Abstract
Light emitting diode (LED) and compact fluorescent light (CFL) lamps are widely used because they are associated with low energy consumption and a reduced environmental impact. In the present paper, a study of the real consumption of these devices has been carried out. To do this, the active, reactive, distortion and apparent power and electrical efficiency for various lamps have been measured and calculated. The distortions produced in the network provoke the consumed energy to be in the order of 50–75% higher than that which appears in the commercial characteristics. This situation means that for its operation, it is necessary to generate and distribute an amount of energy much higher than that which is declared as the consumption of these lamps, and so far, this amount of energy is neither quantified nor invoiced. Additionally, groups of lamps have also been studied to check whether, when working together on the same network, there is a compensation phenomenon that reduces the negative effects of individual lamps. We have found that this compensation effect does not occur for the type of devices evaluated.

The distortion phenomena produced by various Light emitting diode (LED) and compact fluorescent light (CFL) lamps for domestic use and their effects on the actual consumption of electrical energy have been studied
Summary
It is evident that in recent years there has been greater awareness regarding the impact that our activity has on the environment. One of the efforts on which energy saving has focused is based on modifying basic behaviors, which individually may involve a small gesture, but collectively results in a qualitative change. In this regard, the institutions are promoting the replacement of the lamps used for lighting homes, looking for elements that provide a better lighting condition with lower energy consumption. 21 October 2009—published on 31 October 2009—a framework was established for the setting of ecodesign requirements for energy-related products [1] which highlights “Many energy-related products have a significant potential for being improved in order to reduce environmental impacts and to achieve energy savings through better design which leads to economic savings for businesses.
