EcoTech Marine Radion XR15 G6 Pro LED fit check
EcoTech Marine Radion XR15 G6 Pro LED is a 105W reef light listing about 24x24 in of coverage and roughly 330 PAR at 18 inches. That clears ReefCrafter's PAR targets for soft coral, LPS, mixed reef, and SPS tanks. Tanks wider or longer than 24x24 in need a second fixture or a mounting plan that spreads light.
EcoTech Marine Radion XR15 G6 Pro LED: fits roughly 30-75 gallon systems. Specs, compatibility math, sizing risks, and alternatives before you buy.
Who it is for
Good fit for
- ✓ 30-75 gallon systems, per the catalog fit range.
- ✓ Soft coral (50-150 PAR), LPS (100-200 PAR), mixed reef (150-250 PAR), and SPS (250-350 PAR) goals at about 18 in depth.
Not a fit for
- ✕ Tanks under about 30 gallons; it is sized above them.
- ✕ Systems over about 75 gallons without adding capacity elsewhere.
- ✕ Footprints larger than about 24x24 in from one unit.
Listed features
- full G6 spectrum incl deep UV
- HEI2 optics
- Mobius app
Compatibility math
Coverage and PAR
Example: A common 75g footprint is 864 sq in; this fixture lists about 576 sq in and 330 PAR at 18 in.
ReefCrafter checks spread and intensity separately because a bright hotspot still leaves dim edges.
Risk notes
- The common mistake is buying a light that grows soft corals now but cannot support the mixed or SPS reef the keeper already wants.
- Large or SPS-heavy tanks may need multiple fixtures even when one light technically fits the gallons.
Professional fit context
- Match coverage width, coverage length, PAR at depth, mounting plan, and fixture count.
- EcoTech Marine Radion XR15 G6 Pro LED fits roughly 30-75 gallon systems; confirm that range against the final display volume, sump volume, and livestock plan.
Alternatives to compare
- AquaIllumination Hydra 32HD Reef LED Black
320 PAR at 18 in vs 330: less intensity, suited to lower-light corals.
- Orphek Atlantik iCon
350 PAR at 18 in vs 330: more intensity for higher-light corals.
- EcoTech Marine Radion XR15 G6 Blue LED
290 PAR at 18 in vs 330: less intensity, suited to lower-light corals.

Questions
Can the EcoTech Marine Radion XR15 G6 Pro LED grow SPS corals?
Its listed 330 PAR at 18 inches meets ReefCrafter's SPS target of 250-350 PAR near the coverage center. Edges and deeper rock will read lower, so place SPS high and centered.
How large a tank does one EcoTech Marine Radion XR15 G6 Pro LED cover?
The listing gives about 24x24 inches of coverage. A tank footprint larger than that needs another fixture or a raised, spread mounting plan to avoid dim edges.
What tank size is the EcoTech Marine Radion XR15 G6 Pro LED for?
ReefCrafter's catalog fit range for it is 30-75 gallon systems. Confirm that against your final display volume, sump volume, and livestock plan rather than the box label alone.
What should I compare the EcoTech Marine Radion XR15 G6 Pro LED against?
AquaIllumination Hydra 32HD Reef LED Black (320 PAR at 18 in vs 330: less intensity, suited to lower-light corals); Orphek Atlantik iCon (350 PAR at 18 in vs 330: more intensity for higher-light corals); EcoTech Marine Radion XR15 G6 Blue LED (290 PAR at 18 in vs 330: less intensity, suited to lower-light corals).
