Why use photocells?
Photocells are an economical way of switching lights on and off using dusk & dawn as the trigger. In our vast range from Royce Thompson and Lucy Zodion we have a photocell to suit almost every applivcation. They provide an efficient service, lights on when necessary and off when not rquired saving the the user energy & money.
Standard photocells come at dusk and switch off at dawn. Some of the reasons for having the lights on all through the night may include meeting health and safety requirements or for securty purposes. For users that do not require the lights to be on all night may want to consider a 'smart' part night photocell, this style of photocell will switch on at dusk and then tun off at midnight, if required it will switch back on at 5am. The most popular part night unit is the Zodion SS9.
Our range of Royce Thompson and Lucy Zodion photocells are available in a number of configurations, with light level detection or Part Night operation, to meet the various needs of the street and amenity lighting market, including:
One Part NEMA photocell - the photo-electronic control is housed in a polycarbonate casing with a UV stabilised plastic cone, with base fixing to a NEMA socket as standard, or with optional flying leads.
One Part miniature photocell - including a standard miniature casing, ideal for use where installation space is limited or minimum aesthetic impact is specified.
Two Part remote photocell - enables placement of the lens to monitor light levels, whilst the controller is placed within reach in the lighting unit to permit functional testing.
Two Part miniature photocell - allows both remote placement of the lens, and installation of the miniature controller in lamps where space is limited.
Generally, selection of the most appropriate photocell for the installation is determined by the performance, energy savings and value for money required from the photocell.
