I'm right around 5 years for my LED "chinese black box" 165 watt light. 29 gallon (30 inches long) mixed reef. 3 montis and the rest are softies like zoas, mushroms, leather corals. I'm not trying to spend 400 $ plus if i dont have to since my tank has done fine for some time now. I am open to recommendations as i see a lot of people like the AI primes but at 60 watts per light 2 of those would be less watts than i have now and i felt like 3 is going to be over my price range. viparspectra is another ive seen around for a while. Anyone with a similar sized tank thats mixed reef with a preference? TIA!
