• HEI (Hemispherical Edge Illumination) lens for even, shimmer-reduced spread rather than a single hot spot
• Full-spectrum white LED array (warm and cool white dominant) with red, green, blue and lime accent channels for plant colour and growth
• Wider body than the XR15, giving broader single-fixture coverage over standard tank widths
• Bluetooth control via EcoTech's Mobius app, no separate WiFi bridge required
• Independent moonlight channel for a dimmed night-time setting
• Compatible with EcoTech's rail and arm mounting hardware for single or multi-fixture setups

We could not find an EcoTech-published PAR or PPFD chart for this specific freshwater spectrum tune on the G5 platform. EcoTech publishes PAR data for its Blue and Pro (reef) G5 spectrums, but that doesn't carry over to the Freshwater tune, which uses a different LED mix. We haven't found a reliable independent PAR chart for the freshwater G5 units either, so rather than estimate we're flagging it honestly: if PAR at depth matters for your plant selection, measure it in your own tank once installed, or get in touch before you buy.

EcoTech's general mounting guidance across the G5 range is roughly 18cm (7in) above the waterline or tank rim. This is a general G5 recommendation rather than a figure published specifically for the freshwater spectrum.

Suitable for

Freshwater and planted community aquariums, wider or longer tanks where one fixture needs to cover the full width, and aquascapes prioritising plant growth and a natural daylight look.

Not suitable for

This is not a reef or coral spectrum. It doesn't produce the blue-shifted output or PAR profile that SPS or LPS coral keeping calls for. If you're lighting a reef tank, EcoTech's current equivalent is the Gen6 Radion Blue or Pro, built specifically for coral.

• Radion Rail Kit (sold separately) - mounts one or more fixtures on a rail across an open-top or rimless tank
• EcoTech Single Arm RMS or Multi-Light RMS mounting arm (sold separately) - clamp-on options if you'd rather not use a rail
• Radion XR15 Gen5 Freshwater - if you're lighting a smaller tank or want two smaller fixtures instead of one large one

Do I need one XR30 or two XR15s for my tank?

It depends on tank width and how even you want coverage to be. One XR30 covers up to roughly 91cm x 76cm at maximum spread (76cm x 61cm recommended for full coverage), which suits a standard-width tank with one fixture. Two XR15s over a long tank can give more even coverage across the full length but means pairing and running two fixtures instead of one.

Is this the same light as your reef Radion models?

Same Gen5 hardware platform and control system, different spectrum. This Freshwater tune runs full-spectrum white LEDs (warm and cool white dominant) built for plant growth and a natural daylight look, with RGB accents, rather than the blue-shifted spectrum of the Blue and Pro reef models. For a reef tank, look at EcoTech's Gen6 Blue or Pro Radion instead.

Do I need a ReefLink or EcoSmart Live to run this?

No. This is a G5 fixture, so it connects directly over Bluetooth via EcoTech's Mobius app. Unlike earlier Radion generations, it doesn't need a ReefLink WiFi bridge or the older EcoSmart Live system to get going.

Will this grow coral colour, or is it just for plants?

It's built for freshwater and planted tanks, not coral. Coral colour and growth respond to a spectrum and light output this fixture isn't tuned for. EcoTech's current reef-specific line is the Gen6 Blue or Pro Radion.

Can I dim it or run a day and night cycle?

Yes. Control is through the Mobius app over Bluetooth, which lets you set light levels and schedules, and the fixture has an independent moonlight channel for a dimmed overnight setting.
