Problem is that doesn't take into account the short service life of halide lamps compared to fluorescents. Within 6 months or so the T5 will be ahead of the halide. That is why the big push to convert the Hi Bay lights over to T5's. Sodium lights are not really usefull for indoor lighting because of the color.
