600 watt hps Bulb Question

just wondering what brand of hps bulbs everyone is using with their digital ballast? i'm not sure what brand to buy after i heard most brands are not compatiable with digital ballasts...i have a 600 watt quantum ballast, thanks any help or suggestions welcome..

hortilux are the best ones and what i use..u can get a cheaper one though, it's up to you..the times i bought my lights i had bought the lights that came with a bulb..usually u can use those for over a year to, there decent/good bulbs.

That pretty much says it all.

I'm gonna get a digilux next time.
