A lot has changed since the first “illuminating engineers” shared ideas forhow lighting could make the, early 20th century, streets safer; we know moreabout light, we know more about vision, we know more about humans, weknow more about behavior, and we know more about darkness.
All those things we know make the lighting design tasks easier. At the intersection of free-will and standardization, however, the lighting design professional has the expertise to facilitate best practice design approaches to accomplish what we really want – to enjoy the benefits of both light and darkness.
In this presentation, the speaker will explore the challenges of writing – or interpreting – ordinances and standards related to outdoor lighting and will suggest ways to improve the relevance and effectiveness of these tools. He will make suggestions that every lighting practitioner, architect, and urban planner can use to facilitate the process to arrive at best practice lighting solutions for the outdoor environment; language, approaches, tools, tips, and thoughts that you will take back to your desk and implement immediately.
Darkness presents both challenge and joy to the art and science of lighting design – We have the expertise to express this natural tension with our designs as we create the places we want to be for the people with whom we want to be.

Span wire or catenary lighting can create decorative and aesthetically pleasing results for lighting installations. In the design of poles to support these applications, consideration must be made as the resulting loads are generally much greater than a typical luminaire only design. The following topics will assist lighting designers and specifiers in the design process: background of catenary loads, influencing factors on magnitude of loads, information required for pole design, pole and wire attachment characteristics.

The goal is to provide clarity and assistance for Manufacturers, Specifiers and Customer/End Users on the navigation and understanding concerning the detailed BABAA requirements.

This presentation will be an informative look at the comprehensive analysis of the data to provide valuable statistical insight into the common vulnerabilities and potential risks of failures these structures can experience. By unveiling patterns and degradation trends in the data, the presentation will provide valuable proactive and highly informative, data driven strategies for both initial specification and on-going maintenance to ensure we continue to illuminate our public spaces safely, reliably, and cost effectively.

Cutting energy costs and reducing carbon footprint are the primary reasons why most utilities and local governments upgrade streetlighting with LED’s and wireless controls. However, tremendous operational efficiencies also can be achieved by pairing smart streetlights with streetlight operations software — a step that so far is often overlooked. Georgia Power and TerraGo review hands-on lessons learned from managing the deployment and maintenance of smart streetlights, with and without streetlight operations software.

The DC Smart City Street Lighting Initiative (DCSL) aims to revolutionize Washington, D.C.’s lighting by upgrading 75,000 streetlights with LED technology and a remote monitoring system. This initiative addresses the need for cost-effective, eco-friendly lighting while setting a precedent for sustainability and innovation.

This presentation will review a multiyear project between Georgia Power and the City of Atlanta. We will review the original audit, its findings, purchase negotiations and upgrades to the City owned system as well as the addition of new LED lighting around the City that has both enhanced the visibility across the City and helped reduce crime. We will share before and after highlights.

In the old world of lighting, traditional lighting systems were characterized by limited functionality and control options. Lighting fixtures operated independently, lacking the ability to communicate with each other or with external devices. Maintenance and troubleshooting were often challenging, relying on manual inspections and reactive responses to issues.
However, the advent of smart lighting technology, particularly DALI (Digital Addressable Lighting Interface), has ushered in a new era of illumination. DALI D4i represents the pinnacle of this evolution, offering a sophisticated data bus that enables seamless communication between lighting fixtures and control systems. This data bus not only facilitates precise control over individual fixtures but also enables advanced features such as diagnostics, asset management, and support for integrated controls and sensors. With DALI D4i, lighting systems have become intelligent and interconnected ecosystems that can phone home.

“BUG” ratings (Backlight-Uplight-Glare) were introduced as a new method of classifying an outdoor luminaire and became entrenched over the past couple of decades in codes, luminaire qualification programs, and lighting ordinances. While simple metrics are easy to use, it’s important to know the limitations of an equipment-level metric. Are BUG ratings the right tool to reduce light pollution and ecological impact when we humans are adding light to the outdoor nighttime environment?

The systems we design can be dangerous because they use electricity. This presentation will let participants know where they can look for the standards that will keep the maintenance and contractor personnel who work on and around those systems safe.

This seminar will cover the implementation of the DALI-2 D4i protocol for outdoor intelligent lighting, specifically focusing on Memory Bank 1. Participants will gain practical insights into programming and retrieving device information, configuration settings, and luminaire-specific data for asset management and ongoing maintenance.

This presentation explores how solar lighting addresses key challenges faced by utilities and highlights its transformative potential for U.S. utilities.

Additionally, we’ll explore the regulatory landscape, highlighting how utilities can navigate policies, incentives, and subsidies to advance solar lighting adoption. The presentation aims to equip participants with actionable knowledge for effectively advancing sustainable utility solutions and integrating solar lighting into their operations

In recent studies at VTTI we have considered the impact of adapting lighting to the needs of the roadway user. This includes development of an algorithm for when the lighting should be dimmed based on traffic and pedestrian volumes and time of day. An assessment of the impact of the dimming including changes to crash rate, crime rate, public perception and energy usage was also considered in the studies.

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 to address the needs and desired outcomes for the community in which it is installed.
Let’s discover the stakeholders, influencers and motivations to expand light from a “footcandle requirement” to a beacon for community, and a connector of people and spaces.

LED adoption has penetrated ~50% of outdoor lighting in the U.S. and potential energy savings with streetlight controls is substantial, driving cities and utilities to shed light on their own energy bills. Lighting represents ~40% of a municipal’s energy spending, but without monitoring and controls, costs must be estimated with flat rate tariffs, leaving cities in the dark about the true costs of their lighting systems. As the adoption of smart city sensors under industrial IoT (IIoT) streetlight canopies also grows, lack of visibility into these assets affects operations and drives energy consumption up–with cities and utilities footing the bill. Leveraging the capability of smart lighting controllers enables the street light canopy as a network platform for sustainability, digitalization, and public safety services, ultimately accelerating value and improving quality for communities of all sizes.

The City of Bee Cave has long valued its Texas hill country terrain. With a population boom and amenities including a large competitive youth multi-sport complex and a planned 25-acre outdoor entertainment development, the City worried about losing its esteemed night sky. This presentation explores the journey to successfully being recognized by the International Dark-sky Association as an International Dark Sky Community.

This presentation examines a 7-year case study on the maintenance of over 300,000 unmetered streetlights within 99% accuracy between the Utility and the Customer bill. Join us as we uncover valuable insights, including lessons learned in data integrity, best practices in handling historical records and process enhancements, and successful business approaches that utilities and customers can sustain.

Communities, advocates, and local governments are seeking lighting solutions that allow them to meet outdoor lighting ordinances, achieve their decarbonization goals, and minimize environmental harm. “Amber” LEDs —especially phosphor-converted Amber LEDs—and warm white LEDs are gaining popularity as a strategy for mitigating light pollution despite lacking standard lighting specification language that minimizes mis-selection and misapplication. We will compare light pollution and performance attributes and give an update on new and revised standards for non-white LEDs.

There have been reports of excessive color changes in streetlights resulting in a change from white to colors that are well off the Planckian Locus (e.g., purple, blue). This paper presents an examination of 28 LED light engines taken from field replacements that exhibited visually excessive color changes. These LED light engines were characterized using a combination of techniques, and the root cause of the gross color change was identified and will be discussed.
