Ecotech Marine XR30 Diffuser G1-G4 (XR611)

The diffuser surface helps to spread out the light coming from the HEI lenses even more, while the white faceplate helps to reflect even more light down into the tank.

The biggest advantage to using the Radion LED diffuser is to spread out the light even more, soften hard shadows, increase colour mixing, and especially to decrease the disco-ball effect that occurs in some unevenly lit areas of the aquarium.
