Dermatologic Application of High Pressure Mercury Lamp in Use for Illumination / 대한피부과학회지

In search of suitable long wave ultraviolet light source which is not available in Korea for photopatch tests and for the treatment of vitiligo and psoriasis. We picked high pressure mercury lamp used for out-door illumination for evaluation. On spectrophotometric examinatio., it is disclosed that the lamp emitted enough long wave ultraviolet rays for our purpose. It requires 6 minutes for photopatch tests at 50 cm for 200 watt bulb. It is recommanded that the commercially available cheap out door illumination lamp should be used for dermatological parposes until equivalent medical equipment is available. The construction and principle of mercury vapor lamp is reviewed.
