@dbrn32 if this next part sounds pre-typed, it is lol. I started putting my thoughts together yesterday and here is what my collection of brain cells produced:
"Let me give the long winded version for my opener, and I’ll trim down any future answers lol. I’m looking for a new light for my 4x4 grow tent. I’m currently working with a Viparspectra 700w (only pull 326w from the wall). The back story on this light is at time of purchase in 2017, the website claimed it would work with a 4x4 but they have since slashed that number and updated their stat page. (I only have a few screenshots to back my claim but it makes no difference at this point) To make up some difference with the VS700W , I recently bought a light mover. Together these are not doing it. I’m ready to put down some money and I’d rather built it myself.
Thus far, I made it to post 1200 of your 5,000 post thread, watched LED Gardeners build videos, and watched many of Growmau5’s videos and most of the 2.5 hour video he posted and while I have absorbed a ton, I just feel overwhelmed. I understand many of the numbers separately, PAR, temperature color, most of the concepts behind the driver its milliamps and such but I don’t know how to formulate my own build. So I’m hoping you can help.
Here are my goals:
-Cover a 4x4 tent from veg to flower: 3500k? CRI 90?
-Open to COB, strips or Quantum boards…the more I catch up on the forum posts, the more I see QBs
-Preferably a single fixture with a single driver
-Dimmable would be nice. I’m capable of soldering resistor.
-I’ll spend more on efficiency but I need low heat as it will be in a tent. (I have an exhaust fan and small desk fan in the tent)
-Not counting petty items: cable, tape, angle iron, wagos…I think I’m willing to put out about $550-ish on the light, heatsinks, driver.
I looked at a few HLG kits and I think I really like 320Watt XW Quantum Board LED Kit v2. This says it’s for 3.5x3.5’ max flower but I have a light mover. Could I use this in my 4x4?
Then I went and looked at the HLG 320 Watt XL Quantum Board LED Kit V2…and I thought…more boards, more diodes, more expensive, must be better coverage. Nope. The description compared to the previous light suggests using two. Now I’m confused.
I looked at the HLG-550 Quantum Board LED , too expensive…but can’t I build my own for cheaper? @MAXHeadRoom built a really good replica that I just found moments ago. If that would work in a 4x4, I’d like that. As long as I have the right boards and driver(s), I can get angled aluminum and make a frame
…before I get all gushy about QBs, is this the route to go?
