How to Choose a Bulb (Part 2)

This post is a continuation from Part 1 on How to Choose a Bulb. Lately, we have gone through The different characteristics of a light bulb: power, lifetime, colour temperature, and colour rendering index.

We will now cover the criteria for choosing a light bulb.

Selecting a light bulb means selecting it according to:
its usage;
– the
place where it will be used;
– the load;
– the lighting system that will receive it;
– and the desired characteristics,
as we will see below.

Several points are to be taken into consideration when choosing a bulb:

Criteria for choosing a light bulb

You have the choice between:
– incandescent bulb;
– low-energy bulb;
– halogen bulb;
– LED light bulb;
– halogen bulb;
neon.

The packaging of the bulb tells you its energy class, luminous flux, power and lifetime.
– Don’t forget to check that the maximum power of the bulb can be supported by the support (lamp or lampshade), otherwise serious damage may occur.
– Study in a second step: the colour temperature and the colour rendering index, these parameters also qualify the quality of the light.
The choice of the bulb will impact your electricity bill and the environment.
– By choosing low-energy light bulbs, you can make significant savings for a small investment.

Its aestheticism

Because of the multiplicity of shapes and colours, aesthetics is also important.
– These will be able to colour the light, to opacify it, to give it a look…

The following comparative table brings together all the characteristics listed for each type of bulb:
