White light
It has long been known that the eye responds better to white light than to more monochromatic sources and it is for this reason that white light schemes are growing in popularity.
An important factor is that better lit environments are likely to reduce the volume of crime and to eliminate, to some extent, the opportunities for crime. So, the introduction of new, and increasing output white light sources is making a real contribution to this issue.
WRTL's ranges of functional and urban lanterns are purposely designed to accept the new white light sources and prime examples of this are the Newcastle/North Tyneside PFI and the Staffordshire PFI where white light is a key requirement.
