Balboa 59915 LED Tub Light Transformer Kit | 120V to 12V Whirlpool Bathtub Light Transformer

Bring Your Whirlpool Tub Lighting Back to Life

If your whirlpool bathtub light has stopped working, flickers, or won't turn on, the problem may not be the LED light itself—it may be the transformer.

The Balboa 59915 LED Tub Light Transformer Kit safely converts standard 120-volt household power into 12-volt low voltage, providing reliable power for compatible LED bathtub lighting systems. This transformer is commonly used in whirlpool bathtubs, air baths, hydrotherapy tubs, and select spa lighting applications.

Replacing a failed transformer is often a much less expensive solution than replacing the entire lighting system.

Restore Your Tub Lighting

This transformer helps restore:

• LED Tub Lights
• Multi-Color LED Lights
• White LED Lights
• Safe 12-Volt Power
• Reliable Light Performance

What Does a Tub Light Transformer Do?

Most whirlpool bathtub LED lights operate on 12 volts for safety. The transformer converts incoming 120-volt household power into the low voltage required to safely operate your tub light.

If the transformer fails, your tub light may stop working even though the LED light assembly is still good.

Common Signs of a Failed Transformer

Your transformer may need replacement if you notice:

• Tub light won't turn on
• LED light flickers
• Dim lighting
• Intermittent lighting
• No voltage at the light
• Burnt transformer
• Water damage
• Random loss of lighting
