i been sarching for light's for my 90 gal.for a while bought leds twice and returned them because they just wasn't giving me what i wanted. so andyv20004 told me to check out fathom and after several attempts to get in touch with them i almost gave up on fathom,i'm glad i didn't they called me and 2 day's later they were at my home installing my light's.yeah that's right they came to my house and did the insallation in a canopy that was not easy. they tried different optic's to make sure i got the best spread and depth for my tank and they would not leave until i was completely satisfied i was extremely happy.fathom are true professionals!!! so keep your ai and radions only fathom for me.
