I love the Hortibloom fixtures. I have harvested steadily since July (I rotate plants around from a 4k section of boards to finish in the 3k section of cobs)
I run 2 of the Lumba B4 in 3k with various other lighting.
They work great. They daisy chain. Nice dial adjust ability. Much prettier than if i built it myself and i dont slice my head on it when i hit it (It goes BONK!)
I really liked the 180 dollar price. The 240 price not so much.
