We carry a complete selection of UV lamps for every brand and model. If you know the actual part number of your UV light we can assist you. Most UV system manufacturers use a lamp or bulb made by a UV light bulb manufacturer and do not make their own lamps. All ultra violet Lamps must be replaced every 12 months since the light wave output changes over time, even though they may LOOK like they are working since the lamp may still light up.
