This bright LED pumps out 48,000 lux at .5m with the included reflector or 142,000 lux at .5m with a Fresnel mount. Aputure says that’s roughly equal to what you’d get from a 2k tungsten or 400w HMI light. The LS 300d has a color temperature of 5500k and a CRI of 95+ and a TLCI (Television Lighting Consistency Index) score of 96+ which, like CRI, is scored out of 100. The lightweight LED weighs in at 4.6 pounds despite its aircraft-grade aluminum body. The light is controlled via a control box that is separate from the body of the light. It can also be controlled wirelessly via a 2.4GHz remote with a range of 150m. The 300d draws power from an AC outlet or from two V-mount batteries. It uses a Bowens mount to accept a wide variety of modifiers and is fan cooled so it shouldn’t melt your softboxes and umbrellas.
