DLC Trademarks – Words and Logos Defined

The DesignLights Consortium (“DLC”) has three main registered logos (“DLC Logos”), which are:

DLC Logos

The DLC also has two main registered trademarks (“DLC Trademarks”):

  1. “DesignLights Consortium” and
  2. “DLC”

Collectively the DLC Logos and Trademarks (pictured above) are all either pending applications or registered trademarks in the U.S., Europe, Canada, China, and Mexico. As with any asset with appreciable value, all of the trademarks must be properly used and protected.

The DLC Logos and Trademarks are not only a valuable asset to the DLC, but are equally valuable to all DLC Members and product manufacturers who have products listed on the DLC Qualified Products List (“QPL”). In order to retain that value, all stakeholders must use the DLC Logos and Trademarks consistently and in compliance with these Guidelines in all communication and marketing materials. Ensuring that the DLC Logos and Trademarks are properly used protects every DLC stakeholder’s investment in the program—and consumer confidence in the DLC brand.

 

Authorized Use of the DLC Logos and Trademarks

As a general rule, third parties (i.e., anyone other than the DLC and those granted explicit permission by the DLC) are not allowed to use the DLC Logos and Trademarks without permission. The purpose of the DLC Logo and Trademark Use Guidelines is to provide clarification about how the DLC Logos and Trademarks should be used by its stakeholders. The DLC Logos and Trademarks must always be used pursuant to the specifications in these Guidelines to identify the DLC or participation in the DLC program. Any use that falls outside of these specifications is strictly prohibited.

Participants in the DLC program agree to the DLC Logo and Trademark Use Guidelines and all DLC rules and policies, which may be updated at any time. Participants must acknowledge that the DLC (through Efficiency Forward, Inc.) is the sole owner of the DLC Logos and Trademarks, and agree not to interfere with the DLC’s rights in them, and acknowledge that goodwill derived from their use accrues only to the DLC. The DLC will review stakeholder’s use of the DLC Logos and Trademarks on a number of materials, including specifications sheets, website, and other marketing materials. The DLC reserves the right to request modification for any non-compliant use as well as terminate participation in the DLC program for continuous violations of the Guidelines.

The DLC Logos and Trademarks and authorized participation are as follows:

 

I. The DLC Program Logo:

For use by:

DLC Members*
To indicate membership in the DLC Program on DLC Member webpages.
DLC Members are regional, state, utility, and energy efficiency programs who support the DLC Program though member agreements throughout the U.S. and Canada

Lighting Testing Laboratories
To indicate available product testing services necessary for manufacturers to submit an application to the DLC QPL. NOTE: Laboratories must meet the DLC accreditation requirements to display the logo. The DLC Logos and Trademarks may not be displayed in test reports or be used in a manner that implies the DLC endorsement of a laboratory or its services.

Manufacturers and Distributors
May not use the Program Logo without explicit permission by the DLC.

Other
Additional use of the DLC Program Logo will be assessed on a case-by-case basis. Please contact info@designlights.org

 
Guidelines for Use of the DLC Program Logo
  • The DLC Program Logo may not be altered, cut apart, separated, or otherwise distorted in perspective or appearance.
  • The preferred color for the DesignLights Consortium mark is black for the text and yellow for the graphic. Alternate versions – such as a reverse-color logo with white text and yellow graphic - are allowed. PLEASE refer to the style guide for information on the Standard and Alternative ways to use the DLC Program Logo.
  • The DLC Program Logo must be large enough so that the lettering inside the logo is clearly legible in all mediums.
  • The DLC Program Logo must be clear within “C” space of logo elements from all sides.
  • The DLC Program Logo size should never be under 1.72 inches wide and .45 inches high to maintain legibility.
     
Common Mistakes to Avoid
  • Do NOT reproduce the DLC Program Logo smaller than 1.72 inches (width) and .45 inches (height).
  • Do NOT use the DLC Program Logo to indicate a DLC product as DLC qualified (premium or otherwise) and vice versa. Each logo was created for a specific purpose and they should not be confused.
  • Do NOT copy the DLC Program Logo from the internet; please contact info@designlights.org for the official image files.

