Product Description

Case of 4 Full Spectrum 27W Light Bulbs that imitate daylight, are energy star compliant, and have a long life of circa 10,000 hours *) with 1300 Lumens output, 120V; low energy consumption, good for treating Seasonal Affective Disorder S.A.D., or for starting plant growth.
These are Compact Fluorescent Light (CFL) bulbs that fit all medium-base E27/E26 sockets, but the large bulb size might create a fit problem with standard lamp harps of household light fixtures; a larger lamp harp is needed, see ASIN below.

Dimensions: L: 6.5 in; W (Diameter): 2.25 in; Length socket base to top of ballast: 2.75 in; W (diameter) of socket: 1 in. Also available as a 15W bulb, see ASIN below.

Important:
*) 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.

Combine With:
• ASIN B0035LTIZE; 9 in lamp harp
• ASIN B0089MIH8I; 15W Joyous Light Full Spectrum bulb

I am an engineer who has been completely disgusted with the home lighting situation. There are no standards and many misstatements and counterdictions at the stores. I own a Minolta flash meter which accurately measures a lights color temperature. I've tried the bulb technology at Walmart, Sams Club Home Depot and Lowes. The most glaring examples:
1) yellow light is called soft white (2700)
2) very blue washed-out color light is called daylight (6000-6500)
3) Low lumen (400-600 lumens) LED lights go for as much as $90!
4) Some bulbs are advertised as white but the chart on the back shows its yellow. Go Figure!

Here are the bulbs to avoid: all (harsh washed-out blue) daylight, and (yellow) soft white. The GE Reveal offers somewhat better clarity, but is overpriced and quite yellow.

Full spectrum (5000-5500) bulbs are a step-up but stores offer a very limited selection. The Home Depot full 100w spectrum's beats the Lowe's Ott-Lite.

On the LED front Sam's Club carries a 520 lumen, 4100K, 9 LED PAR38 reflector which has a easily noticeable smoother light spectrum. Great for the one light on in the kitchen in the evening. The equivalent $70 LED lights at the hardware store are hardly a bargain, as the Sam's is $20! However its Color Retention index (CRI)is only 74.

The best of all are lights are these 5500K Alzo's. I've installed a 45w in the kitchen pantry and the color of the food boxes really pop. Food looks like it does in the magazines. The clarity is first rate (however 27w should be sufficient). They are the reference to which others are to be compared. My wife has not complained even when they are on at night-time. This is a first.
Skin tones in the bathroom look very natural. A first again.

I'm a painter - of canvases, not houses. I need an indoor light source that's as much like natural daylight as possible, so my color choices will be accurate and consistent, and not "surprising" when viewed somewhere other than my studio.

Before ordering the ALZO 4-pack of 27-watt bulbs I called the ALZO company, which is actually a manufacturer of photography-related products. I spoke with Joseph (or Yosef?) there, who is a professional photographer with decades of experience. He answered my questions with real expertise and I felt entirely confident in ordering the ALZO bulbs from Amazon.

My Amazon order arrived with the usual Amazon efficiency. The bulbs are individually boxed, with all four boxes packed inside an outer box. They are LARGER than you might expect, but my application is utilitarian, so that's not a problem. See the dimensioned illustration on the Amazon product page.

The light is BRIGHT(!) and very WHITE(!) and for me, the 27W size is all I need (though I may find use for the 35W version eventually). According to Joseph, 5,500 degrees Kelvin is as close as you can get to natural daylight (5,600K) and what I see supports that statement well. I expect to use two bulbs when painting; that's a mere 54 watts of electricity for a LOT of balanced, bright "daylight". The energy savings are much appreciated.

As long as the large bulb size does not present a problem, I suggest you buy this four pack. The price per bulb is MUCH lower than that of competing bulbs and the quality seems good. A Good Value, sez I.

BONUS: As I understand it, these bulbs also provide the type of light used to overcome S.A.D.

These things give off a lot of bright white light with a slightly bluish tint. The chromatic variance off of true white is subtle however most people do not realize how used to the strong yellow tones of the average incandescent or CFL bulb. While science has a lot to say about the positive benefits of using a full spectrum light bulb, choosing this particular bulb requires a keen awareness of your use.

These lights are sturdy, are a little bit heavier than your average CFL, and are about a coil and a half too long for most residential lighting fixtures which were sized for the former incandescent bulbs.

ALZO is a great choice, if you need a smaller one, look for one with a slightly smaller watt rating, and also count the coils. This bulb would be an excellent choice for larger rooms and lights where more light is necessary - and where the mount supports its longer length.

I bought these bulbs mainly based on the review by 'NotaSecondTime'. Now that I've received them and had them on for a little while, I can state unequivocally that he was 100% correct: these are the best bulbs I've ever bought.

Obviously, since I just got these, I can't speak to longevity; but after warming up for about several minutes, these bulbs bathed my office in the most natural light short of actual sunlight coming through the windows. (NOTE: while the bulbs do take a few minutes to *completely* warm up, these bulbs are very bright when you first throw the switch; not like other CFLs that sometimes don't even turn on for a second after the switch is thrown.)

If you're used to incandescent bulbs or other CFLs in the 2700k-spectrum, you're probably used to everything having a yellow tint. After a week with these lights, though, you'll never go back. [I tried the GE 61355 Reveal 26-Watt Indoor Floodlight R40, which was also supposed to be more-natural light, but they are yellow too.]

My only complaint is that these lights don't come encased in a standard bulb enclosure (so that they look like any other R40 flush light bulb), and that they can't be used on dimmer switches. That would make these bulbs perfect. But I didn't deduct a star for those two issues because they're not defects - just features I wish they had.

Make sure when you first turn these on for the first time that you leave them on for at least a solid hour to break them in. Otherwise, you might shorten the bulb's life or introduce periodic mild buzzing for the first 5-10 minutes they're on. My bulbs are silent, and all four that I ordered arrived in working condition.
