In the field of lighting technology, the choice of lighting has shifted from conventional incandescent and fluorescent to LED (Light Emitting Dode) lighting. Many businesses have yet to take full advantage of LED lighting technologies to address visual comfort problems for occupants. The current focus of installations and retrofitting jobs is only on dollar returns and energy-saving measures. By defining a range of vulnerabilities and discrepancies, this paper reviews the typical criteria affecting occupant visual comfort and shifts gear into those that are fundamental to healthcare setup. Issues such as the importance of daylight introduction into hospital wards and the benefits of choosing correct correlated colour temperature are discussed, among others discomforts. LED lighting technology has advanced immensely by offering flexibility to build a lighting system that meets the environmental requirements of the end-user. Lighting technology and approach are shifting to a new paradigm by focusing not only on vision but also human psychophysical wellbeing in interior spaces. A balance must exist between energy efficiency and visual comfort factors.

As with any other product, having electricity of a certain quality is very important for consumers. Its quality has become the key feature that can be disturbed by loads based on power electronic devices. Electricity producers are striving to provide reliable and quality electricity supply to consumers. Public lighting systems that are based on LED lighting technology can potentially positively or negatively affect the power quality because they contain power electronics components in LED drivers. Because of that, two 7-day measurements were conducted on the same public lighting branch but with different lighting technologies (high pressure sodium, known as HPS and LED technology). Results of the measurements were analysed and compared. By analysing the results, other problems were also identified by using LED lighting technology. These problems are addressed in the conclusion of the paper.
