White light is the ‘green switch’ solution that allows you to make significant savings in a number of ways. For example, it’s possible to specify a greater distance between luminaires in new installations, reduce the mounting height during refurbishment, or install lower wattage lamps in upgrades. So you can benefit from reduced running costs and lower CO₂ emissions as well as superior light quality.

With its proven higher perceived brightness, white light makes it feasible to actually reduce light output. This advantage has already been recognised in British lighting standards. In the UK, the level of illumination required by law on subsidiary roads and paths may be reduced by as much as 30% when the light source has a colour rendering of 60 or more, which is the case with white light.

When lighting levels are low, the rods in the eye’s retina become more active. They pick up light sources with higher levels of blue light emissions more readily. The light source is not necessarily giving out more light overall, but it is giving out high levels of a frequency of light that can be picked up by our eye. This is what white light does and why it has a higher perceived brightness.

Even by just upgrading a lighting installation it is possible to reduce energy consumption by as much as 43%.  With a new installation the savings rise to 56% and using high efficient LED technology makes even greater saving possible. High quality white light is therefore the ‘green switch’ solution for outdoor installations, reducing CO₂ emissions to a level that was previously considered impossible, while simultaneously cutting energy bills by a significant amount.
