Frequently Asked Questions


WHAT TYPE OF POLE DO I NEED?  Generally the pole must be suitable for the size & weight of the luminaire and any brackets etc. Also consider other issues such as: A). How Luminaire/brackets will mount, B). Local wind speeds, C). Local soil conditions for mounting, D). Architectural appearance, RAL, etc, E). Location of control gear, fuse, etc, F). If local authority standards apply, G). If planning permission is needed. See also seperate leaflet on “Installation of Poles”.

WHEN SHOULD I USE AN OCCUPANCY SENSOR ? In all applications where luminaires are not required to be switched on constantly, a sensor control should be considered. Generally, only LED lights are suitable to be controlled by occupancy sensor. These lamp types can be either switched off or dimmed down when an area is vacant.

WHERE SHOULD LUMINAIRES WITH PHOTOCELLS BE LOCATED ? Ensure Luminaires equipped with a Photocell are not installed in areas where they may be switched off by local lighting including car headlights, other lighting in the vicinity, etc. Consideration should be given as to whether an internal photocell or a remote photocell should be used.

INTERNAL OR REMOTE PHOTOCELL ? Generally, use a remote photocell if possible. This is less costly and will require less maintenance. Also, it can be located for easier access to avoid false activations.
