Radion RMS Gen5 Adapter Kit
Puts a current fixture on the rail you already own. The Radion RMS Gen5 Adapter Kit is a small upgrade part: an X-bracket and an end cap adapter that let a Radion G5 or G6 fixture sit on an RMS mount originally built for a G4. It exists for one situation only – you are replacing an older Radion and want to keep the mounting hardware already over your tank.
Do you actually need this?
Most people buying a new mount do not. Read this before you add it to your order.
| Your situation | Do you need this kit? |
|---|---|
| Buying a new Radion RMS Tank Mount today | No. The current kit already includes the G5/G6 X-bracket. |
| Swapping a G4 Radion for a G5 or G6 on an RMS you already own | Yes. The older G4 hardware will not accept the new fixture. |
| Buying current-production RMS slides for a multi-light rail | No. Current slides already fit G5 and G6. |
| Reusing old G4-era slides on a multi-light rail with a new fixture | Yes, one kit per fixture. |
| Going from a G5 to a G6 | No. The same bracket carries both. |
Key features
- Covers G5 and G6 alike – there is no separate G6 adapter. This one kit handles both current generations.
- Rotating X-bracket – mounts the fixture parallel or perpendicular to the rail, so you can turn the light square to the tank.
- Sized to the fixture – XR704 for the XR15, XR705 for the XR30. They are not interchangeable.
- Keeps the existing arm – you reuse the rail, arm and clamp already on the tank, so nothing has to come off the glass.
What's in the box
- One X-bracket, sized to the fixture (XR15 or XR30)
- One G5 end cap adapter
- Two screws
- Instruction sheet
The two screws fasten the end cap adapter. They are not for fixing the X-bracket to the light – a common misreading that leads people to look for missing hardware.
Not included
- The Radion LED fixture
- The RMS arm, rail, clamp, track or slides
- Any part of a complete mount – this is an upgrade part, not a mounting system

Suitable for, and not suitable for
Suitable for:
- Owners upgrading a G4 Radion to a G5 or G6 who want to keep their existing RMS
- Multi-light rails running older slides, at one kit per fixture
- Anyone who bought an RMS mount before the Gen5 fixtures were released
Not suitable for:
- Use with a newly purchased RMS Tank Mount, which needs no adapter
- Mixing sizes – XR704 will not adapt an XR30, and XR705 will not adapt an XR15
- Mounting a fixture on its own – there is no arm or clamp in this box
Goes well with
- Radion XR15 Gen6 Blue – the fixture most often going onto an older XR15 mount.
- Radion XR30 Gen6 Blue – the XR30 equivalent, which needs the XR705 kit.
- Radion RMS Tank Mount – the alternative if your old hardware is worn and you would rather start fresh.

Freight: standard parcel. No oversize, dangerous goods or cold chain handling applies.
Common questions
I just bought a new RMS tank mount. Do I need this too?
No. Current-production RMS Tank Mount kits ship with the G5/G6 X-bracket fitted, so a G5 or G6 Radion attaches without an adapter. This kit is only for RMS hardware bought before the Gen5 fixtures existed.
Is there a separate adapter for G6 fixtures?
No. EcoTech supply one adapter kit that covers both G5 and G6 fixtures, which is why the retail name lists them together. A G6 light uses the same bracket as a G5.
Why will my old mount not take the new light?
The mounting interface changed at Gen5. The G4-era X-bracket and slides do not match the end cap on a G5 or G6 fixture, so the adapter replaces that interface rather than modifying the light.
Will the XR15 kit adapt an XR30?
No. XR704 is for the XR15 and XR705 is for the XR30, and the brackets are physically different. Order the kit that matches the fixture, not the one that matches your rail.
What are the two screws for?
They fasten the end cap adapter. They are not intended to fix the X-bracket to the light fixture, so if you are hunting for screws to mount the bracket itself, you are not missing any parts.
I run three Radions on one rail. How many kits do I need?
One kit per fixture, so three. Each kit contains a single X-bracket and a single end cap adapter, and each light needs its own.
