The K4000 Plus utilizes the F&V Plus LED. The F&V Plus LED has an accurate color temperature and has a color rendering of CRI 90 +/- 1.0. At a 60° beam angle, 400 LEDs produce a bright, even beam of light which is perfect for shoots in the studio or on location. The K4000 Plus comes packaged with the noteworthy Milk Diffusion Filter which creates a soft, glamorous light. The Milk Diffusion Filter now utilizes a snap-in, quick-release mounting system. This new mounting system will work in unison with additional accessories, giving users the ability to stack modifiers on top of one another. This secure mounting system allows the light to be rigged sideways or upside down without the possibility of accessories falling or sliding out.
The K4000 Plus has an expansion port which allows for installation of the SmartSync Control Circuit (SCC) as well as a DMX512 Module. The SCC module allows you to daisy chain multiple units together via CAT5 cables. When chained together, any light modified in the chain will cause all the other lights to dim in unison. The DMX512 Module allows for control of the lights with standard DMX512 dimmer boards.
