How to calculate the amount of light appropriate for a room

The Right Amount of Light for each room

To calculate the right amount of light for each room, the first thing that must be taken into account is the activity that will be developed in it. The standard recommendation is 4W Led light for each square meter. Therefore, a room of 30 m², which would be a more or less large room, would need 120 W of light that should be divided into different points according to the distribution of the room.

This is the simplest calculation possible to calculate how to light a room, but if you want to do a much more professional study you will have to know concepts such as lumens and lux. The lumen is the way to measure the intensity of the light of a lamp. Led bulbs and lamps always indicate how many lumens are, so it is easy to know and no calculation is necessary.

However, when we talk about lux the thing can get a little more complicated. Lux refers to the way in which the human eye perceives that light. It is based on the lumen and the most mathematical way to explain it is that a lux equals one lumen per square meter. And this is how the calculation of the amount of light needed by each room is made.

The most appropriate amount of light for a living room

The general lighting of a living room is estimated to be around 300 lux. Therefore, a living room often square meters would need 3,000 lumens to be properly lit.

In the case of a dining room, the light intensity can be a little lower, 200 lux, so for a dining room of the same size we would need 2,000 lumens. It is easy to make the calculation of what bulbs we have to buy knowing how many lumens each bulb has (information always present on the package) and how many of them we have in each room.

We must always bear in mind that we are talking about standard values ​​and that, therefore, they will depend a lot on the tastes of the people who live in the house. Of these tastes will also depend on the choice of natural light or warm light for these two places in the house.

The most appropriate amount of light for a bedroom

An adult bedroom should be around 300 lux, while one of the children can go up to 500 lux since it is assumed that the children need more lighting in their rooms. While adults only use the bedroom to rest at night, in the case of children is their playground.

In the adult dormitories that are also used as a workspace due to the lack of an office in the home, the amount of lighting will have to be 500 lux too, as in the case of children, this without counting on having that there is a point of direct and intense light on the work table so that the tasks can be carried out without problems.

The most appropriate amount of light for the kitchen and the bathroom

Although experts recommend an intensity of 300 lux, many people want to have lots of light in these rooms to work comfortably. An intense light in the kitchen facilitates tasks such as reading a label of a product or being able to perform some cooking tasks.

In the bathroom, intense light can be very suitable for makeup or for own activities of the bathroom, such as shaving or shaving. That is why many people opt for 500 lux lighting in these rooms. Since the consumption of LED lamps and LED Light Bulbs is not high, getting a higher intensity does not mean a large increase in consumption and therefore when in doubt, you can opt for 500 lowering the next time if it is considered excessive.

The most appropriate amount of light for an office

It is estimated that 500 lux should be used for an office. But if the office is a place where precision work is carried out that needs a lot of lighting, it would have to go up to 800 lux. It is the case of workshops or sewing rooms, which require a high intensity of the light to carry out the work.

This is the maximum intensity that will be needed in a home and is limited to this type of activities, since usually, 500 lux is a sufficient intensity for any of the activities that take place in any room of the house.
