Common areas of apartment complexes which have 24hr lighting, in car parks, corridors and stairwell, are potentially great areas where new lighting can save a lot of money. By reducing energy usage power bills are brought down, and green house causing emissions are reduced.
Good quality lights also require less maintenance, especially if the existing lights are starting to age. Greater efficiency can be achieve by the use of LED lights which provides the same light output with much less energy use. Additionally the use of individual motion sensors in each light reduces usage even more so. One type of motion sensor that is becoming more popular now days is High Frequency motion detection. They sense a change in the density of the volume within the detection area, and operate in a similar way weather radars work. But instead of detecting clouds, detect people. They respond quick than tradition IR sensors and can be incorporated into the light fitting without any visible change in the appearance of the light.
The light in the left is an excellent example of the type of lighting that is good for under cover car parks especially in the entrances and will replace 200w Induction or High Intensity Discharge lighting. With a light that use 42w.
The light does not leave the area in darkness when it deactivates but rather it set back to 5% output until the light is activated by motion.
Lights that operate the same, but have a different aesthetic appearance can be used in corridors, and small lights in fire escapes. These lights but Enlighten Australia also are available with emergency backup to operate on battery backup if the power goes out. With batteries that can easily be changed if required with out opening up the fitting or altering any wiring.
The lights from Enlighten Australia have a 7 year warranty, and considering the pay back period is in some cases as short as 2 years you really can't go wrong.
