The newest generation of Radions radically redefine 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 is the best thing since the G3 Radion.

More Radion

More Color

The Radion G4 features a whole new cluster. The rebalancing of proven colors combined with the addition of warm white and violet, takes color rendition for your corals to the next level. The 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 least intrusive equipment available. The G4 continues to boast Radion’s sleek styling and small footprint but now also features greatly reduced operational noise. The G4 incorporates a completely redesigned heat sink with new geometry and micro-fins that makes the cooling system less noticeable.

More Control

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

Hemispherical Edge Illumination

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.


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

Quiet Active Cooling

The G4 heat sink has been designed from the ground up to maximize surface area and allow for superior heat dispersion.  Multiple channels provide unrestricted airflow. This effective heat management greatly reduces the need for active cooling, which decreases fan and airflow noise.


Single Arm RMS

These two specialized kits are designed for XR15 and XR30 model Radions. Each kit contains everything needed to mount a Radion light on almost any standard or rimless tank.

Each kit contains multiple sliding rails and a rotatable x-bracket, allowing you to easily position your Radion precisely where you need it.

Multi-Light RMS

The Multi-Light RMS offers a customizable multi-light mount solution for Radion XR30 and Radion XR15 lights. The Multi-Light RMS system features:

  • Built-in cable management
  • Compatibility with rimmed, rimless and euro-braced tanks
  • Rigid yet lightweight construction
  • Anodized aluminum finish
  • Slide mounts for horizontal and rotational adjustment
  • Optimal mounting for Radions at approximately 7 inches (18 cm) above the edge of the tank

Web-Based Control Platform

EcoSmart Live is the cloud-based equipment command center from EcoTech Marine. Control and customize your Radion LED lights and VorTech propeller pumps any time, anywhere. All you need is an Internet connection and a web browser (Chrome, Firefox or Safari). And because it’s all stored in the cloud, your connection is always secure and your data is backed up to save your valuable custom programing information.

By all means, let the power go to your head.

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.
