That’s a nice find. I’d kinda like to try a couple and see how they work.
The description for both the 6v and 12v versions offer a disclaimer. Sounds like the dimmable range with a rheostat dimmer might be pretty narrow. Not sure that I really care, as long as the light isn’t blindingly bright.
Let us know.
That is generally the biggest problem with this kind of inexpensive led replacements. They just use a current limiting resistor, so the input voltage change between dazzling bright and off tends to be very, very small.
Edit: this is a generalization of cheap led replacement bulbs as a whole, not this specific model. It would be somewhat interesting to know if this model has that issue or not. Having an extremely wide voltage range would be a mark in its favor of potentially working better.
