mounting height may lead to lighting hotspots and require mounting in a different orientation (e.g. columns).’
• Use shielded fixtures that emit light downward, to reduce light intrusion and sky- glow while maximising light on the ground.
• Think about surfaces and the level of light that they will reflect. If lighting is purely for aesthetic purposes – such as architectural accent lighting – more reflective surfaces may need less intense light to fit the purpose.
• Consider Lighting Controls that activate only when the light is needed, such as photocells, microwave sensors and passive infrared sensors to monitor absence, presence, motion and light levels. These are particularly useful for lighting low traffic areas such as walkways, entry-ways and loading bays.
• Choose the right level of illumination for the area’s purpose. A loading bay, for instance, will need more illumination than a pedestrian walkway between two buildings. Think about what light is actually needed for safety, security and functionality in each individual space, as opposed to aiming for full illumination everywhere.
• Consider the impact of colour temperature. Choose the colour temperatures that are appropriate for the environment you are trying to illuminate – LG06 gives good reference to the use of different colour temperatures in exterior applications.
• Use low energy lighting A wide range of LEDs are now available to fulfil every commercial outdoor lighting requirement – from functional floodlights and security lights, to decorative uplighters and sconces.
• Employ competent lighting designers who will provide the right light, in the right place, at the right time (in line with ILP guidance).
With good lighting design and the right
products, it is possible to create outdoor commercial lighting that fulfils the client’s needs and protects surrounding areas from
unnecessary light pollution. Red Arrow can support with both, with our new state-of-the art facility providing electricians with the latest energy saving lighting products and design services. Visit
