bought two of these so I can play around with creative lighting for both work and personal projects. I wanted to use LEDs instead of gels (with flashes or hot lights) but wasn't ready to make a big purchase during this uncomfortable pandemic time when my working options are much less robust. These little lights turned out really great! First of all, they are recharged, which is already a huge advantage over more devices that require batteries. While I don't know how they'll perform long-term (since you can't open up and replace the battery you're using), they weren't really expensive, so I'd say they'll probably survive long enough to make the buy one good value for money. They can also be used during charging in a pinch. They're extremely light and easily mounts to anything that accepts a standard 1/4" screw mount or cold shoe mount (clamps are cheap to find thanks to everyone who uses Go-Pro that mounts to various things are). The settings are easy to change, and you can adjust both the color value (in the white space or in the RGB space) and the brightness, and the screen on the back makes it easy to confirm the settings you want to use. I have attached two pictures taken with my iPhone as a test when I first received and charged it. Both photos are of the same toy which is solid black with gold flames. The lights are positioned rear left/front right and the color version has a blue/fuchsia contrast. The original shot is just a cool white light.
