Hi Guys.

I have a 200w cob Kit consisting of 4 x 50w clu048 cobs.. It was working just fine 2 days ago.

Yesterday i noticed That only 1 cob was working. It was the First cob in the series string.

I looked for loose wires and If everything was connected Well with out help.

Then i took the First cob out and Then the 3 others Are working just fine.

The Thing is That All the cobs Are working - just not together :/

Is this the First cob That is broken All though Its lightning up alone?

I was thinking That it Maybe couldent send the current on to the second cob anymore?

It doesent work If i put it in the end of the string either.

I would really appreciate Any help provided..

Thanks in advance

Best Regards

Make sure that you dont have the holders too tight, maybe causing a short somewhere.

We can't help without more information. From you description, I'm wondering if it's actually a parallel string. BTW, in a series circuit, all cobs run at the same current.

1) We need good pictures of the wiring.

2) What driver?

3) What kit? A link would be good.
