The Mabel collection of low voltage transformers, by Yosemite Home Decor, with a 120-volt input and 12-volt output capacity, was designed with the HE1002 and HE1003 under-cabinet puck lights in mind. With a 75-Watt maximum, this model can accommodate up to three low voltage puck lights. UL-rated, this model is guaranteed safe for use. Clearly, this brand is the best of its kind in the market today.
