How to get the ideal LED lighting for every room of my house?

Posté le sept. 5, 2019 | Catégories: News, Lightning & Decoration

Since the explosion of LED lighting in our homes, and the gradual disappearance of old incandescent bulbs, it became difficult to judge what light intensity is ideal for each room in the house. It is true that each room in the house requires specific lighting. For example, it is important to have significantly better lighting in a bathroom or kitchen than in the living room or bedroom.
The right lighting depends on several parameters: the type of room, the desired ambiance, and also the size of the area that needs to be illuminated.

If you are lost between all the options, follow our advice and become a true specialist in LED lighting!

How to get the ideal LED lighting for every room of my house?

1. Watts/Lumens : how to make the difference

2. Kelvin degrees: what does it mean ?

3. Lux: another parameter to consider

4. Number of Lumens per room: a few numbers

1. Watts / Lumens: how to make the difference:

Watts (W): This unit of measurement calculates the power consumption produced by the light source. In the case of LED bulbs or LED spots, this unit is not relevant since it does not reveal the light intensity produced. This unit in Watts only allows you to evaluate your energy consumption.

Lumens (Lm): This unit allows you to truly evaluate the light intensity of your LED lighting. This is the luminous flux produced by your LED bulb or your LED spotlight. This is the real criterion to remember when choosing your bulb. Indeed, a bulb that consumes a lot of watts, does not necessarily diffuse a lot of lumens, and vice versa.

2. Kelvin degrees: what does this mean?

Another important point to consider when you want to light your house with LEDs: the color temperature. This data is calculated in Kelvin degrees (° K)
This wasn't a problem when incandescent bulbs were used since only one color of light was produced.

The LED bulbs found on the market today vary between 2700 and 6500°K. The higher the value in Kelvin, the colder the color of the light will be. Here are some indications:

Very warm white : orange-like (fire flame like) : about 1500°K
Warm white : orange-yellow like, about 2700-3000°K
Natural white : neutral white daylight, about 4000°K
Cool white : pure blue-white color, about 6000-6500°K

3. Lux: another parameter to consider

This more mathematical approach in terms of domestic LED lighting can also be considered. This data serves as a basis of calculation to determine the amount of lighting needed in a room. These are the Lux (Lx). The Lux measure the efficiency of a lighting, or the flow of light received by a surface. It is calculated using the following formula: lux = lumens / m² or lumens = lux x m².

Here is an estimation of the value of lux required according to the rooms of the house:

Corridors, staircases...: 100 lux
Bedroom, living room, dining room, office: 100-150 lux
Kitchen, bathroom, playroom: 200-250 lux
Garage, workshops: 350-500 lux

For example: a 15m² kitchen requires about 200 lux. The number of lumens required is therefore calculated as follows: 15 m² x 200 lux = 3000 lumens.

A GU10 LED bulb is about 500 lumens nowadays, so you will need 6 bulbs for a proper lighting in your kitchen.

4. Number of lumens per room: a few numbers

The estimates given below will have to be finely-shaded according to the litted areas, the atmosphere you want to bring to each room and to your home in general, and your personal preferences as well. But it can still give you an idea:

Living / dining room (30m²): 9000 lumens
Kitchen (15m²): 3000 lumens
Bathroom (10m²): 3000 lumens
Bedroom (15m²): 2000 lumens
Office (15m²): 4000 lumens

Congratulations! You now have all the keys to bring optimal LED lighting to your home and make your interior pleasant and warm while always saving more!
