Horticutral Lighting
It is often to see various lighting fixtures mounted on the wall of buildings to provide illumination. This type of light is called ‘wall pack light’ in general. Wall pack lights refers to the lighting fixtures that are attached to a exterior wall of buildings or a vertical surface. There are multiple applications for wall pack light, such as walkways, entry and exit, building perimeter, parking doorways, etc. Most of wall pack lights are used for outdoor applications. Therefore, wall pack lights must be able to withstand harsh environments. We all know the basic requirements of wall pack lights includes the abilities to against water, corrosion, extreme high or low temperature, and sun light. However, wall pack lights which meet the basic requirements solely is far from effective operation. There are 5 tips to help you use wall pack light more effectively.
Install only where it must be
The key point of illumination is to use minimal lighting fixtures to achieve appropriate illuminations and comfortable lighting experience. Wall pack lights are aimed at providing higher visibility for pedestrian as well as maintaining security around the buildings. Places that have no pedestrian activity or are not related with security issues, are no need to be installed with wall pack lights. Otherwise, it will be just a waste of time and energy. It may cause lighting pollution even worst. Pay more attention to the places that need illumination necessarily, such as walkway, entry, and exit. Distance of wall pack lights is also critical. If the fixtures are to close with each other, lighting will be partly or fully coincided. Appropriate installation distance contributes to uniform and efficient lighting.
CCT optional - enjoy different atmospheres
Wall pack lights not only provide illumination but also decorate the buildings. Light sources with different color temperatures offer multiple visual effects and different atmospheres. Unlike conventional light sources, advance technology allows LEDs to bring a range of correlated color temperature according to the needs of users. In simple terms, what we called ‘warm white’ or ‘cool white’ refers to Correlated Color Temperature (CCT). The CCT of warm light is about 2700K to 3000K and the cool white light is higher than 5000K. White light makes pedestrian more concentrate on their way, while warm white light let them feel relaxed and release the stress. Wall pack lights with optional CCT are more effective compared to the single color one.
Glare shield - protect pedestrian and environment
Glare refers to the visual conditions that cause visual discomfort and reduce the visibility due to unsuitable brightness distribution of lighting fixtures or extreme brightness contrast in space or time. Long-term exposure to glare can cause visual fatigue. In addition, the glare is very annoying as it often causes people to feel anxiety, lack of concentration and other psychological discomfort. It would cause serious insomnia and headaches even worse. Unsuitable distribution like uplight will also trespass the sky. Therefore, glare shield is important to protect pedestrian and environment. Wall pack lights are suitable for use in a wide range of environmental zones where control of nuisance glare is critical. Wall pack lights come with a diffuser optic design are able to delivery non-dazzling lighting distribution, approaching maximize spacing between fixtures whilst minimizing light pollution.
Controls - save energy and cut electricity bill
The most effective way of using wall pack light is operated with applicable controls and light levels. When selecting controls, consider the specific needs of applications. Applications such as entrance, walkway, and exit with limited or sporadic activity should be applied with controls to save energy and cut electricity bill. Areas with security issues or as the demarcation of the building perimeter can achieve greatly energy saving by using intelligent control. But the type of control should be carefully considered. Take photosensors into account as they are capable of controlling various fixtures with similar control needs on and off automatically based on ambient light levels. Applications that are not related with entrance or walkway are more suitable to install with occupancy sensor. Lighting fixtures are turned on automatically when occupancy sensors are triggered and turned off within several minutes after all occupants leaving the detecting area. Adding controls is a more effective way to use wall pack light due to the reduction of energy consumption and electricity bill.
Emergency battery backup - keep safety
As mentioned, wall pack lights are used for maintaining security. When power supply suddenly off or something wrong with lighting fixture, perimeter of the buildings will be plunged into darkness. Accident are of high possibility to present as the lack of visibility. To prevent danger caused by power outage, wall pack light should equipped with emergency battery. Wall pack light with built-in battery can provide backup power for several hours, offering clear vision and safer environment for pedestrian. Though emergency battery cannot lasting for a long period, it still provide precious short term illumination for pedestrian to take further actions, avoiding disorder traffic as well.
