Pros: great price, flexible application
Best Uses: stills, studio, portrait
Describe Yourself: Photo Enthusiast
Using these bulbs in a photo booth application and they provide rich color on the subjects. Currently running 2 bulbs and they alloy me to shoot an f2.8 at 1/40th at about 1.5 meters through a diffuser. I will probably add a third bulb for a faster shutter. Cool running and low noise is also nice. Cannot comment on longevity as they have not been put through there paces time wise, but they deliver performance wise.
Bottom Line: Yes, I would recommend this to a friend
