Ra is pronounced "raw" and is the name of the sun god of ancient Egypt. He was believed to carry the sun across the sky. Wearing the Kogalla Ra light is like carrying a piece of the sun.
The name of the light has since evolved to the UltRA Trail Light. UltRA is short for "ultimate RA" as it is the ultimate light for use on the trail or anywhere that you need more light than you get from a flashlight or headlamp. And it's no coincidence that the first major market to embrace this light was the ultra trail running community. It's kind of a homage to those athletes that run in these ultra marathon events on the trails. And yet it's the ultimate light to everyone who needs a lot of light.
