Product Description
Case of 4 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.

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 light is called daylight 6000-6500)3) 12W LED lights go for as much as $90!4) Some bulbs are advertised as white but the chart on the back shows its yellow. Complete incompetence.Here is not what to avoid: all (harsh washed-out blue) daylight, and (yellow) soft white. While GE Reveal offers somewhat better clarity its still overpriced and quite yellow.Full spectrum (5000-5500) bulbs are a step-up but stores offer a very limited selection, like one! The Home Depot full 100w spectrum's beats the Lowe's Ott-Lite. The best compromise are the PAR38 indoor 23-27w 3500K reflector lights (which actually measure 4100K), especially for recessed kitchen spot lighting.On the LED front Sam's Club carries a 520 lumen, 4100K, 9 LED PAR38 reflector which has a easily noticeable smoother light spectrum. Interesting 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.Color temperature alone is not the sole basis to buy a bulb as a high CRI is also required. The Alzo's come in at 92, which is very high. Most manufactures do not even list this measurable figure (assume because its too low).Well gotta go as my wife wants one in her closet now, as shes hates the other fluorescent lights which cause eye-strain. Should I install a 45w and blow her away?

After having used these bulbs on several photographic applications, I have one word for them...FABULOUS!I have photographed real estate interiors, pets at a local animal shelter, and now food for a Pittsburgh area restaurant. The ALZO 45 watt has performed exactly "as advertised".The 5500K provides daylight color light that can be mixed with fill-flash and natural daylight, and one white balance setting does the job. Regarding white balance; you will have to experiment with the WB to find the right setting for your camera. Don't use the auto if you want the best results. On my Nikon D-40, I use the "cloudy +3" white balance for accurate color of my subject.The brightness of these bulbs, is as advertised, approximately equivalent to a 150 watt incandescent. I use two bulbs with reflectors and they are great for rooms up to about 20', but I may consider a pair of the higher watt ALZOs for larger rooms.Great product guys!

Incredible light and awesome brightness. Replaced this in the living room and the room looks so fresh and anew.(Update April 2nd 2009): Sorry. One of the bulbs is already gone. Thought this would last much longer than 3 months. I have to check into the hassle of replacing under warranty. It was used for about 4-5 hrs per day for 3 months.
