What the DLC Certification covers, who needs it, and how SZC-LAB tests and certifies your product for United States.
DesignLights Consortium listing for commercial LED lighting, widely required for US utility rebate programmes.
Market context: Federal radio and energy rules plus state-level and retailer requirements - several US "certifications" are voluntary programmes rather than legal obligations.
No - the DLC Certification is not a legal requirement for United States. It is applied for voluntarily, but in practice buyers, retailers and tender documents frequently request it, so most exporters treat it as commercially mandatory.
The DLC Certification is only as strong as the test report behind it. We run the underlying work - Energy Efficiency Testing and the related programme for your product - in our own CNAS & ILAC accredited laboratory in Shenzhen, then prepare the documentation the DLC Certification application is built on.

It depends on the scheme - some marks are valid continuously with periodic surveillance, others need renewal or an annual factory inspection. We track the applicable maintenance cycle for you as part of the project.
