Updating Dimming Information

As of July 2014, the DLC collects and reports the following information for all new products listed on the QPL:

  • Is the product capable of dimming?
    This will be indicated as “Yes,” or “No.” Previously-qualified products will indicate “Not Yet Verified” until a Dimming Update Application is submitted.
  • If the product is capable of dimming, how does the product dim?
    This will be referred to as the Dimming Type, and indicated as “continuous” dimming or “stepped” dimming.
  • If the product is capable of continuous dimming, is the product capable of dimming to 10% or below its full input power when installed in an appropriate system?
    This will be indicated as “Yes” or “No.”

You may update the listings of your previously-qualified products with dimming information by submitting a Dimming Update Application, which can be downloaded at the bottom of this page. Please note that you must identify the unique model number(s) for each product variation submitted in an application with different combinations of reported dimming information. Products with different performance with respect to these three dimming characteristics will not be permitted to be represented by the same model number listing on the QPL.

Due to the lack of an industry standard testing methodology to verify dimming capability and performance under dimmed conditions, DLC will not require testing be submitted to verify dimming performance at this time. The DLC will evaluate a manufacturer’s claims of dimming capability by ensuring that the dimming claims are clearly published in the product specification sheet and correspond with the unique model numbers submitted. DLC reviewers may check web listings and other marketing materials, and reserve the right to request additional information to demonstrate dimming capability if product specification sheets are not sufficient.

Dimming Update Instructions

 



Updating Nomenclature


Updating Nomenclature for Single and Family Grouping Products

To update product nomenclature for products qualified via the Single Product or Family Grouping application process, manufacturers must provide the following:

  • A signed statement on company letterhead that certifies no changes were made to the product (only to nomenclature), and briefly describes the reason for the nomenclature change. The statement must include the list of old and new model numbers. 
  • Completed Nomenclature Update Form (download at bottom of webpage)
  • Updated spec sheet(s) that reflects the nomenclature change



Updating Nomenclature for Private Label Products

To update product nomenclature for products qualified via the Private Label application process, manufacturers must provide the following:

  • A signed statement on company letterhead that certifies no changes were made to the product (only to nomenclature), and briefly describes the reason for the nomenclature change. The statement must include the list of old and new model numbers. 
  • Completed Nomenclature Update Form (download at bottom of webpage)
  • Updated spec sheet(s) that reflects the nomenclature change
  • Updated Private Label Agreement form that reflects the nomenclature change (download at bottom of webpage)

At this time, there are no fees associated with nomenclature update applications. To request a nomenclature change, manufacturers must submit the required documentation through their Manufacturer Portal, and select “Update” as the Application Type. 
 

 


 

Updating Performance

If a manufacturer wishes to update the listed performance of a qualified product, the manufacturer must provide new test data for the updated product and pay the associated application fee. This will require DLC review. If the manufacturer wishes to have the originally-qualified and updated products both listed on the DLC QPL, a new part number for the updated product must be provided to avoid duplicate model numbers on the QPL. If model numbers are not changed, the listing will be for the upgraded product only. Multiple products with identical model numbers may not be listed under the same product category on the QPL.

 



Updating to Premium

In order to update products on the QPL to the DLC Premium classification, manufacturers must submit the additional required information on driver ISTMT, safety certification, controls information, and L90 evaluation, along with a new application form and any other additional information not provided with the original application.
