when do you all replace your kessil 360x?

[FishPersonFL]

I mean to replace due to spectrum shift or par reduction, not light failure.
Do you just replace them after max 7 years? Do you go by coral growth? I dont have a par meter (cant find it). But even if so, I dont know the spectrum, and when it will be less than 'good.

Edit: I forogt kessil replaced mine in 2022, so I shoudl be 'good' still. When they replace them I'm pretty sure they were new.

Thanks!

I have had tons of kessil lights over the years. I have one 360 non-X that has been running since 2012 that is still going. I have also replaced at least three A360s/360Xes over the years. I get 5-7 years out of them, and normally they just stop turning on at that point. The lights that last the longest are those the farthest off the water. Yes, the lights are water-resistant, but saltwater is hard on everything. If you can elevate the lights and use a narrow lens then it will likely make the lights last longer.

May I ask how often you do maintenance on the lights?
