[Solved] Auto-build COB lamp - less watt then calculated?

[Colpevole]

Voltage reported are measured putting multimeter in the two output wires of power supply with cobs connected and turned on.
today i'll check resistence of dimmer and current.

Solved.
I have done a mistake on led wiring..
With correct series circuit, with 100% of dimmering i have 160+237w=397w

Now i have set all cobs to 75w, so i use 375w in total for light.

It's a good setting for these cobs in your opinion?
Look like a big sun eheheh!

Thanks to all for help!

I am glad you figured it out.
May I ask you where did you get the Luminus cxm cobs?
