Our CAME-TV Perseus RGBDT Travel lights feature a unique yoke that allows them to fold flat, making them easy to stack in a Pelican 1510 and 1535 hard cases. The RGBDT LED lights have 2 groups of LED's for the color range of 2000K to 10000K and the Daylight group of LED's will illuminate with a high CRI of 98. By adding the DT group to the RGB LED we are able to maintain a high CRI throughout most of the output!
