I'm putting a proposal together using Unique products. I was wondering what MR 16 is the best/most popular among the choices available. Is there pros and cons that make one rise above the others? The install has to be brass, so the copper choice is out. These will all be ground mounted up lights. As for wall washing, I'm assuming that the Starburst is the fixture of choice? But I'm curious about the even spread of light on a light colored surface due to the lamp assembly being mounted to one side of the reflector. Does this cause funky shadows or striations in the beam pattern on a wall? Thanks.
