The KNOWLED F400Bi Bi-Colour LED Light Panel from Godox is a 400W professional lighting solution designed for film, television, and studio applications. This slim, versatile panel delivers adjustable colour temperatures from 2700K to 8500K, providing accurate, high-quality light with a CRI and TLCI of 96. Measuring 121 x 63 cm and foldable for portability, the F400Bi is ideal for on-location shoots or flexible studio setups.
Brightness is fully stepless from 0 to 100%, with four dimming curves—linear, S-curve, exponential, and logarithmic—allowing precise control for any scene. Eleven preprogrammed special effects enhance creative lighting possibilities. The F400Bi supports multiple control methods, including local adjustments via the controller, DMX512, LumenRadio CRMX, built-in 2.4 GHz wireless control, and Bluetooth via the Godox Light App. It is compatible with the optional Godox RC-R9 Remote for added convenience.
Built to withstand demanding environments, the F400Bi is rated IP65 for dust and water resistance, protecting both the LED beads and controller. The light comes complete with a controller, connector and power cables, an X-bracket with adapter holder for mounting, a softbox for diffusion, and two carrying bags for the panel and accessories, offering professional convenience and portability for any production.
