Add Full Color Spectrum To Your Lighting Creations

Gone are the days where a light was just a light. The Cantastoria Engine utilises Red, Green, Blue, Amber, Cyan and Lime. The result is an infinite color palette of precisely mixed light. The color accuracy and light quality are in a league of its own.


An Ultra-Precision Tool

Every light is calibrated, tested and verified by one of Kelvin’s engineers.

Our focus on performance, quality, service life and reliability of our products is achieved by the way we make and test every single light.

Our innovative LED chips are meticulously designed to not only improve quality and color range, but are mathematically proven to simulate the industry SSI and TLCI standards.


The Advantage Of RGBACL

The Epos 300 doesn’t use any white LEDs. Instead, we are mixing Red Green Blue Amber Cyan Lime LEDs to produce white light and any color you can imagine.

The advantage RGBACL has over RGBWW is that it is capable of giving you a larger CCT range and it can produce more saturated colors with more output. RGBWW lights tend to struggle to create saturated colors like yellow and they dont always have as much output when generating saturated colors. They can also have a large drop-off in output at different CCT settings.”

Designed and Built Without Compromise

Our 6mm solid aluminum housing exceeds structural requirements, conducts heat better away from the light, and it is stronger than creaky plastic. One material as case, structure and finish removes complexity, yet adds strength and robustness without compromise.

Everything you could ever need, no distractions. Made to be handled hard. Harder, than a traditional tungsten work horse. 

Almost unbreakable, yet highly recyclable.


A Battery Powered Super Light

Anywhere you choose to take it.

Made to run off batteries, whether it’s A, B- or V-mount – the professional light quality illuminates your set, all day long, whether you are on or off the grid.

Our unique design delivers better thermal efficiency, a sturdy construction so you can light the action longer.

Peace of mind when you are on set, wherever it may be.


All The Modes You Need To Light Your Story

CCT, HSI, RGB, Gel effects and more.

Use colors and modes to create emotional stories through the language of light.

“You’ll never use another gel again.”
