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). The COB light source of the FS-300B features a built-in glass cap for long-term protection. Powerful, Even Light Output The bi-color FS-300B LED Monolight from Nanlite utilizes a larger LED array than most COB LED monolights to deliver up to 38720 Lux of 5600K light at 1 meter with the included reflector as well as a smooth and even light spread with no hotspots when used in a softbox. Bi-Color with Advanced Features The FS-300B has an adjustable CCT range of 2700K-6500K, giving you the full flexibility of bi-color. It also has advanced features from the top-of-the-line Forza 720B: Maximum Output Mode (which supplies the full power of the light), and Constant Output Mode (which maintains a constant intensity across the CCT range). Built-in App Control and In-Body Cooling FS-Series lights feature Bluetooth for direct control with the free NANLINK app for iOS and Android, and 2.4G for more control options. They have an integrated design with the control unit, power adapter, and lamp body all in one compact fixture, making them more lightweight with effective heat dissipation. Bowens Style Light Modifier Mount By utilizing the near-universal Bowens style light modifier mount and incorporating an umbrella holder into the yolk, the FS-300B is compatible with a massive selection of light modifiers. Including, but not limited to, Nanlite's line of fresnels, softboxes, and umbrellas. Practical Effects With customizable pre-programmed special effects in a simple-to-master menu system, the FS-300B makes it easy to imitate lighting scenarios that can otherwise be tricky to recreate. At the touch of a button, you can simulate 12 different practical lighting effects: CCT Loop, INT Loop, Flash, Pulse, Storm, TV, Paparazzi, Candle/Fire, Bad Bulb, Fireworks, Explosion, and Welding.
