For someone looking for a good budget light with great spec this looks like a real treat right now with blackfriday discount and what looks like another 36$ coupon.
Problem is that the spectrum they show doesnt seem to match up with the diodes stated. Silly website which cuts off spectrum without featuring the main draw; sub 400nm UV. I very rarely rec budget lights, but this looks amazing if the diode count in the pics is true. The spectrum showed seems more like its based on 5000k rather than 4000k.

OP: if you can confirm the diode count with vivosun, or have a card which lets you just send it back if its not as specified i would look no further, get your card out and treat yourself to a better upgrade:
- Similar price per watt (youll probably wont need all the watts but youll love having them later) - and new instead of second hand.
- better spread with bars and likely better heatsinking than a board light.
- UV will change the way your buds taste and smell a great deal to the better.
@HydroKid239 that is a fantastic find imo, as long as somebody could bone out whats right: diode count or spectrum. But even if it was the spectrum snd not the diode count id still say its quite good. GREAT WORK SHARING! Very few times i diverge from my DIY or Die-stance but this looks like a real good deal.
