I had seen these popping up here and there, and wanted to give it a shot and MAN, I am blown away!
This thing is SO bright! I had my Pocket Camera set at 200 ISO, and a I couldn't get any higher than like T5.6 before blowing out! This this is WAY brighter than I expected it to be, but also has some amazing color!
My only gripe, which isn't much of one at all, but it does feel a little bit fragile, even though it is 100% tougher than Kino Bulbs, I would make sure to mount it properly and safely just to be sure!
I haven't tried the dimming, but I assume it's amazing! I will definitely be buying more of these in the future...Many More....in the Near Future!
