One of the primary differences between ozone and ultraviolet (UV) lamps involves use. Ultraviolet lamps emit light that is invisible to the human eye. Water purification systems in swimming pools, drinking water and fish-farming facilities commonly use UV lamps. Using UV instead of chlorine reduces toxic buildup. Tanning beds also use UV lamps. Ozone rays are toxic to human skin. Common uses for ozone lamps include hotel room sanitation and odor removal from locations damaged by fire and flooding.
Bulbs used in ultraviolet lamps come in a variety of shapes and sizes. Cylindrical, tubed or U-shaped bulbs are required, depending on the lamp model. UV bulbs have double- or single-side connections available in a single, double or four-pin style. Ozone lamps work by beaming ultraviolet light through an electrical charge inside a special chamber. Because of the complex assembly, ozone units can be quite large and tend to vary less in size.
Ultraviolet lamp supporters indicate the device is cheaper than its ozone counterpart. Upfront costs may be lower for UV lamps, but bulbs need to be replaced at more frequent intervals than ozone production units on ozone lamps. UV bulbs have an average lifespan of 8,000 to 12,000 hours. The devices also require more operating power. Ozone lamps have lifespans ranging from 9,000 to 45,000 hours. Devices run on a fraction of the power required to operate similarly sized UV lamps.
The possibility of overdosing on ultraviolet rays is minimal, and the lamps pose few risks to human health. Ozone lamps leak on occasion. The material is undetectable, and the Environmental Protection Agency noted respiratory ailments in individuals exposed to high ozone levels. Specially trained technicians perform maintenance on ozone lamps. Bulbs for ultraviolet units are easily accessible for consumer purchase. Potential risks are another set of factors that marks significant differences between ozone and ultraviolet lamps.
