Frequently Asked Questions (FAQ)
WHAT TYPE OF LIGHTING 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 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.
WHAT IS THE DIFFERENCE BETWEEN 306, 316, A2 and A4 GRADES OF STAINLESS STEEL?
The most common type of Stainless Steel is 300 Grade. Approx 70% of Stainless Steel Products fit within this grade. The 304 Grade contains a higher content of Molybdenum, Nickel and Nitrogen, making it more resistant to corrosion and stress. This Grade is also known as A2 Stainless Steel. The 316 Grade, also known as A4 Stainless Steel takes this further and is the best material for some corrosive atmospheres such as salt water.
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.
WHAT TYPE OF LIGHT ARE BUGS ATTRACTED TO ?
This arises mainly in the Food and Drugs sectors but the same principals apply to exterior lighting. Light in the 330-350 nm wavelength seems to be most effective in attracting houseflies, one of the primary target pests. By checking the published data of the lamp you intend to use, you can decide if the lamp is suitable. Further details on request.
Is an Energy Label required for Lighting Products ?
