Okay. Last question as I'm literally about to order the timber. Should I go with the 3vl or the 4vl? Only 100 dollar difference. I have a 2x4 tent. Do I need the extra light the 4vl has?Full spectrum is kind of a confusing marketing term with no 100% agreed upon definition. The general idea is that it should cover all the wavelengths that are useful to growing marijuana but that is where a lot of the debate is. Every light has a spectrum, technically the more white the more full the spectrum as pure white light reflects all wavelengths and absorbs none, this would not be practical for growing though. All of the lights you posted are going to be pretty similar in spectrum when comparing the same color temperature, I don't think one will be better than the other in that regard. I would pick either a 3000k or 3500k.
The Timber 3vl is a better watt/dollar value than the Chilled Logic unit but the 5 cree cob cxb3590 is slightly better value than the timber if you upgrade to the more powerful driver. Personally I think the Timber looks like it is built a little better than the other two but I only own the Timber so I may be biased. Timber also appears to be the only option with a warranty (3yrs).

Here’s my thoughts regarding the very capable Timber fixture pictured, the 3 cob 3VL. They’re driving those individual cobs at over 100 watts each, those massive heat dispersing fins are there for something, it’s to dissipate the heat. Question, how hot do you think your tent is going to get with that going on inside? When your dividing that wattage over more fixtures, you should be getting to a sweet spot as far as the quotient between light and heat created, more cobs, less total heat. Ask what the expected heat rise will be in that modest sized tent of yours? I know that I can keep my tent maximum under 85º (12 cob, 600 true watts) with only minimal exhaust, That should be a concern, I read somewhere that at 100 watts per cob, half of that power was being given off as heat, something certainly to consider...
Hmm. Well this is the tent I have for now. Right now I have to keep a small heater in my tent just to keep it between 70 and 75 degrees Fahrenheit. I'm new to all this so not exactly sure how to answer your question or how I would know how to calculate the heat.Here’s my thoughts regarding the very capable Timber fixture pictured, the 3 cob 3VL.

Is there a website I can go to to build something like you recommend...sorry if that's a boob question....im still learning.You can do a strip build with 8 2' strips, 4 bars, 1 320 watt driver & all needed parts for basically $400. $216 for the strips with Samsung LM316c Top Bin diodes (100 per strip I believe, if not its 96 per strip) & the newer cree 660nm red diodes (4 per strip) , $85-$90 for the driver. like $10 per bar so $40 for 4 bars, 2' of t channel $15, 4 t bolts, some solid core wire, 2 wago connectors, 1 waterproof AC wire connector $5 & 1 power cord $5-$7
That light will not run warm or hot, it will cover a 2x4 tent better (more evenly) than anything else that you can buy, it uses the best of the very top BIN best diodes, diodes should last 10 years at that power in that set up at 40 watts per 2' strip (max is like 60-70 watts so they are being run pretty easy at 40 watts thus the lack of heat they would produce because as the wattage goes up the temps go way up because diodes nor cobs run as efficiently at higher wattages, lots of power is lost as heat & the hotter a diode or cob gets the less efficient it becomes. Running diodes & or cobs at lower power is the only way to do it! It costs more to have more diodes running at lower power per diode but its the very best way to do it!
So you are saying that all the light manufacturers agree on the definition of full spectrum and all "full spectrum" lights are pure white light? I don't think this is the case, they use it as more of a marketing term. I was pretty clear that true full spectrum reflects all wavelengths (colors are wavelengths) and absorbs none so I don't know what you think I'm debating or clueless about.anyone saying there is a debate on what full spectrum is.. is clueless.. because science has always known. full spectrum is white light there is no debate... white light is only achieved by combining all colors together, its the exact opposite of paint or printing where if you combine all colors you get black. There is no debating this science, no way
The 3vl will have plenty of power and would be great for a 4x2. While I don't agree with completely with @Dan789 about 100w cobs wasting 50% of there energy on heat when at 100%, it is true that the 4 cob setup ran on lower power (it has a dimmer) can perform as well with better light spread and less heat output than the 3 cob at full power. In the 4x2 you would probably never have to run the 4vl at full power which would also dramatically extend the lifespan of the driver and cobs. If you can afford the 4vl get it, but know that the 3vl is also up to your needs. Also, fwiw my Timbers dont get nearly as hot as my hlg lights, I think because of the space between each cob versus a bunch of panels on the same heatsink. The design of the heatsinks on the Timber are to pull the heat up and away from the light and canopy and they do a pretty good job, even at full power they are only warm and I can comfortably put my hand as close as a couple inches away from the leds.Okay.

Go ahead and research what @maximusluminous suggested, you can design and build a nice light for yourself but I don't think you will save much if any money going that route over Timber or HLG for a light with comparable performance, you'll have to have some basic to intermediate electrical skills, and you will most likely be giving up any kind of warranty or support.
The light strips can offer superior coverage to some lights with the right layout but the difference would be negligible in a 4x2 tent compared with the lights I recommended.I don't say you were debating it, but many light companies are full of crap!
I have HLG & Rapid LED/Chilled set ups.. promise you I will build a 4 bar 320 watt set up next & then another to have a 4x4 640 watt set up in total & It wont be but maybe $10 cheaper per 320 watts than an HLG Rspec 320xl set up would cost if you just buy the heatsink & 3 boards from HLG & source the rest of the parts elsewhere or else pay $480+ for their kit which would run you a good $55-60 more than the strip build would cost ya. I was able to build the hlg 320xl set up for like $410-$415 by only buying the heatsink & 3 boards as a combo package that hlg offers for $289 & buy the driver & misc other parts elsewhere. I didn't pay their $480+ they want for the whole kit. Thing is a strip build kills the coverage by any LED makers that do not make bar lights, there is no other way possible to cover a canopy more evenly that with strips so that alone makes it better than HLG & any cob nonsense let alone its slightly cheaper than an HLG build... it a win win & its not even a real contest!
