depends

if you are using DE bulbs or SE bulbs on the HQI ballast, also depends on what 400's you are comparing to, the only 400 watt set up I have measured ( out of 4) that out preforms my 250's were an iwasaki and they were slightly higher. do a search on my old posts on lighting output or something like that, my test results should still be on here. a few other things you need to answer are, how deep is a 50 gal tank? how much rock you got in it? how much sand.. ect.. personally I don't think a 250 HQI ballast is to much for any tank and depending on the bulb selection (DE or SE) you could get away with 1 in a 3 foot tank, if you use DE's you will need two pretty much.
