That is, products in this category operate utilizing an existing fluorescent ballast, and do not require mechanical or electrical changes to the fixture. Note that due to testing considerations, at this time only products that operate utilizing specific ballast types are eligible. Replacement lamps designed to operate utilizing magnetic ballasts or other types of electronic ballasts not specified are not eligible at this time. Also note that products claiming to replace T12 lamps are not eligible under Type-A primary use designations.

The lamp holders are then wired to receive only the low-voltage electricity that is supplied by that external driver. (See Testing and Reporting Requirements for Linear Replacement Lamps for more detail on testing requirements.) Please note reference to UL type is derived from UL 1993, 4th edition, 2012-12-04 Section SA6.13.1.

Eligible Color-Tunable Products

Two types of products are eligible for listing as Color-Tunable; White Tunable products and Warm-Dimming Products.

• If a product has any functionality that enables it to actively change the color (i.e. CCT) of the emitted light, it must be submitted under the requirements for color-tunable products. This includes products with a small set of color temperature settings controlled through mechanisms such as dipswitches set at the distributor or by the installer. In general such products will be deemed color-tunable and applications must be submitted according to the color-tunable requirements. Such products can be submitted as non-color-tunable if the products are not marketed as color-tunable and the mechanism to adjust color temperature is physically locked in place through a cover or other mechanical restriction.

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.
• 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.
• 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.
• 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.
• White-Tunable products CAN 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 CAN 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 must meet all DLC Technical Requirements at the maximum light output setting.
• Dimmable products CAN be classified as DLC Premium if they meet all DLC Premium classification requirements at the maximum light output settings.
• Dimmable products may also be capable of color-tuning, and thus are subject to both the Dimmable Products Testing and Reporting Requirements and the Color-Tunable Products Testing and Reporting Requirements.

Products with Field-Adjustable Light Output:

• Field-Adjustable Light Output is defined as a dimming type where products are capable of being adjusted to decrease or increase lumen output and wattage from the default setting. The default setting is defined as the setting at which the product emerges from production and is shipped with no adjustments to lumen output. The field-adjustable set point is fixed by the manufacturer, distributor, installer, or commissioning agent before or during installation or commissioning, via a control that is made discrete to that purpose via a proprietary process or separate control (i.e. not part of a regular occupant- or sensor-facing control system). Typically, the field-adjustable light output settings are not intended to be occupant interfacing.
