I've recently discovered (under a ceiling that I took off) and old wall-mounted lamp. It has a curious lightbulb which I failed to identify so far. The lightbulb works right now (gives a beautiful "retro" glow), but should it ever die, I'd like to know if there's an option for a replacement. The issue is that the bulb is very short - around 15 mm - to fit the small housing of the lamp.

The lightbulb is 5W, has an E27 thread. Location is Netherlands (230 V).

I would appreciate help with identifying this lightbulb - or information on similar bulb types that would fit the housing - so that I can search for replacement options.

  • Check bulbs made for ovens - often short etc

  • @SolarMike But ovens mostly have E14 threads, AFAIK.

  • That retro thing is a genuine incandescent bulb, which makes light by making heat. Basically it's an electric campfire. It won't last long; it should go to the lightbulb museum while it still can! Sep 28, 2020 at 15:39
  • Quite a bit longer and probably brighter but these are at least LED. Oct 1, 2020 at 5:16

The nearest I can find in size and wattage is a Bulbrite Industries, Inc. E26/E27 7.5 watt "25G12/CL-220" at this website:

https://bulbman.com/globe/3391-25g12-cl-220.html (I don't know anything about bulbman.com)

It looks like a 220v decorative bulb. I have not been able to find a direct replacement.

Based upon the filament supports, it looks like a very long-lasting bulb design. If the bulb is rated for 230v and is being used in a 220v environment, it will last roughly twice as long as its rating.

If the color doesn't matter, you could use a 7.5 watt S11 sign light bulb with an E26 base. Unknown availability in EU.

Or you could go with any number of LED replacements.

This was a challenge to find a relatively close match in the US.
