What gauge wire for remote drivers?

Hey All,

I am now building 2 lights with 5xcxb 3070 BB 3500k with HLG-185-1050Bs, Currently working on the 1st. I have a 48 inch heatsink. I want to run the wires to the center of the heatsink, then up and out of the tent to the driver, instead of having the extra heat in the tent.

Do I need to run larger gauge wire from the first and last COB back to the driver? I am hoping for around 8 feet from the top/center of the heatsink to the driver. I don't want to melt anything but I don't know that I could honestly get a 16 gauge wire in the solderless holders I have... any advice?

I will hopefully post some pics tonight, I didnt have the 140mm fans i needed (damn you 120s) so I am waiting on the correct fans but I should be able to plug in and take a pic at least once I get this part figured out.

I ran multistrand rotor cable. 18 g 8 ft. Works great.

Secondary side current of the driver is low. Voltage rating on the rotor cable is 200v. Ham shacks sell it.

I have used 16amp power cable from car audio setups. Works well and never feels warm.

No it is rated for up to 16 amp. They do a 30 amp version but it was really thick and seemed overkill.

Seems to have changed slightly since I bought it as it's only rated for 15amp now lol

Ah i see now, i had something like this stuck in my mind.

home depot sells 18/2 solid wire for doorbells. fits the ideal holders and is two insulated wires in a jacket

1A is nothing. like a tenth of a volt max drop over 10ft of 18ga
