Ecotech Marine Radion XR15W Gen 4 LED Light

The Generation 4 of the Radion has the new HEI optics allowing for more even spread and reducing hotspots and more channels and more power.


Radion XR15w Gen 4


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 Colour

  • The Radion G4 features a whole new cluster. The re balancing of proven colours combined with the addition of warm white and violet, takes colour rendition for your corals to the next level.
  • The reconfiguration of the clusters compliments the all-new HEI lenses to deliver balanced colour 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 colours 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.

  • HEI Optics

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

  • Comparison

    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 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.

  • Specifications:

  • INPUT: 100-240VAC, 2.5A; 50/60Hz
  • DIMENSIONS: Length: 7 inches (18 cm), Width: 7 inches (18 cm), Thickness: 1.5 inches (3.9 cm)

  • Powerful, full colour & endlessly controllable, the Radion stands alone.
