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

The light is bright and white in color. It has a bayonet base that twist to lock in place. The lamp is 120 volt LED. It fit our Pfaff 44 sewing machine perfectly.

Fits my Pfaff perfectly.

Not only does it keep the machine cool to the touch, its also brighter and has a higher angle of incidence across the needle assembly, giving you more light in the sewing area. After installing it and running the machine at high speed Im not seeing a downside.

Perfect.

The bulb is bright and exactly what I was hoping for. I was being lazy and didnt measure the distance in my machine, from the socket to the opening. Because I was lazy the light sticks out a half inch but the light doesnt get hot and it throws off more light over the entire surface so Im OK with that. I knew that might have been an issue going with the longer bulb. My bad. I purchased the 7.5w daylight and I should have just purchased the 4w to avoid it sticking out from the cover plate on a Janome CoverPro. This is not an overpowering blue daylight, still a white daylight just very clean without a blinding blue cast...in my machine anyway.

My wife loves it. She wanted something bright and white. This was perfect.

Didnt want the hassle of replacing the original bulb for my GFs 1920s Singer machine so I asked her if I could put an LED in it. She said yes and this was a PERFECT fit with the **DOUBLE CONTACT BAYONET**.

Wonderful product. Will buy again.

Used in 2 kitchen bar lights. They were great for 2 weeks and then barely emitted light. Changed out with the same results. Went back to incandescent.

Im using these LED lights in bathroom fixtures. Compared to the halogens they are replacing, they are definitely white in color temperature.
