DLC Updates its Technical Requirements for LED-Based Horticultural Lighting

William Attardi on March 14, 2025

A new version of the DesignLights Consortium’s (DLC) Horticultural Lighting Technical Requirements released today strengthens efforts to improve the efficacy and quality of LED products used in the controlled environment agriculture (CEA) industry. Taking effect April 18, 2025, the DLC’s new requirements come at a time of burgeoning growth in the CEA sector. Valued at $7.8 billion last year, the global CEA market is expanding at a compound annual growth rate of 12.2 percent and expected to reach $22 billion by 2033, according to a February 2025 market research report. With lighting being the largest operational expense in CEA facilities, there are significant opportunities to increase energy efficiency and cost savings with the right lights.

Sollum Technologies and Leaficient Introduce the First Plan-Responsive Dynamic LED Lighting Solution

William Attardi on March 8, 2025

Sollum Technologies and Leaficient are pioneering a breakthrough technology that redefines how LED lighting adapts to plant growth. Today’s traditional lighting strategies rely on Daily Light Integral (DLI) as the primary metric for optimizing plant growth, based on the premise that plants absorb and use light with the same efficiency throughout the day and at all growth stages. However, recent research has shown that plant productivity can change significantly based on a myriad of factors relating to the environment, resources provided and internal biological processes. In response, Sollum and Leaficient are collaborating to develop the first closed-loop, plant-adaptive dynamic lighting system, which adjusts lighting in real time based on plant productivity and growth rates.  [News] Sollum Technologies and Leaficient Introduce the First Plan-Responsive Dynamic LED Lighting Solution – LEDinside

The First Edition of the Encyclopedia Britannica Is Published on Dec. 10, 1768  The Encyclopedia Britannica, the oldest continuously published and revised work in the English language, was first made available to the public in Edinburgh, Scotland. This monumental work, which would go on to become a cornerstone of knowledge, marked the beginning of a publication that has influenced generations of scholars, students, and curious minds around the world.  The Encyclopædia Britannica was the brainchild of Colin Macfarquhar, a Scottish printer and bookseller, and Andrew Bell, a Scottish engraver. Together, they sought to create an authoritative, comprehensive, and accessible work that would encapsulate the growing body of knowledge of their time.  What began as a small printing project in Edinburgh grew into one of the most influential reference works in the world, providing access to knowledge and intellectual insight for generations, helping to shape the way we think about history, science, culture, and the world around us. Today, the Encyclopedia Britannica is regarded as one of the most influential reference works in the world. Our personal library to help us learn.  I hear  something better is coming along………
