Aviation design company JPA Design has unveiled its “Afterglow” private jet biodynamic lighting retrofit concept that focuses on prioritizing passenger wellness, according to the company. The concept, which was shortlisted for the 2025 International Yacht &amp; Aviation Awards, combines high-end design with health-focused features.
Afterglow’s biodynamic lighting system, housed in a wall-mounted orb, appears to be a pretty but unobtrusive lighting option of the usual sophistication. However, it adjusts to the natural circadian rhythms of passengers, mimicking sunrise and sunset based on flight time and destination time zone. This thoughtful design helps mitigate the effects of jet lag by synchronizing with passengers’ physiological needs during flight.
In addition to the lighting system, the Afterglow cabin concept includes a range of features aimed at comfort and privacy such as a roomy combination bathroom and changing room, and a convertible sofa-to-double bed. Luxury amenities include a custom minibar, full-length wardrobe, and side furnishings. JPA Design emphasizes that this retrofit is a step toward sustainability, extending the life of aging aircraft interiors.

“True luxury today isn’t just about aesthetic beauty—it’s about creating environments that actively enhance our passengers’ wellbeing,” said JPA Design creative director Elliott Koehler. “Every design decision, from our lighting system to the intuitive cabin layout, serves both form and function.”
Although designed for the private aviation sector, the circadian concept of Afterglow could have broader implications for commercial aviation in the future.
