Description: This electronic transformer, changing from AC 220V-240V to AC 12V, it could protect the low voltage halogen light bulbs or lamp beads. it is very durable to use, and easy to install, the red lines are input line, the white lines are output line. And this transformers are suitable for all low voltage halogen light bulb, lamp beads, but no suitable for LED bulb. Features: This transformers are needed instead of standard AC220V-240V to AC12V transformers commonly used for halogen bulbs. Without an transformer there is a possibility that the low voltage led lamp will either not work or flicker. If an low voltage LED lamp does work with a normal voltage, the led 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 halogen light bulb, lamp beads, but not for LED bulb. These transformers are genuine and fully approved with the CE safety mark. With excellent quality and fine workmanship, very sturdy and durable to use.
