Available in new construction luminaires and retrofit trims and kits, LED offers the benefits of directional light output, high efficiency and life, good lighting quality, and controllability in downlighting. Click to read this article about trends in this category.

A new LRC study investigated the effectiveness of Apple’s Night Shift screen setting for lessening the impacts of nighttime iPad use on melatonin suppression, a marker of the circadian system. The study found changing screen color alone is insufficient for limiting the impact of portable electronic devices used at night, and that screen brightness should also be reduced.

The lighting industry continues to undergo historic change marked by extraordinary trends enabled by rapid adoption of LED lighting. Connectivity and networked control, the Internet of Things, lighting and health, restrictive energy codes, and rebates are all driving change. For electrical contractors that compete based on lighting expertise, this presents the challenge of reviewing one’s skillsets and learning what needs learning to remain competitive. In this informative roundtable, ELECTRICAL CONTRACTOR talked to six lighting industry experts to find out what impact these trends are having and where they’re going.

The Illuminating Engineering Society’s (IES) 2018 Research Symposium, themed, “Light and Human Health,” will be held April 8-10, 2018 at the Crowne Plaza Atlanta and SimTigrate Design Lab in Atlanta, GA. Registration is now open.

Hubbell Lighting’s Remedi™ LED multi-function bed light features four distinct optical compartments to eliminate the need to physically move any portion of the luminaire housing to utilize key lighting functions. This is a radical departure from the traditional solutions and an innovation that allows the healthcare professional to more efficiently accomplish critical patient evaluations, eliminates a potentially hazardous activity over the patient, and reduces the chance of contamination.

The lighting industry continues to explore potential benefits of lighting solutions that optimize human health. Studies indicate light has physiological effects that go beyond vision. In recent years, the industry has focused on the impact of light on the human circadian system, and how electric lighting choices thereby can affect circadian health. Mariana G. Figueiro, PhD, Professor and Light and Health Program Director at the Lighting Research Center at Rensselaer Polytechnic Institute, says there are four major factors in designing a lighting solution that optimizes circadian health.

I recently had the pleasure of interviewing Scott Roos, VP Design, Downlight, Accent and Trac Products, Acuity Brands Lighting. The topic: trends in LED downlights. I’m happy to share his responses with you here.

In this republication of a recent Postings, SSL Program Manager Jim Brodrick revists last year’s AMA community guidance on streetlighting and sets the record straight on sky glow and blue light.

DOE has released a new report on a tunable lighting system installed at the Swedish Medical Behavior Unit in Seattle that sought to leverage biophilic design principles.
