Rated 5.0 out of 5.0 by Termie Amazing efficiency, good light quality
This is my first A19 LED - I've used PAR20 LEDs of various color temperatures, as well as a great number of CFLs.
Overall, this bulb is simply a great product. I should note, however, that despite ordering this product, I was shipped the 8W (40W-equivalent) model, so that is what my review is based on.
The color temperatures is relatively pleasing - but at 3000K, it's not quite like an incandescent or the 2700K CFLs available from competitors. I'd recommend a lamp shade to cut the bluish tone slightly.
I've posted a picture to demonstrate the directionality of the light - I would not recommend this bulb for placement in vertical ceiling fixtures, as it does not direct any light out of the top, and thus will not shine light down vertically. It will work very well in table lamp fixtures, however.
Overall, I am very impressed with this product. It produces the same amount of light as 11-13W CFLs, while using less energy. It also promises even longer life and no mercury content. If you want to be on the cutting edge, this bulb will deliver, but overall, for price/performance, inexpensive CFLs still win.

Rated 4.0 out of 5.0 by wxray Goodbye CFLs, you've met your match
Finally, a real contender to replace CFLs. I cannot stand the slow start-up and brighten-up time that many CFLs have. No worries with this Ecosmart LED bulb. It is instant on to full brightness. Perfect! I'm confident I'll never buy another CFL.
I try to reserve 5 stars for the ultimate products, and I gave this product only 4. Why? The light pattern. It is not my favorite. That's a minor criticism, but potentially important. For many applications it doesn't matter. In that case, then this is the perfect bulb.
I've addressed the light pattern issue in the attached photos. Basically, there is a dead spot in the center. This may not look good in some down-facing globe type fixtures. However, in an open basket kind of fixture, it may be better. In a regular lamp with shade, you won't see it. So your mileage may vary.
The color isn't bad. It is a bit whiter/bluer than my standard incandescent, but is fine. I also feel it is slightly brighter than my 60 W incandescent. Perhaps it is the color. The good news it is bright, for only 12 W of energy consumption.
Finally, I had to try this in a dimmer circuit. It works! It doesn't get as dim as my incandescent, but that's OK since that's ridiculously dim. It is fine. I can see a day as prices drop that I'll be buying the BR versions of LED bulbs to replace my dimmable recessed lights.

Rated 2.0 out of 5.0 by BasementJack Great but overheats and flashes
First, I REALLY LOVE the unique configuration of this light bulb - the LEDS are on a circle around the middle of the light - there is no Light out the top - at first I thought this would be bad, but there is PLENTY of LIGHT that comes out of this thing.
The other thing I really like about this light is that because it has a bunch of LEDS around the thing, it does not cast hard shadows, which is preferred for my application.
Now for the bad part - And I suspect this is common amongst LED lights....
Although it's only about 12 watts, it generates a LOT of heat - not where the lights are, but down by the base and in the plastic that leads up to the lights.
It shows it's use in a ceiling fan application on the package, which is my use case. Unfortunately, in the ceiling fan fixutre, there is basically no air flow around the bulb, especially the base. (the bulb is "upside down" in the fixture at an angle)
What I am finding is that if I leave the brightness up all the way (I have a dimmer) the bulbs work great for a while and then start to flicker/flash after maybe an hour?
Speaking of dimming - the dimming on these things works great when they are not flashing.
I like the light pattern so much that I may try to substitute the "40" watt equivalent (which by visual appearance has about 1/2 the number of LED's around the circumference - so it's probably more like a 30 watt equiv.)
Also I'll comment on the color -
These are the "bright white" bulbs - 3000k color temp.
I had previously tried the 5000k "Daylight" bulbs and they were just too much - these bulbs are not bad - they do look a little "whiter" than ordinary bulbs - Try one or two first to see if you prefer it over the "soft" white bulbs which are in the 2700k range.
Overall I love the bulb but the flashing is something I can't live with in my ceiling fan application. But the design of the bulb is perfect - I'd encourage the Manufacture to work on the heat dissipation - I suspect a slight revision to this bulb could work just fine in my ceiling fan - so I look forward to what they might do with this over the next few years.

