There are many reasons this isn't working... first being that the inductive clamp on top is what is used to determine AC current... supposedly to a very high rating according to the listing. Second being you are measuring the current in the wrong location. You want to measure current at the wall...
I figure if I can get most of the light directed down in one bounce off the reflector, rather than possibly quite a few of the tent walls, that's a plus.
I'd like to get something like the canopy substrate and some CV drivers and just keep adding a handful of COBs every month or two until it's just a solid block of light...
