the same base and voltage. The jump is worth it when the old lamp has reached its 2,500 hour rated life or shows filament failure. No circuitry changes are required because the electrical characteristics match the original specification. Keep a spare on hand for critical signalling circuits.

Simple Bayonet Installation

Push the bulb into the BA15d socket and twist to lock the double contacts in place. The miniature T3-1/4 envelope fits tight panels without forcing. The most common issue is inserting the bulb at an angle which bends the base pins and prevents full contact. Verify the fixture is de-energised before replacement to avoid a 120V shock hazard.
