點解酒店走廊D燈會咁暗？？

The lights in the hallway (as well as inside the rooms) are set dim intentionally for safety reasons.

In case of a fire, the smoke will spread around the hotel through its ventilation system and block the visibility.

By dimming the lights in the hallway, your vision will be prepared for a darker environment. As the smoke is lighter than air, which will flow at the top of the hallway. You will be able to find your escape routes at the bottom of the hallway.

It is in fact the same theory why during takeoff and landing, all lights in the airplane cabin are off.

因為間酒店要慳電費,所以特登用d無咁光既燈

可能走廊又唔會成日有人行，要咁光會好晒電，所以就咁暗光

應該是營造氣氛，也可能是你到的那間酒店沒有電，或是為了環保
