Here is a side by side the vegas are on the left g1 radions w/o tir lenses on the right.
the vegas are at %100 (no controller at the time) and the radions are at aprox %75 (still ramping up at the time)
I will add I ran the tank like this for a couple months and there was no noticable growth difference but the vegas ran at %100 all day while the Radions ran a custom profile.
****I'd also like to add my tank is much nicer and fuller now lol****
