Understanding the QPL

 

DLC publishes manufacturer and model identifying information, as well as verified worst case tested performance or reported performance information for each product.

These fields include:
  • Manufacturer
  • Brand
  • Model Number
  • Qualification Date
  • Listing Status (Listed or Delisted)
  • Technical Requirement Version
  • General Application type
  • Primary Use type
  • DLC Classification Type (Standard or Premium)
  • Electrical System Type (AC/DC)
  • Luminaire Efficacy
    • Luminaire efficacy should be reported as the total luminous flux from the fixture divided by the total input power. Luminous flux is based on the photopic luminous efficiency function (V lambda), not scotopic or mesopic efficiency.
  • Light Output (lumens)
  • Power Factor and Total Harmonic Distortion (THD)
  • Correlated Color Temperature (CCT)
  • Color Rendering Index (CRI)
  • Wattage
  • Light Distributions (i.e., zonal lumen density, NEMA classification, and/or spacing criteria)
  • Input Voltage Range -Parent only
  • Dimming Information (reported)
  • Control Info (reported)
  • Parent or child designation
    • Parent products display tested and reported data and are displayed on a green tile
    • Child products display reported data, are listed under each associated parent product, and are displayed on a gold tile 
  • Private label versions of products display exactly the same performance information as their OEM versions.
 
No two model numbers can be listed under the same product category on the QPL for one given manufacturer. If a manufacturer submits the same model number for multiple products, the DLC reviewer will insist the manufacturer make some distinction in the model numbers that represent the variations of the product. The utility and consumer must be able to identify the differences between products from the model number listed on the QPL.
