Which lumen for which room?
Here you can see a table with the Luxuries that we recommend for each stay . Keep in mind that this is approximate values , that's why several values are given for each stay. This is because each person wants a type of light based on their personal tastes.
| Living room lighting: | 100 – 300 Lux |
| Dining table lamp: | 350 – 500 Lux* |
| Room light: | 100 – 250 Lux |
| Kitchen lighting: | 200 – 300 Lux |
| Bathroom lighting: | 150 – 250 Lux |
| Hallway lighting: | 100 – 200 Lux |
| Bathroom mirror lighting: | 400 – 500 Lux* |
| Study or reading table: | 400 – 600 Lux* |
* For the dining table, bathroom mirrors and study tables, this is only the area of the table and the area near the mirror. This is not the amount of light for the whole room, it is only the light for a very specific area, which can be 1 m² or less.
Practical examples to calculate the light you need
1) To calculate the light in rooms, simply use the lux formula . If we have a room of 18 square meters, in the table you see that it must have a minimum of 100 lux and a maximum of 300 lux. Let's imagine that you want something in the middle and you choose 200 Lux.
Lumens = 200 Luxes x 18 m² ——> Lumens = 3,600 lm.
Now, with this information about the lumens you need, you can choose a lamp of around 3,600 lumens. If there is less, at least the light is well distributed and if there is more, it can be focused or adjustable.
2) We will calculate the light needed in an area of a room such as a dining table . We have a dining table 2 meters long and 1 meter wide. The normal thing would be to use 2m² in the formula.
But we recommend adding a little more surface area in very specific areas , because normally you will want to have light on the chairs and the area near the table, we will therefore estimate 3 m². In the table you have the measurement of 300 to 500 Luxes for dining tables. You want a lot of light intensity to eat with good lighting so you choose 500 Luxes as a reference.
Lumens = 500 Luxes x 3 m² ——> Lumens = 1,500 lm.
You will only have to choose a lamp that provides about 1,500 Lumens and, possibly, the shape of the table. If the table is rectangular or large, it is better to place ceiling strips or several lamps. On the other hand, if the table is square or circular, you can use lamps with a circular lampshade.
