Adaptive lighting means varying lighting levels as needed during peak and non-peak times to maintain safety and visibility while reducing energy consumption.

Cities participating in the Outdoor Lighting Accelerator will demonstrate practical and effective best practices to accelerate the adoption of high-efficiency outdoor lighting and improve system-wide replacement processes at the municipal level. Cities will work together and with DOE to drive analysis, secure funding, and install outdoor lighting s [..]

The CALiPER (Commercially Available LED Product Evaluation and Reporting) program was launched by DOE in 2006 to address a need for unbiased, trusted product performance information in the early years of SSL. CALiPER testing and analysis, conducted by accredited test labs using industry-standard test procedures, helped to discourage low-quality pro [..]

Biological rhythms that repeat approximately every 24 hours are called circadian rhythms. Light helps maintain the circadian clock, and researchers are working to better understand how lighting can support or disrupt circadian rhythms.

Indicates how warm/cool light is. CCT is measured in Kelvin (K). Higher values (>5,000K) indicate a cooler/bluer light color; lower values (<4,500K) indicate a warmer/more orange light color.

Indicates the light’s ability to render colors across the spectrum.

The ability for devices to coexist in a system without corrupting, interfering with, or hindering each other’s operations.

Light control is allows users to regulate the level and quality of light in a given space for specific tasks or situations by integrating dimming, daylighting detection, networkability, task tuning, and more.

The Design Lights Consortium (DLC) drives lighting market innovation by providing information, education, tools and technical expertise. Since 2010, the DLC has administered the Qualified Products List (QPL), a resource that distinguishes high quality, energy efficient commercial LED products. Read more at www.designlights.org.

A light fixture (also known as a luminaire) includes one or more lamps, a fixture body, and a light socket.
