The Lume Cube Video Conference Lighting Kit is designed to attach to your computer monitor to provide illumination for your webcam video conferences. This light offers a 3200 to 5600K adjustable color temperature for different environments, a 96+ CRI color accuracy, and 1 to 100% brightness adjustment.
The light runs for approximately 1.2 hours at full brightness and 2.2 hours at half brightness on a built-in battery, which is rechargeable via an included USB cable that plugs into the light. An LCD on the rear of the light displays color temperature and brightness settings plus the remaining battery runtime.
This kit consists of the Lume Cube Panel Mini pocket-size LED light and a compact Suction Cup Mount that attaches the light to your monitor. The light has an aluminum housing and is only about 3.5 x 2", and it features a 1/4"-20 mounting thread on the bottom and the side so that you can mount it horizontally or vertically. The suction cup provides a matching 1/4"-20 screw.
