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 sewing machine gets used over 20 hours per week, and this bulb has been in service for about 6 months . Its wonderful with a cool natural light that makes it easier to work. No problems with heat. Its good to save energy, improve comfort and performance, get the right technology into place at a reasonable price, and then forget about it, except to recommend it to others.

This was a great replacement bulb. I would prefer it if it were a bit brighter. It was harder to install than the one that was in it ( I believe the LED was just a bit smaller). However, it is difficult to change a bulb on my machine and that is no fault of the seller of this bulb. I can recommend highly the bulb and the price.

Bought these for a customer (bathroom wall lights) original Halogen bulbs kept burning out quickly so I recommended these . Nothing like a happy customer : ).

I wanted to try LED for my vintage sewing machines to reduce the heat and fire risk. These are nice and bright and clear. I prefer a warm glow but bought the standard which is a bit blue but it works great!

This was a perfect fit in my Elna Stella ZZ and Air Electronic SU 68. The whiter light looks so much more modern and makes it much easier to see.

I like it because it is cool, the replacement light bulb I brought from Amazon is sooo hot, burn my hand after 3 mins turn on. I wish they can sell the light bulb singlely because it should last a long time. the light is not as bright as our original bulb, I think its ok

good product easy to use with Featherweight or 301 machines.

Very bright. Hopefully a good replacement for a bulb that had lasted many, many years.

I put them in many customers machines to rave reviews. very bright. stay cool.

Models 201-2 and 15-91. Thats the only ones Ive tried them on.
