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).
Finally, the F&V R-300 (LED Ring Light), K4000, and K4000S 1x1 LED Light Panels are ready to ship! I personally have placed a pre-order for (3) of the R-300 LED Ring lights mainly for portability and the simple option of using inexpensive Sony batteries, and plan to use them mainly off-camera on light stands. I've been eagerly anticipating these lights since my pre-order, so excited to hear it's finally shipped.
The R-300 LED Ring Light is available in two different options, one with a 15mm Rod support and one with an L-Bracket Mount. According to F&V the 15mm rod support has been delayed in its transit, so customers will initially receive the ring light and then will be shipped the rail mount in about 2-3 weeks following. For all customers that have already pre-ordered the R300 w/ 15mm rod support, F&V plans to gift them the optional Milk Diffusion Filter for being patient and to show appreciation for their business.

R-300 LED Video Ring Light
The K-4000 and K400S 1X1 LED Video Lights are also available on the site. I've seen these lights at the last PhotoPlus NY show and was very impressed by the build quality and light output. You can purchase the lights individually, or check out the current specials for (3) 1x1 LED Lights in a kit starting at just $1050 ($350/each). That's very competitive pricing even against more popular LED lights on the market. You can find the K-4000/K4000S light panels at the product page (Click Here).
