They look great.
How much would it cost me to build 700 watts of cob lights. Also how much would it heat up a room

Much less than it would cost for a premade fixture. Ask @CobKitsThey look great.

There you go mate! It's really worth to invest in those lights and delivery is super fast!I believe they can be built in that configuration. Are you in the UK? If so, @Gimmetheweeda post the link to the model you ordered. Or @CobKits do you ship to UK?

DIY can get you close to 1$/watt. Strips and boards are usually the lowest cost with cob next, depending on how many arrays you want to run.They look great.

Yes strips are better than Cob. Better lumen/photon per price. Better lumen/photon per wall watt. No heatsinks required with EB Gen2. Better uniformity.Are strips better then cob?
The description says they're using QB288s (they also use the term "Quantum Boards"), but I don't see HLG's branding stamped on the boards in the picture, and the diodes are in an unbroken line from one end of the board to the other, like a QB304. I don't have a problem with another vendor selling PCBs, but if Timber is using non-HLG LM561C boards (that are designed to look like QBs), they certainly shouldn't call them QBs. That's HLG's brand-name. Also noteworthy is the fact that they're S5 bin, which further persuades me that these aren't actually QBs.

Pretty sure PPFD/Intensity, COB > EB watt for watt. Maybe more dispersion, but less intensity.Yes strips are better than Cob. Better lumen/photon per price. Better lumen/photon per wall watt. No heatsinks required with EB Gen2. Better uniformity.
Wanted to thank you for the Veteran’s Discount, by the way. Really loving the 2VL. Are you using the 90 CRI or 80 CRI? I really like the passive cooling. No fan noise! If I were to buy a Citi kit, could you give me or sell me at a reduced rate, the pieces to attach them to the frame of the 2VL?
~$550They look great.

I was going to say ~$500, but wasn’t sure.~$550
it would heat up the room as much as 700W of HIDs, 700W of computers, 700W of heaters, toasters, etc.
Buying an AC unit just increases your electricity cost. It will never really pay for itself. OTOH, a good quality LED fixture will use about 30% less power, essentially paying for itself over time while lowering your heat issues.As of now I am running 1 1k in my 4x8 tent (half for flower other half work space since I dropped a patient and only can have 12 plants) I'm trying to max my yields with what I have. However my tent gets hot and have been looking into a portable a.c. to put in there. However would it be a better option to spend 500 on building a led light to replace my 1k hps or should I keep my current light and buy the a.c. unit?
You can DIY a 600W LED strip fixture using Samsung F-strips or Bridgelux EB strips for under $400.... That will just about replace the 1kW HPS.As of now I am running 1 1k in my 4x8 tent (half for flower other half work space since I dropped a patient and only can have 12 plants) I'm trying to max my yields with what I have.

http://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/The 300 watt cree 6 cob kit looks appealing as well seems it would have better coverage or no? It's also 100 bucks more. And for 20 less watts
