Family Grouping Applications
To submit a Family Grouping Application, your family group should meet the following definition:
- A family must contain a single LED package/module/array, or standardized set of LED packages/modules/arrays (see requirements for multiple LEDs).
- The fixture must demonstrate scalability or modular use of the identical LED packages/modules/arrays electronics, optics, heat sinking, and any other applicable features.
- Other design parameters and components, such as electronics, optics, heat sinking, and other performance-affecting and non-performance affecting features are typically allowed to vary, consistent with this policy and provided that impact on performance is well understood and explained by the applicant. The DLC reserves the right to request additional information confirming that these features do not affect performance.
- A family may contain multiple driver variations as well as different LED drive currents achieved by an adjustable driver.
- The overall physical fixture housing and assembly of the products in the family group is of identical material, construction, and shape, and differs primarily in overall physical dimensions for different models within the product grouping. If the family group differs in overall dimension for different models within the group, each dimensional change will be grouped in a sub-group.
- Decisions on whether a given group of products are eligible to be submitted in the same family grouping application is at the sole discretion of the DLC. Variation in materials, designs that change the position of key components relative to one another, and other variations that, in the judgement of the DLC, have potential to cause differences in optical, electrical, or thermal performance, will generally not be allowed within the same family group.
- A family may contain variations in fixture mounting systems if mounting systems do not change thermal management characteristics.
- If multiple driver variations are included within the family group, please refer to the Testing Requirements for specific instructions.
- Manufacturers must list full and complete model numbers that clearly demonstrate all product options offered in the family grouping in all application submissions.
- “Full and complete model numbers" means model numbers that include all performance-affecting and non-performance affecting variations offered, and which do not omit any option that is available to customers in the market. In general, options that do not affect the performance of the product can be submitted as a single model number with multiple options bracketed in the model number. For example, a product that has multiple exterior paint color, mounting, plug, or other options, that do not affect performance, may include all options in brackets (e.g. "[WH, BLK, SLV, GRY]" or “[All Options]”) within a single model number. Any options that are not present on the submitted specification sheet or supplemental documentation will not be considered qualified and a new specification sheet, supplemental documentation, and/or test reports may be required for options added to the luminaire after qualification. Low and high voltage options can be submitted as a single model number (e.g. "ABC 10LM [120V-277V, 347V-480V] WH") with the worst case performance reported. Multiple or alternate drivers can also be listed in a single model number as long as the drivers perform nominally the same. If the alternate drivers perform nominally differently – that is, they are not presented to customers as having the same performance other than voltage input, and result in different ordering codes – then the unique drivers will need to be listed in separate model numbers. Options that affect the lumen output, presence or lack of dimming capabilities, FALO, FALD, color tunable, or DC/POE cannot be bracketed and submitted as a single model number.
- DLC reviewers may check web listings and other marketing materials and reserve the right to request additional information to demonstrate the full and complete model number. A lack of clarity in model numbers will result in delayed application processing; misrepresentation of model numbers in the application process discovered outside the application process will generally be considered a violation of the DLC program and trademark rules.
- Each model number can only represent the fixture under a single brand. If the fixture can be sold under multiple brands, model numbers will need to be listed separately for each brand.
Testing Family Grouping Products
The Family Grouping testing policy is designed to reduce testing burden as well as reduce the total application fees required by manufacturers to list groups of products that comply with the Family Grouping definition, relative to testing and listing all products individually. By identifying the worst case models within a family group, limited testing can be provided if the worst case models demonstrate compliance with the Technical Requirements.

Family Grouping Application Instructions
- Determine if your product is eligible to be qualified by the DLC and meets the Technical Requirements.
- Please see Product Eligibility to determine if the DLC accepts applications for your product type.
- See the Technical Requirements to determine whether your product meets DLC minimum performance requirements.
- Review Testing Lab Requirements and category-specific Testing and Reporting Requirements to ensure your product has been properly tested. to ensure your product has been properly tested.
- Create a Manufacturer Account.
If you have not done so already, create a manufacturer log-in. The DLC recommends that the application be completed by a person with technical knowledge of lighting products and testing, such as a product engineer. Experience has shown that applications submitted by non-technical staff may lack important details which can delay overall processing.
- Complete the Product Application Form.
Download the Product Application Form (.xlsx) at the bottom of this page. See the Product Application Form Instructions download for specific information about completing the application form.
- Start a new application in your Manufacturer Account.
Once logged in, click the Applications tab on your Dashboard. Click the green Create Application button. This will lead you to the Create New Application window. Enter the required Application Details and Application Contact information. Be sure to select the SSL Family Grouping application type. After creating the application, you will be redirected to the Application Home.
- Upload ALL required application materials. Learn more about application supporting documentation here.
To upload supporting documentation, click the Documents section in the left-hand navigation menu of Application Home. Within the Documents section, each question requires a specific document to be uploaded. Questions are determined by the selected application type. Files must be individually uploaded in order to save your progress. All "Required Documentation" must be uploaded before you can submit the application. "Optional Documents" are necessary for evaluating products against the Premium classification requirements and certain Primary Use designations. The system will allow you to replace and delete files as necessary before submitting your application.
- Completed Product Application Form (.xlsx)
- Manufacturer product specification sheet You must submit the specification sheet being used in the marketplace. Specification sheets created for DLC submission only are not acceptable. Product specification sheet must clearly detail dimming capabilities if products are capable of dimming.
- LED package/module/array specification sheet (i.e. the specification sheet for the element that was tested for LM-80)
- IES LM-79-08 report(s) containing sections 9, 10, and 12
- Supplemental power quality test report or LM-79 with worst case power factor and total harmonic distortion (THD) measurements (If not included in primary LM-79)
- IES photometric file (.ies) Note that IES files are evaluated for zonal lumen density and/or spacing criteria compliance using Photometric Toolbox – Professional Edition from Lighting Analysts, Inc. IES files must be show the product oriented as it would be mounted in the field, with the exception of products in the Landscape Flood and Spot Luminaires and Architectural Flood and Spot Luminaires primary use designations (PUDs). For products seeking qualification in these PUDs, IES files must be oriented with the center of the beam at 0,0 angle.
- Legal warranty document explaining warranty terms and conditions
- Proof of safety certification from an appropriate safety certification body relevant in the US or Canada All products are required to submit a compliance certificate from an approved safety certification organization relevant in the United States or Canada.This compliance document shall bear the manufacturers name and will be proof that the products listed have been investigated by the safety organization and found to be in compliance with the standards listed on the certificate. The name of this document varies by safety organization, however, is commonly referred to as a Certificate of Compliance or Authorization to Mark. More information.
- Product installation instructions (only required for retrofit kits and linear replacement lamps)
- Lumen maintenance information
- Test Report Authorization form (only required if the submitting organization's name is not represented within your test reports)
Important: all supporting documentation must include the specific, relevant model or part number. Documents and files related to the luminaire, (e.g., LM-79, ISTMT) must include the unique model number of the luminaire that is included on the application. Documentation related to the LED package/model/array (e.g., the LM-80 report) must include the part number of the specific LED package/module/array that is named in the application. Please communicate with any independent laboratory the exact luminaire model number that it should include in its test reports. Visit our FAQs page for further clarification regarding test reports.