For further instructions on the use of the DLC Program Logo, please review the DLC Program Logo Style Guide.

 

II. The DLC QPL Product Logo

DLC QPL Product Logo

III. The DLC QPL Premium Logo

DLC QPL Premium Logo

The following guidelines apply to the use of both the DLC QPL Product Logo and the DLC QPL Premium Logo (“DLC QPL Logos”). Whereas the DLC QPL Product Logo may be used for both qualified luminaires and qualified networked lighting controls systems, the DLC QPL Premium Logo is not applicable to the controls systems.
 

For Use By:

Manufacturers and Distributors (including private labelers)
To indicate that certain products have been DLC qualified and are listed on the QPL.
NOTE: Use may be of the DLC QPL Product and Premium Logo (pictured above), or Approved Terminology, such as (1) “Product X is a DesignLights Consortium qualified product;” (2) “Product Y is listed on the DLC QPL;” or (3) underneath the product, indicate “DesignLights Consortium Qualified luminaire/system” or “a luminaire/system that is listed on the DesignLights Consortium Qualified Products List.”
 

Guidelines for Use of the DLC QPL Product and DLC QPL Premium Logos
  • The DLC QPL Logos may not be altered, cut, separated, or otherwise distorted in perspective or appearance.
  • The preferred color for the DLC QPL Logos is black and yellow. Similar to the DLC Program Logo, there are alternative formats available. Please refer to the style guide for information on the Standard and Alternative ways to use the DLC QPL Logos.
  • The DLC QPL Logos must be large enough so that the lettering inside the logo is clearly legible in all mediums.
  • The DLC QPL Logos must be clear within “C” space of logo elements from all sides.
  • The DLC QPL Logos should never be under .5 inches wide and .5 inches high to maintain legibility.
     
Use of the Logos on General Marketing Materials

General Marketing Materials are defined as Website Home Pages and General Information Pages such as About Us Pages, Covers of Brochures and Catalogs, Tradeshow Booth Displays - not in reference to specific products.

  • A pre-requisite for use of the DLC QPL Logos on general marketing materials is that the user in question must have products listed on the DLC QPL under the appropriate classification, or else the user must cease use of the DLC Product and Premium Logos immediately.
  • The DLC QPL Logos may be used on general marketing materials to indicate the user has products listed on the QPL without reference to the exact model numbers that appear on the QPL.
     
Use of the Logo on Product-Specific Marketing Materials
  • The DLC QPL Logos or Approved Terminology may only be used in association with specific products or control systems that have been verified to meet the technical requirements of the DesignLights Consortium and which appear on the DLC QPL.
    • The DLC Premium logo may only be used in association with products that have been verified to meet the technical requirements of the DLC Premium classification and which appear on the DLC QPL.
  • In order to use the DLC QPL Logos for Solid State Lighting products, the user must provide the exact model numbers or DLC Product Codes on the marketing material.
    • This information will allow the reader to locate the identified product on the most current version of the DesignLights Consortium Qualified Products List without further aid.
    • If not all products on the specific marketing materials are qualified, the user must indicate so in a clear manner so that the reader can easily determine which products are listed.
    • If a product was not qualified under all Primary Use Designations or applications that it is sold and marketed under, the user may only claim DLC qualification or use the DLC QPL Logos in reference to the Primary Use Designation or application under which a product was qualified.
  • In order to use the DLC QPL Logos for Networked Lighting Control systems, the user must provide the qualified system name on the marketing material as it is listed on the Networked Lighting Control QPL.
  • Products or control systems which have not yet been qualified should under no circumstances display the DLC QPL Logos.
    • For practical purposes, this means that users applying for qualification for their products should refrain from adding the DLC QPL Logos to specification sheets and other marketing materials until after the product has been qualified. Application submissions received with the DLC QPL Logos already on them will be held until that use is corrected.
  • Users who sell but do not manufacture products or systems listed on the DLC QPL (e.g. distributors) must include the name of the manufacturer and manufacturer’s model number(s) prominently and in proximity to DLC QPL Logos. Organizations who use their own name and model number in any form to market products must submit a private label application.
  • Manufacturers are responsible for ensuring that they, as well as any of their distributors and private labelers, use the correct model number on qualified products and that the DLC QPL Logos are being properly used on websites and specification sheets and materials.
    • Manufacturers must list their products on the DLC QPL under any and all brand names under which they are marketed and sold – even the ones that are private labeled.
    • To ease the process of re-listing qualified products under alternate brand names, please consult the Private Labeling/Multiple Listing Policy.
       
