12v Low Voltage Downlights

12v downlights have always been popular and remain so for good reason. Although the voltage is low these downlights are cheap to buy and give a powerful, crisp white light from the 12v lamp. Some people believe that because they are low voltage, they are more energy efficient than mains voltage downlights but this isn’t as straightforward as it might sound. In some cases this may be true but in others it is the opposite. Sadly, it is a fact that all mains transformers waste energy in converting 240v to 12v, however most 12v lamps give more light per watt than its mains voltage counterpart.
