About Kelvin Epos 300 300W RGBACL LED COB Studio Light with Rolling Case, B-Mount

Kelvin by Rift Labs Epos 300.

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.

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.
