Lamsky BA15D LED Double Contact Bayonet Base Sewing Machine Bulb AC110-130V,T3/T4/C7/S6,4W Daylight 6000K,LED 40W Halogen Replacement Bulb,No-Dimmable,2-Pack

Great product, I have 5 vintage sewing machine , one Kenmore and the others are Singer in different models , the lights fitted in all of them, what a difference it made! The white bright light let me see clearly and there is no heat , actually I ordered a second set .

I bought this to see if it would work in my microscope upper light. It did not. The lens for the top light means that the led individual lights are concentrated, and the result is a very odd and not useful spread of the light. I look forward to the day that LED will work in this part of my microscope. I gave one star because it didnt work for my specific purpose. However, it was very bright, I liked the color, and it came well packaged. If you are using it for anything else it should be great.

These LED Bulbs work as advertised as replacement bulbs in my light fixtures above my kitchen island fixtures. Saves energy and more importantly cool to the touch as the old halogen bulb burned out one of the sockets which I had to replace and found charred. Only thing stopping me from giving it a 5 star rating is that I notice at night when all the lights are out in the kitchen, these two bulbs in two different fixtures still has a very faint glow all the time. Not sure why this is.

Did not fit. Much bigger. Either my sewing machine uses nonstandard bulbs or this bulb is not common size for sewing machines. Too bad. I’m trying to switch to leds whenever I can.

Your ad description says daylight but shipped yellow lights not daylight at all not happy at all

The amount of light compared to the old incandescent bulb was “night and day”! Amazing difference! You must replace your old bulb with this, don’t wait for it to burn out.

Much brighter the incandescent type of bulb and much less heat. Like moving into the 21 first century with lighting.

Works great.

Very bright. Hopefully a good replacement for a bulb that had lasted many, many years.

Easy to install. Extremely bright. Great value.
