  DMF Lighting, an architectural lighting manufacturer of modular LED downlighting systems, has expanded its 2-inch X Series modular downlighting collection to include Cross Beam Total Internal Reflection (TIR) Optics; a 500-lumen Ultra-Narrow light engine module; Pinhole and Hyperbolic trims; and extension collars for installation in thicker ceilings. The uniquely designed Cross Beam TIR Optics reducing glare [...]

  Yesterday’s LightNOW post was about the Design Lights Consortium DRAFT Networked Lighting Control v5.1 standard (DLC NLC5.1). This post is about another NLC industry standard, the Bluetooth NLC standard. In September, 2023, the Bluetooth Special Interest Group (SIG) announced the completion of Bluetooth Networked Lighting Control (NLC), the first full-stack standard for wireless lighting control. [...]

  The Design Lights Consortium (DLC) has released their draft of v5.1 Networked Lighting Control technical requirements (NLC5.1). NLC5.1 is a minor revision that contains updates to the policy’s energy monitoring and cybersecurity requirements. There will not be a delisting associated with the policy. Existing listed v5.0 NLC will continue to be DLC listed. Energy Monitoring Updates: [...]

Three recent announcements involve biomimicry to improve propeller and wind turbine designs. They all raise the question of whether these types of innovations could make their way to ceiling fan blade designs? Judge for yourself. ABB Dynafin Propeller Switzerland’s ABB Marine introduced a multi-blade Dynafin propulsion concept (see above). The innovative concept mimics the motions [...]

The 4th annual ArchLIGHT Summit has opened attendee registration. The conference and trade show event will be held September 17-18, 2024, at the Dallas Market Center. It is a specifier-centric event for lighting designers, architects, engineers, and interior designers. You can register and view the full schedule of events, here. Attendees will have access to [...]

  The Illuminating Engineering Society (IES) has published three new lighting standards: ANSI/IES TM-40-24 IES Technical Memorandum: IES Method for Determining Correlated Color Temperature (CCT) and Distance from the Planckian Locus of Light Sources Prior to the publication of this Technical Memorandum, no method for calculating CCT (nor Duv) has been formalized by a relevant [...]

  On April 12th, the U.S. Department of Energy (DOE) issued a final rule for General Service Lamp (GSL) standards. The new standards will raise GSL efficacy requirements from the current 45 lpW (aka the backstop), up to 83 – 195 lpW, depending on lamp type and lumen output. The previous 45 lpW backstop was [...]

  IES & DOE Research Symposium May 15-16, 2024 Held in Portland, OR, topics will include: research trends for next-generation lighting tools, new recommendations & methods to evaluate health impacts, innovative approaches to environmental stewardship & support of sustainable lighting practices, novel tools for post-occupancy evaluations, and design for resiliency. Register here. Lighting Education Tour [...]

  The Federal Communications Commission (FCC) launched a voluntary cybersecurity labeling program for wireless consumer Internet of Things (IoT) products, including lighting, on March 14, 2024. The program is called the U.S. Cyber Trust Mark Program and it is designed to help consumers make informed purchasing decisions, as well as incentivize manufacturers to meet higher [...]
