Of course MV Lamps are better since they have near white luminance compared to the boring yellow tone of SV Lamps.

On an afterthought, authorities could also think of using some bright CFLs instead of MV Lamps, since the power consumption will be much lesser. recently I replaced an aging 7 year old MV Lamp which lights up our garden (100 Watts) with a 25W CFL. It gives the same lighting.
