As we know that, ETL, CSA or UL certificate is not mandatory in North America, many customers, especially lighting retailers or contractors, would request it before purchase or installation, because this certificate means the product, the materials and components used in the product, is safe.
But before purchasing a safety certified lighting product, make sure check these 3 points:
1) Make sure the certificate is issued by UL, CSA, or Intertek.All three certificates are widely accepted in US and Canada. UL owns the UL standards for US and also certifies product, the mark is UL for US and cUL for Canada, CSA owns the CSA standards for Canada and also certifies product, the mark is CSA for US and cCSA for Canada. Intertek does not own the standards, only certifies product by conforming with UL standards in US and CSA standards for Canada, the mark is ETL for US, and cETL for Canada.
2) Make sure the control number on the certificate is for the supplier.
3) Make sure the product is among the certified models.
