The Cosmo-Light (later rebranded as Color-Therm) is a device, originally manufactured and sold by Fred Gerkey, a Kansan chiropractor, consisting of a wooden box holding "tubes for producing colored lights similar to the so-called neon lights, together with the electrical connections needed to operate them," which was marketed as an instrument for chromotherapeutic use. According to Gerkey's advertising materials, the device would be used to expose patients to light of a curative frequency, claiming such exposures would be effective in the treatment of afflictions stemming from the "liver, eyes, female trouble, asthma, nervousness and sinus trouble."
