Radion XR30 G6 Pro LED Light Fixture - EcoTech Marine

Radion XR30 G6 Pro Expert Buying Guide

The EcoTech Marine Radion XR30 G6 Pro is designed for reef keepers who need broad coverage from a relatively compact fixture while retaining detailed control over spectrum, intensity, and scheduling. Its recommended light spread is 36 by 30 inches, with a listed maximum spread of 48 by 30 inches. Those dimensions make it particularly relevant for wide aquariums and multi-fixture installations where reducing dark gaps is a priority. Coverage should still be planned from the aquarium’s actual length and front-to-back width rather than its gallon rating. Rock structure, coral placement, mounting height, and the light demands of the animals remain important when deciding whether the nominal footprint is sufficient.

The defining change in the G6 optical system is its 126.3-degree spread. EcoTech combines a new primary LED lens with the geometry of the Hemispherically Edge Illuminating secondary lens to create the HEI2 system. The preceding spread figure was 110.5 degrees, so the G6 is intended to distribute light over a wider area. The source also describes side-glass reflection as a way light can return to the aquarium, helping reduce shadows and illuminate coral undersides. This broad distribution is useful for large colonies and branching aquascapes, but the maximum 48-by-30-inch figure should not automatically be treated as the ideal SPS footprint. The more conservative 36-by-30-inch recommendation is the better starting point for fixture-count planning.

The Pro model is the balanced-spectrum member of the G6 family. Its 100 LEDs include 32 Royal Blue, 16 Blue, eight 430nm Violet, four 395nm UV, two 405nm UV, four 415nm UV, 16 Cool White, eight Warm White, six Green, and four Red diodes. This mix provides considerably more white, green, and red representation than a reef light configured primarily around blue presentation. EcoTech describes the Pro spectrum as similar to the balanced output associated with metal-halide lighting, and notes its use in public aquariums, aquaculture facilities, and coral spawning laboratories. That makes the Pro the more appropriate G6 choice when broad spectral balance is more important than starting with the bluest possible appearance.

The distinction between Pro and Blue should be treated as a spectrum and presentation decision, not as a simple ranking. The G6 Blue is configured for a bluer appearance, with tuning between actinic and crisp looks and an emphasis on fluorescence. The Pro retains blue, violet, and UV coverage, including 395nm diodes, but combines those wavelengths with a larger balanced mix of cool white, warm white, green, and red. An aquarist who wants a daylight-capable display, balanced visual rendering, or a spectrum similar to lighting used in institutional and aquaculture settings has a clear reason to choose Pro. Someone whose overriding preference is a heavily blue presentation should compare the Blue model before committing.

For SPS planning, the included spectral tools are only one part of the decision. EcoTech identifies CoralLab AB+ as a proven spectrum and states that it has invested in developing and testing lighting programs such as SPS AB+. This gives XR30 G6 Pro users an established program from which to begin rather than requiring every color channel to be designed from scratch. It does not eliminate the need to choose an appropriate intensity, schedule, mounting position, and fixture count for the specific reef. The source does not provide a universal PAR target or an SPS-specific coverage guarantee, so those values should not be inferred from the 36-by-30-inch recommended spread alone.

Mounting height is central to obtaining the intended distribution. EcoTech recommends positioning the XR30 G6 Pro eight to ten inches above the aquarium. That range is the source-supported starting point for using the HEI2 optic and its wide spread. Raising or lowering the fixture outside that range may change how its light overlaps and reaches the aquarium, but the supplied information does not quantify those changes. Before installation, check that the selected support can position the 11.8-by-7-by-1.5-inch, 4.5-pound fixture at the recommended height. Also account for the 13-foot cable when choosing locations for the light, power supply, and available electrical connection.

EcoTech provides several mounting approaches for different layouts. The RMS Mounting Arm supports one fixture and allows the light to be mounted at 90-degree increments. For larger reefs, the three-piece RMS Track System holds multiple Radions and lets the fixtures slide along the track to refine spacing and coverage. Multi-light rails are available in lengths up to eight feet and can be suspended with a hanging kit or supported with an RMS Multi-Arm Kit. These multi-light systems accept XR15 and XR30 fixtures, including a mixture of both. A hanging kit is another option when a tank-mounted arm is unsuitable or a suspended installation is preferred. Eyelet mounts are included with the fixture.

For a multi-fixture reef, begin with the recommended 36-inch lengthwise coverage per XR30 rather than spacing lights around the maximum 48-inch figure. For example, two recommended footprints nominally span 72 inches when arranged along the length of a 30-inch-wide aquarium. That is a layout calculation, not a promise that two fixtures will satisfy every 72-inch reef. Dense SPS colonies, tall rock formations, perimeter coral placement, and the desired overlap between adjacent fixtures can all affect the final arrangement. The track system is particularly useful in this context because the fixtures can be moved back and forth after installation instead of being locked permanently into one position along the rail.

Programming is handled through the free Mobius app on a current-version iOS or Android device. No separate controller is required for local wireless setup and programming. Mobius provides control over the fixture’s colors, intensity, and schedule, while the XR30 G6 Pro also supports moonlight and weather simulation. The same platform can centralize compatible EcoTech lights, pumps, dosing equipment, and flow devices. For experienced users, the key advantage is the ability to manage the balanced Pro diode mix rather than accepting one fixed visual output. CoralLab AB+ offers a logical SPS-oriented reference, while manual adjustments can be used when the goal is a different balance between actinic fluorescence and a crisper, whiter presentation.

Neptune Apex users can integrate the XR30 G6 Pro through the optional MXM module. MXM places supported EcoTech and AquaIllumination pumps and lights under wireless Apex and Apex Fusion control, reducing the need to move between separate applications. The source does not describe direct Apex operation without MXM, so the module should be included in the equipment plan if Apex Fusion is intended to be the primary interface. Aquarists who do not use Apex can operate the fixture through Mobius without purchasing a separate controller. This makes the control decision straightforward: Mobius is the native local wireless route, while MXM is the specified bridge for an Apex-centered system.

Maximum variable power usage is listed at 215 watts, with a 100–240VAC, 4.0A, 50/60Hz input. Because usage is variable, 215 watts is a ceiling rather than a statement that the fixture continuously consumes that amount under every program. Power planning for one or more XR30 units should use the listed maximum where circuit capacity is being considered, while recognizing that the source provides no consumption figures for individual intensity levels or schedules. The fixture uses a quiet fan and a heatsink within its low-profile housing. No cleaning frequency or service interval is provided, so maintenance timing should follow EcoTech’s current instructions rather than an assumed schedule.

When moving an established reef to the XR30 G6 Pro, avoid treating settings from another fixture as directly interchangeable. The G6 combines high output, a 126.3-degree optic, broad color representation, and rebalanced channels, so an identical percentage or schedule from a different light does not establish equivalent delivery. Record the existing photoperiod, visual spectrum, fixture positions, and coral locations before changing hardware. Use the XR30’s programmability to make deliberate changes rather than simultaneously altering mounting height, spectrum, intensity, and duration without a clear reference. For a balanced SPS display, start planning around the recommended eight-to-ten-inch mounting height, 36-by-30-inch footprint, and CoralLab AB+ spectrum, then evaluate the aquarium’s specific layout.
