The FS-300B from Nanlite is an AC powered, bi-color LED monolight that was engineered to provide maximum output while maintaining an even light spread. A true, all-in-one monolight, the FS-300B employs a large LED array and a precision-engineered reflector to emit 38720 Lux of 5600K daylight-balanced light at 1 meter, and because it's bi-color it provides a CCT range of 2700K-6500K, all while maintaining a high CRI/TLCI of 96/97, ensuring accurate color rendition. Built-in Bluetooth allows you to directly control the FS-300B with the free NANLINK mobile app for iOS and Android, built-in 2.4G lets you control it with the WS-RC-C2 remote control (sold separately), or the WS-TB-1 Transmitter Box for more elaborate setups (also sold separately).
