Before buying this light, I researched the hell out of this type of light in the Web. I compared each and every feature, and this one won over all the other brands hands down.
It has everything one could want and then some. Logical, smart, very sturdy build, convenient controls, beautiful and powerful light, especially for such a rather small source, but don't let that fool you. The power of this thing is tremendous, quick and easy to control.
I am a 40 year NY City professional still life Advertising photographer and I always worked with the most powerful (6000 ws) Broncolor lights, and I really wish I would have had these lights back then.
