Ok, after a bunch of reading .. I now think instead of trying to replace my 4x 54 w t5 in canopy with the Truelumen pro strips.. I may go with the Panorama Pro Marine 48 inch (fusion) along with the 48 in truelumen pro (blue) I already own. Hoping to find it will supprt lps ( acan/scoly) on the sandbed at 18 inches deep. Anybody use these as primary lighting? Please LMK what you guys think!
