The LED-540 Professional Studio Lighting Kit from VidPro is a versatile, bi-color LED light panel for video and still-imaging applications. Featuring flicker-free dimming from 0 to 100%, and continuous transition from warm tungsten to cool daylight output, the LED-540 can easily match existing ambient light, blend in with other light sources, and be used as a subtle fill or a full main light source. The panel has fan-free, convection cooling for silent operation during video applications where sound recording is required. The LED-540 comes with 4-way barndoors that can shape the 120° beam spread for selective lighting. It's ready for worldwide use via its 110 to 240 VAC adapter, but it can also run on NP-F-type batteries in situations where AC power is unavailable.
