I use cfls but lol my Veg will kick ass but flowering your mh might be a little better as ive got,
2 x 85w big Cfls (5200) lumens each 1 x 30w little Cfl (2000) lumens
3 x F tubes (20-30w)equal to about (6000) lumens
so i got about a total 18,400 lumens
Where as you have got a Mh and a 400w one has about 32000 lumens
