Ba15d 5W LED

Super bright! Use these on my 1930s Rockwell bench grinder. It takes an oddball light, not sure if it was factory or not. But these fit great and hold up way better than the standard bulbs I kept installing.

Worked perfectly to replace my halogen bulbs.

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, 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.

Good fit. Dims in steps. (Non linear)

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.

I can't comment on longevity because I just got the bulbs. We have a bathroom that uses 6 halogen T4 base bulbs. It took me some googling to figure out which bulb and which base. I then found this one. First the color temperature looks like an almost perfect match. I was oscillating between 3k and 2.8k but this is just right. I took a pic of the fixture and there are 3 bulbs in the fixture. The middle one is this LED and the two outer ones are halogen. Can't tell the difference except the halogens are burning hot. Only irritation for me is that I need 6 and this came in a 5 pack so I just ordered another 5 pack. I'll have some spares.

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.
