Sun-Kraft Ultraviolet Ray Health Lamp
From Kook Science
The Sun-Kraft Wireless Cold-Quartz Ultraviolet Ray Health Lamp is a cold quartz mercury-vapour lamp, invented by Frank Furedy and originally sold through Sun-Kraft, Inc., for use in ultraviolet light therapy (which you certainly could've figured out from the name of the product). Bathing in the radiation of the Sun-Kraft UV lamp was promoted as a treatment for "head colds, discomfort caused by sinus pains, rheumatism, arthritis, and neuritis," in addition to "clearing up skin ailments, such as eczema, acne, athlete's foot, and ring worm," and promoting healthy skin and hair. As with many similar products making such lofty claims about its efficacy, the Sun-Kraft health lamp was subject to FDA misbranding charges in the late 1940s.
