Ziomitus BA15D 120 Volt Double Contact/DC Bayonet Base Led Light Bulbs 50 Watt-75 Watt Replacement, T3/T4/C7/S6, 2700K Soft Warm White BA15D 5W Led Sewing Machine Bulbs, Non-dimmable, 5Pack

These appliance LED lights are so much brighter than the old incandescent ones. This one works on my vacuum cleaner, and I could even vacuum in the dark.

it works

It actually fits my Singer sewing machine 401a. It does not get hot after many hours, which is great. My original bulb would burn you. Makes great light and you get several so it good for the price.

So, the first thing to know about these bulbs is that they are considerably bigger than the incandescent kind of the same type and base, so you need to make sure you have adequate room for them. They installed just fine for me - harder to get the old bulbs out than to put the new ones in. At full brightness, they seem to be quite similar to the incandescent - even in color - when viewed in a fixture with frosted glass. A bit sharper light pattern, though, but even. Pretty nice for only using 10% of the power! The only downside is the dimming. The brightness doesn't go down that significantly from 100% to 30% - much brighter than an incandescent. They go out at 20% while the incandescent are a nice warm orange, even down to 10%, perfect for when getting up in the middle of the night. At least there is no flicker. But this lack of dimming low means I will keep the incandescent bulbs in one of the 3 fixtures that are side by side.

Great replacement bulbs for vintage Featherweight sewing machines. The bulb does not get too hot so the metal housing around the bulb no longer burns my arm. It is very bright (much brighter than the old incandescent) which is perfect for seeing your work. Quick and easy to replace.

Worked perfectly in my Delta grinder Twin Lights. Much better visibility now.

Everything was great (bright, cooler heat temp compared to the incandescent, proper color temp) about the 2 bulbs except they start to fail about a few months. While used in a dimmer, we just leave at 100% and turn the room light on and off as needed like any ceiling fan light for a room. It now flickers intensely and continues to get worse. I replaced the bulb with the other bulb in the pack. It worked fine but only last about a month before flickering just like the first one. Very disappointed.

These bulbs are the perfect replacement for the old halogens. They are high quality, bright and dimmable without flicker. I am very impressed. I hope they last for as long as advertised.

So far they are good. I really only needed one but it still made sense to buy the pair as it would have been the same price for the single halogen lamp which it replaced. I would have been happier I think getting the warmer colour but that was just a poor choice on my part.

The light bulb works, sure.....but it is quite dim. No where near the brightness of a Halogen 100 Watt bulb.

That one it was so small than the one I want I wanna return because I didn’t use it and thank you

The product was not as advertised. I ordered and needed an E11 bulb. The package says E11 but the bulb is actually closer to an E12 and therefore the threading base is different.
