V5.0 Focus Areas

The DLC will address three main focus areas with V5.0 to achieve the goals of the V5 program.

• 

  Efficacy Increase

  Version 5.0 of the Technical Requirements is designed to balance the trade-offs between efficacy, quality of light related to performance and wellbeing, and cost considerations of lighting products on the QPL. Quality of light must go hand-in-hand with energy efficiency if long-term energy savings are to be realized.

  Objective: Increase the minimum efficacy requirements for listing on the QPL without sacrificing quality of light of listed products.

• 

  Controllability of Light

  Controllability refers to the capability to control a light source by dimming it; turning it off or on in response to a sensor or signal; or changing the color (or spectrum) of light over time to mimic sunlight, among others. Increased controllability of lighting can save more energy and provide higher quality of light by enabling the ability to tune lighting to just what is needed or preferred for a person, task, or application.

  Objective: Increase lighting controls adoption to better realize energy savings and improved quality of light.

• 

  Quality of Light

  Quality of light describes the aspects of light that impact productivity, performance, comfort, aesthetics, mood, safety, health, and wellbeing. Lighting that provides comfortable, safe environments for people is critical, leading to wider adoption and persistent energy savings.

  The DLC is providing information about the quality of light properties of listed products in its proposed Technical Requirements V5.0 for the following topics. Click the green info buttons to learn more.

  • Color Quality
  • Flicker
  • Glare
  • Optical Distribution

  Objective: Improve the quality of light in the built environment, helping to ensure safe, comfortable, and productive settings for people, mitigating negative impacts of electrical light, and realizing lasting energy savings.
