To find UV lamps for applications requiring ultraviolet light, select a category below.
See a definition of ultraviolet light at the bottom of this page.

	UV-A Blacklight Bulbs Low-Pressure Mercury Arc Lamps UVA wavelength range: 315nm - 400nm Peak: 352nm Used for: photosensitization and photochemical reaction applications and insect traps. Output includes visible light.
	UV-A Blacklight Blue Bulbs Low-Pressure Mercury Arc Lamps UVA wavelength range: 315nm - 400nm Peak: 352nm or 368nm Used for: tests, inspections, examinations, stage illumination. Deep blue filter glass absorbs visible light, transmits near UV.
	UV-B Bulbs Low-Pressure Mercury Arc Lamps UVB wavelength range: 280nm - 360nm Peak: 306nm Used for: inspection, analysis, testing (UV resistance of paints, plastics, rubbers), dermatology phototherapy
	UV-C Germicidal & Ozone Bulbs Low-Pressure Mercury Arc Lamps Germicidal Peak: 253.7nm Germicidal plus Ozone Peaks: 253.7nm and 185nm Used for: sterilization of surfaces, materials, air and water

What is Ultraviolet Light?

Ultraviolet light is invisible to the human eye. It is part of the electromagnetic spectrum that lies beyond the purple range of the visible spectrum. The ultraviolet (or UV) spectrum has wavelengths between 100 and 400 nanometers (nm). The UV spectrum is further divided into wavelength ranges named UVA, UVB, UVC:

UVA: sun tanning, testing, inspection, insect traps, stage effects, blacklight, phototherapy* (315-400nm)
UVB: sun burning, inspection, analysis, testing, phototherapy* (280-360nm)
UVC: germicidal (253.7nm), ozone producing (185nm)

*Phototherapy for treatment of skin diseases uses bulbs emitting in the UVA and UVB spectral range. There is also non-UV phototherapy for treatment of infant jaundice. These bulbs, "bili lights", are low or non-UV emitting fluorescent or halogen sources with strong blue light in the visible spectral range of 425-475nm.

Warning: UV radiation is harmful to skin and eyes.
