Putting together a smallish grow setup. Probably a 4x4 tent with 1-4 plants and lowish ceilings.

Looking at the NextLight Mega, Pacific CX420, and Timber Cree and Vero frameworks. Thoughts on Pacific vs Cree? It seem some YouTube videos showing smaller COBs (eg Pacific CXB400) working better than the flat panel MCOBS (NextLight Mega). Technically the NextLight should be better - do you think it may be grow height? The large size of the NextLight looks awkward and fragile yet stunning. I want something durable, powerful, and easy to move. A COB array may be more expandable, right? Is CO2 possible with any of these lights? Am I really that much better going DIY cobs? Any experience with actively cooled units like Johnson? Passive cooling seems more elegant/robust. Thoughts?

Northern Growlights/Horticultural Lighting Group's Quantum Board is an interesting developement. capable of 200L/w and only about $100 each with a heatsink, not including a driver

QB304 Quantum Boards
High efficiency boards designed for DIY projects. Can be powered from 10 to 150 watts. Ideal for use in grow tents or grow area with reflective walls and grow spaces with limited height. No TIM is required.

Specifications
  • 304pcs Samsung 561C top bin Diodes
  • Connectors rated 300V 9A
  • Estimated LER 321.60 lm/W
  • Estimated QER 4.86 µmol/J
  • Dimensions 6.833" x 11.25
Voltage* (Vf dc) Current (mA) Watts at Board (Watts)
Lm/W at Board** (40C)

101.8 250 25.45 200
103.1 350 35.70 192.5
105.1 500 52.55 184.3
106.9 700 74.83 176.8
109.9 1050 115.39 166.7
112.6 1400 157.64 158.7
* Voltage calculated using sample board. Voltage may be +/- 4% for boards in different batches.

DIY is cheaper.

Northern growlights and tastyled also make good COB panels.

Pacific uses Crees.

I find Nextlight Mega to be overpriced.

CO2 is possible.

The current generation of Citizen (CLU) COBs and Vero gen 7 are more efficient than the CXB cobs from Cree.

2 Photon 180CLU 1825 from Northern growlights are the same price as one Pacific CX420, but more efficient with a very similar power draw.

Tastyled is a little more expensive per watt, but is really good too.

They're all good lights that will grow a lot of weed.

We (Horticulture Lighting Group) will build you a custom panel using the quantum boards if you prefer. You won't beat the performance or price of this option. I recommend 4 boards on 2 240h drivers. Total power draw is 590-600 watts and will put out more light than any light you mentioned above.

What's the price on this? Where are your numbers to back this up? Links to completed grows and proven results? What certifications does this light come with?

Easy on the recommendation. I need 4 more if I like the 4 I have. I don't want them to run out!
