This year’s LightFair International, held in Philadelphia May 21-24, was a well-thought-out affair with manufacturers showing a degree of restraint that reflects an evolving understanding of lighting-anchored IoT's potential and limitations. This was a refreshing change from some of the hype of last year’s trade show.
A second trend on display was an increasing number of products that include a tunable correlated color temperature (CCT) capability, especially in the context of human-centric lighting. Such lighting seems to be experiencing a surge in interest as the industry transitions beyond energy savings as the primary driver of adoption.
There were many technical innovations as well, at least one of which may lead to dramatic changes in how spaces are illuminated in the future.
Current (powered by GE)/ Daintree included this display of their sensor portfolio in one easy-to-take-in format. Occupancy sensor data can trigger HVAC operation in a space, as demonstrated by the green light behind the fan (at center). The control system can accept information from other types of sensors including CO2 (bottom center) and pipe leak detection (bottom right).

Eaton Lighting’s Ephesus Lumadapt 8 sports light includes tunable white light from eight larger LED modules and colored light from an additional four smaller modules, one in each corner, combining both capabilities into one lighting product. The product draws 440 watts and delivers up to 50,000 lumens.

Standing in a room lit with Cree’s Cadiant artificial daylight system is completely convincing. The “sun” moves across the ceiling panels during the course of the day, mimicking the appearance of the sky. The panels can be custom configured to the needs of the space; the wall-mounted control panel allows for custom settings as well as pre-programmed profiles for spaces like schools, hospitals, and offices. You can see a demonstration of the system below.
Here are five panels of Cree’s Cadiant artificial daylight system.
