Creating micro waves very very inefficient 50% to 75% at best

Yes, but you'd need thousands of LED's to generate 35KW of energy. A decent sized magnetron from an industrial microwave oven can do that rather easily. Plus, it's not the initial thrust that matters, it's the cumulative effect of that thrust over time which produces the high velocities. Same principle works for an ion engine.
