Healthe® New SunTrac™ A19 Seamlessly Transitions Between GoodDay® and GoodNight® Spectrums

Healthe® is excited to announce the launch of SunTrac™ A19, a product that combines engineered spectrums that have been optimized for both daytime and nighttime use into a single, dynamic, circadian lamp. Based on market demand, Healthe combined its proprietary GoodDay® and Goodnight® spectrums,…

The SunTrac A19's three presets – GoodDay, Afternoon and GoodNight – mimic sunlight throughout the day, enhancing the wake-sleep cycle for improved health and well-being. Alternatively, users can take advantage of customizable settings to create the circadian cycle that is best for them and their daily schedule. Like the entire SunTrac line, the SunTrac A19 is designed to work seamlessly with a variety of control mechanisms, enabling consumers to enjoy the right light at the right time.

The SunTrac A19 can replace any E26, Edison-based bulb that is commonly used in standard lamps and fixtures.

"The unique benefit of this new product is that it can easily be tailored to the time of sunrise and sunset at each user's location," said Holly Prievo, Product Manager for the SunTrac A19. "Currently, dynamic lighting products can be complicated to use. Our A19 lamp provides users the choice of unmatched simplicity or virtually unlimited flexibility, depending on each user's individual preference. A user can easily sync all the lighting in their home to the cycle of the sun in a "set it and forget it" manner, letting our technology work for them 24-hours a day. Or a user can assert greater control on a room-to-room, fixture-to-fixture basis to reflect one's personalized schedule."

To enable spectral control capabilities, including spectral transitions and dimming, SunTrac A19 can be paired with the SunTrac Wireless Switch or SunTrac App, both of which can also be used with groups of other SunTrac products. Alternatively, the SunTrac A19 can be automatically synchronized with daylight cycle using the recently launched SunLync™, a GPS-enabled control device.

Healthe lighting products deliver circadian well-being for building occupants with their proprietary, engineered spectra. The GoodDay spectrum is blue-enriched at 480 nanometers (nm), the peak wavelength for the body's circadian sensitivity. GoodDay simulates the blue in natural sunlight, helps increase alertness and has the potential to improve productivity during the day. The GoodNight spectrum, which is blue-depleted at 480 nm, promotes the body's natural response to sunset and ultimately sleep.

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.
