Ultraviolet light is used for many reasons ranging from insect control to germicidal sterilization. UV Lamps vary from long wave frequency to short wave frequency. This is usually measured in nm (nanometres). UV Lamp long wavelengths can rate at up to 450nm (approximately) while the short wavelengths rate below 100nm.
For example:
• Insect Zapper Lamps rate 369nm
• Blacklight Blue Lamps rate 352nm
• Germicidal Lamps rate 253.7nm
• Ozone uses both 253.7nm and 184nm.
It is therefore necesary to know the purpose of the lamp required to provide the most effective UV tube.
