For example, in an adult's bedroom, you need lighting to be lower to wind down your body for sleep. This means that lighting is utilised in the interior design process to bring out varying tones across space. Lux measurements are roughly 10 times a foot-candle measurement, as a foot-candle is 1 lumen per square foot, and a lux is 1 lumen per square meter.

As a way to measure the actual performance of a scheme, Leni was brought in during April 2014.

Sufficient emergency lighting should be provided in the event of the failure of artificial lighting (this should be independently powered from the main light source).

Glare can have two effects: it can impair vision, in which case it is called disability glare, and it can cause discomfort, in which case it is called discomfort glare.
