Retrofit Lighting Products Trend Towards Wireless Control
New luminaires and components for the retrofit market increasingly feature high efficiency and integrated wireless controls. Products like the Stella 40W LED Panel offer high efficacy for energy compliance, while wireless electronic ballasts such as the FLS-H enable control via Zigbee and smart devices without complex rewiring. This trend supports more user-friendly and less disruptive smart-ready upgrades in existing buildings.
- [The WELL Building Standard](https://vertexaisearch.cloud.google.com/grounding-api-redirect/AUZIYQEWmGR_pMhGPBc-I-BIGFOUuGCxiScwc7HSZvvJn9GRaYINyT0gXjR6F8gETyWmBcDybBZAK_dpX_O7PViSYJ4ECdzIETFGQPbry0FdybKy2SB7YKnrNRJ2Kl6NX7X0Do4OAO6znE2DUb0IoD81E-zR8JTXZp6mxnvWz3H1iP6hqPrkIdgnwgg8EYyqYO7768bXTwUHLWA21af5KLY5rnSWQD_cjw==) utilizes Equivalent Melanopic Lux (EML) to measure light's impact on human circadian rhythms, requiring at least 150 EML for a minimum of four hours daily from electric light to support natural biological processes. This is achieved through tunable white LEDs that can adjust spectral power in the 460-480 nm blue region to trigger melatonin suppression, mimicking natural daylight cycles. - To simplify interoperability between smart lighting devices from different manufacturers, the Matter protocol, developed by the Connectivity Standards Alliance, operates on standard IP-based networking technologies like Wi-Fi and Thread. This approach reduces latency and can lower idle power consumption in smart bulbs by up to 20%. - AI-driven lighting control systems can reduce a building's lighting energy consumption by 8% to 40% by using sensors and predictive algorithms to adjust for occupancy and daylight availability. In commercial buildings, where lighting can account for nearly half of all energy use, these systems offer significant operational cost savings. - The DALI+ specification enables the use of the established DALI lighting control protocol over wireless and IP-based networks like Thread, Wi-Fi, and Ethernet. This allows for the integration of wired DALI-2 systems with wireless devices via bridges, creating highly scalable and flexible lighting control systems. - Circular economy principles are being applied to luminaire design, emphasizing modularity, reparability, and the use of recyclable materials like aluminum and bio-based plastics. This "design for disassembly" approach extends product lifecycles and reduces waste, with some manufacturers exploring "lighting as a service" models where they retain ownership and responsibility for maintenance and upgrades. - Zigbee Green Power technology enables wireless, battery-free switches and sensors that harvest kinetic energy from a button press to transmit a signal. This eliminates the need for wiring or batteries, offering greater flexibility in control placement and reducing maintenance. - Imperceptible high-frequency flicker from some LED and fluorescent lighting can cause eye strain, headaches, and fatigue, with one study in a London office finding that reducing flicker halved these symptoms. The WELL Building Standard includes flicker management as a key component of electric light quality. - For human-centric lighting, the Color Rendering Index (CRI) alone is insufficient; an R9 value of 50 or higher is often specified to ensure accurate rendering of deep red tones, which is important for the appearance of skin tones and objects. Advanced tunable white systems now use LEDs with broader spectral power distribution to more closely replicate the non-visual, biological effects of natural sunlight.
