These recently have come out in 2700K and now 5000k which is the daylight bulb. I have purchased these at HD for less than amazon. They are the best I have ever found. They are bright enough and are most like an incandescent bulb you will find out there. They have a plastic type skin on them which seems a little weird at first but they won't slip out of your hand, thats for sure. They don't get hot to the touch and nothing on the bulb or the packaging says that you can't use them in an enclosed ceiling fixture.
My advise is to get a bunch of these and replace all of your light bulbs which will save you money in the long run. This is what I'm doing.

Get this from Home Depot for under $13.00.After trying out Higtlights, which I bought for the same price and gave five stars, I'm going back to rate them four stars and instead crown the Cree. The Cree bulb is more like a traditional bulb. The light output, color, and distribution are virtually indistinguishable from the incandescents we replaced. We even replaced a couple of 100w bulbs and felt like these were good enough. The 40w equivalent is also good. Very good value, assuming they last.
Best Deals for Cree 9.5-Watt (60W) Warm White (2700K) LED Light Bulb
I just bought 8 of these from Home Depot last night. HD carries these for $12.97 each!!! These appear to have about the same brightness as the 12.5 watt Philips LED bulb, and don't look nearly as odd! The Cree bulbs turn on noticeably faster than the Philips, and much faster than a CFL. Turn on time is basically instant. I also bought 2 of the 40W LED bulbs for the bathroom, and I like them so far. I believe the 40W Cree's were $9.97 each at HD. I am very pleased with the purchase, and will be buying more very soon, just not from here :)I did some looking around on Cree's website. Cree has an exclusive contract with Home Depot to sell these bulbs. That means, if you buy it from this supplier (M.R.S. Industries, or sold.123, or SOLD LLC (They keep changing names lol)), you are paying them over $10 to drive over to Home Depot, buy the bulb, and mail it to you... $23.19 here, or $12.97 at HD, who also has free shipping if you buy the 6 pack and drops the price per bulb down to $12.47... Fair warning!
UPDATE 8 Apr 13:
These lights feel cool to the touch compared to other LED's. Cree's website says they are not designed for enclosed fixtures, but I decided to try it anyways. I have a 2-bulb closed fixture in my kitchen that now has 1 CFL and 1 Cree LED in it. Not sure how long it takes for any heat buildup to negatively impact bulb life, but I'm gonna give it a try. I will update if it dies on me.
UPDATE Sep 1st 2013:
These bulbs are still doing great. I even have some in fully enclosed housing, and I have seen no negative effects so far. I also wanted to add that if you are military (like me) you can get your military discount from HD after you order online. You just have to Call their customer service line and they will adjust the price. I wish I would have known this months ago :(
Also, I dropped one of the 6W CREE LED bulbs 7' onto the hardwood chair I was standing on. The outer glass "shattered", but because of the silicone coating it acted like safety glass. Even though it shattered it still held together, and I didn't have glass everywhere. I went ahead and screwed it into the socket, and it has been working fine for a few months now. If you were to look closely you can see the shatter design in the light it puts out, but since it is in a frosted enclosed fixture you can't tell unless you really look for it!
Honest reviews on Cree 9.5-Watt (60W) Warm White (2700K) LED Light Bulb
Finally an LED bulb that behaves like a good old incandescent bulb at a fraction of the energy consumption. Most LED bulbs for household use are very directional, that is to say the light goes in more of a beam than the glow in all directions of a traditional frosted glass bulb. This one comes very close to being omnidirectional. Of the two varieties, this version in a color temperature (2700° Kelvin) is closer to the warm white of a tungsten filament or halogen capsule filament bulb.Note: The higher the "temperature" number, the more blue-white it looks. In a home environment the blue-white color can seem harsh, sort of like an old fluorescent light tube.
The light output of the 2700°K example under review is 800 lumens, about the same as a CFL or incandescent rated at 60 watts. Power consumption of the LED array is just 9.5 watts at 120 volts. This unit is said to be dimmable, but I have it in a conventional hooded desk lamp so that feature has not been tested.
Two things are curious about this bulb -the outer "glass" is coated in clear plastic like a shatterproof industrial shop bulb. It is sticky to the touch, and in an exposed lamp the surface might be attractive to dust. The other characteristic is that the vertical flanges seen between the metal base and the frosted glass run quite hot for a 9 watt bulb. It feels more like how hot a 60 watt bulb would get. Those flanges are designed to dissipate heat created by the LEDs as they produce light, and I have to assume it gets hot, thermally, as a normal running condition.
One other characteristic to note -the bulb is about a half-inch longer than a traditional incandescent bulb. It should fit in most fixtures, since that's within the range of heights you would find among halogen, 3-way and higher wattage incandescent bulbs.
I am delighted to see on the packaging that this bulb is "assembled in U.S.A." There is no country of origin on the bulb itself, but that's me being a skeptic.
The heat issue is significant, which is why I've marked it at 4-stars instead of five. With the heat concentrated near the socket, some sockets could eventually suffer damage from prolonged temperatures that were not envisioned with bulbs where most of the heat was up in the glass and away from the electrical contacts. In my application, the bulb is horizontal rather than upright (base down, glass up), and the metal shroud on my lamp may aggravate the amount of heat that can build up. But so far, in the first hour of operation, the metal shroud is COOLER than with the 40 watt halogen it replaced.
----------
UPDATE
I have improved the rating to 5-star after observing that the section between the metal base and the flanges is acting as a thermal insulator. The flange area gets quite warm -too hot to touch, really -but the heat does not spread to the base. So, there is less basis for concern about potential damage to the electrical socket into which this bulb is placed.

Just installed several of these Cree light bulbs. They work great. Replaced CFL bulbs which I had used to replace the old fashioned incandescent bulbs in the bathrooms, kitchen and study. Haven't tried them with a dimmer yet so I can't comment on their operation with dimmers. However, as a straight up replacement for CFL or incandescent bulbs they're great. The light they produce is warm ike the light produced by an incandescent bulb, but at a fraction of the cost and they're guaranteed to last for 10 years. You're not sacrificing quality or lighting ambiance to use these bulbs and their energy savings is spectacular. One comment on the price. They're being offered here for roughly twice the price as elsewhere (see Home Depot). Sorry to have to mention this but exacting a premium for something special or out of the ordinary is one thing, out and out gouging is quite another. Get these bulbs, but get them elsewhere.
