Review on 💡 Efficient BA15D Bayonet Base Light: Optimal Volts for Exceptional Illumination by James Notti

I bought this for my vintage Singer 201 sewing machine hoping it wouldn't take too long as some of the LEDs weren't working. They're actually the same length as incandescent bulbs, so they have plenty of room. The light is significantly brighter than incandescent and the daylight color is really good for sewing! They should fit any sewing machine (or other item) that is compatible with a standard bulb of this type. If I have any issues with the bulbs I'll update this review, but for now they're a solid five stars. Update: The lamp in my Singer 201 has had a lot of use and is holding up well so far. I just fitted a different bulb to my Singer 401A and it fits and works great. The brightness and color made my jelly roll rug much easier to sew! I've attached a picture of the built in. Update 2: I just received the 301A and installed another of these lamps. Fits/works great. All light bulbs still work perfectly. Update 3: I've tried it with my featherweight and it works great. Update 4: Also works great in Elna SU and Singer 401. I haven't found a machine that accepts this type of bulb yet, which hasn't worked.
