HPS 400w

I'm considering swapping out my current light setup: single 100w MH and twin 150w CFLs for a single 400w hps. Anyone got some info on a site/source and brand that's good quality but doesn't break the budget? Even a good price range will be fine.


Edit: Will be using it in a grow text that measures 2x4x6

I've grown with a 400w in a 2x4x6 and it sucks. It's better in a 3'x3', with the 2x4 you get heat in the center if you try to get good light to the ends or you get loose buds on the ends if you keep it good for the center. I only grew iwth HPS for years but last year I went with COBs and have only harvested once but I can see the potential, have you ever thought about going with COBs?

i get 3x3 tent i used cob led only 340 watts
