The Light Storm LS300X LED Light Kit from Aputure is the first Aputure light to go beyond traditional bi-color lighting by utilizing the expanded vari-white CCT range of 2700-6500K, providing warmer tungsten tones and cooler than daylight whites. The brilliant light can be dimmed from a potent main light to a subtle, nuanced fill light, flicker free across the dimming range.The Controller Box attached to the LS300X head with a 9.8-foot head extension cable, so adjusting settings is effortless regardless of where the light is set. The self-regulating , multi-voltage controller also operates using single or dual V-mount batteries, suitable for lighting in remote locations.
