I purchased this bulb from Target and it works for its purpose (as an outdoor lantern light) but I am disappointed with the technology. I'll make a quick comparison to illustrate this.
This GE LED bulb cost around $15 per bulb and is guaranteed for 4 years (the package say "last 8 years" but the guarantee is only for 4 years) that is $3.75 per year just for the purchase which is pretty high. This bulb uses 2.5 watts to produce 80 lumens of light. That's 32 lumens per watt, not bad but not great. Also this bulb is not intended for "enclosed fixtures" so it is no better than a CFL in this regard and not as good as an incandescent.
Now compare that to a Sylvinia CFL I just bought. It cost $7 per bulb and is guaranteed for 13 years, which is $1.85 per year for the cost of the bulb. Not too bad. This bulb uses 5 watts to produce 200 lumens which are 40 lumens per watt. This means the CFL is 20% more efficient than the LED. The down side is that this bulb is also not for "enclosed fixtures" and does take a while to "warm up" before it is producing full light.
In the end the Sylvinia CLF is more efficient, it is guaranteed for 9 more years that the LED, and the CLF is half the cost.
In theory LED's should produce more lumens per watt than a CFL, and should not be as effected by enclosed fixtures because they don't produce as much heat as CFL's but that technology isn't captured in this bulb.
I won't buy another LED bulb like this until they have made major improvements on output, longevity, and brought down the price.

I bought 3 of these as a test for a whole-house re-bulbing wanting to get away from the CFL's (mercury) and make slow dollar gains on the longer lasting and lower wattage LED technology.At almost $18 per bulb, I was reluctant to buy, but they were from a respected maker and with free shipping.
They are smaller than your standard light bulb, which is kinda nice since they tuck into my glass fixtures and almost hide there, BUT their light is very soft. I have 2 3-bulb ceiling fan fixtures in my living room, one loaded with these, and the other has a single 13-watt CFL in it now.
I am certain that if I had 3 of these LED bulbs in each fan, I would find myself wanting more light at times... I think they'd be better in a place where soft light is desired, and am not sure if a single bulb would be enough for even soft light applications.
At this price, I cannot recommend them. If they were 40% cheaper, I would reconsider.

I got this to replace the 40W lights in my refrigerator. They work a lot better than the Nanolux 3W light I had before.Light output is about the equivalent of a 25W incandescent. It's slightly bluer than an incandescent, but quite pleasant, not at all like some LED lights. For my fridge, the brightness is adequate, but it's noticeably dimmer than the 40W it replaced. The form factor is a perfect match.
The best part is the lack of heat from the bulb. My fridge does not have a cover over the light, so I could really feel the heat whenever I was reaching past the bulb. With this bulb, I can grab the bulb while it's on and not feel anything.
It's too early to comment on lifetime, but based on past experiences with LED's I expect no problems. I had a LED light in my freezer compartment for 2 years now and never had a problem, even though it probably gets some condensation whenever I open the door.
If this was a 40W equivalent brightness, I would give it 5 stars.
