"This year we are introducing the I-Star Circadian System, featuring natural spectrum LED light fixtures integrated with our innovative wireless lighting controls and a programmable interface module," said Melissa Chen, vice president of I-Star Lighting. "The Circadian System lighting enables customers to program the light output of multiple fixtures to automatically adjust over the course of the day, and to wirelessly control their operation from a mobile device."

The I-Star Circadian System is an integrated LED lighting system with the following components:
• A series of 2' x 2' panel lighting fixtures that incorporate natural spectrum LEDs with light output that closely matches the spectrum of natural sunlight.
• Each light fixture connects wirelessly through an I-Star Bluetooth receiver, forming a mesh network that enables all the fixtures in the system to communicate with each other, as well with a central Bluetooth transmitter module and tunable dimmer control.
• I-Star's tunable white LED driver control module provides central dimming and color temperature adjustment for the light fixtures. These modules are available in both linear or rectangular form factors and interface with standard 0 – 10V dimmers.
• An I-Star Bluetooth transmitter mounted in a central location interfaces with standard 0 – 10V dimmer controls and photo sensors to provide a convenient user interface.
• Providing central control and user programmability is the I-Star Gateway programmable interface controller, which enables the user to program the overall lighting system to adjust color temperature and light intensity for specific times over the course of the day. The system can also be programmed to respond to the inputs from light sensors in the room.
• The I-Star Circadian System mobile app, available for IoS and Android devices, is used to commission the system, as well as to adjust the programming after installation.

Sunlight, UVB and Vitamin D – Human Centric Lighting Beyond Melanopic Stimulation

by Ir. Rémy C. Broersma and Dr. Ir. Marcel P. Lucassen, Scientists at Signify Research Eindhoven UVB radiation initiates vital processes in our body, one of which is the production of vitamin D in the skin. It is well known that over-exposure to the sun may bring a risk. Less well known is that the same is true for insufficient sun exposure due to our indoor lifestyle. In Part 1 of this article, we first describe the scientific understanding behind vitamin D. In Part 2 we describe how artificial light can be enriched with a safe, low dose of UVB, to supplement natural vitamin D production in the skin. Not too much, not too little.

Light in the Service of Health – Bringing the Science of Light and Health into Everyday Life through Evidence-based Communication

Light does far more than let us see. In this episode of the LED professional podcast, Manuel Spitschan and Laura Kervezee, co-chairs of the Light for Public Health Initiative, explain how light acts as the master regulator of the body’s internal clock: it synchronises our physiology with the day outside, shapes mood and alertness, and times the release of melatonin, the hormone that governs sleep. The science is settled enough to act on, so the initiative has distilled it into 26 consensus statements on how light affects the body and well-being, written as practical, evidence-based guidance for individuals, employers, schools and cities. A compact 14-minute briefing on why good light is a public-health question, and what to do about it. Based on the authors’ article in LED professional Review #112.

deLIGHTed Talks #8: Good Light – Good Sleep

Full recording of deLIGHTed Talks #8, held online by LpS DIGITAL on 24 April 2025 (91 minutes). Dr. Renske Lok (Stanford University) shows that bright light during the day deepens nighttime sleep, reduces nighttime awakenings, improves sleep efficiency and lowers next-day sleep inertia. Dr. Jeffrey Hubbard (University of Lausanne / EPFL) compares how light and darkness drive sleep and wakefulness in nocturnal mice and day-active Sudanian grass rats. Chronobiologist Dr. Virginie Gabel, founder of Clock&Me, moderates the session and the discussion on what the findings mean for lighting design.
