Catalyzes the reduction of fatty acyl-CoA to fatty alcohols (PubMed:19062129, PubMed:24005667). Catalyzes specifically the formation of C16:0 fatty alcohol (PubMed:24005667). a long-chain fatty acyl-CoA + 2 H(+) + 2 NADPH = a long-chain primary fatty alcohol + CoA + 2 NADP(+) Belongs to the fatty acyl-CoA reductase family. Extended C-terminus.
