Application Instructions for Product Families

We define luminaire families as luminaires that may use a different housing color or different CCT, but can still be validated to meet DesignLights specifications without requiring individual review of testing reports. Please use the ENERGY STAR Manufacturer’s Guide for SSL Luminaires as a reference for family submittals, and read below for further clarifications.

If you plan to submit a luminaire family, you will need to describe what other options or accessories are included in the family, and make sure all test reports are based on the product variation of that family. Furthermore, pick your 'worst case', one that produces the least light output with the greatest input power. As a guide to estimate relative light output, typically a certain luminaire using a specular reflector produces more light output than the same luminaire using a diffuse reflector, and a luminaire with a white trim produces more light output than that with a black trim.

please refer back to the SUMMARY OF TECHNICAL REQUIREMENTS TABLE for requirements.

For each application, the applicant may submit only one product model number for evaluation. This submitted model number has to be a detailed model number such as “ROADWAY-TYPE2-XYZ-700MA-5000K-BLK”, and it can not represent a whole family of different models such as “ROADWAY-TYPE2-xxx-xxxMA-xxxK-xxx” with undefined accessory options.

If the applicant wants to include any other model (call it “family model”) in the same product family as the submitted model, this “family model” must be identical to the submitted model except for the following three scenarios:

The “family model” exterior housing has a different color
The “family model” uses the same LED chip model as the submitted model but the LED chip has a different phosphor that produces a higher CCT value than the submitted model
The "family model" is a refrigerated case end mounted fixture that is symmetric with the opposite end mounted fixture. (e.g.If the application is for the right end fixture, the left end fixture is a family member.)

The applicant has to provide proof that the difference between the “family model” and the submitted model is limited to the above two scenarios. Any other difference from the submitted model constitutes a different product family.

Please list all detailed “family model” numbers separately in the submission form. When the “family model” is listed in the Qualified Product List, it will carry the same data values as the submitted model, which is intended to be the lowest performance of the product family.

EXAMPLES

Applicant A1 submitted data for a fixture model “ROADWAY-TYPE2- XYZ-700MA-5000K-BLK” to DLC website for evaluation, and the product literature shows it uses LED chip Manufacturer M1’s “XYZ-5000K” LED chip with a drive current of 700mA.

Below are a few examples of fixture models that can be included as “family model” for the submitted model:

ROADWAY-TYPE2- XYZ-700MA-5000K-WHT (only differ in exterior color)
ROADWAY-TYPE2- XYZ-700MA-6000K-BLK (only higher CCT)

Below are a few examples of fixture models that can not be included as “family model” for the submitted model:

ROADWAY-TYPE3- XYZ-700MA-5000K-BLK (different light distribution)
ROADWAY-TYPE2- ABC-700MA-5000K-BLK (different LED chip model, leading to different optical and electrical performance that may be worse than the submitted model)
ROADWAY-TYPE2- XYZ-350MA-5000K-BLK (different drive current)
ROADWAY-TYPE2- XYZ-700MA-4000K-BLK (CCT lower than submitted model)
ROADWAY-TYPE2- XYZ-700MA-5000K-BLK-DoubleLEDs (a different number of LED chips)
