I've been flowering for the last 14 years with an analogue 600 watt hps. 8 years horizontally and the last 6 vertically. It still works great but I've always had venting problems due to a long exhaust run with several elbows and squeezed duct because of a structural beam. I've decided to retire the hps and give quantum boards a try.
I bought a 480 watt set up from Shen Zhen Bava. It consists of 4 qb288's with 561C diodes, Meanwell driver, dimmer and color temp of 3500K. It cost $502CAN including shipping and brokerage which is very cheap compared to locally available units. I'm keeping my fingers crossed it doesn't crap out on me and I make no claims about it's reliability or efficiency. On the surface though, it seems to have the same specs as the HLG 550 v2.
