Review on 💡 Efficient BA15D Bayonet Base Light: Optimal Volts for Exceptional Illumination by Amber Westbrooks

I bought these bulbs for a 1940's Singer 201-1 that my mother got as a graduation present. (Mom gave the machine to my wife a few years ago when she couldn't sew anymore.) I opted for the "cold" (white to almost blue) 6000K light over the warm or brown 3000K bulb. The main reason I chose these bulbs is the higher light output of 500 lumens instead of the 300 lumens typical of most of these replacement LED bulbs. I am very happy. Lamps give bright white light. The beauty is that LED bulbs emit far less heat than older incandescent bulbs; Lightbulbs will burn you if you accidentally touch them. I am very happy with these pears. The lamp was easy to assemble and fits perfectly. Since LED bulbs have a VERY long lifespan (Revain's listing says these bulbs should last 30,000 hours) I don't know what to do with 4 bulbs, but I think my great-great-grandchildren might need them in 100 years. if the sewing machine is still nearby :^)
