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

That’s one small step for man, one giant leap for mankind – The last time human beings headed moonward was on the Apollo 17 flight that launched Dec. 7, 1972—before any of the Artemis II crew members were born. Today’s crew will not land on the moon—they won’t even orbit the moon. But they will whip around the lunar far side, on a shakedown mission test-flying the Orion spacecraft. This is essential preparatory work for achieving NASA’s bigger lunar goals. Next year there will be another test flight in low Earth orbit during the flight of Artemis III, followed by up to two moon landings by Artemis IV and V in 2028, and annual landings thereafter. Unlike the Apollo program, Artemis aims not just for the so-called flags-and-footprints model of short, one- to three-day stays on the moon, but for a long-term presence at a long-term moon base in the south lunar pole, where deposits of ice can provide drinkable water, breathable oxygen, and oxygen-hydrogen rocket fuel. Very much like the Apollo program, Artemis finds itself in a closely watched moon race, not with the old Soviet Union this time, but with China, which has announced its intention to have astronauts on the moon by 2030. The U.S. is not going it alone this time, however. While Apollo was an entirely American enterprise, Artemis flies under the flag of 60 countries, signatories to the Artemis Accords, an international pact whose members vow to support the peaceful exploration of space and contribute money, modules, and astronauts to the Artemis cause.
