  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 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 [...]

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 [...]

In late January, LightNOW posted about signs of trouble ahead for the Multifamily real estate market. There are now indications that trouble has arrived. Apartment loans at least 30 days past due or in non-accrual have jumped 81%. Banks are increasingly taking losses on apartment loans. This will likely lead to distressed selling, as well [...]
