A bit of both, my only concern with your original post was it had too broad a brush, painting all Chinese LED's as junk. I don't disagree that there is junk, have a couple in my basement that won't see any action, except maybe cool lighting in my music room when it's finished
My son has one of my original purchases which he's using for vegging while he builds his new room, it does ok in veg but sucked big time in flowering. The current LG grow though is rock'n, continues to put fat on the nugs, no sign of slowing down.
