To the Editor:—
Kenneth Halprin, MD (199:841, 1967) says that "For less than $100 anyone can own a Wood's light." Your readers may purchase a purple 125-volt bulb and a handyman's cage, and be in business with an excellent filtered source of ultraviolet light for about $2.50. A darkroom helps.It is a remarkable tool, not only for diagnosis but also for confirmation of educated guesses. Problems of riboflavin utility, of vitamins A and B6, are brought to light in darkness! More expensive apparatus yields failures in the same areas in which the cheap one misses.Ah, the wonder of black light. And the help to the patient.
