Radion XR15 Blue G6 — Compact 95W Actinic UV HEI2 126° Reef LED - EcoTech Marine

The EcoTech Radion XR15 Blue G6 is the compact reef LED light fixture of choice for aquariums from 24 to 30 inches. With a square format of only 7 x 7 inches, it delivers 95 watts of concentrated power in the blue and UV spectrum thanks to 51 carefully selected diodes. As the sixth generation of the Radion platform, the XR15 Blue G6 integrates new 395 nm UV diodes for unparalleled coral and fish fluorescence, with the exclusive HEI2 optical system offering a 126.3° diffusion angle — ideal for nano and mid-size reefs.

G6 Blue Spectrum — More Blue, More Fluorescence

The XR15 Blue G6 removes the green, cyan, and lime LEDs from the G5 to concentrate all power in the channels most useful for coral fluorescence and photosynthesis:

• 395 nm (UV): New diodes unlocking additional fluorescence in corals and fish — pigments invisible under previous generations
• 400-450 nm: Rebalanced cluster with more blue and deep blue for a customizable rendition between crisp and actinic via Mobius
• 460-580 nm: Reduced mid-range spectral output to concentrate power on wavelengths useful for photosynthesis
• 665 nm: Far red diode for complementary photosynthesis and visual color balancing

HEI2 Optics — 126.3° Spread

The Hybrid Hemispherically Edge Illuminating (HEI2) optical system of the G6 increases the output angle from 110.5° (G5) to 126.3°. The result is remarkably uniform PAR across the entire aquarium surface, with no hot spots or dead zones. The light reflects off the glass walls, reducing shadows and illuminating the underside of coral branches. A single XR15 Blue G6 covers an aquarium from 24 to 30 inches for soft corals, zoanthids, and LPS. For a mixed reef with demanding SPS, two XR15s side-by-side are recommended for optimal PAR coverage.

XR15 Blue vs XR15 Pro — What's the Difference?

The XR15 Blue G6 focuses on blue channels with 16 Royal Blue + 16 Blue for maximum fluorescence and actinic intensity. The XR15 Pro G6 offers a more balanced spectrum with 8 Cool White, 8 Blue, 3 Green, and more red — ideal for a full Metal Halide-like rendition and coral photography. Both models share the same 7 x 7 inch housing, the same power (95W), and the same 126.3° HEI2 optical system.

XR15 vs XR30 — Which size to choose?

The XR15 (7 x 7 in, 95W, 51 LEDs) is designed for aquariums from 24 to 30 inches — perfect for nano reefs, AIO, and mid-size tanks. The XR30 (11.8 x 7 in, 215W, 101 LEDs) covers aquariums from 36 to 48 inches and doubles the light output. For an aquarium over 30 inches, the XR30 is recommended. For long aquariums, two XR15s can provide more uniform coverage than a single XR30 due to better positioning of light sources.

Exploded View — Radion G6 Construction

The finned heat sink and silent fan maintain the LEDs at optimal temperature for maximum lifespan. The compact profile (1.5 inches in height) and anodized aluminum construction make the Radion G6 one of the most discreet LED fixtures on the market.

Mobius Control — Smart Programming

The free Mobius app (iOS/Android) offers full control of each LED channel. Program sunrise/sunset cycles, simulate cloud cover and thunderstorms, and download pre-configured profiles like the popular SPS AB+ directly from the community. Mobius also centralizes control of VorTech and Vectra pumps for a complete EcoTech Marine ecosystem.

Frequently Asked Questions

Is the Radion XR15 Blue G6 sufficient for growing SPS?

Yes. The XR15 Blue G6 delivers 95W with a blue and UV-rich spectrum, sufficient for SPS growth in a 24 to 30 inch aquarium. For a demanding SPS reef in a wider tank, two side-by-side XR15s offer better PAR coverage than a single unit.

What is the difference between the Radion XR15 Blue G6 and the XR15 Pro G6?

The Blue concentrates its power in the blue and UV channels to maximize fluorescence and actinic aesthetics. The Pro offers a balanced full spectrum with green LEDs and more warm white, similar to a Metal Halide rendition. Both have the same power (95W), the same 7 x 7 inch housing, and the same HEI2 optical system.

Is the Radion XR15 G6 compatible with G5 mounts and diffusers?

Yes. The G6 uses the same housing and heat sink as the G5. All RMS mounts (Single Arm, Multi-Light Rail, Hanging Kit) and G5 magnetic diffusers are fully compatible. A G6-specific RMS Slide adapter kit is required for the Multi-Light Rail system.
