SFTlite 2Pack SBC Ba15d 4W LED Light Bulb 51 LEDs-400 Lumens Cool White 6000K-35W Halogen Lamp Equivalent Double Connect Bayonet B15 LED Corn Light for Sewing Machine/Appliance Lamps

Bulb provides plenty of bright white light. Very satisfied so far but no idea how long they will last. Seem well made so hopeful of long service.

Ideal replacement for old style flaky incandescent lamp - have upgraded my two trusty vintage Bernina 930 sewing machines 👏🏼👏🏼👏🏼*Update* - sadly my machine has now unexpectedly rejected the first bulb and I got a full no quibble refund once both bulbs returned. Shame as it was definitely a great energy saving alternative for the old Riva one.

brighter than tungsten and consume significantly less...

Good replacement, low energy, hopefully will see the benefits of valiue

If like me you’re into Vintage Singer (or Pfaff) sewing machines these bulbs are just what you want. ‘Normal’ modern led bulbs don’t fit the BC15 sockets as they widen just before the actual bulb meaning the bayonet can’t engage, these however fit perfectly & give a good bright clear working light. You’ll wonder how you ever managed with old tungsten Pygmy bulbs! Finally, if you have the 400 series ‘slantomatic’ machines, remove the glass lens in the bulb fitting, you'll get a much more even natural light.

Much, much brighter than sewing machine's original bulb which was great, but the first bulb blew after only two months' intermittent use.

The bulb is great after you get it in. Mounting the bulb is a pain in the proverbial! OK so how was it done? Using a rubber band or thin rubber washer gives the necessary grip on this fiddly tiny bulb. Test it fo a second or two and then remove the band. Simples!

I was fooled. I thought these fittted a normal sized ceiling light bayonet fitting. The Bayonet is tiny! Be Warned
