Is a dimpled or polished reflector better at reflecting light?

A dimpled pattern will be better, as they produce balanced light footprints, the flat polished type can produce hot spots and uneven light distribution.

(snoofer) High quality reflectors have a 'hammer specular' finish (to distribute the light evenly) and titanium dioxide (for max. reflectiviety) paint. The surface feels slippery.
