I have a bunch of different compact RGB lights, from very bright with built-in fans, to very compact and not terribly bright. This is a pretty good budget compromise. It's reasonably bright, but doesn't have a distracting fan. It has a real display with an easy-to-use interface that tells you what your brightness settings and color temperatures are, and it has effects settings, which I never use.The user interface is pretty easy to use. I like that it has a sliding power on switch, so it's more difficult to turn on accidentally, although I think the two-stage power up future of some of my other battery powered lights is even more resistant to accidental energizing of the lights.There's a mode selector, as well as a thumb wheel to scroll through the brightness, color temperature, or RGB settings. The display is pretty easy to use. The labeling of the individual buttons is hard to read, especially in low light, which is annoying. It's not too difficult to memorize the button functions, but it would be nice for them to be labeled well enough to be read in low light.Although the light listed as having CRI above 95%, I wasn't able to verify that. The readings I got were under 95%, and very depending on the color temperature settings.I got a CRI of 93 with the light set to 5700 k, and a meter reading of 5730k and 215 lux on my 350UV at 1 meter.Overall this is a cute little light. It is very lightweight and compact. Build quality is okay, but the detents on the thumb wheel are a bit soft and not very high quality feeling.
