Miniature LED Bulb for Stacklight Applications

The Edwards-Signaling 270LEDR120V is a T3-1/4 miniature LED bulb designed for stacklight installations. It operates on 120V AC power and features a double contact bayonet BA15d base for secure fitting. The bulb emits a red light suitable for indoor or outdoor signalling needs. It is supplied in new condition for immediate deployment.

Thermals Noise and Power Characteristics

As an LED light source, the bulb generates minimal heat during standard operation compared to incandescent alternatives. It draws power directly from a 120V AC supply without requiring an external driver or transformer. The solid-state construction ensures silent performance with no audible hum or vibration. This makes it appropriate for environments where low thermal output and quiet running are required.

Shatter Resistant Rating and Usage Constraints

The bulb is not rated as shatter-resistant and carries no rough service certification for high-vibration locations. Buyers needing impact protection or ruggedised filaments should seek alternative models. The red light appearance has no rated colour temperature specification for precise chromaticity matching. Indoor and outdoor use is supported within standard socket enclosures.

Questions about this item

How do I install the 270LEDR120V bulb into a BA15d socket without damaging the pins?

Align the two offset pins on the double-contact bayonet base with the matching slots in the BA15d socket, push straight in, then twist clockwise until the pins lock under the retaining clips; forcing it sideways bends the pins and breaks the base.

What maintenance will this 120 V miniature LED bulb need over its service life?

No scheduled maintenance is required; the sealed LED package has no user-replaceable parts, so when light output finally drops below useful levels the entire bulb is replaced.

At what point does the 120 V AC supply become the limiting factor during continuous operation?

The bulb is rated for 120 V AC; sustained voltage above that level will overdrive the internal driver and cause premature failure before any thermal limit is reached.
