Hi all.
Sorry to crate a thread about this, searched for info but still uncertain and do not want to mess and neither can I afford it to be honest.
So I finally could afford to pull the trigger on a small space cob build but math is my weak side and must could not figure out AWG but Cobkit told me solid 18 gauge, build consist of HLG-120H-48A and 2x 3500k CLU048 1818 90CRI and might just swap to x3 or x4 1818's later on to improve efficiency a bit time will tell? Plan is to run actively cooled heat sinks ala CPU coolers cause aluminum heat sink is pricey here in north EU and if needed a fan on driver too, looking to maximize the parts soon to arrive.
It was a long time ago I build a light now and used individual constant current drivers back then so this is all new to me and from what I understand I will hook up the cobs in parallel and try to run a very short loop with driver located real close to lights and all that..
Not certain about final cable lengths but I will try to keep the loop real short about 2 max 3 foot if possible excluded whatever is already attacked to the driver itself? My biggest problem is finding the correct wire/cable (whatever you English natives call it), conversion tell me 18 AWG is 1.02mm diameter or 0.823mm2 cross section but I having a hard time to find it cheap and easily accessible here in north EU to receive it asap at least without crazy shipping costs added, possibly I am not sure what to search for?
I can find 20 AWG singles and 2x0,75 mm2 which is in between 18 and 19 AWG and those are very common but most 0.75mm are stranded, some solid core is available but they felt very stiff, next common size is 1.5mm2. Is there a big difference between 0.823mm2 (18 AWG) and 0.75mm2, I feel like I want to take full advantage of what I have saved up to and bought and already made some sacrifice in regards to efficiency by only affording 2x 1818's for the HLG-120 48A. I cannot afford building super efficient at least not for the moment, but electricity is expensive here and in the summers I have to fight heat too.
Cable/wire recommendations would be highly appreciated.
