I use both 3watt and 6watt bulbs (easily available) with a miniature base for various applications. Not aware that there is a 1watt sort in existance.
Here is a picture of my unit. What kind of bulbs are these? See how I clipped one of the 4 lights out, and replaced the spot with a piece of copper wire.
I believe the power wire comes off my doorbell transformer and is maybe 12-volts.
When I set my multi-meter to ACV-50, then touch the two screws, the needle moves across about 1/3 of the way. I do not know how to read this.
Any tips for a DIY fix?
