Two bulbs cheek-to-jowl are going to produce more downward light than one bulb
with a reflector. But use twice the watts of one bulb.

A bulb that is mirrored on half the surface is going to produce more light out
the
non-mirrored side than if it wasn't mirrored. Half the lumens do not disappear
(nor just convert to heat).
