For any of your pool or spa lighting needs, we have selection available! The safety transformers are specifically designed to supply 12 volts to pool and spa lights, submersible fixtures and outdoor garden lights. There is a grounded shield between the primary and secondary windings to assure safe operation. The built in circuit protection will disconnect power to the transformer in case of defect or overload. They are available in a few different sizes to meet your aquatic needs. We have a great selection of bulbs, reflectors, wires and lenses available as well.
