What to know before buying

Listing details to confirm

Coverage claims conflict: the listing states both up to 150m² and a top coverage of 80 m². The 18W, 4200V, 360 NM wavelength, 8500-hour lamp-life and IPX4 claims are listing specifications, not independently confirmed. Customer feedback is mixed on effectiveness and brightness and raises durability concerns. Follow the stated guidance to clean weekly and allow the unit to dry before use.
