Right on, man. One thing I want to mention is the setup I'm showing you is a solder free setup. The COB's are poke-in and the thermal pads are easy to apply, no thermal paste involved. Simply purchase 1/8'' aluminum angle bar and use M3 screws to mount the heatsinks to the frame.
Holy shit that is awesome! You rock bro!
Question, what do you use for a reflector? The Timber lights and kits come with the white reflectors for each COB that kind of "direct" the light.
I personally don't, but many others are all for them. if they fit in your budget then definitely add them.
Interesting...do you find you can place the LEDs closer that way?
I keep my Quantum Boards 18'' above the canopy. Here is the PPFD chart at 18'' & 24''
No problem my dude, I'm always glad to help out others when I can. One other thing I need to mention is that for the majority of my grow in my journal I only used two QB 288 boards on one slate 2 heatsink + a 134W Chinese LED. I recently added the second unit to replace the Chinese LED after waiting a few weeks for parts to come back in stock. So the results you are seeing are mainly from one QB288 kit ($325-$350).
Two 260W QB kits would indeed rock a 4x4 tent. The biggest challenge is getting an order placed when they have inventory. Seems like the demand has caused them to run out of stock the same day their inventory comes in.I don’t know much about led lights but, I’ve been watching the Grand master level show and he’s doing a side by side right now using quantum boards vs hps.
The boards he’s using seeme to be killing it. So I’ve really been considereing upgrading to one of HLG’s DIY kits.

I’ve got a 4x4 tent so thinking two of the 260W xl qb kits would rock that space.....currently I’ve got 3 x100w closet cases and they seem to do a decent enough job, but If i could start pulling a pound out of there that be even better
Ya, they have a spot on their webpage where you can put your email to be notified when the item is back in stock......they pretty much went out of stock on the 260 qb’s within 24 hours last time. Gotta be quick. I’m just not sure what kinda duty I would have to pay on those.....I inquired with hlg and they said they would declare the two lights at $49 each. So does that mean I only need to pay the duty on $100???
I’ll let you know...I have 4 of the 260w kits on the way.
Much appreciated. From what I’ve read you pay the duty on whatever the shipper declared it at......in the case of the 260 w qb that would be $49 each
You must be outside of the US I presume?
