The Weeylite RB9 Professional Photography Fill Light features 108 LEDs—36 RGB, 36 tungsten, and 36 daylight—in a lightweight, compact form. Select from 360 colors in RGB mode or adjust the color temperature from 2500 to 8500K. The light is dimmable from 100% brightness to 0%. The fixture has a lightweight aluminum chassis, and it features one top-mounted on/off button and four control buttons on the side. The built-in OLED screen on the back displays the mode number and battery gauge, as well as associated info such as color temperature, RGB hue and saturation, or effect setting. There are several built-in color and light effects such as pulse, waterfall, and alarm lights.

\r\nThe RB9 is powered by an integrated 3000mAh lithium-ion battery that can be charged to full in approximately three hours using the included USB Type-C cable. At full brightness, the light lasts approximately two hours. A power bank mode allows you to use the light as a power bank, but this requires a separately available cable. The light fixture can be mounted using its 1/4'-20 mounting threads or mounted onto a camera's cold shoe with the included adapter.
