If you are like me, I constantly struggle between packing the bare minimum amount of gear I need and ensuring that I have what I might need when I get to the site. Often a small light such as this is exactly what you might need to help illuminate your subject should your destination prove to be a "low light" challenge. This K&F fixture is small enough to almost not notice you have it, yet provides just enough lumens (close up) to help your subject pop. Color temp and brightness are adjustable and it has a bevy of effects should you need them. For me the effects are superfluous but as a small key light in a pinch, this has great value. The display provides both color temp and level which is handy for reference. BrightIt also works well as a practical light for illuminating background objects. Its small size lets you hide it behind objects to give your background a bit of color. Two 1/4"-20 threaded inserts (top & bottom) provide adequate attachment options.

The only downside is that the rotary switch is a bit easy to turn on when storing/traveling with the device. It would have been good to have had a recessed push button to avoid accidental turn-on. Such a lightweight and small device I think I will leave it permanently in my travel case.
