This article presents a review of the methods used for subjective evaluation of discomfort from glare, focusing on the two procedures most frequently used in past research – adjustment and category rating.
My blog post from April 1, 2020, entitled Lessons Learned from Living Lab describes a research project about retrofitting existing spaces with networked lighting control systems (NLCs). It contains recommendations on how to avoid typical of problems that may be encountered on an NLC install. This post will elaborate on some of those “lessons” and recommendations.
For way too long, site, area, and roadway calculations focused on performance, light levels, and uniformity. Pole spacing has been a top consideration, propelling optical design to new heights, but also pushing luminous density in higher angles, promoting the use of glarier products, and driving light levels up to an excessive and unnecessary amount.
Heliospectra announced the release of two new guides with focus on energy-savings, incentives, and rebates. The free guides provide a detailed overview of the type of rebates available by state and province and the payback one can expect in 2021.
In Part 1 of this interview with Leora Radetsky, we covered smart lighting, customizability, and COVID-19 possibilities. For Part 2 we are diving into indoor agriculture, how utilities are helping drive LED adoption with incentives, and challenges in the LED market.
As we navigate ‘the summer of COVID-19’, thoughtfully designed outdoor spaces are more important than they’ve ever been – and lighting can play a major role in creating them.
If you intend to sell your lighting products in North America, please note that many U.S. and Canadian utilities rely on the DesignLights Consortium (DLC) Qualified Product List (QPL) to provide utility rebates to end customers of professional applications.
Dave Hiemstra (CLCP, CTR) is the Controls Group Manager with Optics Lighting, he presented on Designing & Deploying Budget Friendly, Code Compliant Lighting Controls as part of the Alberta Electrical Alliance Electrical Learning Expo.
In a recent article on LEDs, we covered numerous topics and questions to help consumers buy the right bulb for their needs and be happy with their purchase. But LEDs are not only for residential use. In fact, some of the first applications/uses of LEDs (after indicator lights) were for exit signs, traffic lights, taillights, and refrigerated case lights.
Building a control system for a modern lighting installation can seem like an impossibly complex task. To simplify it, a systematic approach to understanding the needs of the design, facility, and user can be employed. In this white paper, we aim to define the questions one must answer to construct an appropriate control system.
The majority of building power distribution systems use alternating current (AC) sourced from a power grid. This significantly influences the design of direct current (DC) appliances including LED light sources and digital controls.
When the North Central Bronx Hospital in NY needed to quickly reorganize several floors to take care of an influx of new patients, Lutron’s Vive Wireless was the ideal solution.
All dimmers are created equal, right? Wrong! All drivers are created equal, right? Wrong! It’s not sufficient to say that you want fixtures to be “dimmable.” There have always been variations in how different dimmers work, and fluorescent ballasts, and more recently LED drivers.
UV-C light is a key component to sterilizing workspaces and equipments. UV-C light kills viruses and bacteria, and has been proven to kill coronaviruses like SARS and MERS. As of June 2020, it is being used all around the globe for this very purpose.
In the 6th installment of this video series, HALO MINUTE, by Cooper Lighting Solutions Bryant Bilal and Maggie Hill discuessed light commercial retrofits.
Industrial environments from warehouses to manufacturing plants are more harsh than typical work environments such as commercial office space.
