Best bulb for flower (hps,cmh,mh)

Im looking to upgrade my 400 hps bulb right now it gets 46,000 lumens and its like a year old. im looking to get a better bulb than i had last time..any1 know of flowering bulb for a 400w HPS ballast tht does better than 46,000 lumens at 2100k

super hps from hortilux 400w is 55,000 lumens and the SUPER means it has an added blue spectrum to it

Nice thanks man, some blue will def help cause i do 2 week CFL veg then put it under my HPS for 2 more weeks before flower..+rep on tht
