Lighting
Lighting is an essential utility in a health care facility. The operating room requires special
attention to lighting because of the small-scale delicate tasks that must be performed.
Although, the choice of a surgical light is subjective, several characteristics must be
addressed. The criteria include light intensity, light color, focusing capability and range,
degree of shadow production, heat production and dissipation, choice of mounting, lamp
head maneuverability, and ease of cleaning (Bronzino, 1992).
