- Outdoor Wall Lights
- Garage Lights
- Industrial Lighting
- Outdoor LED Fixtures
- LED Tubes
The V4.0 requirements include key performance metrics such as:
- Total Luminous Flux
- Beam Luminous Flux
- Luminous Efficacy
- Color Temperature
- Color Rendering Index (CRI)
- Luminous Maintenance
- Power Factor
- Harmonic Distortion
To achieve DLC certification, products must be tested by a third-party laboratory accredited by NVLAP (National Voluntary Laboratory Accreditation Program) and must provide a test report.
Products Applicable for DLC Certification Include:
- Outdoor Post-Top/Arm-Mounted Area and Roadway Luminaires
- Outdoor Post-Top/Arm-Mounted Decorative Luminaires
- Outdoor Wall-Mounted Area Luminaires
- Wall Wash Fixtures
- Landscape/Emergency Floodlights and Spotlights
