• UVA light helps regulate behaviors such as feeding, diurnal movement, mating and similar activities. • UVB light allows the synthesis of vitamin D3, which helps to absorb calcium. • UVC light is not required for reptiles, but it can help kill bacteria. Note: Other wavelength LED’s are also available including 310 nm, 365 nm and 405 nm (UVA and UVB). Minimum buy and lead times will vary, but typically start at 25 pcs and 2-3 weeks.

The numbers that are used to measure UV light describe the activity level, or how energetic the photons in the light are, as well as the size of the wavelength. The most common form of UV radiation is sunlight, which produces UVA, UVB, and UVC rays. This page compare UVA vs UVB vs UVC and mentions difference between UVA, UVB and UVC ultraviolet ray types with respect to their frequency, wavelength and applications.

It falls between violet visible light and x-rays on the electromagnetic spectrum. UV is described as UVA, UVB, UVC, near ultraviolet, middle ultraviolet, and far ultraviolet, depending on its wavelength.

Wavelengths of visible light range from about 400 to 700 nm. Ultraviolet wavelengths range from 400nm to about 1nm and are beyond the range of visible light.

UVB light penetrates only the very surface or the epidermis of the skin. UVB is what causes the skin to produce vitamin D. Vitamin D is absolutely essential for health and wellbeing.

According to multiple sources (NASA, FDA, and others) here are the wavelengths of the UVA, UVB and UVC regions: UVA 400 nm - 320 nm UVB 320 nm - 290 nm UVC 290 nm - 100 nm Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. Like all forms of light on the EM spectrum, UV radiation is classified by wavelength. Wavelength describes the distance between the peaks in a series of waves. UVB rays have a short wavelength that It’s the product of a nuclear reaction at the sun’s core, and the radiation travels to earth via the sun’s rays. UV rays are classified according to wavelength: UVA (longest wavelength), UVB UVB light—or ultraviolet B—is a category of UV light characterized by a wavelength of 290-320 nm. UVB makes up less than 0.15% of natural sunlight. Is UVB Good for Plants?

UVB is generally defined as the wavelength range from 290-320nm, but it is the range between 290-305 nm that is most important. Sufficient irradiation within this narrow sub-band of the UVB range is a requirement for the photosynthesis of vitamin D3 in skin.

Because of this, UVB light is often cited as the source that causes sunburn. UVA has a wavelength of 380-315 nanometers and when contacting the skin can penetrate beyond the outer layer (epidermis) into a layer called the dermis.
