EcoTech Radion XR15 Gen 6

EcoTech Marine Radion XR15 G6 Reef LED Light

The EcoTech Marine Radion XR15 G6 is a premium reef aquarium LED designed to deliver exceptional spread, even PAR, strong fluorescence and highly tunable spectrum control. Available in G6 Pro and G6 Blue, the XR15 is built for reef keepers who want powerful coral-focused performance from a compact fixture.

The G6 generation uses EcoTech’s HEI2 optical system, increasing the output angle to approximately 126.3° for wider coverage, smoother colour mixing and reduced hotspots compared with previous generations.

Key Features

• 95W maximum power
• Available in XR15 G6 Pro and XR15 G6 Blue
• HEI2 optics with approximately 126.3° spread
• Wide, even PAR distribution
• Strong UV, violet and blue output
• Excellent coral fluorescence
• Fully programmable
• Wireless control
• Moonlight mode
• Weather simulation
• Multiple mounting options
• Optional diffuser accessory
• Suitable for mixed reef and SPS-focused aquariums

HEI2 Optical System

The G6 uses EcoTech’s second-generation Hemispherically Edge Illuminating optics, designed to produce an extremely wide and even lighting field.

Compared with the previous G5 generation, the spread angle increases from approximately 110.5° to 126.3°, helping distribute light more evenly across the aquarium.

This wider coverage helps reduce:

• Harsh hotspots
• Deep shadowing
• Uneven PAR
• Colour separation

The result is a smoother, more natural-looking reef display with strong usable light across a wider area.

G6 Spectrum

The Radion G6 spectrum has been refined to increase useful blue and UV output while maintaining balanced full-spectrum performance.

Important wavelength ranges include:

• 395 nm – enhances coral and fish fluorescence
• 400–450 nm – strong blue and deep-blue output for fluorescence and photosynthesis
• 460–580 nm – balanced mid-spectrum output for colour rendition
• 665 nm – long-wavelength red output for colour balance and photosynthetic support

XR15 G6 Pro

The XR15 G6 Pro is designed for reef keepers who want a broader, more balanced full-spectrum appearance.

Its LED mix provides strong blue and UV performance while retaining more white, red and green output for a natural reef presentation.

LED Configuration

• 8 × Cool White
• 16 × Royal Blue
• 8 × Blue
• 2 × Red
• 3 × Green
• 2 × 395 nm
• 1 × 405 nm
• 2 × 415 nm
• 4 × 430 nm
• 4 × Warm White
• 1 × Moonlight

The G6 Pro is ideal for aquarists who want strong coral growth and fluorescence while maintaining a balanced daylight appearance.

XR15 G6 Blue

The XR15 G6 Blue puts more of its output into the blue and violet spectrum for reef keepers who prefer a deeper actinic look and stronger coral fluorescence.

LED Configuration

• 4 × Cool White
• 16 × Royal Blue
• 16 × Blue
• 1 × Red
• 2 × 395 nm
• 1 × 405 nm
• 2 × 415 nm
• 6 × 430 nm
• 2 × Warm White
• 1 × Moonlight

The G6 Blue is particularly well suited to reef systems where fluorescence and blue-heavy colour are the priority.

Coverage

The XR15 G6 is well suited to aquariums around 24–30 inches wide and deep, depending on mounting height, coral placement and desired PAR.

Its wide spread makes it suitable for:

• Mixed reef aquariums
• SPS-focused systems
• LPS reefs
• Soft coral tanks
• Frag systems
• Larger aquariums using multiple fixtures

Specifications

• Power Consumption: 95W
• Dimensions: 18 × 18 × 3.9 cm
• Weight: approximately 1.59 kg
• Input: 100–240VAC, 50/60Hz
• Peak Inrush Current: 1.3A

Pro vs Blue

Choose the G6 Pro if you prefer:

• A more balanced full-spectrum look
• Brighter whites
• More natural colour rendition
• Greater visual flexibility

Choose the G6 Blue if you prefer:

• Stronger blue output
• More coral fluorescence
• A deeper actinic reef appearance
• More emphasis on blue and violet wavelengths

The EcoTech Marine Radion XR15 G6 is an excellent choice for reef aquarists wanting premium spectrum control, exceptional spread, strong coral performance and a clean, compact LED fixture.
