Basically, you're only limited by upper voltage limit of your driver and/or how big losses you can tolerate.When you guys run your drivers remotely how long can the cord be from the driver to the cobs? Just looking to make it as cool as possible.
Thanks! That was just what I needed and how I needed it! You're awesome.This would be my guess. edit: Guess only, you should check with a multimeter.

You can test it easily with a multimeter. Use continuity (beep) mode. Then attach one probe to any pin on the cord and with the other check all the wires on the other end until you hear a beep sound.
Here's a nice tutorial.

You can go pretty long with them. The longer the run , the thicker the wire gauge you should use. Can't really be anymore helpful then that with out more info.When you guys run your drivers remotely how long can the cord be from the driver to the cobs? Just looking to make it as cool as possible.
Just popped in to say that your diagram was 100% correcto!This would be my guess. edit: Guess only, you should check with a multimeter.

LMAO @ any month now
"So once you have that data, it is amps * volts = dissipation Watts
Then dissipation Watts divided by "power draw" Watts = efficiency"
I am new here. I have been going over these posts and those on other forums. I just signed up with RIU. I don't know the proper way to format this question .
I keep getting hung up on "dissipation Watts".
Is it the actual power used by the COB including heat loss and light produced? Is it the same as what I would think of as actual power draw when referred to an LED light? Is my 600 watt HID at 600 watts of dissipated power?
How does dissipation watts relate to the figure of 25 watts per sq ft for example?
Hope you can help. I find myself completely glitched with this concept.
Thanks
OK. I think I got it. So at 50% efficiency to get 13.5 PAR W/ft you would be at 27 dissipated watts per COB.Yes 16 gauge would do the trick. You can get it with nice thick jackets from extension cords at Home Depot ~$0.25/ft or even cheaper from the lamp cord style extension cords.
@good light dissipation watts are referring to the light and heat generated inside the LED. When we say 30W/ft² that is referring to dissipation power. It would be more clear to refer to actual light power (PAR W) so if you know you approx LED efficiency you can estimate that. I use about 13.5PAR W/ft² which I think is a good compromise between nug size and efficiency.
Yeah that sucks. I would press from them to pay return shipping. Either way you should get your money back if not from them Ebay will give it to you. Takes some pictures of the amp readings with the driver in it, so you have proof.
So, am I reading the picture wrong or does it say 1.35A +/- 5%? Because then the 1.25A is actually almost within tolerance. I'd say the driver is working as advertised.lol it's actually 1.25 amps I was doing it wrong didn't get between the circuit... It's stopped jumping around after that solid 1.25 basically I got jipped it looks like.
The driver on his store was not the same one I got I ordered 1.4A driver that was power factor corrected. He sent me a cheaper one then I ordered and then told me the sticker was wrong and that it was in fact 1450mA(which was bullshit). This equates to wattage/ounces/efficiency lost in my grow. We are just pointing out how I didn't get what I paid for. I have more drivers coming from a differ seller now. And the original seller is now not answering my emails after I sent him a picture of what his driver ran at. Therfore I have to settle the dispute with eBay.So, am I reading the picture wrong or does it say 1.35A +/- 5%? Because then the 1.25A is actually almost within tolerance.

It's just for mechanical protection, you can cut it off.Just popped in to say that your diagram was 100% correcto!
Edit: Also, what to do with the little metal wire that is poking off to the side??
70 cobs now, its a bit big.55 COBS!
DAMN SON!
There are some calculators on the internet that you can use to calculate the wire you need and the maximum length.When you guys run your drivers remotely how long can the cord be from the driver to the cobs? Just looking to make it as cool as possible.
