I’m really happy with this light. I use it as a fill light, and to add pops of background color in my photography. The only thing I’m upset about is that I don’t own more of them!BRIGHTNESSThis thing gets REALLY bright. When it’s on its brightest setting, don’t look directly at it, or you’ll see spots! The controls let you dial the brightness from 0-100. Yeah—that’s not a type-o. You can turn it on, then dial the brightness down to 0—which is effectively “off”—except the unit is still powered on. The light doesn’t get “hot”, but it gets warm when you crank it up to 100.COLORSYou can fine tune 360 individual colors using a dial. There’s a handy little rainbow spectrum chart on the back with printed numbers so you know what numbers to dial in for red (360), blue (240), green (120), and yellow (60).CONTROLSThe illuminated LCD screen on the back tells you the mode, color, brightness and saturation levels. The mode selector button is between the two dials.The dials don’t spin freely—they “click”. There’s no audible sound—you just feel the click when you turn the dials.The top dial controls brightness.The bottom dial controls things like color, saturation, etc.There’s little buttons in the center of each dial that toggle other settings for that dial. For example, the lower dial controls color (0-359). When you press the toggle, you then control color saturation (0-100).The power button is a (very stiff) recessed slider switch at the top of the light.MODESThere’s essentially 3 modes—1: Basic white light with adjustable the color temperature from yellowish (2500K) all the way up to crisp daylight white (8500K).2: Color (RGB) mode. Control brightness with the top dial, and RGB colors and saturation with the bottom dial. If “Blue” is a little bit TOO blue for you, just dial down the saturation, and it fades to your liking.3: Cool tricks, like firelight, lightning, TV flicker, police car red/blue strobes, and more.BATTERYIt has a built in, rechargeable battery. My unit lasts around 2-2 ½ hours at full power, a little longer if I tone it down. It takes a 1-2 hours to fully charge. The unit comes with a charging cable—not a brick. So if you don’t already have one, you’ll need a charging brick.BUILD QUALITYThis thing is solid. It’s plastic, but feels durable, and has a satisfying “heft” to it. It’s a little bigger than an iPhone SE, and smaller than an iPhone 12 Pro Max (see photos). The LED panel is covered with opaque plastic diffusion material, flush with the bezel. At the bottom of the unit is a rotatable metal arm with three ¼-twenty holes, and one hotshoe mount. I actually love this little arm—I use it as a kickstand, to position it vertically at a slight angle.CONCLUSIONThis is THE light to get at this price point. I actually plan to buy another one. Lower priced units don’t have as many LED bulbs (translation—they’re not as bright), and I couldn’t see how I'd benefit from higher priced brands.The only real gripe I have with this light is the sliding power switch. It’s stiff—you really have to mean it when you power it on and off. It’s recessed into the housing, making it fiddly to slide back and forth. I generally need to use two hands when powering on and off.I easily recommend this light. 5-stars all the way.
