LED lighting power supply for Fluval aquariums FV-4375 — compatible with FV-5169 and FV-5220

Replacement LED lighting power supply designed for Fluval aquariums, compatible with Fluval FV-5169 and FV-5220 LED fixtures. This power supply provides the required electrical connection and stable power input for LED modules used in freshwater and marine tanks. It is intended for equipment maintenance and replacement of original adapter units, enabling continued operation of aquarium lighting without modifying the fixture.

Advantages

The power supply delivers stable voltage and current to Fluval LED modules, reducing flicker and minimizing performance issues related to inconsistent power. It is sized to match the electrical requirements of compatible fixtures and designed for straightforward replacement of the original adapter. The unit is compact and external, which simplifies installation and keeps heat generation outside the aquarium environment.

Suitable for

• Replacing a failed or lost power adapter for Fluval FV-5169 LED aquarium lights
• Restoring reliable illumination in freshwater and marine aquarium setups
• Routine maintenance when original power supplies show signs of wear or instability

Key specifications

• Compatibility: designed to work with Fluval FV-5169 and FV-5220 LED lighting fixtures
• Output type: DC output suitable for LED modules
• Form factor: external adapter to be connected between mains and fixture
• Intended use: indoor aquarium lighting systems for freshwater and marine tanks
• Safety: designed to meet typical requirements for low-voltage LED power supplies (overcurrent/overheating protections typically integrated)

How to use

Disconnect the existing power adapter from mains and the Fluval fixture before installation. Connect the replacement power supply’s output connector to the fixture’s input socket and plug the adapter into an appropriate mains outlet. Ensure connections are secure and positioned away from water sources. After connection, power the unit and verify the LED modules illuminate steadily. If illumination is irregular, disconnect and check all connections and the outlet supply.

Usage recommendations

Place the external power supply in a dry, well-ventilated location away from direct contact with water and aquarium spray. Use only with compatible Fluval fixtures and rated mains voltage. Inspect the adapter and cable periodically for damage, and replace if any wear or abnormal heat is detected to maintain safe and reliable aquarium lighting.
