Full Product Description +

Low-voltage transformers are a critical safety component in pool lighting systems, ensuring proper voltage delivery while protecting users and equipment. The Intermatic PX100 100W Pool Light Transformer is designed to convert standard 120V power to safe 12V low-voltage output for pool and spa lighting applications.

This transformer is commonly used with underwater pool lights, spa lights, and low-voltage landscape lighting where consistent, regulated power is required. Its enclosed, weather-resistant design allows it to be installed near pool equipment while maintaining reliable performance under outdoor conditions.

Built for durability and electrical safety compliance, the PX100 is a trusted solution for both new installations and replacement of aging or failed pool light transformers.


Safe 120V to 12V Voltage Conversion

Pool lighting systems require low-voltage power to reduce electrical risk around water. The Intermatic PX100 steps down standard household voltage to 12V, delivering the appropriate power required for compatible pool lights.

This controlled voltage output helps prevent overheating, premature lamp failure, and electrical hazards, supporting safe nighttime pool operation.


Designed for Pool and Spa Lighting Applications

The PX100 is engineered specifically for pool and spa environments where moisture, heat, and continuous operation are common. Its 100-watt capacity supports multiple low-voltage fixtures when properly sized, making it suitable for residential pool lighting systems.

The transformer is often mounted near the equipment pad or lighting junction box for convenient integration into existing electrical layouts.


Durable, Weather-Resistant Construction

Electrical components near pools must withstand outdoor exposure. The Intermatic PX100 features a rugged, enclosed housing designed to protect internal components from weather and environmental conditions.

This durability supports long service life and reliable operation throughout multiple pool seasons.


Why Proper Pool Light Transformers Matter

Using the correct transformer is essential for both safety and performance.

Installing a dedicated pool light transformer helps:

  • Deliver safe low-voltage power near water

  • Protect pool lights from voltage damage

  • Maintain consistent light output

  • Support electrical code compliance

Proper transformer selection is a key part of safe pool lighting design.
