This is a step above most of the little camera lights that are out there. It's got two key features that really stand out. The first is the display on the back. It shows you exactly where you're at with regard to brightness percentage and color temperature. I don't know if the measurements are accurate or not, but at minimum this kind of display makes reproducing a certain light easy. I can note what temperature and brightness I used and easily get back to it on another shot. The second is the adjustment knob. Rather than a button you have to press over and over, there's a large, easy-to-use knob. It's as if the people that built this actually use it.
Aside from those features, there's the nice touch of connections. There's two screw mounts, so you can have the knobs pointing whichever way is most convenient. There's also two pairs of holes for a strap.
There's a load of effects modes like flickering candle, TV screen blue, fireworks, strobe lights, etc. It's a way to provide some off-screen lighting for a video. That part isn't really my cup of tea, but it's easy enough to skip over because it has a dedicated slot on the mode knob.
Overall, I really like this. It's now my favorite photo fill light.