Common Mistakes to Avoid
  • Do NOT remove any of the wording, such as DLC, QPL, or LISTED from the DLC QPL Product Logo, and PREMIUM from the DLC QPL Premium Logo.
  • Do NOT reproduce the DLC QPL Logos smaller than .5 inches (width) and .5 inches (height).
  • Do NOT use the DLC QPL Logos to indicate membership in the DesignLights Consortium.
  • Do NOT use multiple model numbers for your qualified products; the model number that is on the DLC Qualified Products List MUST match the model number used by manufacturers and distributors on websites and specification sheets and materials.
  • Do NOT use the DLC logos or claim DLC qualification in association with product applications or Primary Use Designations under which the product model numbers were not qualified.
  • Do NOT use the DLC logos or claim DLC qualification in association with product applications or Primary Use Designations that do not exist.
  • Do NOT place the DLC QPL Logos directly on your product or product packaging, regardless of the status of qualification. The logos are intended for use on websites and marketing materials only.
  • Do NOT copy the DLC QPL Product Logo, or the DLC QPL Premium Logo from the internet; please contact info@designlights.org for the official image files.
    • NOTE: Specific model numbers should be included in all requests for DLC QPL Logos files.
  • Do NOT use the DLC QPL Logos on non-DLC qualified products.
    • This includes products that are marketed by the same manufacturer or under the same brand name and products that are currently under review with the DLC.
  • Do NOT use the DLC QPL Premium Logo for products that are NOT qualified as PREMIUM products.
    • This includes products that are qualified products on the QPL, but not qualified as PREMIUM products on the QPL.
  • Do NOT use any of the DLC QPL Logos in any other company name, product name, service name, domain name, or website title.
  • Do NOT place the DLC QPL Logos in e-mail signature blocks or business cards.
  • Do NOT use the DLC QPL Logos to imply a DLC endorsement of a company, product, or service.

Unauthorized/Improper Use:

Unauthorized and/or improper use of the DLC Logos and Trademarks, namely, not following these Guidelines, causes confusion among consumers, which compromises the DLC brand and its reputation.  It may also constitute trademark infringement, trademark dilution, false advertising, fraud and/or other violations of law. The DesignLights Consortium actively monitors the use of the DLC Logos and Trademarks, but also requests the assistance of its stakeholders to help police its brand. To report a trademark violation or to ask for a review of materials, please contact info@designlights.org.

Upon discovery of a DLC Logo or Trademark violation by a user, the DLC will take the necessary steps to have that violation corrected as quickly as possible in order to minimize the damage. The DLC expects that all stakeholders will endeavor to be compliant with these Guidelines and will make all changes requested by the DLC in order to achieve compliance.
 

Violations of Logo Guidelines

In case of DLC Logo and Trademark misuse, the DLC reserves the right to suspend the user’s program privileges for up to 18 months. This may include a suspension (de-listing) of all currently qualified products, as well as an inability to qualify additional products during the suspension. The DLC will notify the user of the violation and consequences.

In addition to suspension and/or de-listing of products, the DLC reserves the right to charge a fee to cover legal expenses of the DLC trademark compliance program. Such a fee may start at $250 per violation, depending on the severity of the infringement.
