Radion (G1-G4) Diffuser
Individual LED spotlights on the sand bed disappear once the light is properly diffused. This is EcoTech Marine's diffuser lens for the Radion G1 through G4 range, fitting both the XR15 and XR30 fixtures. It spreads and blends the light from the LED cluster into one even wash rather than a grid of hotspots, and softens the shimmer lines bare LEDs can't avoid.
Key features
- Even spread – blends individual LED points into a single, cohesive light source across the tank.
- Reduced shimmer – takes the edge off the "disco-ball" effect of bare LEDs, closer to how sunlight reads underwater.
- Magnetic fit – clips onto a mounting adapter plate, so it lifts straight off for cleaning.
- Fits G1 through G4 – covers the older Radion generations, in XR15 or XR30 size.

Suitable for, and not suitable for
Suitable for softening and evening out light from a G1–G4 Radion. Not designed for G5 or G6 fixtures, which use their own generation-specific diffuser and lens options – check your Radion's generation before ordering.
What's included
One diffuser lens and one mounting adapter plate. The fixture's existing screws are reused to fit the adapter plate; no other hardware is included.
Common questions
Will this dim my light noticeably?
It reduces raw intensity by roughly 20%, which most keepers offset by nudging the fixture's output up slightly in the EcoTech app.
Does it fit my G5 or G6 Radion?
No – this diffuser is built for the G1–G4 lens mount. G5 and G6 fixtures need their own generation-specific diffuser.
Is it hard to clean?
No – the magnetic fit means it lifts off the adapter plate for a wipe-down and clicks straight back on.
