Description This Pool Safety Transformer is suitable for direct connection to underwater Pool and Spa Lights. A pool light safety transformer is a static device that converts electrical energy from one circuit to another. Typically reducing standard household voltage to a lower and safer voltage for outdoor pool lights. This can allow for long wiring runs without voltage drop and can also help reduce shock hazards. It can be used to power a variety of outdoor lights. This includes floodlights, fountains, garden lights, spas, and jacuzzis.  ENHANCED SAFETY FEATURES – Grounded shield between primary and secondary windings ensures safe operation, while built-in circuit protection disconnects power in case of overload, guaranteeing user safety.
