EcoTech Marine Radion XR15 G5 Pro LED Light Fixture

***Please Note: The new G5 lights require a specialized G5 X-Bracket/Slider for mounting with Multi-light RMS systems, and a G5 RMS Mount for over-the-rim tank mounting (both sold separately).

The EcoTech Radions have been a standard in aquarium lighting for a reason. Each generation incorporates the latest in design and technology to yield a a state of the art product with proven success. With the new Radion G5 model, the evolution continues.

  • Optimized LED Placement - Geometric LED placement produces a wide but even PAR distribution and a balanced intensity to reduce hot-spots and benefit coral health.
  • Next Level HEI Optics - Hemispherically Edge Illuminating Lens Technology improves spread and color mixing without sacrificing shimmer, giving the reef a realistic underwater appearance.
  • Moonlight Mode - Dual color dedicated to moonlight channel for nighttime aquarium viewing.
  • Advanced Heat Management - An all new fan design keeps the G5 cooler and quieter than ever before.
  • Integrated Dust Protection - Mesh guard to keep dust out of the Radion fan and heat sink.
  • Uni-body Lower Cover - Tighter tolerances and the removal of potential water ingress weak points improve longevity in moisture rich environments.

Beyond Peak PAR

The best aquarium lights excel at two things: providing the light that marine life needs to grow and thrive, and accomplishing the goals and desires of the aquarist. The Generation 5 Radions do both.

Technological improvements in LED and optics technology deliver wider, even spread at optimum PAR levels. Balanced light spread facilitates coral placement and delivers more usable real estate without risking over-lighting directly beneath the fixture.

Impressive performance improvements in the G5 platform come from moving energy wasted in hot spot PAR to total luminance. The result is a significant increase of usable in-tank light, more even converge, and visually brighter more pervasive light in the aquarium.

The new Radion G5 lights deliver the following:
  • PAR at the ranges needed
  • Wider spread
  • Overall 35% more light
  • Beautiful Caustics
  • Smooth color mixing

Pro vs. Blue

The new G5 Radions come with two amazing options: G5 Pro & G5 Blue.

G5 Pro From aquaculture to the home aquarium, there is a high likelihood that the coral you know and love has been grown or "colored-up" under a generation of Radion Pros. The Pro series is powerful, flexible, and proven.
  • Full Spectrum
  • 10 Channels
  • PRO Balanced LED Mix
  • At 100%: Proven Halide Spectrum and Previous PRO Spectrum
  • Flexible Output
G5 Blue The aquarium light for those who know exactly what they want. The Gen 5 Blue is full spectrum, but LED selection favors the blue channels and high output at the proven AB+ spectrum.
  • Full Spectrum
  • 10 Channels
  • Blue Dominant LED Mix
  • At 100% Proven Corrallab AB+ Spectrum
  • Easy Spectrum

Yes, I would recommend this.

Great light but check your packaging!

Pros: Easy set up, has proven settings ready to go!

Cons: Manufacturing packaging mishaps

Great light but..
Ordered the pro version and received the blue one. The packaging and serial number match to the light that I got a pro version. After extensive research I realized I had received the blue version because of the blue heat sink on the light fixture. The light has been set up on an established reef tank and I have sold my old light fixture that this one has replaced. So I never sent it back nor contacted marindepot. It’s not marinedepots fault it’s ecotech. I love the light either way and am happy with it but just make sure your actually getting the version you order.

A Pros light choice

Pros: Premium powerful light, Programming built for specific coral types, Mobius

There's a reason why pros choose Radions. The light is superb on my SPS/Mixed tank.

Love the Mobius Corallab AB program - set it and forget it. Will never go back to another light!
