*     Bilateral, symmetric light distribution on two hemispheres

**    One-sided, single hemisphere light distribution

***   Bilateral for surface-mounted units, single hemisphere for corner-mounted units

****  Retrofit Kits and Replacement Lamps must be tested inside fixtures, per the policies for those products. See Retrofit Kit Policy and Four-Foot Linear Replacement Lamp Policy for details.

 

Power Factor and Total Harmonic Distortion: In addition to the specific requirements above, all DLC-qualified luminaires must have a power factor of ≥0.9, and a current THD of ≤20%. This applies to every category listed in Table 2.0. Qualified products must meet the requirements in their worst case loading conditions.

 

Tolerances: Below are tolerances that are applicable to all categories listed above in Table v2.0. These tolerances are referenced in the ENERGY STAR Manufacturer’s Guide. For zonal lumen tolerances specific to each category, please refer to Table 5.

Lumen Maintenance: DLC has two options for demonstrating lumen maintenance compliance. Option 1 is using component-level performance through the TM-21 protocols, which leverage the LM-80 performance and In-Situ Temperature of the LED device. More information is available in the Application Instructions. For products where the required lifetime is longer than the projection method allows, the necessary lumen maintenance minimums at the end of the allowable projection period are as follows. These percentages result from solving an exponential decay function for 35,000 and 50,000 hours. Please note that content and applicability of LM-80 reports will follow the guidance issued by ENERGY STAR.

Option 2 is to conduct 6000-hours of luminaire-level testing. For Option 2, DLC uses a pass/fail threshold for lumen maintenance compliance as established in the ENERGY STAR Manufacturer’s Guide v2, pg. 7. The requirements differ for applications requiring 35,000 hours of useful life and those requiring 50,000 hours, as follows:

Lumen Maintenance to L70

Required Lumen Maintenance at 6,000 Hours

35,000 hours

94.1%

50,000 hours

95.8%

These percentages result from solving an exponential decay function for 35,000 and 50,000 hours, respectively, to determine the minimum lumen maintenance necessary to achieve those thresholds. Products can demonstrate compliance with testing longer than 6,000 hours, according to the table below:

When applying the lumen maintenance in accordance with these protocols, DLC applies a tolerance of 5% to drive currents tested under LM-80.

Flood and Spot Lighting Categories:

For both architectural and landscape/accent flood and spot lighting categories, manufacturers must declare the NEMA Beam Classification (see chart below) of their luminaire in the 0-180 degree and 90-270 degree planes. DLC will verify these claims against the IES files provided.

Table 6: NEMA Beam Classification

Wall-wash Luminaires:

For clarity, the zonal lumen criteria for this category is that ≥60% of the lumens must be produced in the “forward” hemisphere, towards the wall.

 

Stairwell and Passageway Lighting:

DLC requires that products in the Stairwell and Passageway Lighting category to include integral controls for occupancy sensing and bi-level dimming. Documentation must be provided to demonstrate bi-level dimming capabilities, and occupancy sensing options must be designated clearly in the model number. Manufacturers must also declare whether the unit is intended to be surface-mounted or corner-mounted. All performance requirements in Technical Requirements Table v2.0 refer to the full power operating mode.

 

DLC Retrofit Kit Policy

DLC will accept QPL applications for SSL Retrofit Kits for certain available categories. The testing and reporting requirements described in the link below are intended to subject the retrofit kits to real-world thermal conditions in order to assure confidence in lumen maintenance. For more information, please refer to http://www.designlights.org/solidstate.manufacturer.instructions.outdoorretrofit.php.

 

DLC Four-foot Linear Replacement Lamp Policy

DLC will accept QPL applications for 4’ linear tube-style products intended to replace fluorescent lamps in this category. The testing and reporting requirements described in the link below are intended to evaluate the performance both of the lamp itself, and its performance in reference 2x4 troffers, their most common application. For more information, please refer to http://www.designlights.org/solidstate.manufacturer.instructions.linearreplacementlamps.php. Note that this category covers all four-foot LED tubes, including those that are direct, simple replacements for fluorescent tubes and those that require modifications to the existing fixture (such as bypassing the
existing ballast).
