F&V K4000s Bi-color led light

Unboxing the K4000s Bi-color led light from F&V. I got some additional help from my “guard” dog Naala in this unboxing video.

The Light itself is a nice combo of ease of use and portability. I really like that you can power it with V-mount batteries which makes it a contender for me to take out in the field. I will make a more in depth demonstration in a later episode.

Let’s look at what is inside the box….

The light

The K4000s a square led light with a nice form factor and easy to use controls at the back


K40002 F&V K4000s Bi-color led light

Here you see both of my K4000 lights together

Vmount battery adapter

A nice feature is the option to run the light on industry standard V-mount batteries which is a nice option for bloggers and run and gun Cinematographers alike. No need for a power outlet, just mount and shoot. Vmount battery is not included, I did however already have one and it worked like a charm.

Diffuser and accessories

A way to diffuse the light is always welcome, the kit comes with a option to mount a diffusor screen in front of the led light

K40004 F&V K4000s Bi-color led light

The kit comes with two power cords, UK and European.

Build Quality

I bought a couple of cheap lamps previously and I abandoned them immediately because the build quality for  attaching them to my lightgear such as C-stands was too poor . The F&V seems to hold up very nicely.
