This was the first LED bulb I bought, and I am very happy with it. It provides a nice bright light without an artificial look. The soft white is just right for our fixture. We put it inside a new garage fixture which was the perfect choice.

10 yrs warranty
I've replaced most bulbs with led bulbs for the last couple of yrs.
this morning, the cover of bulb was falling down . I didn't know led bulb has this defect. cree gives 10 yrs warranty but to get their warranty, I have to send request mail with some documents which I don't keep for one bulb.

Bright, Good Color Rendering, Burns Cool
The CREE leds are the best replacement for incandescent bulbs, and toxic compact fluorescents too. Here in NC. the power company subsidizes the bulb cost making them affordable. I have purchased them a few at a time to spread out the cost, and now almost all the lamps in our home have CREE leds, including the recessed fixtures. The color is soft and even, radiating from the sides of the incandescent shaped bulb, making them indistinguishable from incandescents or halogen even. Only the little white metal heat sink above the threaded base becomes warm during use, saving on air conditioning, the bulb remains cool. i use the 40W equiv leds in lamps that have multiple sockets, they are plenty bright. The label says these can be used in enclosed fixtures as well. The CREE leds are now available in 75W, and 100W equivalents, as well as the 60W and Par30 units previously available, so there is a perfect replacement for any situation. Outdoors, they light instantly, whether cold or hot, and worked great this winter when it was zero, the compact fluorescents would not even glow at that temp. We have many antique tiffany lamps and antique sconces/ pendants, and the CREE leds look like a real light bulb, not a weird curly thing, when they are exposed. They do dim OK, but the color is different, somewhat cooler as it dims-not warmer like incandescents. It woks best to turn them on bright and then dim, rather than the other way around, as they need a certain amout of voltage for the electronics to light. there is a very slight hum or ring when these operate, especially when dimmed, I can barely hear it, but some may be sensitive, so give one a try first if you think that might be an issue.

Cree 8.5 Watt (40 Watt equivalent) TW Series dimmable
Makes humming/buzzing noise at all levels from dim to bright even with Lutron Maestro dimmer switch designed for CFL and LED bulbs. Although the bulbs do produce full range dimming, the noise is too distracting. I returned the bulbs and replaced them with Ecosmart 8 Watt (40 Watt equivalent) G25 Soft White LED dimmable bulbs. The Ecosmart bulbs are buzz/hum free. I noticed that both Home Depot and Amazon reviews for the Crees have many poor ratings for noise.

Great value. Good quality for the price.
This LED Bulb is a good value for the price. I only wish it was the Cree TW Series of LED bulbs for this price.
TW Series provides one of the most beautiful and natural LED lights ever produced, with a nearly unmatched Color Rendering Index (CRI) of 93.
However, this bulb is close to a typical incandescent warm white bulb.

Great bulb for bathroom lighting.
Used 8 of the Cree 40 watt bulbs in two bathroom fixtures. They provide perfect lighting for the entire bathroom. Very little heat generated by the LED bulbs.

A great LED bulb
These bulbs, much like the CREE 60W equivalent bulbs, are nearly indistinguishable from an incandescent bulb. I bought six of these to install in our primary bathroom fixture and am very happy with the results. My only complaint (and it's minor) is that there appears to be two variants of this bulb. With one, there appears to be LEDs on the top of the corncob inside the glass. For the other, there does not appear to be LEDs on top--this results in a slightly unlit part of the bulb (just the very top). For most applications, this isn't a big deal. Mine are installed just below the ceiling, so half of the bulbs have a small shadow above them, half don't. It's still not terribly noticeable; it took me 2 weeks after I installed the bulbs to notice it. In the attached image, you can see a slight shadow on the two outer bulbs.
Overall, I'd still buy more--I just wish I knew how to tell the difference on the packaging.

Looks Great in my Ceilng Fan and Dims Perfect!!!
Was skeptical if they would dim in my ceiling fan. Saw them on sale this evening for $5.97 and could not resist so I bought 2 to try. Placed two in the fan and dimmed the fan all the way down. The Incandescent bulbs actually cut out before the LED bulbs. These bulbs can dim way down. I'm using a 7 year old Hunter Douglass Ceiling fan with hand held dimmer switch and it worked fine. Went back and bought several more for this price. See pics. I tried to show how they look dim. They dim pretty much as well as the incandescent bulbs if not better. They also fit well in the globes. Was worried they would stick out but they fit similar to the regular bulbs. Only thing you can notice is the small black spot in the center of the bulb, Not a big deal. Plan on trying next outside in my dusk to dawn photo cell lights.

Incredible!!! 6-WATT (40W) is brighter than 60W incandescent.
This is unbelievable! This 6-WATT (40W) is brighter than 60W incandescent bulb I had in my home. The color temperature is perfect, not so yellow or white. I am happy I chose the soft white, its color temperature is similar to incandescent but a bit whitish and it is really nice. Finally a bulb that I really needed. I think people should not even care to look at other bulbs... this is the one to chose. Check out the picture, I have a 60W incandescent (Left) and 6-WATT (40W) (Right) side by side. 6-WATT (40W) is brighter.

Made in USA says it all
I am currently testing the 9.0 watt daylight version of this bulb and WOW am I pleased. Let's just say that this thing makes a LOT of light for the watts it consumes. It has come through many different uses including closed fixtures pretty well. Though I agree with the above reviewer. Use the 6 watt version for this so it lasts longer. Electrolytic capacitors degrade quickly at high temps. The heat levels get a bit higher when it cant get air over the heat-sink. In free standing or table lamps or in any application where this thing can get air, there is NO comparison to other bulbs at the same price point. I like the neutral white light option as I always hated the reddish color of indoor lighting, but the warm white version nails the warm white color pretty much on the head. They also make a 9 watt version of this light for indoor floodlights. Another one I am anxious to put through its paces ASAP. So far a great product with local control of fabrication of the LED's. Find Cree's website for more info. These little bulbs are only the beginning of what they make. No Chinese shortages of critical parts to hamstring product quality or price.
Other things that I have noticed:
* Work extremely well with power inverters, both
modified sine and pure sine wave. This makes them
IDEAL for solar
* I am unsure how they will perform yet on a generator
I think they will be ok on an inverter type unit, but may
not like running on the older non inverter type. Ive
destroyed several other LED bulbs doing this. Will test.
* I've only detected VERY little RF from the tiny driver
circuit in its base. It may have been noise simply
present in the line feeding the unit. Lots of harmonic
distortion on the grid these days.
The other reason you should buy these, is that they are made in America, keeping our citizens in honest jobs that keep money here, on our shores. Why should China light our homes when we can make our own, and at better quality and price point. Think of all the houses that will use these and you see very quickly that LOTS of money will stay in our country and many workers can feed their families with pride. As long as the quality is there, and Americans make these, they will be in my home. The more we buy, the cheaper they will get once mass production fully kicks in.
