Yes you can put the driver anyplace, put the driver outside of the grow tent for less heat, put the driver inside for more warmth if needed, most of us put the driver near the cobs for convienance, it makes the light asingle unit, compact, easy to carry and move around, but you are not bound by rules with diy place the driver anywhere and run the wireswhy is it getting redish afterwards?
edit: also, why you guys bring the driver if needed, o close to the lights? I could put it close to the plug in the wall right? No need to have the driver in the tent / room
Yes, I just think that it is way easier to move without any wire on it, basically. What heat are we talking about here? What are 4 cxb's doing? What is the driver doing? I cannot imagine that a small driver creates such "heat" but why not significantly lowering the ppm of the exhaust fans. No need for 100%. I own leds and they are far from hot. My better ones are so good actually, I have to turn on the heater in the winter (but they aren't crees)Yes you can put the driver anyplace, put the driver outside of the grow tent for less heat, put the driver inside for more warmth if needed, most of us put the driver near the cobs for convienance, it makes the light asingle unit, compact, easy to carry and move around, but you are not bound by rules with diy place the driver anywhere and run the wires
What are you running for ventilation? Seems like if you did a negative pressure setup with high air movement, it should be cooler. I know my 10 sq ft room was about 2-3 degrees warmer than the house temp (75 house, 78 room) and I had a 440CFM fan exhausting and passive intake bringing in cool air.no there are ways to hook a single driver to multiple cxa's,,
but most people use the single driver method
my light set up does rise me 10 degress, its doing it right now, its 63 degrees in my bedroom and 73 in my box,
I like the shrink tube cable plan, sounds great
I really like being able to manipulate the temps by using the lights, this will give me plenty of temp options this winter,, so when I crank the lights up, I can just speed up the exhaust fan to compensate and set my room temp right where i need it to be just by using the lights and fans, pretty cool,, no need to use heaters,
You are using the test current voltage(36v and 1900ma).
When ran at 1400ma the Vf is under 35.75v(~35.59v)...and is literally the perfect match. Full voltage on the string is what drivers love.
Hey there - awesome post this is. I'm just curious why you are going for 3000k instead of 3500k? I notice there seems to be a lot of 3000k in stock at digikey.Hello all,
I have recently built a cxa3070 3K using a meanwell driver, as well as 4 Vero 10's. I love them and want to add more. With the CXBs coming out for a few bucks more, I am ready to pull the trigger.
I was thinking of adding
(2) CXB3590 3Ks @ $59.50 from Digikey
Meanwell HLG-185H-C1400B @ 64.95 from Jameco
Total = $183.95
I was thinking of running the LEDs in parallel so 72v @ ~.700A
Any thoughts or suggestions?
Oh and I would like to order from US only, no international shipping please. I am still waiting for a driver from China, its been over a month now lol I learned my lesson.
@SupraSPL I would like you to give your analysis on the setup, given I love the 3070 and driver combo you suggested.
I chose the 3000k because it was readily available and cost effective.Hey there - awesome post this is. I'm just curious why you are going for 3000k instead of 3500k? I notice there seems to be a lot of 3000k in stock at digikey.
This has been a really interesting read, im on my first grow with a mars hydro 144 reflector in a 4x8 tent with three plants currently in flower and so far so good, im happy with my led but i would like to upgrade soon and this diy cob is something I've been researching relentlessly. Theres one question i have, i would like to keep it simple and start slow with these types of builds, is there a driver than can power a single cxb3070 as efficiently as the builds mentioned in this thread. I cant seem to figure this out.
