  DALS Power Stems are patent-pending, quick-connect stems that simplify pendant installation by delivering both electrical power and structural support without any wiring required. Each stem screws directly into the canopy, no cutting, no splicing, no guesswork. Installers simply select the lengths they need, combining 6”, 12”, and 24” increments to achieve heights from 6 inches [...]

  Smart-home technology is becoming a tougher proposition for consumers because manufacturers increasingly disable or degrade products remotely, when they no longer see them as financially viable, even if the hardware still works. This undermines trust in connected devices, since buyers risk losing key “smart” features—or entire services—after purchase, due to business decisions beyond their [...]

  Quantum sensing uses uniquely quantum properties of light and matter—such as superposition, entanglement, and squeezed states—to measure physical quantities (like phase, displacement, fields, or photon number) with sensitivities that can surpass classical sensors. In photonics, new interferometry-based schemes with quantum light can simultaneously estimate multiple parameters of an optical network (e.g., phase shifts and [...]

  The 2025 NYC Energy Conservation Code (NYCECC) tightens lighting efficiency and control requirements, aligns more closely with the latest NY state energy code, and retains or strengthens prior NYC‑specific lighting provisions. NYC Department of Buildings (DOB) is expected to begin enforcing the new code on March 30, 2026 when updated compliance software is fully available. Filings [...]

  Zaneen’s Lum is a customizable magnetic design system with two types of components: panels with no light, and panels with LED light (all panels must be installed horizontally). The panels are interchangeable and can be configured into multiple designs. There are many finishes available to choose from for Lum, including copper and leather options. [...]

  Energy efficiency in buildings has become the leading infrastructure priority for corporations, driven by cost pressures, regulatory demands, and decarbonization commitments, according to new survey data from Siemens’ Infrastructure Transition Monitor 2025 study. Organizations increasingly see upgrades to existing building stock—rather than new construction—as the fastest, most financially compelling route to cutting emissions and [...]

  Big picture The Department of Labor’s rule (effective March 11, 2024) replaced the 2021 Trump-1.0‑era independent contractor rule and restored a broader, six‑factor “economic realities” test to decide whether a worker is an employee or a genuine independent business under the Fair Labor Standards Act (FLSA). The rule makes it generally harder to classify [...]

  The IES is publishing nine new or revised standards in Q1 2026: ANSI/IES RP-43-25 Recommended Practice: Lighting Exterior Applications Pedestrian-oriented illumination recommendations for the reassurance, safety, comfort, amenity, and enjoyment of people in outdoor environments in lighting zones LZ-1 through LZ-4. This updated standard includes content from LP-2 Designing Quality Lighting and LP-11 Environmental Outdoor [...]

Typical solar lighting is completely off-grid, relying entirely on solar panels and a battery to power the street or area light. A more recent variation that is gaining traction is hybrid solar street and area lights. These lights contain the solar panels and battery, but also have a grid hook up for backup power, when [...]
