Getting the most out of LED sources
As the usage of LED lighting widens and its immense potential becomes more generally recognized, the lighting industry needs to pay growing attention to the needs of the end user and the quality of the visual environment.

The lighting industry has gradually developed, adopting widely accepted standards. By adhering to these standards, the industry has guaranteed that users and their environments are provided with the optimal solutions to ensure their physiological and mental wellbeing.

The rapid development, however, of LED solutions and other advanced luminaires requires that those designing and providing future lighting solutions pay much more attention to the actual needs of the final consumer. Whether it is a municipality, which requires outdoor lighting solutions or a developer who is building an office building and is looking for interior lighting solutions, they should guarantee that they meets the users' needs.

As the LED industry is still young and has not yet developed the appropriate standards, there is a growing need to ensure that the use of LED lighting does not hinder visual performance or cause visual discomfort.

LED is an excellent lighting source, but in order to maximize its advantages it is necessary to use it properly and to integrate it with the right optical system. The LED must be installed in the correct fixture to guarantee proper heat dissipation and light distribution to create the optimum lighting environment.

It should also be noted that there are serious differences in the quality of different LED solutions. Some low-cost LED lightning solutions don't last long and others don't generate the required energy savings. In some of the cheaper LEDs sold in the market, the light quality tends to deteriorate in a relatively short time.

Designing the right lighting environment can substantially improve worker productivity, while a problematic lighting environment will yield the exact opposite.

Users of LED lighting installations should ensure that they will have the right color rendering and unified glare rating (UGR) in order to guarantee that users benefit from a visual environment that is specifically designed for their specific needs.
