I just switched my mh out 2x 250w 2x110w vho was just got tired of all the heat it was putting in my room and tank so I now have 2x 110w vho super actinic witch are the best 420 nm you can get and 4x t5's one purple + one blue+ one lagoon blue and one coral+ and couldn't be happier same growth if not better and for sure better color ! Also switch out my frag tank 400w mh for the ai hydra led with controller and love that two also love my new lower electric bill. Only reason why I say this is I've been die hard mh for years and now with all the new lighting options I think they might be at the end of there road my opinion at least
