With the ability to largely affect the mood of a room, lighting is the most important element to consider when designing a space. In addition to altering the mood of the occupants in a room, lighting can transform the room in shape and size. Lighting dictates what space “feels” like. Bright white lights glaring off walls create a clinical atmosphere. Light can create a warm, engaging atmosphere that enhances moods, alters behaviour and affects emotions. Warm white lights make any space a little more welcoming. Bright light intensifies emotions, regardless of whether they are negative or positive. Low light keeps our emotions steady, which means that people tend to make better decisions in lower light, and find it easier to agree and compromise when negotiating. Anything that can alter our emotions and control our behaviour is important. Appropriate lighting, without glare or shadows, can reduce eye fatigue and headaches; it can prevent workplace incidents by increasing the visibility of moving machinery and other safety hazards.
