Kelvin by Rift Labs 300W Full Color Spectrum RGBACL LED COB Studio Light (V-Mount)

The Kelvin by Rift Labs 300W Full Color Spectrum RGBACL LED COB Studio Light-V-Mount illuminates your professional setup with a multitude of creative possibilities. It can endure life on set and render amazing control and accuracy with light.

Broad Color Spectrum

Instead of using plain light, the Cantastoria Engine uses red, green, blue, amber, cyan, and lime. This gives rise to a kaleidoscope of perfectly mixed light. The light lives up to the accuracy and quality of Kelvin.

Meticulously Designed Tool

Kelvin ensures premium quality for every light by calibrating, testing, and verifying them by top engineers. Performance, quality, service life, and reliability have always been the priority for the company. The intricately designed LED chips ameliorate the quality and color range while complying with the industry SSI and TLCI standards.


The Epos 300 mixes red, green, blue, amber, cyan, and lime LEDs to create white light and a broad range of color light.​ RGBACL has a definite advantage over RGBWW. It offers a larger CCT range and can create more saturated colors with more output. RGBWW lights cannot produce saturated colors like yellow and usually do not have as much output when producing saturated colors. Another issue with RGBWW is the large drop-off in output at varying CCT settings.

Uncompromising Design and Build

The light uses durable aluminum housing as opposed to mediocre plastic. The 6-millimeter aluminum housing is structurally sound and ensures that heat is conducted away from the light. The case, structure, and finish are built from the same material, so the solidity and durability of the product are never in question. It guarantees an almost unbreakable build made to withstand wear and tear at the same time being recyclable. 


As it is battery-powered, you can have your set lit up as long as you want. Irrespective of whether it is A, B, or V-mount, its innovative technology renders it thermally efficient and perfectly structured. You can work off the grid without having to worry about power.

Unique Modes

The wide variety of effects offered by the product is CCT, HSI, RGB, Gel, and more. Illuminate your ideas through modes and colors to bring emotional depth to them. It assures the perfect balance of durable design and control. The accuracy of light brings you the best Kelvin has to offer.

Myriad Creative Possibilities

Apart from lines of code, Kelvin offers access to the Kelvin Narrator App that helps control your light. You can also use built-in lighting effects, presets, and gels. The light can be used to produce customized sequences without the trouble of switching devices. The Kelvin Narrator App also has tools to create the perfect blend of light you want. What you get is absolute control and precise light, without moving away from the monitor or camera.

Exquisite Engineering from Norway

The one-stop solution for creative lighting, Kelvin paves the way for new storytelling in cinema. Use the light in innovative ways for a lasting impression. The brand provides exemplary quality by ensuring that the parts are engineered, designed, and hand-assembled in the same building for uninterrupted perfection.
