The Lighting Industry’s €3 to €300 Opportunity

The lighting industry is making a costly error by competing on energy efficiency alone. The 3-30-300 rule from real estate puts a building’s yearly costs per square metre at about €3 for utilities, €30 for rent and €300 for the people working in it — yet lighting innovates almost entirely inside the €3 category. Good light that follows natural light and keeps the biological clock in sync improves alertness, concentration and cognitive performance, which is where the €300 is. This episode argues for selling value through human health and well-being instead of minimal savings.

This episode asserts that the lighting industry is making a costly error by focusing solely on energy efficiency rather than the vast potential of enhancing human output.

It introduces the 3-30-300 rule, a real estate metric showing that salaries and personnel costs (€300) far outweigh utilities (€3) — yet the industry primarily innovates within the minor energy category.

Good light, which mimics natural light to synchronise the biological clock, improves occupant alertness, concentration and cognitive performance. By shifting the emphasis from minimal savings to creating value through human health and well-being, the sector can move past price pressure and capitalise on the substantial €300 cost category.

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.
