Ecotech Radion

[Aqua-Digital]

I never measured it but visually there is a difference, the radion puts out more depth of light into the tank.

My green slimer that is at least 18" down now has full polyp extension where as before it was very half hearted.

The other noticeable point is that I always got a disco ball effect with the Ai's on the sand bed, and with the Radion this is non existant even with the different colour LED's

I went from Ai to pac sun and then onto Radion, in less than a week there is a massive improvement in my SPS colouration.

Ai served me well, but times move on and I do believe radion now has the leading edge here. But as with all products head to head, beauty is in the eye of the beholder
