Important: ALZO CFL bulb life is based on the bulb in an open-air upright orientation. When 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.

Light Bulb ALZO 45 watt Photo CFL 5500K

Pros: Great daylight color
Cons: Light penetration less than I expected
Best Uses: Up close static photography
Describe Yourself: Occasional Photographer
Good packaging. Slight buzz from 1 bulb but I only use them for photo lighting so it is not an issue. At a rated 170W equivalent I was a little disappointed by the spread of light. Seems to drop off very quickly. Apparently this is typical of CFL's. Even with a claimed 340W (2 bulbs) I needed them quite close to the subject. I use the lights to photograph items I list on eBay. Although I have a keen interest in photography I have not used 'proper' lighting before. Not using a softbox or umbrella at this time.
Bottom Line: Yes, I would recommend this to a friend

Great Photographic Lighting

Pros: Perfect daylight bulbs; Low wattage; Well built; Inexpensive
Cons: Large size
Best Uses: Photography/Video lighting
Describe Yourself: Professional Photographer/Videographer
Can't say enough good about the 55ook bulbs. I shoot commercial photography for YouTube videos and a lot of food-shoots for restaurants, and these ALZO bulbs always make my work look its best. Now, lighting technique is still very important, and you must adjust your camera to the proper white balance for this lighting, but with the 5500k's I can mix some window light, and even add some fill-flash, and the colors all seem to match with my white balance setting. The bulbs are very large at the base, so make sure your fixtures can support them, or there's an optional extender ALZO sells that can help there. Great job guys!!
Bottom Line: Yes, I would recommend this to a friend

Purchased these bulbs through Amazon to experiment with a continuous lighting source. Shipped to me very quickly, cost was nominal. All four worked when I tried them. Checked them with my camera at 5500k and white was white. Can't ask for anything more, for the price. Satisfied with seller, satisfied with product.
Bottom Line: Yes, I would recommend this to a friend
