• To avoid wasting electricity on lighting, natural light must be used to the fullest by choosing curtains that are as transparent as possible so that you do not have to switch on light bulbs during daylight hours.
• Inspired by the Danish lifestyle hygge (hyoo-guh), which describes a feeling of cosiness, warmth and comfort at home, we recommend using several luminaires with warm light (1800–2700 K) that is reminiscent of a sunset or the glow of a cosy campfire.
• The further the luminaire is from the floor or table top, the more the light emitted by the bulb is dispersed; therefore, rooms with high ceilings need a light source with higher luminous flux, or more lumens (lm).
• Wall lamps, floor lamps or desk lamps are recommended for reading, doing crafts, studying and working on the computer.
• White colour LED lighting (3200–4000 K) is more suitable for productivity and performance in work areas.
