Miniature LED Bulb Kit

The SIEMENS 52AEDB T3 1/4 is a miniature LED light bulb designed for indicator and panel applications. It operates at 24 volts and draws 15mA of current. The bulb uses a BA9s miniature bayonet base for a secure push-in connection. It is suited for users needing a direct replacement in compatible fixtures.

Voltage and Current Limits

This bulb is rated strictly for 24-volt circuits and a 15mA draw. Supplying a higher voltage will likely cause immediate failure. The low current means it cannot serve as a general illumination source. Builders must verify their panel voltage matches this rating before installation.

Build and Daily Use

The bulb body uses HAWA material and weighs 0.01 units. The BA9s bayonet base locks in with a push-and-twist action that resists vibration. An average life of 25,000 hours reduces the frequency of replacements in hard-to-reach panels. The white light colour provides clear status indication.

Questions about this item

Should I pick the 24 V miniature bayonet version or another voltage?

The kit uses a BA9s base and runs on 24 V, so choose this version only if your fixture supplies 24 V and accepts a miniature bayonet lamp.

What does the 15 mA draw mean for my push-button panel?

Each bulb draws 15 mA at 24 V, so a typical panel with several indicators will add only a few tens of milliamps to the control-circuit load.

Does the BA9s base limit the voltage or current I can use?

The BA9s base is rated for the bulb's 24 V, 15 mA design; exceeding either value risks overheating the miniature lamp and shortening its 25 000-hour life.
