The market taxonomy of Household Ultraviolet Disinfection Lamp by type classifies products into germicidal UV‑C lamps, UV‑LED lamps, and portable UV wands, each reflecting distinct technology pathways and cost structures. Germicidal UV‑C lamps, which dominate roughly 55 % of unit shipments, rely on low‑pressure mercury vapor to emit 254 nm radiation and are typically integrated into fixed fixtures for continuous operation. Their prevalence is anchored in proven efficacy against a broad spectrum of pathogens, supporting larger household installations such as water‑treatment units and whole‑home air purifiers. UV‑LED lamps, representing about 30 % of the market, employ semiconductor‑based emitters that offer instant on/off cycling, reduced energy consumption, and safer handling, making them suitable for compact countertop and appliance‑integrated designs. Portable UV wands, accounting for the remaining 15 %, are battery‑powered handheld devices used for spot‑treating high‑touch surfaces. Although their penetration is lower, the wand segment is expanding rapidly due to consumer preference for on‑demand disinfection and the declining cost of high‑output LEDs. This type‑level segmentation clarifies how technology adoption and price elasticity drive overall market growth.
