Most of this guide’s lineup is still moving through final publishing at IndieFur, though four items are now published and available to order: the Radion XR30 G6 Pro, the XR30 High Intensity Lens Kit, the RMS XR15 Tank Mount System, and the Multi-Light RMS Arm Kit. We’re covering the rest of the lineup anyway because the Radion lineup is a common question from reef keepers researching lighting upgrades, and we want this guide accurate as more listings go live rather than published later with guesswork. Where a product doesn’t yet have a live product page, we’ve described it without a link; check back or contact us directly if you want current availability on a specific item. If you’re also looking at auto-dosing or monitoring equipment from the same ecosystem, our Neptune Systems Reef Controller & Auto-Dosing Guide covers the Apex platform, including the MXM Mobius module that bridges the two brands (more on that below).
The Radion G6 fixtures
EcoTech’s current flagship line is the Radion XR30 G6, available in two variants: the Radion XR30 G6 Pro, now published at IndieFur, and the Radion XR30 G6 Blue, both built for larger or deeper reef tanks needing higher output. For smaller or shallower systems, the Radion XR15 G6 Pro and Radion XR15 G6 Blue scale the same core technology down to a more compact footprint suited to nano and mid-size tanks. The Pro and Blue naming across both sizes generally reflects a difference in spectrum tuning and channel mix rather than raw output, so the right choice comes down to which spectrum profile suits your coral mix rather than tank size alone. The XR30 G6 Blue and both XR15 G6 models are still moving through listing; we’ll link each as it publishes rather than guess at a URL that may not match the final listing.
Optics and spectrum shaping
A Diffuser for Radion fixtures softens and spreads the point-source light output, reducing the “disco ball” shimmer and hot-spotting that can otherwise show up under a Radion, particularly useful in shallower tanks where the light source sits closer to the water surface. On the opposite end, High Intensity Lens Kits are available for both the XR30 and XR15 lines, narrowing the beam angle to push more usable light deeper into taller tanks at the cost of a slightly smaller lit footprint per fixture. The XR30 High Intensity Lens Kit is now published at IndieFur; the Diffuser and the XR15 version of the lens kit are still moving through listing.
Mounting systems
EcoTech’s RMS (Radion Mounting System) range covers everything from single-fixture tank mounts to multi-light arm setups. The RMS XR15 G5 & G6 Tank Mount System and RMS XR30 Single Light Tank Mount System clamp directly to the tank rim for a single fixture without needing an overhead hanging point, which matters if you don’t have ceiling or stand access for a hanging kit. For hobbyists running multiple fixtures over one tank, the Multi-Light RMS Arm Kit and RMS Slide for Radion XR15 let you position several lights independently along a shared rail rather than mounting each on its own separate arm. If you’d rather hang lights from above than clamp to the tank, the Radion Single Light Hanging Kit (6ft) and RMS Rail Hanging Kit XR717 cover single-fixture and rail-based multi-fixture hanging setups respectively. The RMS XR15 G5 & G6 Tank Mount System and Multi-Light RMS Arm Kit are now published at IndieFur; the RMS XR30 Tank Mount, RMS Slide and both hanging kits are still moving through listing.
Bridging to Neptune Apex control
If you’re already running or planning a Neptune Apex controller, the Neptune MXM Mobius Wireless Control Module is worth knowing about specifically because it’s a cross-brand bridge rather than an EcoTech product: it lets an Apex system communicate with EcoTech’s ecosystem (Radion lighting and VorTech-family pumps) over EcoTech’s own wireless protocol, so lighting schedules and pump behavior can respond to Apex sensor data rather than running as two separate, uncoordinated systems. This module is still moving through listing without a live product page yet; see our Neptune Systems guide for the rest of the Apex ecosystem it connects to.
What’s actually available today
Four items from this lineup are now published and available to order at IndieFur, all on backorder: the Radion XR30 G6 Pro, the XR30 High Intensity Lens Kit, the RMS XR15 Tank Mount System, and the Multi-Light RMS Arm Kit, all linked above. The rest of the Radion fixtures, optics, and mounting hardware detailed above are still being finalized rather than live, purchasable pages. Check the linked pages directly for current status, or reach out if you want to confirm availability on a specific model before it’s formally listed.

Planning a Radion purchase
If you’re mapping out a Radion-based lighting upgrade, decide fixture size and mounting style together rather than in sequence. A rail-based multi-light arm kit needs different tank clearance than a single hanging kit, so it’s easier to plan both from the start than to retrofit a mounting change after a fixture is already installed. Given that most of this lineup is still moving through final listing, treat the specifics here as a planning reference and confirm current availability before finalizing a purchase.
