Here's an overview of the new F&V K4000 LED Studio Light Panels along with a few samples at the end showing how it compares to a common ARRI 650W Fresnel. The unique offset filter mount on the K4000s allow better diffusion and eliminates multi-shadow issues that are common with LED lights.

Description: A lightweight and portable studio solution, integrating our newest technology in synchronous lighting, expandability, and power LEDs. The perfect mobile studio lighting solution. Available in daylight and bi-color models. The new K4000 Daylight Studio Panel light sports 400 pure color power LEDs, offering 2860 Lux @ 1 meter in a self-contained 1'x1' unit. Carefully selected LEDs are put through multiple tests and evaluations to ensure perfect color balance and diode matching. This offers an absolute pure color consistency between LEDs, and a clean daylight calibrated color (5600K).

The K4000 LED panels are also available in Bi-Color for adjustable color temperature from 3200K-5600K. Individually these lights are more expensive than the common 600, 900, or 1200 LED panels but the 3 Piece Studio Kit (found here) that includes a nice travel bag brings them down to about $330/each.

It's not the same... it's different designs. No surprise there.
But the deal with the LEDs is that for interviews with a nice tight crop you can move the lights in close... LEDs are NOT meant to stand far away from the talent.
@Svem... don't know why you would ever compare those two. They are completely different tools. Of course the LED flat panel will NEVER have the same throw and adjustability as a fresnel lamp... that should be common knowledge.
Tungsten lights still have the best color rendition and they serve a different purpose than LEDs do now. I would rather bring as decent LED panel to a hit and run interview than a hot tungsten lamp that now only heats up the room but also has to cool down afterwards.
But in terms of light quality, the 650w fresnel is way better.
It's a compromise... or wait forever till the price of the Arri L7 comes down 😉
Who knows, maybe LEP lights will be available next year if we are lucky, now that's a throw you don't wan to miss.
@sam - You can try to use a manual white balance if you want to warm it up. Instead of using the Daylight setting or 5600K in your camera, change it to a manual 6000K. Try changing the settings and things will get warmer or cooler.
i have the F&V R3 video light, and I find it too white for my taste. noticing here that compared to the arri its also whitish. wonder if they gel with a CTO making them warmer. similar to david's post above i have a few chinese redheads that work great, but they are a power drain.
@Davide - I don't think the output is similar. The Arri will probably throw further than the LED.
hi there, i shoot loads of videoclip, i'm actually just concerned that a full band (4-5 pieces) get enough light, usually i go with 3 800w chinese red heads (2 in the back and one in the front) but i'd really like to switch to LEDS. do you think their output is similar?
@vaitor - Here is the link: https://www.fvlighting.com/k4000-led-studio-panel-3-light-kit.html/
i cant find the 3pcs with the bag in the picture above... could you update the link? really interested to get it as a kit... wondering if you could attach stands to the bag too, would be a great "mobile" solution for interviews
So how does this compare to the Arri 650W in terms of maximum light output and light throw?
I have one and the "raised" milk filter works great, it softens the image perfectly and the end result is pretty similar to any fluorescent source.
