This class 2, UL & cUL wet location listed enclosed electronic transformer is used for the product. Class 2 transformers are intrinsically safer transformers because they are compartmentalized to allow no greater than 5 amps of current to be drawn on each compartment. The enclosure cover contains weatherproof sealing and is easy to remove. This transformer has a low minimum load requirement of 1W to allow the use of LED products. Maybe dimmed using an electronic low voltage dimmer.
