    Better light,

    less power

    Energy Efficiency  

    Cutting-edge white light sources like MASTER CosmoWhite help cities grow. Not only are they more energy-efficient than conventional alternatives, but their clean white light is perceived as being brighter than it actually is. This means you can please the public while reducing light output by as much as 30%, saving municipal funds.

    Can white help you go green?

    White light gives you a multitude of new ways to save energy and help the environment. The higher perceived brightness of white light means you can increase the pole distance between luminaires in new installations. In addition, you can reduce the installation height during refurbishments using lower wattage lamps, or install lower wattage lamps in upgrades.


    Even without taking advantage of these opportunities, Philips super-efficient lamps will improve your sustainability through reduced energy usage and lowered C02 emissions.

    Less can be more

    White light makes it feasible to actually reduce light output, because it is perceived as being brighter than it actually is. This advantage has already been recognized 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 color rendering of 60 or more, which is the case with white light.

    How perceived brightness works?

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

    Comparing energy consumption  

    Get ready to save power. Just by upgrading a lighting installation with new light sources, you can reduce energy consumption by as much as 43%. With a completely new installation the savings rise to 56%, and with energy-efficient LED technology even greater savings are possible.


    High quality white light is therefore the ‘green switch’ solution for outdoor installations. It reduces CO2 emissions to a level that was previously considered impossible, and cuts energy bills significantly.
