Degenbao light...ballast help

[Chaloupa]

I got a Degenbao light from Hidden Reef a year ago...I need to replace my bulbs and am having a tough time finding 2x400W that I like...my question is; does ANYONE own one of these...and do you know what type of ballast they come with, as it is internal? The MH that came with it were a 20K and really really blue when combined with the T5's...... Would I buy this light again?? NO...given another chance I wouldn't, but bought what was offered and recommended...

If you can help...please let me know...I tried to put in a pair of Venture 14K but they don't fit in the fixture...so now am leaning towards the aquaconnect bulbs...but don't know the ballast type...and having returned many bulbs now...don't want to try again!
