best 600 hps bulb

ok so im going to buy a nextgen digital ballast so looking into bulbs i want to get one with a enhacned spectrum so whats the best bulb for the cheapiest price all imput is appricaited seen horilux for 85 looking for a great bulb for closer to 65

Hortilux is the standard. Spend less on the ballast and more on the bulb ehh

well the differnce between a new magnetic and a new digi is only like 20 bucks so id rather have a digi plus the nextgen can run 400 or 600 watters hps or mh so seems like a good investment i buy 1 600 bulb it pops i can put in a 400 until i get aother 600
