Lume Cube's Bi-Color LED Light and Power Bank is an ultra-slim LED panel that also provides power bank functionality to charge your smartphone. Because of its slim and lightweight design, it can just as comfortably be used with a smartphone as with a traditional camera for photo, video, and vlogging applications. It mounts via a 1/4'-20 threaded hole on the bottom. A 1/4'-20 to shoe mount adapter is included for attaching the light directly to your camera or camera/smartphone cage.

So compact, when not in use, the light can even be kept in your pocket. It features a 3200 to 5600K adjustable color temperature and has a high CRI of 96+ for accurate color rendering. Brightness is adjustable in a range of 5 to 100% in increments of 5%. The maximum brightness output is 1600 lux when measured at a distance of 1.6'.

An intuitive LCD on the rear displays various parameters, such as the color temperature setting, and also confirms the remaining runtime after every change in brightness. At 100% brightness, the light runs for approximately 90 minutes, and at 50% for three hours. It runs on a built-in lithium-polymer battery with a 4040mAh capacity.

The battery is rechargeable via a supplied micro-USB charging cable. There's also a USB Type-C charging port for use with optional USB Type-C cables. Next to this port is a mini-USB port that allows for power bank functionality. Using a supplied mini-USB to USB adapter, you can connect the light to your smartphone via a matching USB cable, not included, and charge the phone as you would with a standard USB power bank. The power bank port provides an output of 5V, 2A.

All the control buttons are discreetly located on the side of the light, and the USB ports are even more discreetly on the bottom.
