I rarely write reviews but I'm genuinely thrilled with the light from this bulb. I am using it in recessed cans in a windowless basement. The 5000k 1100 lumen light from this bulb is as close to sunlight as I imagine I'll ever find from a bulb. Makes the whole space feel soo much better compared to the GE Reveal R30 bulbs that I was using previously. Even though it is a VERY bright bulb(don't plan to look directly at this bulb) I don't get the same harsh shadow line along the top of the walls of the room(making the room feel smaller) that is common with most recessed lights. It works perfectly with my dimmer switch. Please note: ALL LED and fluorescent bulbs lack the color shift to yellow that we've come to expect from a standard incandescent. Also, they only dim from about 100% to 10%. The net result is a dramatic reduction in lumens while keeping the 5000k color temperature. If you want the 'romantic' affect of a dim yellow light you are better off with scented candles.
This bulb is rated for 25,000 hours... which based on what I've read, means that it will produce about 70% of the initial lumens in about 8 or ten years. I suspect once I have a few more of these installed in my basement I'll feel a need to turn the dimmer down a bit and then over time as the bulbs lose lumens I'll be able to turn the dimmer back up and never know the difference. If you are afraid that 1100 lumens is too much just install a dimmer. You will be pleased. I'd like to compare this bulb with it's 2700k sibling, but that's mostly out of curiosity. I like the bright sunlight affect of this bulb and can't imagine preferring a warmer light.

Rated 3 out of 5 by GeorgeM Start delay
The color of this bulb is nice and it dims well, but there is a perceptible start delay. It seems to take about half a second longer to start than the other bulbs I'm trying out in my living room. When the kids were playing with the light switches, this is the only bulb that had trouble coming on after switching them on and off quickly for a few times. I expect that this one will last long.

Rated 5 out of 5 by amalak Great Bulb for the Price
This isn't the first Kobi bulb I've bought, and like the others, it doesn't disappoint. I have them in my living room in recessed cans. They look just like the incandescent bulbs they replace.

Rated 1 out of 5 by kcarr Bulbs not sealed lets bugs into plastic lens.
I have 8 of these lights in a covered area outside. After several weeks I noticed the lights looking dimmer and after taking them down the fins are open where the plastic lens is attached. Man the bugs are attracted to the leds inside where they die and fall inside the bulb and the plastic lens collects them. Useless, useless, useless. If you are going to use leds outside make sure they are sealed.
