No. The Lumin requires no replacement supplies whatsoever. The Lumin relies on a special germicidal UV-C bulb that is rated for 9,000 hours. Considering that the Lumin cycle is only 5 minutes, daily use of the device would require a total of 5.5 hours. In other words, the light source in the Lumin should easily outlast the life of the device and should not require changing. In the event, the bulb is damaged replacement bulbs are available.
