In the 1890s, scientists experimenting with sunlight and filters discovered that a narrow band of the visible light spectrum (400–405 nanometers, associated with violet) was effective at killing bacteria. The idea of applying...

Networked lighting controls connect luminaires in a programmable system to offer exciting and robust capabilities. Connected lighting packages of luminaires and controls are increasingly touted as “internet of things (IoT)...

Well-suited to financing lighting upgrades in large projects, lighting as a service (LaaS) is a lighting industry business model in which the owner purchases light rather than the hardware that delivers it. The owner pays a...

Active core sunlighting is the subject of a new design guide (DG-31-18) published by the Illuminating Engineering Society. With this approach, sunlight is captured using solar-tracking optics, delivered deep within the...

Emergency lighting is lighting that stays on or automatically turns on to facilitate a building’s safe evacuation when it suffers a power outage. There is a trend of using luminaires as both general and emergency lighting,...

Electrical contractors consider themselves highly influential in lighting-equipment selection for both new construction and retrofit projects. That’s one key finding from the 2019 CII Lighting Trends Survey, which ELECTRICAL...

Connected lighting and the internet of things (IoT) offer exciting potential for energy and operational efficiencies, but attention must be paid to ensure these systems are safe from hackers. While the owner bears the brunt...

In 2018, the California Lighting Technology Center (CLTC) published “Daylight Harvesting for Commercial Buildings Guide,” a best practices guide to designing daylight harvesting systems. While focused on compliance with...

In May 2018, the U.S. Department of Energy (DOE) released “Advanced Lighting Control System Performance: A Field Evaluation of Five Systems.” This report evaluated field installations of five advanced lighting control systems...

A 2017 DesignLights Consortium report analyzing performance data from more than 100 installations found that networked lighting controls produced an average 47 percent lighting energy savings. The biggest value in connected...

LED technology, connectivity, intelligence and the internet of things continue to drive change and product development in the historically staid lighting industry, where disruption has become the norm. For electrical...

Light Fidelity (Li-Fi) is a wireless communication technology that uses visible light to transmit data at very high speeds. It is another potentially transformative capability of LED lighting. According to Global Market...
