How long are UV lamps good for?
CaluTech products use UV-C germicidal lamps which operate at a wavelength of 253.7 nanometers, the germicidal wavelength of light which kills germs, and can last as long as 3 years. However, no UV lamp should be used for more than 12 months without replacing the UV lamp. Although they still light up after 12 months they do not produce the UVC germicidal light they did when they were new. 36W replacements are only $22.99 each, not $40 or $80 each like other companies (we don’t mark them up). Replacement 18W lamps are $22.49. It is a very cost effective UV air purifier. We recommend annual changes of the UV lamps for maximum ultraviolet air sterilization.