Rated 3.0 out of 5.0 by Bobsyouruncle BEWARE: Not for "enclosed spaces"
I wanted to use it in an overhead light that has a glass globe covering the entire fixture, but the packaging for this bulb has a warning that says "not for enclosed spaces" (which is due, I'm guessing, to the need to have good air flow around the base of the bulb. It gets quite hot, as another reviewer said, and there are open vents along the base). The product description on this web site does not mention the usage restriction. For an open sconce or table lamp, however, I'm sure it would be fine, but for my purpose I'm switching to another bulb that is completely enclosed and that does not have a similar warning.

The color of these bulbs is very nice for very white light. The downside is that although they claim to be dimmable, they seem to be incompatible with the Smarthome dimmers that I use. Unless I place an additional incandescent load with these bulbs, they don't dim properly and they blink to full bright randomly (this was if I used either 2 bulbs or 6 bulbs on the same dimmer). Although this could be a Smarthome dimmer problem, it seems that other brands of bulbs are working in other installations without these problems.

Rated 5.0 out of 5.0 by lilrabbit Great for reading, Coming to market just in time!
After testing this LED lamp in a spare portable desk lamp, verifying that it did work and drew 11.9 watts according to my kill-a-watt meter, I permanently installed it in a difficult to reach hallway light fixture because it just happened to hold the first 23 watt CFL in the house to fail.
I began replacing all of our lamps with CFLs about 8 years ago and have just this year, begun to have a few fail. While I have 2 or 3 CFLs on the shelf, this LED lamp delivers a much brighter light and I anticipate buying a dozen or so of these to replace the CFLs as they begin to wear out.
I was never really bothered by the delayed start of the CFLs, but this LED lamp has no delay at all. It gives a crisp, if slightly blueish tinted light. It works well for reading and general task lighting and I will certainly be buying more.

Rated 5.0 out of 5.0 by timj works fine
Really impressed with the lamp. Works fine with my Leviton smarthome/X10 dimmers.
Just like flourescents, the base will get warm. LEDs operate at 2.2 volts DC, so there is always a cost in dropping that voltage.
I replaced a halogen/enclosed 60w bulbs, and these a just as bright, and slightly "whiter".

Rated 5.0 out of 5.0 by jred Good light distribution, but not as dimmable as some
Summary: Of the LED bulbs I have used, this bulb has some of the best light distribution of any (sending light in all directions), but is not as dimmable as some other bulbs I have used.
First the basics: This bulb is dimmable, has a 25,000 hour rating (not unusual for an LED) with a 5-year warranty, and has a "warm" white color temperature of 3000K. What is significant about this bulb is that it does a much better job of sending light in all directions than most others I have tried.
Incandescent bulbs tend to send light in all directions by their nature, and manufacturers have to use tricks (like reflectors) to get directional light from them. LED bulbs are the opposite, in that LEDs tend to naturally given light in one direction, so manufacturers have to use tricks (like diffusers) to get them to give light in multiple directions.
This LED light does one of the best jobs I have seen so far of giving the same amount of light out in all directions (like you would get from a standard incandescent bulb). Its diffusers are mounted on the side, which but just looking at the bulb would make you think that it would mostly put out light to the side. But when you turn it on, my eye tells me it puts out essentially the same amount of light towards the top, sides, and bottom (base) of the bulb, which I confirmed with a camera light meter. (A different LED bulb I own with a diffuser puts out maybe only 10% of the light towards the base.) So if you are looking for a bulb with light output in all directions like an incandescent, this would be a good bulb to choose.
If you care about dimming, read on. Using an LED-rated dimmer, this bulb dims from about 12 watts down to about 4 watts. That's probably fine for most situations, but is not a huge reduction in light. By comparison, I have another LED bulb that on the same dimmer goes from 12 watts down to less than 1 watt. I use that other bulb for home theater (TV) lighting where I want to really dim the lights, and it works great there. This bulb under review that only goes down to 4 watts does not dim enough for my home theater application.
One other important note on dimming: This light is quiet (no buzz or hum) when dimmed. I have used some LED bulbs that buzzed notable when dimmed, so quiet is not always a given.
So if you are looking for good light distribution in all directions and don't need a large range of dimming, this bulb should be a good choice for you.
