UV-B lights are lights that emit an ultraviolet light spectrum with wavelengths ranging from 290-320 nanometers. This spectrum is also commonly called the biological spectrum because of the sensitivity of the human body to light like wavelength. UV-B rays do not overly camouflage the skin, compared to UV-A lamps used in tanning beds.

Treating skin diseases
The main diseases treated with UV-B lamps are psoriasis, lichen planus and atopic dermatitis (eczema), Vitiligo (skin loss) and some other skin diseases.
There are thousands of dermatology clinics around the world that treat skin diseases with UV-B lamps. Many people who suffer from psoriasis or other skin diseases have their own UV-B lamps for home care. A small lamp is used to treat limited areas of the skin, while a full body cabin is available in clinics and hospitals.
Overexposure to UV-B rays can burn the skin, so the lighting time should be adjusted by the timer that turns off the light.

Increase vitamin D3
When the skin is exposed to UV-B rays, the cholesterol in the skin is converted to vitamin D3. In general, the skin does not require a lot of UV-B energy to produce vitamin D3, and 15 minutes of strong sunlight every day is usually considered enough.
In Northern European countries especially in winter when rare sunlight, pregnant women may receive UVB rays in the clinic to ensure that their babies have sufficient amounts of vitamin D3 at birth.
Animals need UV-B light to produce strong vitamin D3 and bone. The zoo has UV-B lamps for reptiles kept in the room. Reptile keepers in the home environment can buy UV-B/UVA lights that emit from a pet store to provide their reptiles with the amount of UVB/UVA needed to produce vitamin D3. Such lights are Creature World or Repti Glo branded and used for a period of 10-12 hours per day to provide the necessary exposure. These lights simulate the solar spectrum and thus produce most of the visible light and very small amounts of UV-B rays, such as the sun.
Cancer risk
UV-B treatment for treating skin diseases (psoriasis, vitiligo, atopic apathy, etc.) is given in very low doses. Treatment takes only a few minutes.
The maximum dose of UV-B broadband is 0.5 Joules per treatment. The maximum dose for narrowband UV-B is 3 Joules per treatment. This low dose does not increase the risk of skin cancer and UV-B phototherapy remains a very safe treatment. The study mentions ten years of phototherapy experience at Yonsei Medical Center has not revealed any cases of malignancy in the skin.
Too much ultraviolet UV radiation from unwanted wavelengths can cause direct DNA damage, sunburn, and skin cancer. In contrast to UV-B exposure given at low doses, it was found that UV-A rays increase the risk of skin cancer due to the problematic wavelengths and are therefore given in much higher doses.
