ABSTRACT
Current LED technology is becoming a viable alternative to other energy efficient lighting solutions in a variety of applications which include external lighting, industrial and office environments. With careful selection, LED systems can deliver the qualitative design requirements without compromise to the overall visual comfort and ambiance of the space. LED characteristics of high light output, good light colour quality and rendering and engineered product efficiency are beginning to become comparable to fluorescent lighting systems, however, there is an indeterminate risk regarding the longevity and stability of LED operating characteristics simply because the latest LEDs have not been around long enough. They are relatively untested on the marketplace when compared to a proven technology of fluorescent.
