*Bilateral, symmetric light distribution on two hemispheres
**One-sided, single hemisphere light distribution

*** Retrofit Kits and Replacement Lamps must be tested inside fixtures, per the policies for those products. See Outdoor 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 THD of ≤20%. This applies to every category listed in Table 1.6.

 

Lumen Maintenance: Explanation of LM-80 thresholds is below. The DLC uses a pass/fail threshold for lumen maintenance compliance, as established in the Energy Star Manufacturer’s Guide v2, pg. 7 (http://www.energystar.gov/ia/partners/manuf_res/downloads/ENERGYSTAR_Manufacturers_Guide_v2.pdf). The requirements differ for applications requiring 35,000 hours of useful life and those requiring 50,000 hours, as follows:

Table 2: Lumen Maintenance Requirements

Application required minimum useful life (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:
