lights for frags

[morph]

Hi there I have six large metal halide lights 400w in three 38in x 18in enclosures with tempered glass shields.the ballasts are on each end so the actual lighting area is 24in they also have 24in polished aluminum reflectors.As is they are to large and heavy for aquariums the parts however are great for diy lights .Iwould like to swap for polyps ,mushrooms,or leathers anything i dont have that will do well under 3 w atts per gal of cmp flour and no flour.
