Seeking Standardization: Open Systems Are Becoming More Relevant by Craig DiLouie
As lighting systems evolve from simple illumination devices into connected infrastructure, the industry is placing more emphasis on open, interoperable standards. While many control platforms still rely on proprietary hardware and software, open standards are becoming increasingly relevant. A significant player in standards is Zhaga-D4i (zD4i). It combines a standardized plug-in interface for sensors and communication modules with a common digital language for data exchange. For electrical contractors, this framework can simplify installation, improve upgradability and create new opportunities for offering connected lighting solutions. To address this, Zhaga introduced Book 18 in 2018. Now in its fourth edition (released in 2025), Book 18 defines how a smart node physically attaches to an outdoor LED luminaire, receives power and exchanges digital information with the driver. In effect, Book 18 serves as the socket standard for modern connected outdoor lighting. Around the same time, the DALI Alliance expanded its DALI-2 standard to better support internet of things (IoT) and luminaire-level control. With Zhaga’s Book 18 managing the physical and electrical interface and the DALI Alliance’s D4i managing the digital handshake, the two organizations partnered to create the zD4i product certification.

Elon Musk recently announced what seemed like an odd pairing of his companies: SpaceX was acquiring xAI, the artificial intelligence firm that also owns the social media platform X. The merger combines a highly profitable rocket company with an AI startup that is burning through billions of dollars as it competes with OpenAI and other rivals for dominance in artificial intelligence. The merged companies are valued at $1.25 trillion. That is higher than recent separate valuations of SpaceX at $800 billion and xAI’s holding company at $230 billion. IPO shares are expected to price at roughly $525. Aside from the financial benefits, there are technical reasons. Musk has sketched out a futuristic plan that involves sending up to a million satellites — called data centers — into an orbit, where the sun could power them all day and night while they do artificial intelligence computations. 
General-purpose robots could be useful in a range of construction activities, from moving heavy concrete blocks to welding and plumbing. Although these robots come in various forms, humanoids—those that resemble people in size and shape—attract the most attention. Humanoids are still relatively early in development, but they could potentially transform industries if developers and other stakeholders can overcome technological, regulatory, financial, and operational hurdles. Although humanoids are not yet a fixture at construction sites, they represent a potentially transformative solution to the productivity crisis. Their power comes from embodied AI, a technology that enables real-time decision-making. Rather than waiting for full-scale deployment to become a reality, forward-looking construction leaders should begin preparing now for a future in which humanoids and humans work together.Those who prepare now will be best positioned to seize the opportunities ahead.
