Welcome back! Im in the same boat with you, an old salt back after 12 years. Get ready because technology has changed the lighting game. Like you i knew the world of MH and T5HO, got great shimmer from them. I just put a Kessil a80 tuna blue on a nano tank and the shimmer is the same as the old MH but the A80 is only 15 watts. Crazy right!? Anywho, I look forward to seeing your future tank!
