Bright Light Therapy for Depressed Geriatric Inpatients

the Verilux® HappyLight® Lumi Plus light therapy box, which delivers UV-free, full-spectrum LED light at an intensity of 10,000 lux

The control group will use the same light box device, configured to emit dim red light. This will be achieved by setting the box to its lowest brightness setting and overlaying a translucent red filter over the light display. This setup is intended to maintain the appearance and experience of light exposure while minimizing any therapeutic effect.
