Description: This electronic transformer, changing from AC 220V-240V to AC 12V, it could protect the low voltage light bulbs or lamp beads. it is very durable to use, and easy to install, the red lines are input line, the white and gray lines are output line. And this transformers are suitable for all low voltage G4/G5.3 12V quartz m(halogen) light bulb, lamp beads, or suitable for MR11/MR16 quartz (halogen) lamp cup' matched lighting. Features: This transformers are needed instead of standard 220V-240V to 12V transformers commonly used for quartz/halogen bulbs. Without an transformer there is a possibility that the low voltage halogen lamp will either not work or flicker. If an low voltage halogen lamp does work with a normal voltage, the halogen light will have a significantly reduced their lifespan and maybe could break after only a few hours. This transformers are suitable for all low voltage G4/G5.3 12V quartz (halogen) light bulb, lamp beads, or suitable for MR11/MR16 quartz (halogen) lamp cup' matched lighting. These transformers are genuine and fully approved with the CE safety mark. With excellent quality and fine workmanship, very sturdy and durable to use.
