I purchased this primarily for product photography and it works great. The ability to blend the two colour temps to obtain the perfect colour balance is great. Light output is good. The only reason I gave it 4 stars is the tilt adjustment part of the mount. When tilting, it is very hard to move, even when it's loosened completely it's very tough to actually tilt and it feels like it's going to break. I worried it will break at some point. Doesn't seem to be very strong plastic. I'll see how it goes.
