The DesignLights Consortium’s (DLC) new report, Energy Savings from Networked Lighting Control (NLC) Systems, estimates average lighting energy savings of 47% resulting from installation of networked lighting control systems. The report indicates high potential energy savings for networked controls, supports layered control strategies as a means to maximize savings, and may be used to justify new and larger utility rebates. Craig DiLouie, LC, CLCP breaks it down in this month’s featured article.

Most commercial building energy codes require automatic lighting shutoff. This common-sense strategy also adds value to lighting upgrades in existing buildings. Remote switching is one method, with an option being switches residing in a metal cabinet-type enclosure called a panel. This panel can serve as the backbone for a complete energy code-compliant control system that responds to a wide range of control inputs for indoor and outdoor lighting control. It is typically sold as a new complete unit, though panelboard retrofit assemblies are available.
This article describes common panel-based lighting control systems.

Republication of Postings from the U.S. Department of Energy (DOE) Solid-State Lighting Program by Jim Brodrick, SSL Program Manager, U.S. Department of Energy A new GATEWAY report on a trial installation of tunable-white LED lighting systems in three Texas classrooms provides valuable insights into the use of this technology in a real-world setting. While reducing […]
LD+A recently published an article by the California Lighting Technology Center’s Cory Jackson, discussing why commercial lighting remains sparse in demand response programs and what can be done. She writes: After nearly two decades of support and research focused on automated demand response (ADR), lighting remains underutilized as a demand response resource. Beginning in 2007 […]
In “Connectivity is The Key,” LD+A lighting control columnists Gary Meshberg, LC (chair, Lighting Controls Association) and Craig DiLouie, LC (education director) describe the revolution in lighting controls occurring in the area of connectivity and what this means for the future of lighting. The authors write: While basic connected lighting capabilities have been available for […]
In May 2016, the DesignLights Consortium® (DLC) released V.1.0 of its Networked Lighting Control Systems Specification, which formed the basis of a new Qualified Lighting Products List (QPL). The intent was to provide utilities and energy efficiency programs a resource to qualify networked lighting control systems so they could be covered in commercial sector lighting […]
Guest Post by Kevin Willmorth Flicker presents itself in several forms, each with its own cause. For lighting decision makers, avoiding flicker requires understanding what causes it and what can be done to avoid it. For a good understanding of what flicker is and how we see it, NEMA’s position paper TLAs-2015 Temporal Light Artifacts […]
