The 5500K ALZO bulbs are the closest thing I've found to actual sunlight. I've seen reviews with proper colorimeter readings and such, but not having access to such gear, my basic test is to compare the color to natural sunlight through a window on a sunny day. The color these bulbs put out is quite close to that. I've also tried some photographic tests, calibrated with a gray card, and these bulbs produce the best results of the full spectrum bulbs I've tried.
The main downside with the 45W bulbs is that they are quite large, particularly being quite long at 7". You may need a larger harp, or a larger shade, or to relocate a standing lamp so the bulb can stick out but not be in your field of view. And for some lamps and most overhead fixtures, 45W bulbs won't fit at all. It's a limitation of the technology, of course, so any manufacturer's 45W CFL is going to be similarly sized. Due to the size issue, I only have one of these, at my desk, and a few 23W and 27W full spectrum bulbs elsewhere; it was easier and cheaper to use multiple smaller CFLs in most cases.
Keep in mind that your brain expects light to get yellower as it dims, part of the reason that "normal" bulbs are usually 2700 - 3000K and thus much more yellow. While these look like natural sunlight on a sunny day, at night the pure white light feels a bit sterile and clinical at first.Read more ›
I like this tone so much that I have removed the long florescent tubes in my kitchen and changed the base to accept standard light bulbs so I can use this instead. Over time I will replace every light in my house with this exact light. At night if you lay under the light and close your eyes, you can almost trick your mind into thinking its soft sunlight... Simply wonderful for those that live in 25C temps every day.
As far as light quality is concerned, I'm pretty ecstatic. These things are bright. What also appeals to me is the very slight hint of blue they produce. It's a pleasant change to the standard "yellow" color of most light bulbs, and it seems to help make objects look more crisp and sharp. The pictures I've taken using these bulbs are bright and clear. Granted they're probably not as powerful as professional-grade bulbs, but they'll do in a pinch if you're on a tight budget. I find their light is also easier on the eyes than I anticipated, so I would also recommend them for general use.
A number of reviewers have complained about the higher-pitched "hum" the bulbs emit. Since I'm only using them for photography, it doesn't bother me at all. Even then, the sound is pretty faint in my opinion, and I tend to keep things quiet.Read more ›
I purchased these cfl's as an upgrade to default 23w 5500k, 82 cri, major green spike bulbs. I noticed, rather obviously when against a white/grey wall, these bulbs still have the "eerie" green cast they claim to not have. Let's put this into perspective.
I ordered these 45w full spectrum's from Alzo, expecting minimal green color spike. When compared to all readily-available box-store cfl's, yes they are better. When it comes to photo/video, when rendering in post production having too much green makes for bad final results. Why? Because the camera often compensates on Blue/Amber (for kelvin temps, white balance.) Rarely does green or magenta ever come into effect in outdoor photography, via the WB +/- Shift bracketing you can opt to do in camera, that is. It's always Red (Amber) and Blue (Cyan.)
Now, you've heard why I don't like these bulbs, for photography. Let me enlighten you on what intensity of dislike I have. It's not hate, it's just spite, for their false advertising. Don't be a sucker.
In camera, meaning White Balance / Kelvin Temperature / WB Shift +/-, Alzo Digital lights require 4900-5100 in-camera-reality, for a 5500k label. Also, they have a major green spike. Why do I say major? Well, a camera can WB Bracket inbetween different White Balances. Such as Daylight + Amber (Red) for more warmth in daytime. You can add up to 9 colors, moving 9 up on red is basically like going from Daylight to Cloudy. (More red compensates for more blue from no direct sun.)
Alzo Digital 45w CFL's have anywhere from 5-6 WB Brackets of green. Technically, this means it has 45-66% MORE geeen in it's spectrum of light it pushes on a subject.Read more ›
