Good lord, I had no idea so much light could come out of a single light socket. You will be utterly amazed by this thing. It's like having daylight in the middle of the room; I seriously sometimes forget that it's nighttime.

Apparently, this bulb is intended for photographers. However, if you are looking for a replacement for sunlight in your home, this is it. I have this bulb in the middle of the ceiling in a 14x16 room, and it lights it up like daytime. It's so much easier on the eyes, and doesn't have the glare like a normal bulb.

This light is AMAZING. I bought this light for my large collection of indoor tropical plants, and surprisingly it not only lit up all my plants, but my entire room. As everyone has mentioned here the size of this bulb is by far extra large, but also the amount of light it emits is impressive.

I had purchased a LED light along with this bulb since LED lights do not provide any warmth. Even though this single bulb has managed to light up all my 30 plants I still used the LED light considering the benefits of using LED. Either way being able to proved so many plants indoors at such a low price is unreal.

This is a perfect choice for those areas that never have enough light in the evening. You know when you are trying to read something or you are trying to work on something like connecting wires to electronics & it is difficult to read the labeling on the back of the PC or stereo so you have to use a flashlight? Not with this bulb! Flashlights are embarrassed in this bulb's prescence. My flashlights are now in therapy to recover from their disappointment & inadequecy in this room now. (I am serious.)

Living 1 block from a small airport requires me to choose wisely when to turn this light on so that small aircraft don't think it is an airport beacon and try to land in our yard. Oh, you don't believe that, do you? Well, this thing is WONDERFULLY BRIGHT. It is quiet with no hum. It is in a floor lamp with a lamp shade in a small bedroom that is used as a den for the PC, Xbox 360, & toy room for our grandchildren. Colors are correct & everything is illuminated JUST RIGHT. They play with toys that they can now see as they should. I leave it off early in the morning when it is dark outside when I first wake up. "My eyes, my eyes!" However, it is perfect to light everything up the rest of the day and evening. Exactly what I wanted. (If I get a second one I can duplicate the effect of having the Sun in this room without all the heat.) Be sure to get a 14" lamp harp which I could only find at [...]

I bought these for my house to keep it bright and cheerful, but, as other reviewers state, it is HUGE. WAY to big for any light socket in your house, unless you want people laughing at you. LOL However, I put them in my garage, as I work on my car out there a lot, and it is SOOOO bright in there now! I love it! No more doing things in the dark. The light is pure white and looks just like sunlight. You almost expect to see a huge hole in the room where the sun is sneaking in. :) I'd recommend these for any socket where puting in a bulb that is approx. 11-12 inches long is not going to be a problem.

The light surprised me when i got it in the mail it was about 3x the size i thought it would be. The light is a very pure white. I have a small room i put it in and it lights it up nicely and not too much even though it is pretty bright. I've gotten used to the light and its created a nice clean atmosphere to the room i really like it and recommend it to any prospective buyer.

I was preapred for the size and heat that other reviewers discusses in their posts. I would never have puchased this bulb in the fist place if I knew how much it was going to flicker and the amount of noise it made. Def. not for in home casual use.

The picture doesn't do justice to the size of this light. Despite being a CFL this is not going to fit into most standard light fixtures. The ballast is extremely wide. I found a place for it in my light arrangement, and it is quite bright and does a great job. Don't expect to be able to screw it in just anywhere, though - this is definitely a grow light and it needs a grow light fixture.

The product works well and produces a very bright white light. It is longer than a standard bulb but fits in the normal socket.

ALZO's full spectrum CFLs are the best CFLs I can find online, with CRI=91 and 5500K.
For photography lighting source, we care about two things, color temperature and color rendering index (CRI).
It's relatively easy to find a CFL satisfying color temperature requirement, but hard to find ones with good CRI.
Usually, CFL's CRI ranges between 60~82, the higher the better. I compare the pictures taken with a CRI=82 CFL and this one, the improvement is quite noticeable. In fact, the result produced by this CFL is very close to that of incandescent illumination (with the highest possible CRI=100). Because of a whiter color (5500K) and lower input power, this CFL is in some sense even better than an incandescent bulb.
One drawback is the huge size of it. Make sure it can fit in your lighting kit before buying it. Another one is the thin bubble wrap in the packaging, it may not provide sufficient protection.
