Classification of cartridges for electric chandeliers and lamps

When choosing a cartridge for a chandelier, you should initially decide on the type of lamps that you will use. Most often chosen between halogen and conventional incandescent lamps. Today on the market, an electric cartridge for halogen lamps is presented in various configurations. The most popular are electric cartridges, on the packaging of which there is a marking G4 or G9, GU10, as well as, as an option, R7S. All these cartridges are allowed for use in domestic electric networks, but with one reservation.
