(4) CLU048 Citizen 1212 (3000-4000K) $32 -Cree are still over priced
(4) BJB holders (solderless) -$10
(1) HLG 185H-C1400B dimmable driver -$50
(4) 120mm pin fin HS -$48
(1)100K pot -$3
approx 12' of 1" Aluminum angle made to approx 20" x 20" -$14
M3 Screws/ Eyebolts/ Hardware/ 18ga. wire/ Thermal compound/wire nuts etc..-$20
An inexpensive 200 total watts (slightly more if left uncapped) of dimmable light fit for flower in a 2x2.
Approx 50W per sq ft aint nothing to sneeze at.
You could probably do this build for about $170 or so if you really bargain hunted and/or found a spot to order multiple items in one go to save on shipping. This will also be running quite efficiently at 50W per cob, meaning less heat/HVAC needs. Sell that mars light to come up with the difference between your $140 budget and the cost of the new light build.
I use mine in a 2x4 for mommas/cuts etc. I opted to get waterproof junctions etc, but you could build a bare bones light
that would rock out in your tent.

This is a build I did with cheap Aliexpress driverless cobs haha, but it gets HOT SO MUCH and I think draw 350watt and it´s so much for my electricity bill, I live in Colombia (but I can purchase things in USA and bring it here without problem). So I want to use this heatsink, the fans are thermaltake and don´t care about noise. What do you think?
Another question: can I use this: https://www.amazon.com/HLG-185H-C1400A-Supply-Single-Output-71-143V/dp/B0161ZX6SU/ref=sr_1_1?keywords=Mean+Well+HLG-185H-C1400a&qid=1554763999&s=industrial&sr=1-1-catcorr ?? I see that have dimming installed maybe it´s better for me that I don´t know a lot about.

What do you think about buy the dimmed dirver Not the B versión? Thanks a lot for al the input! I’ll buy everything. And another question, whats best 3000K or 3500k?

If it's for flower only use 3000K if you plan to veg with it, half power and 3500K. Then full power at flip.
Either a version or b version it doesn't really matter. The only difference is that the B version you have to actually add your own 110K potentiometer. But it can dim all the way down to almost zero. The A version useuses a screw underneath a rubber stopper in the front of the driver and dims only to 50%(which is really all you need.)

Oh I see! My plan is veg and flower so i’ll buy 4 at 3500K right? And a 110K potentiometer I see better Option to control! Thanks again my friend!
The only concern I have right now is where I’ll Put the driver haha

Mount it to the frame. If you mount it to the frame and use a grounded cord, it will be grounded through the case of the driver to the frame.

Well! Thanks friends for all the advice. I´m reading a lot about everything and see the famous Quantum Boards, what about? They´re better or it´s only hype? Also use a driver right? It´s there anyone for my bucket?

For that small of a space, definitely mount the driver outside the tent. Heats a bitch

Hi my friends! I’m thinking in build a diy fixture for the 4 Citizen with CPU cooling Heatsinks. A local Store have 4 of this: https://www.amazon.co.uk/Original-Socket-1A0297200-Cooler-AMD/dp/B00C76B73E for about 4$ each it’s very cheap.
The Power Consumption (TDP) of AMD Athlon 64 X2 is 89 Watt according to some sites, I dont know if I can calculate that way.
Will they work well? I dont care about noise. Thanks

Fuck Ya they will. Those are the best looking ones I've ever seen for a COB to be used. That's crazy.
Definitely buy ALL OF THEM that he has in stock at that price. Not kidding... You can't turn that down for future builds.
Use an APV-12-12 to run the fans. They probably pull 0.25a so you can run 4 fans on one driver.

Hey TB.
One problem is yourtent size, its a bit short for cobs especially 80w cobs. Id go for 4 or more cobs at max 40w each. Or some ledstrips: samsungs or bridgelux.

There is no such thing as a 110k potentiometer, you need a 100k pot. Due to manufacturing tolerances, many 100k pots are often as low as 90k and 100K (or higher) is needed for 100% power. The common solution is adding a 10K resistor in series with the pot.

Thanks for this. I was looking the 110K

@TomBombadil420 forgive me if I missed it, but what are you using to drive the CPU coolers? You won't be able to wire them to the COB driver, so if you don't have one yet, I would grab an APV-16-12.

Thanks! I´m driving with an old 12V router adapter and works great!
