Author Topic: Small Edison LED bulbs: do they exist?  (Read 322 times)

For a Steampunk Rolling Ball Sculpture I'm working on, I'm looking for a decorative tiny light bulb. Approximately 1 or 1,5 inch. I like the style of Edison bulbs, but I can't seem to find any smaller than a regular sized bulb. LED filament could also work, although I'm afraid the light intensity will be too strong. I prefer LED because I'm running my system on a 5V power source.

Does anyone know about the existence of these kind of bulbs?
As a backup plan, I was thinking about replacing the interior of a refrigerator light with a (flickering) fake wax candle LED.

There are plenty of smaller LED filament bulbs now in America, thanks to General Electric swallowing up the competition (eg Feit Electric Co.).

Unfortunately, filament bulbs are pre-assembled with resistors for 120 V. So basically you'd need to break apart one bulb (which makes no sense for your project)

One option would be to take a basic DC filament automotive bulb and run it under voltage to get a lower light intensity. e.g. run a 12v bulb on 9v or even 6v.

Thanks for your replies. I think I'm gonna go with a DC filament bulb and test it out on different voltages. I'd be cool to make it glow at different intensities, might try using a PWM signal from my microcontroller to achieve that.

Is the system battery or mains powered? If you are connected to a transformer it won't matter that you're using small incandescent bulbs
