– I submitted a test report that meets the Technical Requirements, but noticed that there is incorrect information reported. Will the DLC accept a revised test report?
If there is incorrect information found in the LM-79 or ISTMT, the DLC will accept a revised test report. All test report revisions must follow the rules set forth by the accreditation body. In the event the applicant chooses to retest the product instead of provide a revised test report, the DLC will only reevaluate the new, retested data. Data issues encountered in LM-80 reports will be handled on a case-by-case basis. The DLC urges applicants to thoroughly review all application documentation prior to submittal to ensure all information is accurate.
Please note that this FAQ applies only to situations where incorrect information does not suggest that the product fails to meet the Technical Requirements. In the event that a test report shows a performance value that fails Technical Requirements, please see the FAQ: “I submitted a test report that contains failing data, but believe this data does not represent my product’s performance. Will the DLC accept a new report with different performance on the same product design?”
-Why am I required to submit an explanation of the ordering code/model number breakdown in the Application Form?
Understanding the available options for a product is necessary to ensure worst case performance has been identified and tested. As such, an explanation of the ordering code/model number breakdown must be included in the relevant section of the Application Form and must match the spec sheets and other marketing materials submitted with the application. DLC reviewers reserve the right to request additional information or clarification of ordering codes or model number breakdowns. Please note that omitting or submitting an insufficient ordering code/model number breakdown explanation is one of the most common reasons application reviews are delayed.
-I believe that the drive current information presented in my Application Form does not correctly represent my product’s performance. Will the DLC accept revised drive current information on the same product design?
In situations where the originally-provided drive current information impacts whether or not the product will meet the lumen maintenance requirements, revised drive current information will typically not be accepted, unless the product is redesigned, retested, and resubmitted. The DLC reserves the right to review changes to drive current that impact eligibility on a case-by-case basis to determine whether revisions without a redesign are acceptable. This supports efforts to maintain the integrity of the product data listed on the QPL.
Please note that in all situations, it is expected that the drive current information within the Application Form accurately represents that product’s performance. The Self Certification Statement provided with each application includes language that the applicant certifies all model numbers submitted meet minimum requirements and that the information provided in the application is accurate.
In the event where a manufacturer chooses to make a design change to the product and resubmit test data that represents that design change, the DLC will need detailed explanations of the changes made as well as assurance that the changes will be reflected in all products sold.
-What types of signatures does the DLC allow?
Acceptable forms of signatures include either a wet signature or verified digital signature. The signature must be affixed to the document, unable to be moved. Wet signatures must be written on a print-out of the document with a pen, then scanned and submitted. Verified digital signatures must authenticate the electronic user and capture the user’s intent to sign the document. Software may not auto-sign on a signee’s behalf.
-Is proof of safety certification required for Update Applications?
Yes. As of Technical Requirements V4.3, implemented on March 26, 2018, providing safety certification documentation is required for all types of Update Applications. Please refer to the Safety Certification page for more information on what safety certification documentation is required.
-Can I test a prototype for my DLC submission?
No. The DLC is interested in the performance of the production-ready product seeking qualification. As such, test data on prototypes will not be accepted for DLC submissions. Testing must be on production-ready models that are identical in design and construction to those that are being or will be sold.
-What are the color temperature requirements for a white-tunable product to be listed on the QPL?
There are no color temperature limitations regarding the color-tunable feature for standard product listing on the QPL. However, the existing Technical Requirements specific to the product type must be met. For instance, outdoor products are not limited to a color temperature range but must be capable of light output at ≤ 5700K (per the nominal ANSI binning descriptions). Please consult the Technical Requirements for color temperature specific to the General Application and Primary Use Designation under which the product will apply
-Can products within a white-tunable family grouping application have different tunable ranges?
No. The DLC requirements state that products within a family group of white-tunable products must have the same types of LEDs, and an identical technological approach to color output. This is intended to include a restriction that all products within a family group have the same tunable range. Therefore, as an example, if one version of a product can tune from 2700-5000K, while another version can tune from 2200-6500K, they must be submitted under separate applications, with independent testing.
– I’m submitting a Single/Family application, but my safety certification documentation includes a multiple listing document. What documentation and information should I submit with my DLC Single/Family application?
If submitting a Single/Family application where the safety documentation involves a multiple listing document, please submit the private labeler compliance certificate and populate the Application Form with the safety organization and private labeler safety file number. If the safety organization has not provided a private labeler compliance certificate, one will need to be obtained from the safety organization in order to proceed with the Single/Family application process.
-I am submitting an application containing White-Tunable products. What performance data should I enter into the Scaled Performance Table?
When submitting an application containing White-Tunable products, the Scaled Performance Table must be populated with the performance data representative of the least efficacious setting of each product seeking qualification. For more information regarding White-Tunable applications, please refer to Testing and Reporting Requirements for Color-Tunable Products
-I have a product that can be ordered with multiple luminaires mounted on a singular mounting structure. Can I qualify the options for each ordering configuration within one model number on the QPL?
Yes, under specific circumstances. Configurations of multiple luminaires mounted on a singular mounting structure can be listed in one line item on the QPL, provided that each mounting configuration includes only identical luminaires, and the configuration of luminaires is identifiable in the ordering code nomenclature. This provision is only applicable for products within the Outdoor Pole/Arm-Mounted Area and Roadway Luminaires, Outdoor Pole/Arm-Mounted Decorative Luminaires, Landscape/Accent Flood and Spot Luminaires, and Architectural Flood/Spot Luminaires Primary Use Designations.
Additionally, products that wish to utilize this listing approach must be submitted via a Family Grouping application. An example of a product design that would be eligible for bracketing includes a pole-mounted area luminaire that can be ordered in configurations of 1, 2, 3, or 4 luminaires mounted to a singular pole. In this example, the 1, 2, 3, and 4 luminaire configurations can be bracketed within a singular model number. The form of the model number should be submitted as:
- ABC-123-[1, (2, 3, 4 see notes)]
The “Notes” field on the QPL will then state:
- “Available in configurations with multiple identical heads where model number indicates 1=1 fixture, 2 = 2 fixtures, 3 = 3 fixtures, 4 = 4 fixtures”, etc… – as needed based on specific number of configurations offered using identical fixtures
