What are the Different Types
of Ultraviolet Bulbs?
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
