Me? I just use any good 100 watt led (actual pull from the wall, typically called a manufacturers "1000" ) for veg, times however much space is needed to cover. On the cheap, Phlizon has a 1000 model (about 100 watts) on sale at amazon for 79 bucks. Samsung 301 leds and the good red ones. Mars hydro, spider Farmer HGL all offer these.
I still have nightmares about T5 tubes from the old days. Large, clunky, old dead tubes to deal with, etc. These small panels are the bomb for mother/veg uses.
