Though the worst impacts of the pandemic are over, illness and absenteeism resulting from airborne viruses continues to cost U.S. businesses over $200B annually, reduce student learning and achievement, and exacerbate public health and education inequities. As the building industry considers how to address these costs, ASHRAE has committed to develop a new building design […]

Light at night provides the benefit of increased visibility and the associated impressions of safety and security, but how might we reimagine light at night not only as innovation in technology, but innovation in thought to address the needs and desired outcomes for the community in which it is installed? Let’s discover the stakeholders, influencers, […]

Temporal light modulation (TLM, or flicker) is an increasing phenomenon in indoor, outdoor, and vehicular applications, due to the widespread adoption of LED sources. Most LED lighting systems don’t produce problematic TLM, but for those that do, there has been a delayed recognition that certain TLM waveform characteristics and viewing conditions can result in distraction […]

A lot has changed since the first “illuminating engineers” shared ideas for how lighting could make the early 20th century streets safer; we know more about light, we know more about vision, we know more about humans, we know more about behavior, and we know more about darkness.  However, the complicated relationship between science and […]

There are many different types of hospitality projects, and effective lighting is consistently an important design tool to enhance the guests’ overall experience. It is often the first feature that guests notice and is the element that creates that all-important long-lasting positive impression that may influence guests’ opinions about the quality, character, convenience, and charm […]

Join us for a special 1-hour Webinar dedicated to learning more about the IES ANSI process; why it is important to the lighting community, how it works, and an opportunity for Q&A.

This webinar will examine the role common LED drivers may play in producing flicker and its associated health concerns. How may these electronics be modified to produce a better TLM waveform? We will review emerging research and best practices for both fixed-color and color-tunable systems.

Museum lighting has a long history of being controls intensive. Striking the balance between the desire to preserve the work being shown and the guest’s ability to SEE the work can be complicated. Lighting control systems are advancing, making that balance easier to find while also giving designers new tools and providing data to curatorial […]

IES Lighting Measurements (LM) 83-23, Approved Method: IES Spatial Daylight Autonomy (sDA) and Annual Sunlight Exposure (ASE) recently underwent significant revisions and ANSI certification. LM-83-23 describes the IES approved method for computing annualized climate-based metrics for daylight sufficiency (sDA) and for excessive sunlight exposure in buildings (ASE). It provides a common reference standard for daylighting […]
