Objective:
We designed and implemented a novel neonatal intensive care (NICU) lighting system to support the current understanding of daylight-coupled physiology.
Methods:
We created a system that generates wavelengths corresponding to the known blue and violet activation spectra of non-visual opsins. These are known to mediate energy management and related physiologic activity.
Results:
Light produced by the system spans the visible spectrum, including violet wavelengths that are blocked by modern glazing and not emitted by standard LED fixtures. System features include automated light and dark phases that mimic dawn/dusk. The system also matches length of day seasonality. Spectral composition can be varied to support translational research protocols. Implementation required a comprehensive strategy to inform bedside providers about the value and use of the lighting system.
Conclusion:
Full-spectrum lighting for the NICU is feasible and will inform the optimization of the NICU environment of care to support optimal neonatal growth and development.
