Technical Description of the Knowled MG4K G-mount Bi-color COB Light with Paper Box

The Knowled MG4K is a professional-grade bi-color LED light designed for high-output film, broadcast, and studio applications. Despite its compact and lightweight form factor, it delivers light output comparable to a traditional 4K HMI source while consuming only half the power. The lighting unit incorporates an advanced COB (chip-on-board) LED with a small 63mm emitting area, achieving industry-leading optical efficiency and luminous efficacy.

Featuring a versatile color temperature range from 2800K to 10,000K, the MG4K enables precise color tuning with a green/magenta adjustment range of ±100%. This flexibility allows for seamless matching with different light sources and creative lighting effects, supported by a dimming system capable of 0.1% increments for smooth brightness control. An advanced heat dissipation system improves cooling efficiency by approximately 67%, which ensures stable performance during prolonged use and extends the overall service life of the fixture.

Its design is built around the patented G-Mount ecosystem, offering compatibility with over 16 professional modifiers. These include reflectors, Fresnel lenses, Beamlights, projection attachments, softboxes, Liteflow units, and adjustable diffusion accessories, giving cinematographers and technicians extensive control over light shaping and distribution. The light body weighs roughly 10 kilograms, and with the yoke attached, it weighs about 12.5 kilograms, making it easier to rig, transport, and position on set compared to much heavier traditional HMIs.
