LED lighting has known a tremendous development over the past two decades, creating opportunities for facilities managers to make important savings without compromising on the quality of their lighting systems.
The article makes a direct comparison between current lighting solutions and advanced LED technologies. Until not very long ago most big buildings were using metal-halide or florescent lighting solutions. While these technologies weren’t bad at all, the new LED lighting systems have proved to be better in terms of energy and cost savings.
The LED lamp is about 40-60% more efficient than fluorescent or metal, thus enabling building managers to make savings by needing fewer lamps than in the case of traditional solutions. For instance, a metal-halide lamp lasts for about 20,000 hours. This lamp features 60% lumen maintenance. On the contrary, a LED lamp has a lifespan of 1000,000 hours, featuring a lumen maintenance of 92% by the half of its life. This means LED is much better than the above mentioned example of metal lamps.
All these mean that LED lighting offers much better quality for much longer time.
Another great advantage of LED is that it minimises light pollution thanks to its ability to target the surface of various objects such as doorways and parking lots. This is a very important feature for residential areas, something traditional lighting systems can’t provide.
Add to all these the fact that indoor lighting is able to come very close to recreate natural daylight, and you’ve got a winner. Thanks to LED lighting, interiors can be more welcoming and easier on the eyes of people working inside those buildings, as well as for visitors.
There are also other significant advantages to using an automated lighting system. Facility managers can oversee their entire area from a software programme, monitoring various parameters such as the wattage output for each assigned area. They can set alerts to help them know when they have to schedule maintenance works or repairs. By using such systems, they can save up to 10% of the energy output, therefore reducing the maintenance costs of the facility.
