GlacialLight Announces New Natural Sunlight of GL-FL35-NL Architectural Floodlighting Series
- GlacialLight, the LED lighting division of GlacialTech Inc., announces the natural sunlight GL-FL35-NL Architectural Floodlighting series. The new lighting fixtures use the SEOUL SunLike CoB to light up objects in their natural colors. The CRI is 97, as well as the CQS (Color Quality Scale) is up to 98. The color fidelity index (TM-30-15 Rf) and color gamut score (TM-30-15 Rg) are close to natural light.

When Nights Are No Longer Dark: Effects of Artificial Light at Night on Agroecosystems
- In recent decades, artificial lighting has become an integral part of the modern world. While the use of artificial light at night (ALAN) greatly benefits people, it often has unintended, negative consequences for wildlife and ecosystems. In particular, the increasing use of LED lighting raises ecological concerns due to its high content of blue light, to which many organisms are sensitive. Dr. Maja Grubisic, Researcher at the Leibniz-Institute and Guest Lecturer at Free University Berlin discusses how ALAN can directly and indirectly influence agroecosystems, with potential consequences for food production and biodiversity. Given the current lack of integrative studies on this important topic, the better understanding of effects of ALAN in agroecosystems is urgently needed.

40-720 W High-Power LED Drivers with 97% Efficiency and up to 660 V Inputs
- The "ICE" family of LED drivers from GWP-Powerland Technology Inc., a Division of FSP-Powerland, is an ultra-high-efficiency LED driver series targeted toward outdoor lighting like horticulture, fishing, sports, and other outdoor LED applications. The output programmability and wire controllability through optional Bluetooth or ZigBee makes the system solution very flexible.

Adaptive, Dynamic and Intelligent Lighting
- Previously, most lighting applications were designed to ensure suitable visual conditions, to support the most demanding visual task anticipated, whilst also taking into account requirements to provide adequate levels of visual comfort and aesthetics. In most cases this was a static lighting solution because the options to change light levels, luminance distribution, or light source spectrum were limited. Tasks, occupants, and needs change from time to time, making control over the lighting desirable, if unattainable. Advanced LED and controls technology make the unattainable possible; now, the key questions are also for CIE how to define the user needs for various applications and how best to set up lighting systems to be adaptive and intelligent in response.

Electrolube Provides Innovative Resin Solution for LED Lens Issue
- Electrolube, the global manufacturer of electro-chemicals, has provided an innovative solution for a complex LED assembly issue. The customer, a leading manufacturer of street lighting and high-bay luminaires in India, had been experiencing problems with the attachment of individual lenses to the elements of multiple LED arrays. The function of these lenses is to scatter or focus light from the arrays, as required, and while some of them are held in position by fasteners, most are secured in place with a locking mechanism. The locking mechanism is perfectly adequate when the luminaire is placed in situ but it tends to loosen during transportation, leading to the lenses becoming detached and causing damage to the array.

Tridonic Adds Casambi Ready RF Modules and Sensors to the basicDIM Wireless Portfolio
- For Bluetooth-based communication between luminaires Tridonic is launching two new Casambi Ready wireless modules in the basicDIM Wireless portfolio. They can be easily and flexibly integrated into existing systems and, with suitable sensors, can offer considerable potential energy savings. It is also possible for the lighting system to be individually adapted.

Hazard or Hope? LEDs and Wildlife
- LpR 70 Article, page 52: The introduction and widespread uptake of LEDs as outdoor lighting has caused no small amount of concern amongst conservation biologists. The prevailing impression that LEDs are always blue-white is well founded as adoption of LEDs for streetlights were invariably high color temperatures and with the deterioration of phosphors the blue wavelengths penetrated even more. But LEDs do have characteristics that differentiate them from other light sources and may allow for the reduction of environmental effects of lighting on species and habitats: direction, duration, intensity, and spectrum. Travis Longcore, Assistant Professor at the University of Southern California's School of Architecture, sheds light on all these aspects.

IoT Ready Alliance Dissolves and Capitalizes on the Breadth of the NEW Zhaga Consortium
- Zhaga and the IoT Ready Alliance are pleased to announce that they have agreed to align their efforts and to proceed as a single organisation under the Zhaga Consortium. The objective is to foster a harmonized, global set of interface specifications for sensor-to-luminaire integration and to remove confusion in the industry.
