Abstract
Contemporary lighting systems are unconditionally based on Solid State Lighting incorporating the newest LED technology. Where older lighting systems are in operation, the fastest way how to increase the energy performance, to save costs for lighting energy and to enhance various quality features of lighting is to apply retrofit LED lamps as replacement for other lamp types in existing luminaires. This measure is not free of shortcomings although due to marketing reasons disadvantages are not highlighted. This paper aims to give an overview of the LED retrofits most widely used in interior lighting and to highlight their key technical parameters in comparison to lamps they are replacing. Parameters and features of LED retrofits will be critically analyzed, including the comparison of operational costs and calculation of the real cost benefits of the LED retrofits.
