Radion G4 life expectancy

[xabo]

I have 6 Radion G4 Pros. Three are 7 years old and three are 8 years old. Should I anticipate replacing soon? Running the Phoenix 14K spectrum at 100% and getting 350-400 par at lower Third of tank.

That’s pretty decent par for the bottom third, IMO. I’m not an expert, but I’d venture that as long as the lights are physically functioning (turning off/on, fans running, etc) I’d rock em’ until the wheels fall off.
