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

Really bright. Love it for my sewing machine.

Only needed one for a night light, wanted to replace an incandescent bulb to prevent heat build-up, works fine.

This is the replacement for a bathroom light that uses 3 such bulbs. They are not easy to find as they are xenon bulbs. This was the right one.

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

We moved into a new house, and some of the beautiful light fittings use light elements that get very hot. We replaced ones this size with these, and the resulting half bathroom is now no longer getting so hot, and is using a lot less electricity

It sticks out of the sewing machine’s light housing - too long Other that that, a great upgrade for the stock incandescent bulb

I used this to replace a missing bulb in my Zenith 7H820 radio from 1948. it works great and is much, much cooler than the bulb that came in the radio

A perfect replacement for the lamp in my 1980s vintage Royal (brand) upright vacuum cleaner.

this is so much better then the old bulb. Its a nice crystal clear white light and you can really see so much better with it then the original bulb. Also, it doesnt get as hot and you can feel the difference in temperature. Good upgrade.

Very happy with the brightness.
