The Chroma Connect LED Light is a lightweight, highly portable RGB LED light that easily connects other accessories to your image capture device.

This LED light is easy to take just about anywhere. And thanks to its 3 cold shoes, the Chroma CL33B becomes an important junction for connecting other important accessories too.

Charging the internal battery is simple. Use the included USB-C cable and a standard USB-A port (5V at 1A to 3A) in your home, car, or office to recharge the light's internal battery. Want to run the light continuously? Just leave it connected to a USB charger and it will run for as long as you need.

The CL33B is an amazingly advanced light in a tiny package. It has 3 modes: RGB, Bi-Color, and Special Effect. When set to RGB mode this light has 360 colors (hues) as well as saturation control for each color with a range of 0 - 100%. Bi-Color mode has an extended color temperature range of 2,500K to 8,500K. And 20 unique scenes can be accessed in Special Effects mode. 

Quality of light is extremely important and with a TLCI rating of 98+ the Chroma CL33B is an outstanding performer.
