HOW MANY LUMENS DOES A LIGHT BULB NEED?
The most correct calculation is to multiply the lux
that we need by the square meters where the light is scattered. For example:
·
If we want 80 lux in any point of a
·
If we want 300 lux on a 2m2
livingroom table, we will use a 600 lumen light on the table.
It is important to take into account that we will not find light bulbs
of a random number of lumens, and therefore we will need to take the quantity
that most approaches the one that we need.
This calculation is approximate because it does not take the third
dimension into account. If the light bulb is near us we will need less lumens
in order to obtain the same number of lux, and if the
ceiling is high we will need more... or we could also hang the lamp down.
