The impact of ultraviolet radiation on human health has implications for the risks and benefits of sun exposure and is also implicated in issues such as fluorescent lamps and health. Getting too much sun exposure can be harmful, but in moderation, sun exposure is beneficial. UV light (specifically, UVB) causes the body to produce vitamin D, which is essential for life. Humans need some UV radiation to maintain adequate vitamin D levels. According to the World Health Organiz… 

UVB: [ ul″trah-vi´o-let ] denoting electromagnetic radiation of wavelength shorter than that of the violet end of the spectrum, having wavelengths of 4–400 nanometers. ultraviolet A (UVA) ultraviolet radiation with wavelengths between 320 and 400 nm, comprising over 99 per cent of such radiation that reaches the surface of the earth. ...

Every type of reptile or amphibian has slightly different needs but a general rule of thumb is to keep the UVB light/heat source on for 12 hours and off for 12 hours, a programmable power center can manage the time rotation. 

Narrowband UVB is the most common form of phototherapy used to treat skin diseases. "Narrowband" refers to a specific wavelength of ultraviolet ( UV) radiation, 311 to 312 nm. UVB phototherapy was formerly provided as a broadband source (290 to 320 nm). The narrowband range of UV radiation has proved to be the most beneficial component of ... 

UVB rays are responsible for producing sunburn. The UVB rays also play the greatest role in causing skin cancers, including the deadly black mole form of skin cancer (malignant melanoma). UVA rays also play a role in skin cancer formation. In addition, the UVA rays penetrate more deeply into the skin and play a greater role in premature skin ...
