also you kind of need to know your current to calc that, use a second meter if you have that. i forget that part as im usually doing this with a regulated power supply

Hey guys so here is my issue, my light will not light up.. lol

The details of my light are as follows


Driver = Meanweal 185H-48A X1
COBs = Citi 48-1212 X 4
Ideal holders X 4
ideal reflector adapters 50-21--AN X 4
Angelina reflectors X 4
Heatsinks cheapos X 4 (But mounted on a Hugh piece of aluminium)

On the AC side of the Drive i connected the wires Green to Ground, Blue to white, and Brown to Black.. I checked the outside / DC side and i was getting 49 volts. From the outside or DC side i wired the red from the drive to the + of the 1st COB, then from the - side i went to the 2 cobs + side and continued till the last COBs - side which ran back to the red wire of the Driver.. Plugged it in and nothing..

I ripped it apart twice thinking i did something wrong but i cant figure this out.. How can test the COBs? Could the holders possibly be the issue by not making a good connection? Could the Cobs be bad? Any input would be great,
