How often do the UVC lamps need to be changed?
The actual life of a UVC light is 10 – 12,000 hours. The useful life is 8-9,000 hours. UV output is measured with a radiometer. Typically the light is changed annually — ideally in spring or early summer to provide optimal output during the peak air-conditioning season. How much energy does a UVC device use? Each unit consumes very little energy. Normally the energy cost to power each fixture is under $.12 per day. Top Is ozone an air purifier or a contaminant? Ozone is being marketed by some as an air purifier, often in conjunction with UVC. It is true that UVC will produce ozone at low frequencies. The UVC devices that IAQ – Energy Solutions handles attenuate all frequencies below 200 nanometers so that no ozone is produced. According to the U.S. Food and Drug Administration: “Ozone, to be effective as a bactericide or deodorizer, must be present in concentrations far greater than that which can be safely tolerated by man or other animals.” According to the U.S. Environmental Protec
