I order a pair of these on a wing and a prayer based on nothing more than the listed specs. Not that there was much choice, intermediate base LED bulbs are almost impossible to find online. These bulbs were replacing the 40W incandescent reading lamps in a large queen headboard. Replacement LED bulbs can be hit or miss since so much depends on getting just the right combination of individual LED placement within the new bulb, the beam shape put out by the LEDs, the brightness, the color, and how fixtures designed for a spot incandescent bulb effects that particular replacement LED bulb.

In this case, it was even better than I had hoped. The front firing LEDs on this bulb worked well with the placement of the reading light sockets above and behind my head while lying in bed. The light output was much greater and had a smoother beam than the incandescent bulbs that were replaced. Much of the old light was lost due to a poor small reflector. The small optics over each of the 9 small LEDs in this bulb directed the light right where it was needed. I am considering these same bulbs in E27 medium bases for some recessed hall lights in my home. So far my only concern with these bulbs is long term performance. These bulbs don't have large heat sinks which makes them great to fit in smaller fixtures. The downside is that heat is the killer of LEDs. After leaving the bulbs on for extended periods, there does not seem to be excess heat buildup. But the extensive use of plastic in this bulb with almost no metal visible could foreshadow heat buildup problems in the future. So far the heat seeks to be dissipating well through the base.

Note: Pay attention to the color in the bulb description. These are available in different color temperatures. Personally, I like the near-daylight 5000-5500K versions that I purchased even though this color temperature is harder to find. There are some people who dislike the "blue tint" they see in such bulbs. If that's a worry, order the 2700-3000K bulbs that are closer to the "yellow tint" of incandescent bulbs.

We have Ikea lamps that use E17 bulbs but we didn't want to use regular bulbs during summer because they produce so much heat. After looking for them everywhere online, I realized that the only two LED options were these and Ikea's bulbs. You can't order Ikea online unless it is from a reseller and we didn't like their bulbs because they are yellow (warm) light. These Aubing bulbs are white light at a reasonable price and safe a lot of money all by themselves and by reducing heat during summer.

Incredible power for an LED. It shoots out about 50Ws of light. I used it to refurbish all my IKEA LAGRA Spotlights.

The LED lamp is working as expected but the supplier has been a pain in the butt. I complained about the the length of shipping time which was reported to be several weeks to over a month. Since that complaint I have been inundated with emails from the supplier. As it turned out I received the lamp 13 days after the order, which I consider too long. Next time I place an order I be certain it comes from a supplier in the states.

Great. Runs so cool you can put your hand on the elements .. hot but not untouchable. This color temp is "cold"/blue compared to the other model but not unuseably so. Brighter (yes) than the (hothothot) halogen it's replacing. I don't doube that producing these things generates considerably more pollution than conventional bulbs, but consuming 10% of the power over possibly 10x the lifespan, I'm hoping it's a wash or a win.
