Low Voltage Pool Lighting Transformers

Low voltage pool lighting transformers step down standard 115V household current to 12V, 13V, or 14V to safely power underwater and landscape lighting around your pool. Intermatic's PX series is one of the most common — available in 100W, 300W, and 600W configurations depending on how many fixtures you are running. Pentair and Hayward also offer wall-mount transformers designed to pair directly with their light systems.

When replacing a lighting transformer, match the wattage to your total fixture load and verify the output voltage matches your lights. Running too many fixtures on an undersized transformer will shorten its lifespan. For the fixtures themselves, browse our pool lights collection.

Control System & Equipment Transformers

Beyond lighting, transformers are a critical component inside pool control systems, salt chlorinators, heaters, and spa packs. Units like the Pentair EasyTouch, Hayward AquaRite, Jandy JXi, and Balboa spa systems all rely on internal transformers to step voltage down for their circuit boards and sensors. These are typically direct OEM replacements specific to a make and model — not interchangeable across brands.

When ordering a control system transformer, always cross-reference your equipment's model number to confirm compatibility. If your control panel is powering on but not responding correctly, a failed transformer is one of the first components worth testing. For scheduling and automation parts, see our pool time clocks collection.

Frequently Asked Questions

What wattage transformer do I need for my pool lights?
Add up the wattage of all fixtures on the circuit and choose a transformer rated above that total. Common residential setups use 100W to 300W transformers. Always leave some headroom above your total load.
Are pool control system transformers interchangeable?
No. Control system transformers are typically OEM-specific and designed for a particular make and model. Always cross-reference your equipment's model number before ordering a replacement.
How do I know if my pool transformer is bad?
Common signs include lights that won't turn on despite good bulbs, a control panel that powers on but behaves erratically, or no output voltage when tested with a multimeter. A transformer that runs unusually hot or shows visible burn marks should be replaced immediately.
