Sunlamps

Sunlamps are electric devices that emit light and ultraviolet radiation in an effort to simulate sunlight. They range from compact consumer units intended for home tanning or light therapy to larger professional systems used in clinics. Some sunlamps are designed primarily to produce UV radiation for tanning, while others are intended for medical phototherapy or research and are used under supervision to treat certain skin conditions or mood disorders.

In tanning-oriented sunlamps, the emitted light typically includes UVA and UVB radiation to stimulate melanin production in the skin. This can result in a tan but also increases the risk of skin damage with excessive exposure. UV exposure from sunlamps can also help the body produce vitamin D, although the amount varies with skin type and exposure duration.

Medical or therapeutic sunlamps function as UV phototherapy units. They deliver controlled doses of UV light, often narrowband UVB or broadband UVA, to treat conditions such as psoriasis, eczema, vitiligo, or other skin disorders. These devices are usually used under clinical supervision to minimize risks and tailor treatment to the patient.

Safety and regulation are major considerations with sunlamps. UV exposure carries risks of skin cancer, premature aging, and eye injury, so protective eyewear and adherence to recommended exposure limits are essential. Regulations governing the availability and use of sunlamps vary by country and region, with many places restricting or curbing use, especially for minors or unsupervised consumers. Users should follow manufacturer instructions and seek professional guidance when considering therapeutic use.
