Intelligent lighting control protocols are so complicated, how should OEMs choose?

In a recent discussion, Patrick Durand highlighted that open standards-based lighting control systems can effectively address the concerns of lighting OEMs regarding system complexity, scalability, interoperability between luminaires and control components, and flexibility in indoor commercial applications. As OEMs bid for projects, they are often required to include a compatible lighting control system—typically from a third-party supplier—in their proposals. However, many OEMs have not developed a proactive strategy for integrating lighting control into their offerings. The question arises: Should we wait for a set of global lighting control standards? The answer lies in the confusion surrounding technology choices and supplier selection, especially in indoor commercial and office environments. Most OEMs lack the time, resources, or expertise to evaluate all available lighting control technologies thoroughly. While ZigBee Light Link has become the standard for residential smart lighting, the landscape for commercial and office lighting remains diverse and evolving. Many OEMs prefer to wait for a dominant standard to avoid making early decisions that could lead to obsolescence. One key challenge is the regional variation in lighting control technologies. For example, 0-10V is common in North America, while DALI and PWM dominate in Europe and Japan, respectively. Additionally, building automation systems like BACnet and KNX vary by region, making it difficult for OEMs to rely on a single technology globally. Another factor is the varying complexity of lighting control systems. Some systems use simple occupancy sensors, while others involve centralized management across entire buildings or cities. These differences require different technologies, further complicating the decision-making process. Moreover, the responsibility for selecting lighting control technology often falls on architects, building owners, or managers, not the OEMs themselves. This creates an additional layer of uncertainty for OEMs when developing strategies. Despite these challenges, there are clear criteria that OEMs should consider when choosing a lighting control technology: flexibility, interoperability, simplicity, scalability, and proven performance. Open standards-based technologies offer significant advantages over proprietary solutions. Open systems allow multiple vendors to develop products that work together, giving OEMs greater flexibility and choice. Two major open technologies in commercial lighting are EnOcean and ZigBee. EnOcean, recognized as an ISO/IEC standard, supports wireless switches and sensors without batteries, using energy harvesting techniques. It has a strong ecosystem with over 350 members and 1,300 interoperable products. ZigBee, based on IEEE 802.15.4, offers robust connectivity but often requires gateways for full functionality. While some ZigBee-based systems are interoperable, most still depend on specific gateways, limiting flexibility. Flexibility is crucial, as project requirements can vary widely. Some clients prefer simple, standalone systems, while others want scalable, integrated solutions. EnOcean excels in this area, offering seamless transitions from simple to complex systems without replacing existing infrastructure. Simplicity and scalability are also important. Many end users prefer straightforward solutions without the need for complex network equipment. EnOcean allows for easy expansion into larger systems, while ZigBee typically requires gateways from the start. Finally, proven technology is essential. Building owners and managers prefer mature, reliable solutions. EnOcean has been deployed in over 350,000 buildings worldwide, offering a strong track record. In conclusion, while the lighting control landscape remains complex, open standards-based solutions provide a path forward for OEMs seeking flexibility, reliability, and long-term success in the market. By choosing the right technology, OEMs can better meet customer needs and stay competitive in an evolving industry.
