Lets not forget that 50% of the radiation coming from a 1000 HPS is coming from beyond 180°. So this light has to be redirected in a reflector that is generally specifically made for diffusion. 100% of the radiation is in 180° field necessitating way less "optical correction" vs a bulb fixture. As far as optics costing light a high quality lens loses no more than a reflector such as a Ledil Angelina. As a matter of fact a proper optic can be more efficient than most off the shelf led reflectors.
