How long are UV lamps good for and what are the specs?
CaluTech products use UV-C germicidal lamps which operate at a wavelength of 253.7 nanometers (the pure germicidal wavelength of light). Each lamp is under warranty for 30 days, and most replacements are under $25 each, not $40 or $80 each like other companies. It is a very cost effective UV air purifier. The lamps are known to operate for as long as 3 years. We recommend annual changes of the UV lamps for maximum ultraviolet air sterilization.
