CFL 11 Watt E27 UV Blacklight Lamp

UV light bulbs are fluorescent tubes with a dark blue or purple filter to remove other parts of the spectrum and leave just UVA light. UV (ultraviolet) light bulbs are often referred to as black light bulbs, or BLB (blacklight blue) bulbs. UV lights feature small wavelengths that are measured in nanometers (nm).

UV lamps are cost-effectively used for water purification in water reclamation, waste water, drinking water, industrial and commercial process water, pool and spa, aquaculture and life sciences applications.

UV radiation is classified into three primary types: ultraviolet A (UVA), ultraviolet B (UVB), and ultraviolet C (UVC), based on their wavelengths.
