The lights are only 6mths old. I bought them for my 220g used at 5hrs daily on RKE schedule, since then had an abrupt move and had to downsize to 93g cube. Looking for LED fixtures for cube. Interested in two AI 26 or 52 fixtures, Radions G3 & up, also ATI 24" will do. I am in PA, but can ship on your dime. Thanks.
