I have a number of lights which use up a lot of amps when lit, so I wanted to update the bulbs to LEDs.
The first set of bulbs didn’t work, so I swapped the wire polarity as I had read that can make a difference. No change.
I decided to try a different bulb and I’m glad I did as I had great success with these LEDs from Aten Lighting. No need to mess with polarity, they just worked.
