    How many lights do I need?

      There is not a definitive answer for this as it depends on the type of room / area, the size of the room, the ceiling height and which product you're looking to install.


    In a typical 4m x 4m bedroom for example could be illuminated with 4x downlights, or a single centre downlight or bulb, lit with diffuse uplighting wall lights, or simply just with bedside lamps.


    It is very much a personal preference which way you go in residential applications, but in a commercial application where minimum lux levels are required you may need to perform a simple grid layout.
