Lighting ?'s about converting mars type led to cobs

[nudd]

Dan you have the wrong driver for the way you have wired with that driver you should have wired them parallel not in series
to make them work take a wire from each + and a wire from each - connect all the + to the + side of the driver and all the -
to the - to the - side of the driver
the driver runs at 3900mA so 3 cobs should run at 1300mA each
hope this helps

Thank you so much! Going to give it a try now.

That was it nudd!!!! I think I may be blind though. This thing is bright! Thanks again.

The new light is hung and doing it's job. Sooo bright. It was great taking my 3 "300 watt" purple leds out of there.

Thank you very much for all of the help and advise.

BigSm0, you gave me that bit of knowledge I needed to get this done. Thank's for that!

Well.. ? Show us images you tease

 

[GoatFarmerDan]

I will get one up soon.

I still need to clean up the wiring a bit.







So far so good though!!!

 

[BigSm0]

Thanks for clearing up the wiring issue nudd.

Hey Dan that's excellent man. Even better that you replaced 3 panels with 3 cobs lol!! These things are no joke. I really think the blurple markets going to be changing real soon and we will see a lot more white lights hitting the market. Little work, little money and you sir are into a very efficient setup. Enjoy the lower amount of heat and electric bill savings.

For the record I spoke to the company that sold you the driver and have also seen this problem more than once. I suggested a quick video linked showing how to wire in each form or atleast an explanation.

 

[GoatFarmerDan]

Thanks BigSm0. Yeah I was clueless as to why it wasn't working. Everything I read and watched for this setup was series wiring. I never even considered doing it in parallel. Thanks again nudd.

Is it still running at around 75 watts per cob with this wiring?

 

[BigSm0]

Yes sir.

Series wiring divides the voltage of the driver and not the amperage.

In paralell it divides the amperage.

Your driver is 4.25amp tuned all the way up. Divided by 3 cobs means each cob is receiving 1.43 amps each. The citizen 1818 is 52v.

Ohms law ------amps x volts = watts

52x1.43= 74w per cob.
