Product Description

Full spectrum light bulbs for daylight balanced lighting, energy star compliant, long-lasting at cir. 8,000 hours *)with 2800 Lumens output; low energy consumption, good for treating S.A.D. (Seasonal Affective Disorder), photo studio lights, or starting plant growth. These are Compact Fluorescent Light (CFL) bulbs. Fits all medium-base E27/E26 sockets, but this is a large bulb that might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed, see ALZO 10" harp, ASIN B003SZCUZ2. Dimensions: L: 7"; W (Diameter): 3"; Length socket base to top of ballast: 3"; W (diameter) of socket: 1". Also available as a 15W bulb, see ASIN B0089MIH8I. *) ALZO CFL bulb life is based on the bulb in an open air upright orientation. When ALZO bulbs are installed in fixtures that lack adequate ventilation, the life of the bulb will be reduced. If an ALZO CFL bulb is installed in an overhead recessed light fixture with the bulb glass below the base, the life of the bulb will be greatly reduced. ALZO warranty for all CFL bulbs is 30 days.

It fits into a standard light socket.
James Sibley
Its "white" light, which is a very different color to the incandescent bulbs we are used to, illuminates the room extremely well, making nighttime easier on the eyes.
Derek Kind
Full spectrum lights are very helpful in this regard, so I can get "sunlight" even in the middle of the night.

I am a painter of the 'visual art' variety. I use these bulbs in my artist lamps and they are wonderful. Gone are the days of painting at night then discovering in the light of day that my colors are all wrong! Also they are great for lighting my paintings for photographing them. These bulbs are really pretty tough...I knocked a lamp over and the bulb did not break,whew!

This light is beautiful! Reading under its light is an amazing experience. My text is clear, soft and very easy on the eyes. Its beautiful pure white light is made clear when you place it next to other so called white and full spectrum lights. Next to this they all have a yellow tone to one extent or another. It took me 10 expensive light purchases before I found this. Save your money and buy this one first then you can compare it to others and be ready to be shocked.

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.

I often don't get as much sunlight as I should due to screwy sleep patterns. Full spectrum lights are very helpful in this regard, so I can get "sunlight" even in the middle of the night.

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.

I bought the ALZO 45-Watt Photo CFL Full Spectrum Light Bulb to start my own poor-man's DIY photography lighting set-up. Before purchase, I read all the specs and liked the 5500 Kelvin rating. I also read all of the customer reviews and paid special attention to comments referring to its size. Everyone who says this light bulb is big is correct, and I've uploaded some pictures to prove it. It's significantly longer and wider than the bulbs you'll find at Walmart or Home Depot, and the particular bulb I own has a wide base that flares out abruptly which prevents it from fitting in a standard clamp light reflector, which, incidentally, prevents it from making proper contact inside the light socket. So for now I'm using the clamp lights without reflectors until I can find something suitable. Bear that in mind, since it may also prevent it from working with or fitting some standard light fixtures, as is clearly stated in the product description.

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.

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.
