Lux (lx)

is the unit for luminous intensity. It tells you the light amount that is directed on a certain area. The luminous intensity is used to describe how good the light amount is in a specific space. The gained value is in proportion with the luminous flux, the optical-quality of the light and the distance from the area that is been lit.

We give recommendations for the installation distances between lights in gap spaces, to help you with choosing the right light. The recommendations can be found on every light fixtures own webpage, under “General information”. The recommendations are based on both measurements and fitting lights in a test room. Please observe that when ageing the vision weakens and the need for light increases. In that case we recommend that the lights would be installed with smaller distances in between.

The table helps you to choose the right illuminance value for your home. In practice, there are of course many other factors that affects the need of illuminance as well. These can be e.g. age, sight and so forth.

Light figure

A light figure is available for almost every Limente Light fixture.


The following conclusions can be drawn from their values:

  • 100° tells you the light angel. The angel should be more than 90 degrees if you want a light in the gap space of the kitchen to reach the whole table area in the depth direction
  • 495 lx tells you the light efficiency 50 cm from the middle of the light to the light source (the distance match the regular gap space in the kitchen. 300-500 lx is considered a good value) 123 lx tells you the light efficiency 1 m from the middle of the light to the light source
  • Ø 0, 97 m tells you the area in which the light efficiency is at least half of the middle of the light (495 lx). Correspondingly Ø 1, 98 m tells you the area in which the light efficiency is at least half of the middle of the light (123 lx)
