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

I bought a four pack of these. They are much brighter than the incandescents but not TOO bright. I can see much better. The breakdown; 1941 Singer 66-16; fits perfectly, works great. 1921 Singer 99; perfect Mid 60’s Sears/Kenmore 158-1503; again perfect. My 1918 Singer 66 has a screw-in bulb so it’s a no go. I’m very happy, recommend these to anyone and everyone. Hopefully they last. I’ll keep buying theses until my eyes get younger.

Fit the machine perfectly and makes sewing so much more visable

Very bright, at a much lower temperature. The original bulb made the sewing surface very hot.

Praise the bones !!!

This is not super bright like I was hoping. Mediocre.

I had to file some of the solder contacts off to make the LED fit an old (1970 model) Singer machine yet an 80 year old, it fit just fine. The white light makes it easier to see while sewing. Good value. The long term question is how long will these last in a closed enclosure found on many sewing machines that don’t offer good cooling for a LED type bulb?

bright light

Great value. Very bright, love that. Standard easy install.

Replaced the old halogen bulbs with this, each halogen bulb was about $8 vs this set is 11. I do have a dimmer switch and installed all the new bulbs and tested with the dimmer no issues at all. Definitely recommend.

Wonderful product. Will buy again.
