When illuminating a room the common theme is to light it from the ceiling down. Overhead lights are used everywhere, but there is a different option you could consider.
Low level lights are simply lights that are placed low to the ground. Lights are placed in this position to illuminate the floor primarily, with excess light travelling upwards along walls and the rest of the room.
An illuminated floor can give a unique effect to the atmosphere of a room. At night a simple corridor can be transformed into a unique glowing pathway with the use of low level lighting.
Low level lighting can be especially effective in business venues that see a lot of customers at night time. It can be used to help guide people in certain directions. A strip of floor lights for example can be a great way to direct restaurant goers towards the toilets.
