Hotel is a typical hospitality application that always desires the guests to immerse themselves in a comfortable space. Guests spend most of their time in the hotel for relaxation and sleep thus the lighting design requires:

• In general lighting mode, the CRI should be > 95;
• The light should be dimmable and tunable to a very warm color temperature for a progressive scene transition from relaxed to sleep and does not affect the natural secretion of melatonin.

This project applied Yuji Lighting Cira-Flow Option 2 strip, tuning/dimming the color temperature from Coziness mode (3000K with 98 CRI_ to Night-light mode (1250K), achieving an m-DER of only 0.042 and enlarging the illuminance area with safe circadian stimulus.
