Installation and Care Recommendations:

Mount the Radion XR15 Freshwater Gen 4 securely above the aquarium using a compatible EcoTech Marine mounting system. A mounting height of approximately 9 inches above the water surface is a practical starting point, with adjustments based on aquarium dimensions, plant requirements, and desired coverage.

For newly established planted aquariums, begin with a reduced lighting intensity and gradually increase output as plants become established. Excessive lighting without adequate nutrients and carbon dioxide availability may encourage unwanted algae growth.

Program a consistent daily lighting schedule appropriate for your aquarium’s plant species. Many planted aquariums benefit from an initial photoperiod of approximately 6–8 hours, with adjustments based on plant growth and overall aquarium conditions.

Keep the cooling vents free from dust and obstructions to maintain proper airflow. Periodically inspect and gently clean the lens according to the manufacturer’s recommendations.

Important Compatibility Information:

The Radion XR15 Freshwater Gen 4 is designed specifically for freshwater planted aquarium applications. Its LED spectrum differs from the marine Radion XR15 G4 Pro, which is optimized for saltwater reef aquariums.

Advanced remote control through EcoSmart Live may require compatible legacy control hardware, such as EcoTech Marine ReefLink. Verify the supported control method before purchasing, particularly when integrating the fixture with newer aquarium control systems.

Mounting hardware and optional control accessories may be sold separately.

Recommended application: A premium freshwater aquarium LED light ideal for planted aquascapes, tropical fish aquariums, and hobbyists seeking customizable full-spectrum lighting with advanced scheduling and professional-quality illumination.
