I'd go with the 750s . I have the phantom 6/750 and it's a beast . Not many places carry those bulbs at a reasonable price though.Not the raptors but the ones like them from hydrofarm. The magnum xxl 8”. Gonna be upgrading soon tho. My pole barn is gonna start being built in 2 months. Haven’t decided if I’m going LEDs or Gavita 750s
