Low Voltage Transformers. 1  A low voltage transformer literally transforms the standard line voltage in your home or business (120 or 277 volts) to a lower 12 or 24 volts. This lets you safely supply power to popular low voltage lighting systems like recessed can lights, pendant lights, puck lights and outdoor light fixtures. 123.
These lights are not suitable for retrofitting to existing low voltage halogen tranformers and are not considered in this article. Generally these lights do not have a MR16 fitting and are instead sold with a compatible hard wired transformer (a LED driver).ith low voltage leads of the same length, the light output from LEDs was very slightly better on the iron-core transformers with an average of 2.3% improvement in Lumen output-almost below the margin for measurement error.
