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 have always bought the bulbs for my Singer 221 (Featherweight) from the well knows FWS. I loved the bulbs, but hated the price. I purchased these in warm white as the bright white tends to reflect green on the older shellac finish of my sewing machines. These are a great alternative. They are not as bright (only by a smidge). They seem very well made and there is no flickering or humming. They also work great in my other machines, including my Bernina 930 Record, my vintage Kenmores, and my other vintage Singers.

Arrived quickly, bright. Not as hot as the previous incandescent bulb.

Thought the description says Special Feature Dimmable, they are not dimmable. When I put them in light fixtures with a dimmer switch even with the switch turned up to the highest setting, they were dim (think barely as bright as a night light) and they flickered. I dont know if they are any good in a non-dimmable circuit, but I will never find out. Returned for a refund.

Tried to replace the 30 watt incandescent in my Kalart 8mm film editor but the LED wont cast the light enough to light the film frame. Unfortunately I ordered a four pack and cant use them.

Nice, really bright replacement for halogen bulbs. Much cooler and brighter, and correct color (2700K).

I was not sure if this would fit my Vintage Panasonic Vacuum Cleaner but it does. Its also very bright. Recommended.

Needed a replacement bulb for my old (1980s) Craftsman 12 inch bandsaw. Original was an unidentified incandescent bulb. After using dimensions found for various bulbs compared to the original, I tried this one. It fits perfectly and the light is much brighter than the original ever was. Made my old saw easier to use as I can see my workpiece far better than I was able to in the past.

I am delighted with this LED sewing machine light. This bulb provides a good white light. It is brighter than a conventional bulb, and it doesnt get nearly as hot. The bulb is easy to install.

Fits the Singer Featherweight and is much brighter than the original incandescent light.

Brighter and whiter than the incandescent sewing machine light it replaced.
