The Value of Dimming by Levin Nock

It’s easy to see the energy benefits of dimming: the more an LED fixture is dimmed, the less electricity it uses. In terms of future-proofing the energy savings of lighting projects, the longevity of LED products makes it paramount to strengthen requirements for dimmability and other lighting control strategies now, since LEDs installed today are expected to work for a decade or more. The latest version of the DesignLights Consortium’s (DLC) Solid-State Lighting (SSL)Technical Requirements stresses the importance of dimming as a way to increase energy savings, while allowing occupants of offices, conference rooms and other spaces to adjust light levels to their comfort or needs. All LEDs are inherently able to dim and nearly 100% of DLC-listed fixtures are dimmable. Expanded adoption is the necessary next step to capturing the benefits of dimming. The Value of Dimming | EC&M

TRAINING: How to Design a Lighting Control System by C. Webster Marsh and Craig DiLouie

Based on EE105: Lighting Control System Design, a new course in the Lighting Controls Association’s Education Express program provides detailed information about designing an effective lighting control solution. In Part 1 of this Lighting Controls System Design series, we learned about key documentation including the Content Intent Narrative (CIN), Sequence of Operations (SOO), and Owner Project Requirements (OPR). The next step in design development in Part 2, is to turn these requirements and conceptual design into a realized design. In Part 3 of this series on how to design a lighting control system, we will discuss installation and post-occupancy. You will learn about bidding, responding to questions from installers, reviewing submittals and defending your design, following-through with the installation of the equipment, functional testing, training essential staff, and ultimately ensuring the owner is satisfied. How to Design a Lighting Control System

DLC Draft 1 Horticultural Technical Requirements V4.0

The DesignLights Consortium (DLC) has released their Draft 1 Horticultural Technical Requirements V4.0. The draft proposes three updates:

  • Efficacy increase: Hort V4.0 proposes to increase the efficacy threshold to 2.5 μmol × J-1, which is an 8.7% increase over the Hort V3.0 threshold. This will set the DLC efficacy threshold for LED-based horticultural lighting at more than 45% above the most efficacious non-LED option.
  • Removal of lamp categories: Hort V4.0 proposes to remove eligibility for lamps. This decision was made based on low application numbers in lamp categories.
  • Clarifications to various requirements: A variety of clarifications are proposed throughout Hort V4.0, including for definitions of key terminology and for certain testing requirements.

The Draft 1 Horticultural Technical Requirements V4.0 document is available here.

LED Bollards with Selectable Wattages by naturaLED

naturaLED® has LED Bollards with customizable wattage capabilities. 8″ diameter for easy retrofits and 4 configurations. Perfect for your area lighting, pathway, or perimeter lighting projects! BLD bright pathway lighting is important for the safety of pedestrian foot traffic. Ensuring that sidewalks and pavement are well-lit reduces the risk of people tripping and falling. The superior quality of our DLC Bollard light fixture provides glare-free lighting that replaces 100-watt metal halide fixtures and produces 2000 lumens. led bollards – naturaLEDWatch the Frank Grobmeier video: Discover the Difference between Pathway & Bollards (youtube.com)

Artificial Intelligence (AI) for Hire – While most of us have heard the term artificial intelligence, few could predict the explosion of GenAI technologies in the public sphere over the last two years. In the work setting alone, Microsoft and LinkedIn reported that “75% of knowledge workers use AI at work” and “66% of leaders say they wouldn’t hire someone without AI skills”.                 

So how did this all happen:

1956, August: At the Dartmouth Conference, researchers discuss creating machines capable of intelligent behavior and the term “Artificial Intelligence” is introduced.

2017, June: Google researchers introduce the Transformer architecture, the foundation for generative AI (GenAI) models. (GPT = Generative Pre-trained Transformer)

2022, November: OpenAI unveils ChatGPT, a conversational GenAI model, marking a tipping point in public access and accelerated adoption.

2024 NOW: Commercialization is accelerating. Globally, the GenAI solutions market is expected to exceed $50 billion by 2028 with over 60,000 GenAI companies already doing business (Horban, 2024).  The biggest tech/communications companies are all involved in a very big way to drive and influence our lives now and in the future with their GenAI models:

  • OpenAI’s ChatGPT
  • xAI’s Grok
  • Google’s Gemini
  • Microsoft’s Copilot
  • Anthropic’s Claude
  • Apple’s Apple Intelligence
  • Meta’s Llama
  • Coming: Orion by OpenAI
