EcoTech Radion XR15 G6 Pro vs Red Sea ReefLED G2 115

The Radion XR15 G6 Pro is the more capable fixture: a wider 126.3-degree HEI2 spread, deeper UV diodes, Mobius wireless control and native Neptune Apex integration through MXM. The ReefLED G2 115 is simpler and self-contained, with a Kelvin scale from 10,000K to 23,000K and full output across that range. Reef keepers who want proven coral results and flexible mounting tend to favor the Radion; owners who want a clean, app-free setup with Red Sea tanks favor the ReefLED.

  • Choose the Radion XR15 G6 Pro if you want the widest spread, deeper UV spectrum and Apex or Mobius control, and you plan to mount it with existing RMS hardware.
  • Choose the ReefLED G2 115 if you want a straightforward WiFi fixture with a Kelvin dial and full power across the whole color range, especially on a Red Sea tank.

What reviewers say

EcoTech Radion XR15 G6 Pro

Reefers treat the Radion line as a benchmark for coral growth and color, and the G6 Pro carries that reputation with its wider spread and balanced spectrum. Owners like the app control and Apex integration. The main complaints are cost and the coverage limits of a single unit.

What people mention
  • Light spreadPraisedOwners say the HEI2 optics fill a 24-inch area evenly with less shadowing than earlier Radions.
  • SpectrumPraisedThe Pro configuration is described as balanced and close to metal halide, with good coral color.
  • CoverageMixedOne fixture suits small tanks, but larger systems need several units, which adds up.
  • CostCriticisedBuyers call it pricey compared with budget reef LEDs.

Questions and answers

Which is better for a mixed reef?
Both handle mixed reefs. The Radion's wider spread and deeper UV suit tanks with varied coral placement and shadow-prone rockwork. The ReefLED's Kelvin dial makes it easy to run a balanced white-blue schedule.
Which covers a larger area?
The Radion. Its HEI2 optic spreads to 126.3 degrees, with a recommended 24x24 in footprint and up to 30x30 in. The ReefLED is rated at 24x24 in with 20 in spacing between units.
Do I need a separate controller for either?
No. The Radion runs on the Mobius app and also supports Neptune Apex through MXM. The ReefLED G2 115 has built-in WiFi control.
Which is better for a deep tank?
The ReefLED publishes about 150 PAR at 20 in and is rated to 24 in of water depth. The Radion has no single published depth rating, so plan its spread and mounting height around your rockwork.
Is the Radion worth stepping up to?
If you want the widest spread, deeper UV and Apex integration, yes. If you want a simple WiFi fixture with a Kelvin dial and full power across the range, the ReefLED covers that well.
Will either fit my existing mount?
The Radion is backwards compatible with existing RMS mounting hardware. The ReefLED uses Red Sea's own mounting system, so check your arm or bracket before switching.
