Toss the Disco Ball—This Light Diffuser Reduces Shimmer Without Sacrificing Sparkle
Shimmer is great on a gold dress, not in your reef tank. The Radion XR30 Diffuser Upgrade flattens excessive shimmer so it resembles natural sunlight—not a strobe light at Coachella. Fish look calmer, corals color up evenly, and your tank feels more like a slice of the ocean.
Better Spectrum Blending = Happier, Healthier Corals
LED lights are great, but without a diffuser, they shoot down in narrow beams—like little lasers. The XR30 Diffuser blends the output into a cohesive wash of light, giving your corals what they actually need: spectrum balance, not spotlight drama.
Aquarists running full-intensity setups might notice a slight PAR drop. But in most tanks, the even spread makes up for it—especially in corners and low spots.
Smart Mounting With a Sleek Look
EcoTech didn’t just throw magnets in and call it a day. This diffuser clicks into place with strong magnetic mounts, keeping the profile clean and modern. It installs in seconds and removes just as fast for cleaning.
