Time to consider outdoor lighting
03 October 2017
Ecolighting believes security lighting is one of the most useful steps businesses can take against intruders, but warns companies that they should make sure such lighting doesn’t undermine the effectiveness of CCTV systems; a bright glare from a badly located security light might well impact on a camera’s ability to record a clear image.
Ecolighting’s Tom Tierney says: “Exterior lighting is often scrimped on because of the energy costs and maintenance regime involved. Normally floodlighting is mounted up high on posts or walls to prevent interference and maximise light distribution, but this creates issues with lamp replacement, cleaning and repair.
“Most of these issues can be avoided with new LED floodlighting. Good quality floodlighting will pay for itself in light output and reliability in the long term.”
Tierney adds that, to minimise energy consumption, security lighting should be controlled by sensors: “There are two types of sensor typically used in outdoor security lights - a PIR sensor and photocell. The PIR sensor is essentially a motion sensor and so movement within a given range will trigger the light for a short, often adjustable time. Alternatively, a photocell measures ambient light levels and triggers light on and off at dusk and dawn.”
When it comes to the wellbeing of staff and visitors to your site now that the dark evenings are with us, it is important that all areas are lit at approximately the same level. Light that is not uniform creates shadows that can render steps, curbs, or even fallen branches from a nearby tree, serious safety hazards.
“To avoid slips and trips or more serious mishaps, it is essential that outdoor spaces are clearly illuminated,” continues Tierney. “To this end, it is recommended that you pay special attention to the lighting around the building’s perimeter; entrances used by vehicles and/or pedestrians; any on-site roadways; open yards and car parks; and, of course, loading docks. Usually bulkhead style lighting is used to add extra illumination to these key areas.”
“And, of course, throughout the year, make regular checks to ensure that all outdoor light fittings are in perfect working order.”
