We've been using these Ikan 500 LED lights alot on daylight run-and-gun shoots and have been very pleased with the performance. So pleased that I picked up a couple of knockoffs on eBay. And to my surprise they look very very similar and perform exactly the same. I mean exactly the same right down to the exact stickers on the inside of the barndoors, and the same plastic film that you have to remove before use. Hmmmm.
