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

Brightness

These bulbs are a massive improvement from the yellowish, old incandescent bulb I had in my sewing machine light. I can see black stitching on black fabric and make any necessary ripouts without fear of catching the wrong thread. It operates without putting out excessive heat, so the outside of my machine by the shuttle no longer gets hot. Im very glad I bought these bulbs!

Bright, easy to install, and it came with a second bulb.

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.

Purchased to replace the (burned out) sewing light in the spouses Singer Featherweight. The 2nd bulb is on standby for one of her other machines (if I dont nab it first for one of my vintage desk lamps) Good light, not too bright and its not far off from Daylight temp so easy to see the real color on the stitching.

So far so good. Being used for outdoor patio lighting. I’m happy with the results

15 times brighter than a standard incandescent vacuum bulb. Now I might actually be able to vacuum without the lights turned on !!!! Lol

This is a bright bulb, just what I needed for my sewing machine. And it uses less power than my old bulb.

Not much to say rather than the lighting temp/Kelvin is great and easy swap out.

Only half of each bulb lit. They were tight to get into the socket. I sent them back for a refund and did not reorder.
