low pressure sodium or high pressure metal halide?

I did not watch the videos but feel I don't need to. I work on broken things everyday, it is what I get paid to do.
it all comes down to a cost-benefit analysys.
most people prefer cheap and fast. not good.
you can make a triangle out of cheap, fast and good.
pick two, you can't have all three.
