1. A method of disinfecting surfaces comprising:
- using at least one ultraviolet emitting device to determine an amount of light energy necessary to disinfect various surfaces in an area containing said at least one ultraviolet emitting device, said ultraviolet emitting device having at least one ultraviolet bulb, based on the location of the surfaces relative to the at least one ultraviolet emitting device;
energizing the bulb of the at least one ultraviolet emitting device;
focusing light from the bulb into a concentrated beam using a reflector;
moving the beam to the various surfaces by rotating the reflector;
de-energizing the bulb of the at least one ultraviolet emitting device when the determined amount of light energy has disinfected the various surfaces.

Abstract
A system and method for disinfecting hard surfaces in an area such as a hospital room including a light source emitting UV light and a reflector mounted behind the light source for concentrating and directing the light toward a target. The light source and reflector rotate to direct the concentrated beam around a room, thereby making more efficient use of the energy being emitted.
