How often should UV odor-control lamps be replaced?

Lamp effectiveness declines with use, and a lamp that still lights may no longer control odors adequately; replace it according to the service interval, accumulated runtime and actual performance. Avoid touching the lamp surface and keep the ballast connections secure. Checklist: Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records. Do not compare unit price alone; include customization, freight, spare parts, after-sales support and downtime risk. Keep written records of inquiries, confirmations, FAT, acceptance and warranty commitments.
