Hydra 52 quick question

[alindell21]

I am looking at getting two hydra 52's and a Neptune awm for a good price. The seller says they have been used about 2 years and have been run 7 hours a day with never going over 80% on the leds. He says they are in good shape. So my question is if I run them at similar power output and take good care of them and run them about 10 hours a day, how long do you think they will last to effective in a reef tank so what is the life expectancy or how long would you use them if you got these. I am looking for ball park figures or if you can provide specific knowledge. Thanks

Theoretically lifespan of leds is like 50,000 hours so actual led lifespan probably not an issue it's other components. A well taken care of piece of equipment shouldn't be an issue with a quality company of ai. If it truly is a good price for a 2 yo fixture id go for it

what would you pay for them?

 

[alindell21]

so under my simple calculations there should be maybe 4 years left of life for me.

 

[alindell21]

actually nevermind I forgot to compensate for his hours of life so he has 7 hours time/a day for 730 days= 5000 hours of life of the light so I should have 45k hours left but conservatively probably 40k hours left

I have the same setup on my 90. I would guess somewhere around 600 or 700.

so I bought it, i t was$700 shipped for both lights and the neptune awm plus some extra mounting stuff. I think that is a decent price for everything thinking that the lights will still last over half a decade for me given 40k hours left running 10 hours a day.
