On Wednesday April 19 and Thrusday April 20, MCEE Expo opened its doors at the Palais des congrès in Montréal to more than 6000 students, contractors, business owners, and many others in the electrical and lighting industries.
LEDs, like all light sources, lose light over time. The term used to describe this is sometimes referred to as lumen depreciation. In lighting design, understanding the rate of this decline over time can help determine the amount of light available at some point in the future. For a little historical perspective, the rate at…
By PRWEB One of the excuses the lighting industry uses to avoid addressing the harmful effects of blue-enriched LED lights at night is “circadian science is not yet mature.” Now a publication in PNAS from Harvard’s Brigham and Women’s Hospital has resolved one of the last remaining contradictions in the science – what color blue is responsible…
November 23, 2022 By Craig DiLouie The DALI Alliance recently extended DALI-2, which standardizes interoperability and control of LED drivers and sensors, with a version that more finely addresses the needs of the Internet of Things, which calls for individual device addressability, connectivity, and two-way data exchange. Called D4i, the standard enables real-time data acquisition for measuring…
November 21, 2022 This video shows a before and after of Premise LED retrofit at the Mayfield Recreation Complex in Caledon, Ontario. Demand Savings: 10.91 kW Estimated Savings (kWh): 47,775 Estimated Total Energy Savings ($): 6,688.49 Simple Payback (years): 3.95
November 9, 2022 In the month since Matter 1.0 was released, Matter momentum has continued to accelerate. Today members showcased their Matter products at a launch event in Amsterdam with a wide array of categories including motion blinds, occupancy sensors, weather devices, smart plugs, door locks, lighting, gateways, platform components, and Matter-based software applications. Since…
The pandemic demonstrated that we don’t know what the future will bring, but we’ve learned to adapt. For example, office spaces changed from rows of individual cubicles occupied on a daily basis to a hybrid layout of shared work desks that accommodates a rotation of employees coming in for a day or two. Just as the spatial needs of many offices changed after the pandemic, so did their lighting needs and energy goals.
Signify introduces a new app, features and products for its WiZ smart lighting system to enhance users’ daily convenience.
The high overlapping nature of various features across multiple mental health disorders suggests the existence of common psychopathology factor(s) (p-factors) that mediate similar phenotypic presentations across distinct but relatable disorders.
In a recent episode of Get a Grip On Lighting Conversation Series, a podcast series that I record with my co-host Ron Kuzmar, we interviewed Norman Russell from NV5. The conversation focused on how lighting controls design has changed and when this change transpired.
The International Ultraviolet Association (IUVA) has released a white paper titled “Far UV-C Radiation: Current State-of Knowledge,” which is a scientific review of Far UV-C technology and the state of the art research featuring key conclusions made through analysis of published literature and collation of expert knowledge.
This new Lighting Measurement (LM) standard, developed by subject matter experts from IES and the International Ultraviolet Association (IUVA), provides guidance for the measurement of UV-emitting LEDs, normally available in the form of an LED package, array, or module.
This briefing summarizes the current state of knowledge about how the widespread and growing use of artificial light at night interacts with six key topics…
Trilliant and Energère recently announced a partnership with the Ville de Granby that will enable the city to increase resident safety, reduce greenhouse emissions and realize overall energy and maintenance savings.
Lumenpulse has introduced new features for their linear, indoor/outdoor favourite, the Lumenfacade Nano.
Harmonization of international standards related to DALI lighting control continues with the publication of the updated ANSI C137.4-2021 standard in North America. ANSI C137.4-2021 builds on the international standard IEC 62386 (which underpins the DALI communication protocol).
