DiCUNO E12 LED Bulb 4W (40W Equivalent), Warm White 3000K, 400LM, 6-Pack

Good quality and doesn’t get hot

Used these to replace KX40FR/E12 which cost about $17 each. At $2.50 each, these are a huge bargain but I was skeptical of mixing LEDs with existing bulbs. I shouldn't have been -- the color and brightness match the older ones exactly. The physical appearance is different (of course) so if the bulbs are visible in your fixture, these might not be for you; but if the bulbs are hidden, these are a perfect match.

We are using these lights to replace the incandescent C-7 bulbs that insert into Lemax ceramic miniature buildings and other small scale ceramic buildings that we have painted ourselves. These bulbs are not dimmable and very bright, so the buildings glow through the walls a bit (see pictures), but we like that effect. I am happy that they run warm but not hot because I have had to custom fabricate the mounts for some of our houses and I want to be VERY sure to avoid a fire hazard. We have them on each night from 5-8 p.m., and they have lasted well over a week so far. All that said, these bulbs are slightly longer than an incandescent C-7 bulb, and that created a tight fit in one building, so I am NOT sure that they will fit all of the Lemax or other brand miniature ceramic buildings, but they have fit all 12 of the buildings we have bought so far.

This is an absolute wonder. A little teeny tiny bulb that works just like a regular night light bulb. I needed one of certain wattage and this one fit the bill for a lamp that I have. A bit pricey, but you do get several.

These bulbs are not as bright as the others that I have but work. I have no idea what the longevity is as I just started using them. Probably last longer than me.

I am using one of these to replace the light bulb in my Harbor Freight drill press, and two more as the nightlight bulb in two table-top lamps that have two bulb sockets on each (the other holding a full-sized LED bulb). These are a nice color temperature (white but not too cold) and generate more light than expected. They look a little funny compared to a normal light bulb, with the visible diode elements, but that's not uncommon for LEDs and doesn't hurt anything.

Am using three in one ceiling light fixture The small bulbY size is a nice feature. The light is sufficiently bright. I liked that metal shroud was retained entirely in the socket instead of protruding out like in other brands.

Purchased these to replace the lights on several of my Christmas airblowns. The airblowns are now brighter, look better and can be seen.I've also used these for salt lamps in hallways and areas I want to keep lit at night. - Love that it lights up the area. The light itself is bright, however, once placed in the salt lamp, the pink salt softens the brightness.Haven't had them long enough to rate longevity or energy efficiency. In general, LED bulbs are supposed to be energy efficient and last longer than incandescent bulbs.
