Product Eligibility

Product Eligibility

The DLC qualifies commercial LED luminaires, retrofit kits, linear replacement lamps, mogul (E39) screw-base replacement lamps, and four pin-base replacement lamps for CFLs for inclusion in DLC Members' energy efficiency rebate and incentive programs. Available Primary Use Designations are prioritized and developed by DLC energy efficiency program Members. Any rebates or incentives are provided at the discretion of each individual energy efficiency program.

Products submitted for qualification must be marketed as and intended for one of the available Primary Use Designations below to be eligible. 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 in reference to the Primary Use Designation or application under which a product was qualified. Please note: the DLC is in the process of developing a specification for horticultural lighting products. Until this specification is finalized, any product marketed for horticultural applications is explicitly ineligible for listing on the QPL.

Eligible "Specialty" Primary Use Designations
 

The "Specialty" designation has been developed as an additional tool for DLC and its Member programs to employ in seeking to identify high-quality, energy-saving LED fixtures in commercial and industrial applications for certain niche applications for which DLC has not yet developed a specific Primary Use designation.

Seeking qualification of a product using this Primary Use designation is an acknowledgement of the rules of the program and a confirmation that an applicant agrees to abide by the decisions of the program. Products with a Specialty designation are not eligible for DLC Premium classification.

Eligible Color-Tunable Products

 

White-Tunable Products:


White-Tunable products have a control signal specifically for adjusting CCT while maintaining nominally constant lumen output. These products may include a second, independent dimming control. White-Tunable products include both “white-white” products that combine the output of 2 LED primaries, and products with 3 or more white and/or RGB LED primaries, so long as they only produce white light as characterized above in response to their control signal.

  • White-Tunable products are not eligible to be submitted as Single Product Applications. Both single products and product families must submit a Family Grouping Application and meet all the Family Grouping eligibility requirements. For the purposes of color tuning eligibility, the DLC’s existing requirements that a family must contain a “standardized set of LED packages/modules/arrays” and must demonstrate scalability or modularity using “any other applicable features” apply also to White-Tunable families, in that they must have identical chipsets and modular groupings of chipsets, resulting in an identical technological approach to color output.
  • White-Tunable products must meet the DLC Technical Requirements at all values of the color control signal for the General Application(s) and Primary Use(s) for which they are submitted, except for CCT. This includes minimum light output, efficacy, CRI, lumen maintenance, THD, Power Factor, and zonal distribution/spacing criteria requirements.
  • White-Tunable products must be capable of producing light at CCTs in alignment with existing maximum CCT limits for DLC qualified products. However, no maximum or minimum CCT range is required for color tuning eligibility in general.
  • White-Tunable products will only be classified as DLC Premium if they meet all DLC Premium classification requirements (except CCT) at all values of the color control settings. Additional documentation may be required.
  • White-Tunable products may also have field-adjustable lumen output characteristics, in which case they are also subject to the Field-Adjustable Product Testing and Reporting Requirements. If products exhibit both performance features, they must comply with both White-Tunable and Field-Adjustable Product Testing and Reporting Requirements.


Warm-Dimming Products:


Warm-Dimming products have a single input which controls both color temperature and lumen output, lowering the values of both concurrently, most typically to mimic the color temperature shift of incandescent dimming. Products that require an external control system to coordinate dimming and warming color temperature are not eligible.

  • Warm-Dimming products must meet all DLC Technical Requirements, including CCT, for the General Application(s) and Primary Use(s) for which they are submitted, as measured at the maximum output for the product. The requirements include minimum lumen output, efficacy, CRI, CCT, lumen maintenance, THD, Power Factor, and zonal distribution/spacing criteria requirements.
  • Warm-Dimming products do not need to meet DLC Technical Requirements at other input control settings, i.e. when they are dimmed below full output.
  • Warm-Dimming products will only be classified as DLC Premium if they meet all DLC Premium classification requirements at the maximum input control setting.
  • Warm-Dimming products may also have field-adjustable lumen output under the Field-Adjustable Product Testing and Reporting Requirements, and thus be listed under both. If products exhibit both performance features, they must comply with both sets of requirements.
   


Eligible Dimmable and Field-Adjustable Products


Dimmable Products:


Dimmable products are capable only of being adjusted to decrease lumen output and wattage from the default setting.Dimmable products must have a lumen output control that can be adjusted post-installation, dynamically, or on a scheduled basis, via a control system signal, or an occupant interface such as a switch or app.


Products with Field-Adjustable Light Output:


Field-Adjustable light output products are capable of being adjusted to decrease or increase lumen output and wattage from the default setting.
