The Best-In-Class Just Keeps Getting Better!

The newest generation of EcoTech Radion continues to lead the way in the industry with mind-blowing improvements in light output and color. With a new LED cluster, Hybrid Hemispherically Edge Illuminating (HEI2) optical system, and diodes pushing deeper into the UV spectrum; the G6 Radions are bound to become your new favorite LED reef light.


Why does BRS recommend the EcoTech Marine Radion?

Quite simply, EcoTech Marine Radions are the LED’s we most often choose to light our own tanks. With the chance to use just about any light we want, there are probably more Radions in use around BRS than any other LED fixture. Through years of experience, we’ve seen the proven results in our growing, thriving reefs.

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 Radions.


Features and Improvements to the Radion G6

Radions are the standard in aquarium lighting for a reason. Each generation has built upon the successful results of the last, incorporating the latest in design and technology to bring us a state-of-the-art light that blends proven results with greater ease of use. Ecotech Marine has spent significant time and effort in developing and testing lighting programs, such as the popular SPS AB+, that deliver maximum results from their fixtures and bring out the best in our corals. The Radion G6 incorporates a new Hemispherically Edge Illuminating optic system with redesigned LED placement to deliver beautiful shimmer, superior color mixing, even PAR, incredible spread, and even adjustable hues!

  • New HEI2 Optic System
  • Super-Wide 126.3 Degree Spread
  • 395nm Diodes for Ultimate Fluorescence
  • Rebalanced Color Channels and LED Mix
  • Even PAR & High Output-- Almost 4ft of Coverage Area
  • Moonlight & Weather Simulation
  • Proven CoralLab AB+ Spectrum
  • Fully Programmable
  • Wireless Mobius App control


Mind-Blowing Spread with HEI2 Optical System

The Radion G6 achieves its mind-blowing 126.3 degree spread through a new and improved optical system. EcoTech implemented a change to the primary lens on the LEDs, which then integrates with the geometry of the existing HEI (Hemispherically Edge Illuminating) secondary lens to increase the output from an already impressive 110.5 to an outstanding 126.3 degrees! The super-wide spread has an added benefit of increasing output by reflecting off the aquarium side glass walls and reflecting light back into the tank, thus reducing shadows and providing light to the undersides of corals. This means that you can now light your tanks with even less fixtures! The G6 has the highest average output out of all Radions and can provide even PAR across almost four feet of coverage area, making it perhaps the most efficient aquarium light made to date.


Blue vs. Pro

The Radion G6 BLUE has gotten even bluer! Adjustments to the diode mix and the addition of 395nm offer new depths of color intensity and increased fluorescence. With the G6, you now have the ability to tune the Blue between actinic and crisp to find the perfect aesthetics for your tank. 


The Radion G6 PRO is what you see as the lighting of choice in many public aquariums, aquaculture facilities, and coral spawning laboratories worldwide. It features a balanced LED mix with proven spectrums similar to the output of Metal Halide lighting.


Compact & Sleek, High-Quality Design

EcoTech Marine aims to produce the most minimally intrusive reef aquarium equipment available. The G6 continues to showcase Radion’s sleek styling, small footprint, and quiet fan with revolutionary heatsink. The Radion boasts a technologically superior design with premium quality components and unmatched customer support. Better yet, the Radion G6 is still backwards compatible with the extensive mounting options and accessories available to the previous generation of Radion, so you can still customize your lighting experience to fit your individual aquarium needs.


Mobius Control

More colors mean more channels, and with Mobius, programming and controlling your G6 is even easier and faster. Mobius means almost instant setup and programming. Local wireless control and programming can be accomplished with either current OS version iOS or Android smart device. Experience the ultimate app-based control at your fingertips-- no separate controller purchase required!


With the Mobius smart control platform, you can connect, control, and program your entire collection of EcoTech equipment easily with your iOS or Android smart device. That means centralized control of pumps, lights, dosing, and flow without needing to purchase expensive modules and controllers. The app's visual interface is intuitive and simplified-- the way aquarium automation should be. You can easily download Mobius for free from the App Store or Google Play.

Ecotech offers multiple types of mounting solutions for the G6 family of Radion LED lights. From full tank track systems letting you use multiple G6 Radion lights, to single light RMS mounting arms and hanging kits.

RMS Mounting Arm - For mounting a single light fixture over your tank. Lights may be mounted at 90-degree increments.

RMS Track System The 3 piece system lets you mount multiple Radion lights in a single track that lets you slide them back and forth to create the best coverage for your tank. The multi-light rail kit is available in lengths up to 8ft and is perfect for larger tanks, letting you use either a hanging kit to suspend the track system or the RMS Arm Kit for a tank mounting option. RMS multi-light kits work with both XR15 and XR30 model lights or a mixture of both.

RMS Hanging Kit If tank mounting is not an option for your multilight rail - or you prefer an even more minimal aesthetic - hang the multi-light rail.

Product Questions

How mean would I need to cover a 180G traditional tank?
Question by: Peter Starek on Jul 16, 2024, 7:32 PM
x2 XR30s should be sufficient for a standard 180 gallon tank.
Answer by: Grace (BRS Staff) on Jul 19, 2024, 11:44 AM
my tank is 96 length 36 height and 24 width how many of these lights do i need for proper spread? thank you.
Question by: Edvin Orujyan on Feb 8, 2024, 4:39 PM
Each of these lights has an absolute maximum spread of 48" x 48", but given the depth of your tank, I would suggest no less than 3 of these as the suggested spread is 30" for mixed reef applications or 36" for softies only to prevent shadowing and low light zones. If you are going for an SPS dominant system, I would even consider four to ensure you get optimal coverage.

I hope this helps!
Answer by: Taylor L. (BRS Staff) on Feb 16, 2024, 11:32 AM
I have a custom 140G dimensions 44"L x 24"W x 31"H. Would 1 light work for full coverage? And would i have enough light penetration?
Question by: Anthony McClain on Nov 21, 2023, 8:10 AM
The recommended spread for these lights is 30"x30" for lps and 36"x36" for soft corals. I would go with two of these to get proper light for your tank size.
Answer by: JJ Kress (BRS Staff) on Jan 19, 2024, 8:04 AM
Says Eyelid mounts included, so does that mean I can just run some cable through them to hang them or do I need to purchase the separate mounting kit?
Question by: A R on Jun 20, 2022, 11:13 AM
Thanks for asking. The included eyelets will allow you to hang the fixtures, or use clips to secure the lights. The separate mounting kit offers a nicer installation, but is not necessary. Let me know if you have any other questions, and have a great day.
Answer by: Chad (BRS Staff) on Jun 28, 2022, 8:07 AM
It says that the max light coverage is 48”x48” so 1 xr30 would be good for a 75 gallon?
Question by: Jason on Jun 2, 2022, 5:11 PM
Thanks for the question! This depends greatly on the application. If you are planning corals only under the light and within 30-36" from center then one will work. This is assuming low light corals, softies and LPS. For optimal spread that will allow for a variety of corals throughout the tank, 2x XR15 G6 Blues would be a better option.
Answer by: Kyle Thomas (BRS Staff) on Jun 7, 2022, 10:12 AM
Does this version connect to the Apex like the G4 did?
Question by: John on May 26, 2022, 12:27 PM
Hey there,
Thank you for reaching out to us. This does not connect to the Apex System.

Please let me know if you need anything further and take care!
