I now have 6 lights with nearly identical function and size to this light, so I will refer to my experiences with those lights in comparison. This is a small battery power LED (bi-color and full RGB) with probably the coolest design of any lights I have, and very easy modes of operation. This version of the light is stealth black on black on the rear, so if someone tries to use it the first time, it's tough to read what each knob does, but looks cool and doesn't have the bright white paint if it happens to be in the shot. I do wish the scrolling of the knobs made for faster action (takes a while to scroll up to 100% or down to 1% for instance) and I feel like the brightness is not quite as strong as some of my other similar lights, but the color temp measures very accurate, and the battery seems to last really well. I pictured the LEDs at 4000K with 1% brightness in order to show the amount of LEDs and arrangement. I have owned MANY K&F products over the years from tons of ND and VND filters, tripod, etc and these lights fit the same high end build quality as the other K&F products. There are two magents in the back that you can slightly see through the transparent backing. They hold REALLY well on nice flat metal surfaces, but even on a round pole, the can hold if positioned properly. It comes with 1/4 20 screw holes on the top and bottom, and a 1/4 20 cold shoe mount is included. Worth noting that there is not a cold shoe slot built into the light itself (for stacking lights) so you would need a 1/4 20 to 1/4 20 screw to connect two together. Not a deal breaker but I often connect my lights during storage to help keep them all together. Overall performance is great, and the built quality and style (if that matters) can't be beat. These are nice-looking lights!
