Uhhh, if by "Lumen ma" you mean "Lumenmax" then those are reflector pendants that don't have anything to do with wattage.

MH setups basically have 3 separate components: ballast, bulb, reflector. A "400W" MH setup uses a 400W ballast driving a 400W bulb underneath a reflector (no wattage).

I believe your trouble is that you won't find any pre-packaged 400w MH systems like Coralife's Aqualights, for example. That's because the market for 400w systems is quite small. The most the vast majority of reefers require is 250w. So you have to put together your own a la carte from outfits like Hamilton and PFO. You can do this at pretty much any dedicated SW LFS like J&L:
