Im finally ready to change over from my M/H to Radions. I have a 120 and was thinking to get 2 fixtures. Since the price dropped its a no brainer. My Q is does the 2nd gen makes a big difference with the TIR lenses? or just go with 1st gen? My tank has about 50-60% SPS the rest softies.
While I have not done or seen the TIR lens upgrade myself, I have heard nothing but good things about it. Anything that will help eliminate color banding is worth a shot IMO. I'll be getting the upgrade kit soon.
