Haarlem is a city on the outskirts of Amsterdam, which retains its medieval air with cobbled streets and gabled houses. That is why the characteristic luminaries of the district have been updated to an LED version. Internally, the luminaries include an LED unit (mld unit), lenses, controller, and heat dissipater. The interior is adapted for Spaarne accessories and, therefore, can be assembled quickly and easily in pre-existing locations. This has provided the local council with a good LED solution for its characteristic street lighting. A 2700K (extra warm white) temperature colour was chosen. This clear colour is well matched to the lamp post and the area where the lighting is installed.
