EchoTech Marine XR15w Pro LED Lighting EchoTech Marine

EcoTech Marine XR15w Pro Coral


The newest generation of Radions radically re-define the simplicity, beauty and power of the LED light. The best aquarium LED light in the world just got better. Simply put, the G4 Radion the best thing since the G3 Radion. 

More Color
The Radion G4 features a whole new cluster. The re-balancing of proven colors combined with the addition of warm white and violet takes color rendition for your corals to the next level. Reconfiguration of the clusters compliments the all-new HEI lenses to deliver balanced color mixing better than ever before.

More Coverage

The HEI lenses on the G4 deliver more usable light area. This is accomplished by spreading light that would normally create an area of high PAR directly under the LED fixture and redirecting it to a significantly wider optimal area of intensity for coral health and growth. This will reduce shadowing in the aquarium as well as increase usable space for coral at all depths. 

More Civilized
EcoTech aims to produce the most minimally intrusive equipment available. The G4 continues to boast Radion’s sleek styling and small footprint but now also features greatly reduced operational noise. To achieve this the G4 incorporates a completely redesigned heatsink with new geometry and micro-fins.

More Control
More colors means more channels. The G4, like its predecessors, will be instantly recognized by EcoSmart Live and can be added to an existing or new ESL account either through USB or with the Reeflink. *Channel control is updated to match the new clusters and includes Violet and Warm White.

Generation 4 includes the most sophisticated lens design available. HEI lenses deliver the light uniformity and color mixing of a halide T5 combo without sacrificing the power and efficiency of the LEDs.

The G4 utilizes the most advanced top-bin diodes offered by CREE, OSRAM and Semiled to produce mind-blowing color rendition. The evolution of color in LED fixtures started with the original full-spectrum Radion. The G4 builds on this impressive legacy by further advancing both the available spectrum and channel control.

HEI Optics revolutionize LED output by providing unprecedented light distribution and spread. This lens geometry re-distributes the unnecessarily high par peaks that are otherwise present under the fixture.

How impressive is the new HEI lens design? Just compare the previous generations of Radion lenses, which utilized the best optical technologies of the time. Observing the respective PAR distribution of the reflector and TIR lenses, it is immediately apparent that HEI Optics offer a significant improvement from the perspective of providing usable coverage.

Quiet Active Cooling 
The G4 heatsink has been designed from the ground up to maximize surface area and allow for superior heat dispersion. Multiple channels provide unrestricted airflow. With such effective heat management, the need to actively cool the LED is greatly reduced and with it airflow and fan noise.

Web-Based Control Platform 
Control your equipment anywhere, any time. No matter where life takes you, your tank is right there with you. EcoSmart Live is cloud-based, so you can access it through a web browser on any computer or tablet with an Internet connection. Enjoy the peace of mind that your reef and its inhabitants are cared for and safe. (And you can say goodbye to installing software or staying on top of updates. New features are installed automatically.)

Customize the way your equipment operates
How much control you take is up to you. For example, use one of the many predefined Radion lighting modes—or create your own special modes by controlling each color individually. You can even change your Radion light’s intensity during the day and adjust lunar phases at night.

Take EcoSmart Live to the next level
The ReefLink is not necessary to access EcoSmart Live but you’ll love the flexibility and freedom it provides. By eliminating the need to connect your Radion by USB to a Mac or PC, ReefLink keeps your aquarium always connected, always accessible. With a ReefLink, you can use an iPhone, iPad and Android smart phones and tablets to control your Radion lights.
