Just got finished putting together a unit of four 50 watt crees with a hlg 185h c1400b driver following the build on here. the lights come on but are really dim. the potentiometer does nothing so i took it off but that didn't effect the brightness. strangely after it's unplugged the lights stay on at the same intensity for 6 or 7 seconds.
How it's wired up:

yep, brown is positive... i put a mark on the port of the cobb holder closest to the + sign. double checked too tho. if any of that was backward it just wouldnt have come on right?
I don't have time to check the data sheet but have you added up all the voltage totals for the cobs? Apart from a dodgy driver or dodgy wiring or connectors the only thing left is to ensure that the driver matches the LED's
