High-wattage pool lighting systems require a transformer that can safely deliver consistent low-voltage power without overheating or voltage drop. The Intermatic PX300 300W Pool Light Transformer is designed to convert standard 120V input into safe 12V low-voltage output for larger or multi-fixture pool and spa lighting installations.

This transformer is commonly used when multiple pool lights, spa lights, or high-output fixtures are installed on the same circuit. Its higher wattage capacity allows it to support greater lighting loads while maintaining stable voltage, helping lights operate at proper brightness without stressing bulbs or wiring.

Built for outdoor pool environments, the PX300 is a dependable solution for both new lighting installations and upgrades where increased wattage capacity is required.

Supports Larger Pool Lighting Loads

As lighting systems expand, undersized transformers can struggle to deliver adequate power. The Intermatic PX300 provides up to 300 watts of capacity, making it suitable for pools with multiple lights or higher-wattage fixtures.

By delivering sufficient power, this transformer helps prevent dim lighting, uneven brightness, and premature lamp failure caused by voltage drop or overload conditions.

Safe 120V to 12V Voltage Conversion

Pool lighting systems rely on low-voltage operation to reduce electrical risk around water. The PX300 steps down standard household voltage to 12V, providing the safe output required for compatible underwater and low-voltage pool lights.

This regulated conversion supports safe nighttime operation and helps meet common electrical safety standards for pool environments.

Weather-Resistant Construction for Outdoor Installation

Transformers installed near pool equipment must withstand moisture, heat, and outdoor exposure. The Intermatic PX300 features a durable, enclosed housing designed to protect internal components from environmental conditions.

Its construction supports reliable, long-term operation when mounted near equipment pads, lighting junction boxes, or dedicated lighting enclosures.

Why Choosing the Correct Pool Light Transformer Matters

Proper transformer sizing is critical for lighting performance and safety.

Using a higher-capacity transformer helps:

• Power multiple pool lights reliably

• Prevent voltage drop across longer wire runs

• Maintain consistent light brightness

• Support safe low-voltage pool lighting systems

Selecting the right wattage transformer protects both lighting equipment and electrical components.
