At what temperature do tanning lamps generally produce the highest amount of ultraviolet light?

Tanning lamps are designed to emit ultraviolet (UV) light, which is the spectrum responsible for inducing tanning in the skin. The production of UV light is influenced significantly by the temperature of the tanning lamps. Generally, the highest output of UV light occurs when the temperature is within a specific range.

The correct choice indicates that tanning lamps produce the highest amount of ultraviolet light when the temperature is between 90 to 110 degrees Fahrenheit. This range is optimal for the lamps to reach their peak operational efficiency. At these temperatures, the chemical processes within the lamps that generate UV radiation are maximized, allowing the tanning session to be more effective.

Different temperature ranges mentioned in the other options typically do not provide enough heat to support the chemical reaction necessary for optimal UV light production, or they exceed the temperature where the lamps can function safely and effectively. By understanding this relationship between temperature and UV output, those in the tanning industry can better manage lamp usage and provide clients with effective tanning experiences.
