Where did you get that beast and what did it cost? Looks like a hell of surface area.Can I handle 200-210 watss withtwo driver hlg185c1050b and lpc100-700
On this heatsink 40x20x8cm
Good Luck!40 euro apprx.
but Im confused as hell
I do not know where Im gonna find screws for the holes on it and bunch of stuff like these little shits Im messing with those issues right now please wish me a good luck to finish this project I have been struggling for a 2 two months
what about your view about the its passive capabilities ?
40cm long of this is itView attachment 3752486
would you please tell me more about the green cable on your heatsinks sideSo, I may have grossly overestimated the passive cooling abilities of my bars. After running for an hour or so, these guys get pretty hot... Not so much that I can't keep my finger on them, but seem to be much hotter than I would have thought... Certainly above 85° by feel alone.View attachment 3642791 So, here's what I'm running...
4 cxb3590 3500k (72v) on a meanwell hlg-185-700a. The sink is the 7.28 profile from heatsinksusa at a length of 24". I'm guessing that im losing all kinds of efficiency here, and possibly might damage the CoBs at full power?
Clearly, I'm going to need some fans, so would one large central fan be enough, of should I put two equidistantly placed on each bar? Any recommendations?
Absolutely you must ground your driverm green cable from the plug goes to a mount on the heatsinkwould you please tell me more about the green cable on your heatsinks side
I think its the one grounding how it works and how should I apply to my project is it a must or precaution can be taken ?
Plug to wall ground wire>driver ground wire> spliced off with another wire that goes to heatsink or frame.well is it gonna directly from the driver green to heatsink thats it ? or should I also connect the plug cable to Im in EU
I watched all of those videos and read most of the articles here. Maybe some of the articles could not be understood by me but my heatsink fins has different shape not flat like vibrated water shape in out with tiny measures it definetely increase area
assuming flat and making calculations give me around 100-120 watt but with the cover and the shape of surface increase area can cause it up to where ?
does anyone know ?
This is basically my light.5x CXB3590 3500k $200
5x Ideal 50-2303CR $15
5x Ideal 50-2300AN $10
5x 180mm pin fin heatisnk$100
5x reflector's
1x Meanwell HLG-240H-C1400B$70
Do I need 180mm pin fin heatsinks or can I go smaller?
Anything else you guys recommend to change or just order away?
Is there anything else Cree is coming out with that I should wait for?
Oh wow 120mm? Awesome feedback, I'll look at some slightly smaller ones and save some coin.This is basically my light.
You could use smaller heatsinks if you want. My light is made with 120mm sinks.
You need thermal interface paste.
You also need a pot for the dimmer on the driver ($1).
Perfect I'll order one along with everything else.The 120mm sinks are a bit hard to find, I think they're a very popular size.
I think you NEED the pot. That is a dimable driver and I think it needs the pot to complete the circuit.
Expert I am not.
It is a 10K pot. Common and available(Radio Shack, Amazon...)
Very nice!!! I have more of a horizontal growing space. I'm still finishing up my soil grow so I'm not in an immediate rush. I plan to buy the lights in the fall and start a dwc grow.Mine...
