LED lighting useful information

LED (Light Emitting Diode). There are two types of LED lighting; Mains voltage and Low voltage, both of which operate on DC voltage via converters, either in the lamp itself or in the Driver.Mains voltage LED lamps are simple and can be used to replace a conventional light source, when they both have the same lamp holder requirements. (The most popular change is using a GU10 LED in a GU10 fitting. Here you will be substituting LED for a Halogen light source, so the level of illumination will be much lower).
