My radion Gen 3 has lost intensity since I've gotten it. I was running it at 18% intensity for 2 years or so and it was producing 90 par on the sand bed. I've had to crank it up to 30% recently to produce the same par.
I'm running mine at 90%. Was at 60% but color and growth were off. I'm adding 4 t5s soon. I already bought the setup just want to get the radions working on the same page b4 adding them...
