Light is one of the most important elements of interior home decoration. Who can live without light? Without light, we would not be able to perceive colour, textures or patterns. And, more importantly, we could not see the space around us and the shapes, forms and lines. There are two types of light: natural and artificial.

1. Natural Light:

The source of this light is our beloved sun. The intelligent orientation of fenestration will maximize the effect of natural lighting in a room. Interior designers can then plan space and choose colours according to the amount of natural light it receives during the day.

2. Artificial Light:

Man-made lighting sets the mood and ambience for a living space. There are three types of artificial lighting: Task, Ambience and Accent. Let’s briefly explain each of them.

Task Light:

They have a purpose for a specific task, like desk lamps, under-mount cabinet lights, etc.

Ambience Lighting:

This takes care of the total lighting of a room in general.

Accent Lighting:

The purpose of accent lighting is to emphasize certain elements in the space. For instance, it could accent the textures of a wall or a beautiful art piece. It could even be used to create drama, rhythm and so on. It can usually create a specific mood and style in a space.

A savvy designer knows how much light a room would need and how to create the desired mood. The three lighting types should be included in any room to achieve a functional and effective lighting design. See the image above.

Now that you know how to differentiate the types of lighting, we can go deeper into the complexity of artificial lighting in interior home decoration.

For many, many years we have been buying bulb lights by using “watts” as a reference. The only thing we needed to know was if we wanted a 100, 60 or 25 watt bulb. In the lighting industry, there are certain terms that we need to learn in order to obtain the lighting that we really need for specific applications. These words are “lumens” and “kelvin”. But, let’s start with watts.

What Is a Watt?

Watt is a unit of electricity used by a device or light bulb. In reality, it has nothing to do with light itself.

What Is a Lumen?

A lumen is a unit of light output from a device or bulb. To put it in simple words, a watt is what you pay for(electricity) and a lumen is what you see (light).

What Is a Kelvin?

Kelvin is the colour temperature of the light bulb. The three primary types of colour temperature for light bulbs are:

  1. Soft White (2700K-3000K),
  2. Bright White/Cool White (3500K-4100K), and
  3. Daylight (5000K-6500K).

The higher the degree Kelvin, the whiter the colour temperature. Kelvin does not affect lumens at all.

Here you have some tips to use Kelvin more effectively in your interiors:

Soft White or Warm White:

Good for bedrooms and living rooms, since they give a traditional cozy feel to the room.

Bright White/Cool White:

Good for the garage, kitchen and bathrooms. It energizes and whitens the space.


Good for basements, garages, for makeup mirrors or application of makeup, drafting and intricate projects. It emphasizes contrast and true colours are perceived clearly.

There are a variety of household type light bulbs in the market. The LED bulb is the most efficient in energy usage (approx. 16 times less electricity than an incandescent bulb), with a life span that is over 16 times longer than an incandescent bulb and a higher emission of lumens.

Here are some of the most common conversions that you might need to know:

  • 60 W is 900 lumens,
  • 75 W is 1125 lumens, and
  • 100 W is 1500 lumens.

Look for a light bulb that is at least between 2700 and 3200 Kelvin to get a decent quality of light.
