Light: The white version casts a very cold light. It's too "cold" for my tastes. The warm version is much better, but still much cooler than an incandescent bulb. Its brightness seems close to that of the incandescent, even though it uses 1/12th of the energy wow!
Dimming: I put it in a dimmable dining room fixture that has five 60 watt incandescent bulbs, replacing just one of the bulbs. It was easy to tell which of the five was the LED bulb because the light was colder. It also did not dim the same way, although it does dim. The LED dimmed much more slowly. When the incandescent bulbs were almost dark, the LED was still shining at a moderate brightness. As it dims more, it suddenly shuts down and goes dark.
Overall I like these, even though they are very expensive, it's worth having a few in strategic places. I would not use an LED bulb next to an incandescent bulb because of the difference in the quality of the light. I have the warm bulb in a hallway that I often leave on for long periods; the white version is in an outside porch light that comes on at dusk. I'm mostly using CFLs right now, but will probably switch to LED lights as they burn out hopefully the cost will come down by then. I would only buy the warm light version. For now I would only use them in non-dimmable fixtures, partly because of how they dim, and partly because of the price.

I ordered a few different types and wattage of LED bulbs from different manufacturers to try out because I've dropped 2 CFL's over the past 6 months. I have been very happy happy with my Panasonic CFL's the past 5 years, but now that LED's have come into their own I feel that the time is right to make the switch as I'm not a happy camper cleaning up mercury, regardless of how minute the amounts, in my home.It seems to me that the latest version of this LED bulb that I received has been upgraded from 5 to 6 watts, even although the part number remains the same i.e. 1012WH.
The bright white color is a little too harsh for me and seems slightly higher than it's rated 6000K. I would rate it more like 6500K which is similar to bright midday sunlight on a summers day harsh and very bright white. Ideal for displaying diamonds, jewelry and other objects that look good under this bright white light, but it's just a little too disconcerting for home use in my opinion. Warm white, the warm glow of sunrise or sunset, which is about 2700K, is way too yellow for me. I generally prefer home bulbs to be around 4000K, especially for reading, but no higher than 5000K. The quality and uniformity of this light is excellent. Keeping in mind that coverage is quite a bit less than incandescents. Probably about 190 degree forward coverage versus about 300 for the latter. This makes it an ideal candidate for shop displays and photographers who want to mimic outdoor sunlight. But it would be hard to relax at home with such a harsh bright white light.
Brightness is about the same as a 13 watt CFL, and I would rate it equivalent to a 50 watt incandescent, which is more than adequate brightness for most home use.
Please note that I have given it 5 stars because of the excellent quality and brightness of light produced, notwithstanding the fact that I find it a little too harsh for most home applications.
August 26, 2011 Added two pics with notes and labels to give potential customers some idea of the differences in color and light output. No camera can accurately capture the color or dynamic range of the eye, but rest assured that none of these bulbs produce a greenish cast, and although the 6500K bulbs are harsh white, they don't look bluish to me. IMHO the manufacturer's product pic accurately captures this bulb's intense white color.

this light bulb produces light similar to what moonlight looks like: blueish, and vague. it has been rated as being able to replace a 50 watt bulb which is wishful thinking. I would rate it more like a 25 watt bulb replacement. by itself the color is just awful, but I mix it with a warm light bulb, which makes it bearable. I was disappointed and do not recommend this product. In short: low output, awful bluish color.Honest reviews on Ledwholesalers 7 Watt Dimmable LED Standard Screw Base 50 Watt
I compared two similar LED bulbs, the Dimmable Standard Screw Base A60 LED Light Bulb 5 Watt Globe, white 1012WH ($21)with the Dimmable E26 A60 Standard Household Base 50 Watt Incandescent Light Bulb Replacement with a 6 Watt LED, Warm White, 1012ww ($22),
both from Amazon.
Both were medium bright, perhaps about the same as a 30-watt incandescent bulb. One of these emits a pleasant Sun-colored light and the other emits a blueish light of about the same brightness. The label on the packaging of these two is (almost) identical, and there are no markings on the bulbs. Once taken out of the box it's not easy to say which box contained the blueish one and which contained the yellowish one :(
The bulbs are quite heavy -if you want to install them int one of those adjustable lamps with a spring-loaded arm, say Swing Arm Reading Lamp with Clamp in Chrome, good luck!
What irritates me about the way these are sold (and this applies to most new CFL types as well) is that the advertising or labeling usually does not make it clear how the light intensity compares with ordinary wattage-rated incandescent bulbs. I have a mental image of how bright a 60-watt bulb or a 100-watt bulb is. I don't know from lumen, lux, foot-candle or candela -and if I did, I'd be hard pressed to make a mental calculation from reading a specification label to translate that information into equivalence of old-fashioned incandescent watts.
I'd ask manufacturers and retailers to let us know how bright their bulb is, as marked by a traditional wattage rating! They ought to do that, at least until we've become accustomed to the new system. How difficult would it be? I'd have rated these products higher if the package and advertisement sated clearly and in bold print, that information, unambiguously.
