I've used both the Radions and the aurora. I can say my LPS respond better and look better under the aurora. I've got the 24" fixture over my current tank. I've come to really like the look of the tank itself under a hybrid. I've got a new tank on it's way that will be using two existing XR15's I have and the aquatic life hybrid fixture. I'd really like to put an aurora over it but talk about sticker shock for a larger fixture.
