Question 1

At what height should wall lights be installed?

Accepted Answer

In living rooms, hallways and entrance halls, they are usually installed between 150 and 180 cm from the floor. This height allows the light to be distributed comfortably and prevents the luminaire from being directly at eye level. In bedrooms, if they are placed next to the headboard, the height can be adjusted to the real reading use. As a reference, they should sit slightly above shoulder height when the person is sitting in bed, allowing the light to be directed towards the book or support area.

Question 2

How many lumens should a wall light have?

Accepted Answer

For ambient lighting, between 300 and 700 lumens per wall light is usually enough. For reading, bathrooms or more specific tasks, it is advisable to work between 500 and 1000 lumens, depending on the distance to the illuminated plane and the type of shade. Outdoors, the amount of light will depend on the area. An entrance can work well with 600–1200 lumens, while a decorative terrace may require less if atmosphere is the aim. The important thing is to avoid excessively frontal light that causes glare.

Question 3

What colour temperature is best for wall lights?

Accepted Answer

For living rooms, bedrooms and relaxation areas, 2700K or 3000K is most commonly used, as these temperatures create warm and comfortable light. In bathrooms, kitchens, functional hallways or work areas, 4000K provides more neutral and precise light. In residential outdoor areas, 3000K is usually a balanced option because it provides good visibility without creating an overly cold effect. In technical or security areas, 4000K can be used if greater clarity is desired.

Question 4

What IP rating does an outdoor wall light need?

Accepted Answer

For covered outdoor areas, such as porches or protected terraces, IP44 may be sufficient if there is no direct exposure to heavy rain. On façades, in gardens, at entrances or in more exposed areas, it is advisable to choose IP54, IP65 or higher. In bathrooms, the IP rating should also be assessed according to the installation zone. Near the shower or bathtub, higher protection levels are required than on a wall away from water. In addition, the electrical safety zones indicated by regulations should always be respected.

Question 5

Is a wall light with integrated LED or replaceable bulb better?

Accepted Answer

A wall light with integrated LED usually offers a more compact design, better optical control and greater efficiency. It is a good option when looking for a slim, modern luminaire or one with a very specific shape. A model with a replaceable bulb offers more flexibility, as it allows the output, colour temperature or type of bulb to be changed easily. It can also be more practical in decorative designs where the bulb forms part of the aesthetic.

Question 6

Can wall lights be used as the only lighting in a room?

Accepted Answer

Yes, but it must be planned correctly. In small rooms, hallways, bedrooms or ambient areas, several well-distributed wall lights can function as the main lighting. However, in kitchens, bathrooms or large living rooms, it is usually advisable to combine them with general lighting or support points. The key is to calculate the total flux needed and avoid all the light coming from a single direction. A room lit only from the walls can feel very pleasant, but it needs a balanced distribution so as not to create excessive shadows.

Question 7

What type of wall light should be chosen for a decorative wall?

Accepted Answer

To highlight a wall, indirect-light wall lights, double-emission models or designs that project defined beams upwards and downwards work very well. Models with decorative materials can also be used if the luminaire is intended to have visual prominence. If the wall has texture, stone, brick or cladding, grazing light can enhance the relief. On plain walls, geometric or plaster designs help create a more architectural and discreet effect.
