try 1 more time no pic loadedehhh clicked the wrong button, here it is
The only shitty here is reply by shugglet and @frica -
You cant see the irony here? lol How bout you answer the point I made in my previous post, Ill even restate it for you...You can call me Trump - i call you fucking NAZI - OK. ?
That is simply shady business and you probably fucking know it. Thats why you always ignore it.You realize in your comparison you are driving the CXB twice as hard and its still still more efficient... Think that 147lm/w would go up if you ran both at 700ma???
Do you really have to put a processor fan on each heatsink? Do they give off that much heat? couldn't one fan blowing cross the top be sufficient?A few pics of my first cob build. I still have some finishing to do but I've been running it just for testing temps and draw etc. The light is 24"x24"
and it is intended for a 3'x3' tent. The fans are not connected yet because I was an idiot that connected AC to the DC side of the power supply. It appears to not matter that much because at full blast after 3 hours, the hottest heatsink is just at 99 to 101 degrees. Looking forward to my first legal grow!

it depends on the heatsink style. the fin style heatsinks would hold heat between the blades if it wasnt quickly forced out. A single fan wouldnt reach all the grooves appropriately and you would result in hot spots and possibly burn out a few chips. if you were using passive heat sinks this would be differentDo you really have to put a processor fan on each heatsink?

It also depends on heat-sink material type and thickness etc, and wattage through cob(s)Do you really have to put a processor fan on each heatsink? Do they give off that much heat? couldn't one fan blowing cross the top be sufficient?
Hell yeah bro... could you break down what lights you are using? Thank you.. nice even canopy you got going on also... what strain are you running?GroPro v3.2 in action

Very nice. I like the detail to neatness by tie wrapping everything. Very clean. Same with your control panel. One question, why didn't you wire the power supplies directly in the power boxes, vs. going to plugs and outlets?Citizen 1212's, Intel CPU active heat sinks, Meanwell 320's. 16x COB's and 2x Meanwell 320's per 4x4 grid.

I have 2 tents, and in my Cree tent I run 2 fixtures in a 2x4 and each fixture is 6 cobs off a 240 watt driverMine give off little heat. In fact I put my seeds/rapid rooter in a cup on top the heat sink to sprout. But I am running 6 cobs off 1 240 watt driver
Setup is great!Citizen 1212's, Intel CPU active heat sinks, Meanwell 320's. 16x COB's and 2x Meanwell 320's per 4x4 grid.

Yeah, I figured it was something like that. Still a sweet setup!I was originally going to do just that, have every set of 4 drivers wired in a junction box, but I guess I liked the idea of being able to unplug one and swap it out if needed..
I like that you measured them and wonder why I didnt lol.I measured each driver then labeled them, that's why you see the odd numbers on each driver, I'm just weird like that lol.
Nope, this is generally so.I thought everyone always talked about using B series drivers with the dimming leads capped off to get a higher output wattage? This is the only B series driver I have, I figured it was just a fluke that it had much less wattage than any of my A series...
