NEEWER CB300B 320W Bi Color Continuous LED Video Light

This is now my most powerful continuous light by far. If I want to bring it down to the power of my other lights, there is a novel feature on this called 'Booster' that puts the unit into a low power mode. Everything seems to operate the same either way but the Brightness control's range using the app slider or the back buttons/dial work in the lower 60W so you have finer adjustments possible with Booster off.In practice I usually have the CB300 with Booster ON. However another benefit of Booster OFF is that with the lower output limit, the unit shuts off the fan and can use the heat sinks to silently dissipate heat.The Neewer smartphone app connected easily enough. I just found that for this CB300 it was not that well thought out because when on the screen with touch sliders for Brightness and Color Temperature, there were several extra taps to get into another screen just for the sake of selecting Booster ON/OFF. It would make so much more sense to have that showing on the previous screen - there is lots of room for it. The app allows saving favourite pairs of Brightness & Temperature to recall them later quite quickly.Using only the physical controls I was able to get everything I typically use just by looking at the labels and watching the indicators on the display. I was soon able to keep looking at the camera subject and reach over to feel the buttons and dial to adjust while I kept my concentration on the subject. The main power switch is not on the back. It is tucked on the bottom curve of the main body, offset a little bit to the right of the AC cord connector. There is even a big, bright blue label "POWER >>>>>" wrapping around the can to direct a user to the power switch. Amusing to see for the first time and useful under the circumstances.The metal bracket to mount the CB300 to a stand is large and lengthy. The receiver for a light stand spigot has holes for both vertical and horizontal connection to a spigot. The swivel points are large and the grip is helped by large diameter toothed faces digging into thick rubbery disks. The tightening knob is similarly large diameter so the light is not going to slip and tilt.The release for the Bowens mount reflector is a bright blue slider that operates with very little effort or noise. My variety of Bowens mount items mounted and released with no hitches. The included reflector has a cut out for an umbrella shaft. The body has a metal block where the umbrella shaft would get locked into place with a thumb screw. It's solidly built.The included Neewer carrying case is a piece of work all on its own. The hidden construction as far as I can determine is a semi-rigid wrap around tub of plastic. So the entire well of the case is almost like a camper cooler in effect. The lid also contains a semi rigid panel. There are bulbous feet with this case that seem to give enough clearance that you could put the case down on a wet parking lot and the case itself is not going to touch the water. The CB300 and its essential parts take up all the room inside the case so as big as the case appears, it's dedicated to protecting the light, not for stuffing in other accessories.
