PHOTO = No No

Photographer's and Videographers read:
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. In Adobe Lightroom 4, you need to compensate with Magenta by +22, under the White Balance meter (which actually requires 4900-5100)
So, in summery for all you photo/video guys... Don't buy these. Don't be a fool. They have major false advertising. Find a bulb with Tri-phospher coating or a coating with more admitted Magenta in it's cast. Magenta soaks into red/yellow tones of skin better than an ugly green color cast. Green is in NO hair, skin, and rarely makeup. This means, when you compensate with Green's opposite, Magenta, the photo becomes washed out and fuzzy. If you want any excessive colors, stick with excessive Blue or Amber (Red.) Unless you're taking photos of plants, don't buy bulbs that emit a green cast!
Where can you buy amber/magenta, also known as higher quality phospher bulbs? Well I've done my research and compared several. BlueMax is alright, but the repurpose Longstar CFL's, by putting a BlueMax sticker over them. If you want bulbs with +2 in-camera WB Shift green (Yes, they still have green, but ONLY visible when you over-saturate and image to an extreme.) Instead of +5-6 WB Shift Green, you should look into Longstar 23w or 55w bulbs. In comparison with Alzo digital here, the green spike is significantly less than half on Longstar (or BlueMax) and you can buy the 23w for $3-5 on some websites. (I'm not paid by either company, I'm just sick and tired of false advertising, even CRI's lie and NO ONE has the balls to post spectrum statistics from a light meter or machine.)
Tips: Also, for T8 and T5, look into GE cinema lamps, BlueMax lamps, and there is more more I "think" it is a phillips lamp that is 98 CRI but it's 24" instead of 48".
More tips: When buying CFLs, higher quality phospher (inner white coating) helps protect the integrity of a full spectrum light. Tri-Phospher or rare earth phosphers are best. Higher quality phosphers decrease luminosity (light output) but have less and less Green Cast (caused by Mercury vapor inside the glass lamps.) So if you're comparing two lights blindly online... DO NOT choose the one with higher lumen output... Why??? Because it's most likely got cheaper phosphers, so more light (green, mercury vapor based light) leaks out. Don't settle for a few lumens!!
DON'T FALL FOR FALSE MARKETING TACTITCS!
Do your research :-)
Hope this helps fellow artists maintain their quality and integrity.
