AquaticLife T5 HO Light Fixture w/ Lunar LED Assistance

Found a light fixture on my local craigslist for an AquaticLife light fixture. The system is 1.5 years old and new ATI bulbs that was used for two weeks. It also come with legs.

What are some things to look out for to tell if it's a good deal? I read about people having issues with the leds but AquaticLife took care of them.
How long does the ballast last on this kit?
What would you consider a good price for this system?

Oh yeah, it's a 48 Inch 4x54 Watt AquaticLife T5 HO Light Fixture w/ 4 Lunar LEDs.

 

I think T5 ballasts last a good amount of time unless it's a really poor quality fixture.

 

Good find and a quality unit. Ballast should last several more years.

 

Thanks. It definitely exceeded my expectations! The lights are dazzling, LEDs are stunning, and the built in timer is a huge plus. I'm more than satisfied.
