As you can see as a lantern a weilder of light constructs they would be wtf owned.Add that with his impressive displays of magnetism (i really don't think pulling a small ring from kilo's finger is going to be as had as lifting land masses or creating complicated machinery with his powers of magnetism.
Also it really doesn't have to be solely metal for magneto to bend it to his will it just takes more concentration. Anyway Magneto in his prime should beat Kilowog. If it was current or just average magneto then yeah good herald level GL should beat magneto.
They don't wield "light". In addition, they can control the EM spectrum as well. In addition to gravity, transmutation, atomic control, etc.
It doesn't just create constructs, just as much as Magneto doesn't just attract/repel metal.
