Built on the foundation of the popular LS C300d, Aputure's Light Storm LS C300d Mark II LED Light Kit with V-Mount Battery Plate is an enhanced version with 20% more power, refined features, and advanced connectivity. Aputure uses Chip on Board (COB) technology to produce a 5500K color temperature, with power consumption of just 350W, while outputting 3500 lux of light with an efficient reflector at a distance of 9.8'. In addition to power efficiency, this fixture also has a CRI/TLCI rating of 96, indicating accuracy in color rendering. When combined with the optional Fresnel 2X, the 300d Mark II can produce up to 80,000 lux, approaching the luminance of a 575W HMI! And as always, the 5500K-balanced 300d Mark II maintains very accurate color fidelity with CRI/TLCI ratings of 96+.
