I don't like my lights yellow, I don't like them blue. With that in mind, I bought just one of this CFL to check out. It has just a shade of that warm white (5000K instead of 5500K) to it which makes it ideal to use in a residential environment. Pictures taken using a digital camera under this light have come out nice looking - not bluish or yellowish. The difference in color rendering is also clear. So far the lamp hasn't had a high pitch whine which some of the other CFL's have been prone to.
The one thing keeping me from rating this lamp higher is slow startup. Takes at least a couple of minutes for the lamp to reach full brightness. For a 40 watt lamp, it also seems to emit slightly less lumens - but I gladly accept that for better quality light (Quality over Quantity).
Another thing to keep in mind that the lamp is fairly large (tall). This is after all a 40W CFL. Not all fixtures will accept this light w/o the lamp sticking out.
Beats the junk they sell in warehouse stores..

I have little experience with CFL bulbs. In my home office I like to use full spectrum bulbs, and so I decided to try this product when my other bulbs gave out. My previous experience with CFL bulbs has been that they tend to be not very bright, so I bought these thinking that it would provide me with a bright workspace--which I like. After putting 3 of them in a fixture and turning the fixture on, I feel like I am working on the sun. Or perhaps on a surgery table in an ER. To try to look directly at the fixture (which has exposed bulbs) actually hurts my eyes the light is so bright. I'll continue to use these bulbs, but I'm going to switch out to just 1 of these along with 2 at a lower wattage.

The form factor of the bulb provides a very large base as was noted by another reviewer. Overall the size of this bulb is much larger than a traditonal format bulb.

I am not giving the bulb a 5 star review because of the sound emitted by the bulb when illuminated. Some may not notice it, and it's the kind of thing that over time I expect one would get used to, but the bulb emits a very high pitched "electric sound" when illuminated. Perhaps with only one bulb it would not be noticed, but when 3 of them are combined in a light fixture less than 6 feet away, you definitely get noise that can be annoying.

Many people do not consider the fact that a simple choice of lighting can change the feeling you have in your own home. Soft white bulbs just make a room seem dull and uninteresting, while a full spectrum bulb really brightens things up and creates a more uplifting environment. These bulbs are high quality, give off a lot of light, and warm right up. The only downside to the bulb is if you have sensitive ears you may hear a slight electric buzz. Overall great product.
