Background: Ultraviolet (UV) light is used ... bactericidal effect of UVB light. In this study, we examined the bactericidal effects of UVB-light emitting diode (LED) irradiation on oral bacteria ...

Full Spectrum Full spectrum devices include the UVA and UVB ranges, and meet general illumination criteria. They simulate the full-spectrum range of natural light, and include a balance of the ...

Both ultraviolet A (UVA) and ultraviolet B (UVB) light have documented efficacy for treating MF (Abe, Ohnishi, Kan, & Ishikawa, 2003; Herrmann et al., 1995; Querfeld et al., 2005) and response is ...

While addressable LED strips are all the rage, [Mike] from [mikeselectricstuff] has been working on an installation using the more basic two-wire strips that are simply controlled via PWM dimming.

Looking to sterilize something? Give it a good blast of the old UV-C. Ultraviolet radiation in the shortest wavelength band breaks down DNA and RNA, so it’s a great way to kill off any nasties ...

UVA rays also contribute to the risk of skin cancer. The Earth’s atmosphere shields us from most Ultraviolet B rays. The amount of UVB rays that reach the Earth’s surface depend on latitude ...

Ultraviolet light, also known as UV light, is a form of energy traveling through space. It is a form of electromagnetic radiation with a wavelength shorter (100 - 400 nanometers) than that of visible ...

The sun's ultraviolet radiation can cause skin cancer and premature aging. Here's how the UV Index can help in sunny places ...
