Lamps are designed to last up to 2000 hours for the Essential/Original models, and up to 7000 hours for the SteriShoe+, depending on use and care. However, since UVC potency decreases overtime, we recommend replacing these lamps a minimum of every 2 years to ensure optimal germ-killing efficacy.
*Because UVC lamps degrade overtime, we do not recommend storing extra bulbs for future use. Replacement lamps cannot be returned or refunded for any reason. Lamps have a 60-day warranty period.
