The FL400 Flexible LED 3 Set with V-Mount Battery Plates from Cineroid contains all the components you'll need to get up and running with this unique light source. The kit includes three flexible bi-color FL400 LED mats and X-Brackets to convert them to a rigid panel and stand mount them. Also included are three controllers to adjust brightness and color, three AC adapters, three diffuser sets, three 9.8' extension cables, and a carry bag. These lights have battery plates that allow them to run on V-Mount batteries when mains power is unavailable.
