In an integrated LED lamp, the driver is the product. Two lamps that look identical will age differently depending on what is inside.
ComplianceA Certification Is Not a One-Time Purchase
Listings are maintained through factory follow-up inspections. Buyers who never ask about that arrangement are buying a piece of paper.
ComplianceWhat Online Marketplaces Ask For When You Sell Lighting
Marketplaces enforce compliance with documents rather than with inspections. The document set is predictable, and it is worth having ready before the listing goes live.
