Full Details

Radion G4 Spec Sheet


HEI Optics

Revolutionary HEI Optics (Hemispherical Edge Illumination) are now incorporated in all G4 Radion LED lights. HEI helps deliver better uniformity, spread, and overall color mixing allowing the Radions to come very close simulating  Halide/T5 combos without any added heat or energy usage. The lens geometry of the HEI Optics offers a significant improvement over standard optics and even TIR lenses spreading the light over a greater area, allowing your tank to have a more even spread of light without any major hot spots.


Micro-Fin Cooling

The completely redefined heatsink of the G4 series of Radions now has Micro-Fin cooling creating more surface area allowing for a quicker heat transfer and dispersion allowing for more passive cooling, and less need for active cooling. Along with the heatsink's cooling fins, a computer driven, silent, IP55 cooling fan allows for active cooling over the Micro-Fins letting your light shine brighter and last longer!


EcoSmart Live

The web based interface lets you control all of your Ecotech Marine products through the cloud. Through your smartphone, tablet, or computer you can control the G4 family of Radion lights anywhere you have internet access. The ReefLink Controller creates a fully inclusive device management system, with the use of the Vortech propeller pumps, Vectra return pumps, and Radion lighting, create an authentic ecosystem that you can control right from your fingertips.

Ecotech offers multiple types of mounting solutions for the G4 family of Radion LED lights. From full tank track systems letting you use multiple G4 Radion lights, to single light RMS mounting arms and hanging kits.

Radion Hanging Kit - Mount a single Radion light quickly and easily. Radion Hanging kits have quick lock fasteners that let you adjust the height making it a great choice for frag systems, or acclimation systems.

RMS Mounting Arm - Mount your single Radion through a robust tank mounting system. The RMS Arm is by far the quickest and least obtrusive option that doesn't require drilling any holes in your walls or ceilings.

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 track system 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.


Note: Reeflink Controller required for use with EcoSmart Live. Also controllable through the Neptune Apex WXM Module.

  • Just great By Jerry on 11/1/2017

    I am new to reef lighting but so far it is an amazing and I have no regrets. Easy to set up with reeflink and its all been a great experience.
  • Awesome Functionality By WebCitz on 9/10/2017

    We have this over our frag tank in the office. It has great options once you start going through all the color profiles and setting up the automation. The lunar cycle is really cool. Not sure yet on how to get the thunderstorms to happen once in a while, but either way it is an awesome light. Easily covers the IM Fusion 20 gallon tank we have it over.
  • a lot of light By airwarf on 7/17/2017

    Super simple and sleek looking with the echotech mount on my 60g rimless cube. The ability to adjust spectrum, intensity, and many other effects on this lights daily program is amazing. It's honestly what everyone wants in a light.

    It's SUPER nice to be able to control this EchoTech product without a Reeflink unlike other EchoTech products.
  • Works great By Musical Reef on 5/8/2017

    I'm new to reefing, so I don't have much to compare this to, but as a new reefer, I found the lights easy to use and program and my corals are growing well. Honestly, what else could i ask for? They have some fun (lightning and disco) but useless features that are great for showing off to your friends :) The programming is nice and versatile, but a little buggy at first. Once you play around with it, you get to understand where their web interface has issues and ways to work around it. It's honestly not a big deal, but as a programmer I want to go in there and fix it! I did have an issue in the beginning where the application wasn't recognizing one of the units but a phone call to support and they fix it within minutes. Their service is great. I know some people get upset at the fact that they have to call service to begin with, but it looks like in all the reviews service handles their issue well. I also love the fact that they have templates that come with the program. I remember feeling lost when I first started and then saw the templates and sighed a big relief! I wish they would add more templates to their vortechs next. Two small complaints, first the price and the price of the mounts. I feel a little ripped off that their mounts are so much money especially after spending so much on the lights themselves. Second complaint is that the fans kick on more than I expected. Nothing bad, but I was hoping that at 50% usage they would never kick in. But being new to this hobby, maybe my expectations are not realistic.
  • Good light By B-Rock on 1/30/2017

    I recently purchased all ecotech pumps so I switched over to the radion from AI so I could use the reeflink and get them all working together. Other than the setup process (all on the reeflink side) the light preforms great. my only criticism is the lights cycle down and back up when you set a new schedule which my fish hate. But that may again be a reef link issue.
  • Super Happy with Light By sayitfast on 1/28/2017

    The light is great... very easy to setup... I do have the reeflink and its drop dead easy. I have the light on my frag tank and using the Coral Grow template is awesome and takes away much of the guess work. I like it!
  • “Awesome” By Robert on 1/24/2017

    With the reef link very simple to set up complete coverage everywhere! Just a amazing unit, worth every penny :)
  • Great lights for my 90 mixed By Doc E on 12/27/2016

    Love these lights just keep in mind that you must research and research to learn how to program for best results
  • Great light By Tyler on 12/11/2016

    This is the first radion I have ever owned but so far I'm very impressed by it. The setup of the light was very easy. I don't have the reef link but the light has held its program the whole month I've had it. I used one of the default light setups they have available and used the acclimation mode on it to get my corals used to this bright light. I have never seen my corals open up so much since after using this light. I will be buying my second one here soon in the upcoming weeks
  • At first it was great but I am not impressed By Nathan on 11/14/2016

    With the larger spread and better cooling I was impressed with this light, until it would get stuck in different modes and spectrums. I have a G3 that I love and have never had any problems with. My 3 week old G4 is junk! During a programmed daily cycle the light stops at one point and does not continue the cycle.
  • Nice light By Eric on 9/23/2016

    Setting up a 4'x2' LPS/softie (lower light) frag tank and plan on using 2qty XR15 Gen4. Got the first one in to test with the seneye par meter before committing to the 2nd.

    Using the light program/spectrum I plan to run at 100% (overall the light is running about 67% of total of all channels)- I measured 115par directly below the light (26" to light) and 80par in the very corner of the 2x2 area that this single light will cover. Very even spread at this distance to the light, lowering the light increased the par directly under the light, but lowers the par at the outer edges. My goal was about 50-100par, so I can actually run at less than full power on the spectrum I want. I am very pleased with this light.

Product Questions

Hi, does the Radion XR15w G4 Pro LED Light Fixture come with a goose neck or a mounting fixture?
Question by: Sunny on Mar 27, 2017 12:44:00 PM
Hey there,
The mounting options for the Radion fixtures are sold separately. Currently they have the RMS tank mounts, light tracks, or hanging kit options available.

Have a great day!
Answer by: Zack (Admin) on Apr 4, 2017 10:10:00 AM
I currently have XR15w G3 Pros on the RMS mounting arms. Will the new G4 fit on the same mounts?
Question by: Larry Leszczynski on May 15, 2017 9:53:00 PM
Ecotech is still using the same mounting options for the G4 lights, so your old mounts will work with the new lights!

Happy reefing!
Answer by: Zack (Admin) on May 17, 2017 4:34:00 PM
I have a tank 48 in L x 13 in w x 24 in H would two of these XR15 work? I have softies but mainly LPS, I do want to get into SPS
Question by: Robert on Nov 6, 2016 2:08:00 PM
Hey there, great question! I would say that two of these will work just fine on your tank, especially with the lower PAR demand corals like softies and LPS. However, depending on how you place them, you may see some minor shadowing on the edges or the center. :- )
Answer by: Randy (Admin) on Nov 8, 2016 5:08:00 PM
Are the hanging kit also comparible with the xr15w?
Question by: Ryan on May 31, 2017 4:31:00 AM
The Radion hanging kit will work for both the XR15 and XR30 models.

Happy reefing!
