Positioned as a compact yet powerful point-source lighting solution, the Godox KNOWLED MG4K Bi-Colour LED Monolight Travel Kit delivers 2000W of cinema-grade output in a smaller form factor than the MG6K, without compromising performance. Designed for high-end film, broadcast, and studio environments, the MG4K combines exceptional brightness, precision colour control, and professional connectivity in a rugged, production-ready system.
Part of Godox’s advanced KNOWLED MG series, the MG4K features G-Mount compatibility and an IP65-rated housing, making it suitable for both studio and demanding on-location use. Its separate controller design allows the light head to be rigged overhead with ease while maintaining convenient access to controls. An upgraded fan cooling system ensures stable operation and long-term reliability.
Despite its compact design, the MG4K incorporates Godox’s smallest emitting light source at just 6.1cm, maximizing optical efficiency and brightness. The result is a cinema-quality LED fixture that exceeds the output of traditional 4K HMI lights, while consuming significantly less power. A robust flight case is included for secure transport and storage.des flight case for transport
Precision Bi-Colour Lighting
The KNOWLED MG4K offers a broad 2800–10,000K colour temperature range, allowing seamless matching with ambient light, other fixtures, or creative warm-to-cool lighting setups. With 0.1% precision dimming, accurate colour reproduction, and professional-grade consistency, the MG4K is ideally suited for TV studios, filmmakers, and lighting designers who demand total control over light quality.
Exceptional Brightness
When paired with the included 30° reflector, the MG4K delivers up to 640,000 lux at 1 m at 5600K. For even more concentrated output, the fixture supports an optional 15° reflector, enabling highly directional, high-intensity lighting. Godox notes that the MG4K achieves this performance using approximately half the energy of a conventional 4K HMI fixture.
Intuitive & Advanced Control
The MG4K is designed to integrate seamlessly into professional workflows with multiple control options:
menRadio CRMX for wireEthernet support for network-based lighting systems
These options allow fast, precise adjustments on set, whether operating independently or within complex lighting rigs.
Consistent Performance & Thermal Management
An upgraded fan cooling system ensures efficient heat dissipation, protecting the LED engine and maintaining consistent output during extended shooting sessions. This advanced thermal management supports stable performance in both controlled studios and challenging environments.
G-Mount Compatibility
The MG4K uses the Godox G-Mount, providing access to a growing ecosystem of 16 dedicated modifiers. Compatible accessories include reflectors, Fresnel lenses, BeamLight systems, projection attachments, softboxes, the LiteFlow system, and more—giving lighting professionals full creative control over beam shaping and output.
AC Power & IP65 Weather Resistance
Designed primarily for AC-powered environments, the MG4K includes both AC and DC power cords. Its IP65-rated construction protects against dust, rain, water splashes, fog, and other harsh conditions, making it reliable for outdoor and location shoots. The 10kg (light head only) design offers class-leading output in a compact, manageable formyi
