Well I tried to do the links in the message- here they are the cumbersome way.. Sorry first http://www.google.com/products/catalog?q=butler+3&hl=en&cid=6369528097606530219&ei=GLL7S96gFJLolAe6nMzYBw&sa=title&ved=0CB0Q8wIwBTgA#p this is the second http://store.starrynightlights.com/sgl-40022-05.html

In my opinion they do not necessarily need to match, particularly because they are different walls. Having complementary lights from the same style line could be nice as well. For one of my clients I used that Kovacs style on both sides of mirror of vanity dressing table and they worked well. There were 2 bulbs per light instead of only one allowing for more light, the glass was frosted providing a softer light without it being blinding, and the light shone toward the face instead of downward (this would be particularly the case for the blue I would think). The clear lights are pretty however you will want to see how bright they are. I have found some, when hung at or near eye level, are blinding and uncomfortably bright on the eyes. The frosted finish helps tone that down.

Yes, this is visual comfort Sargent. See link. I love the unique shape ...I've never seen another like it. There is another thread on houzz by Minnesota Mary and she used these pendants also.

I would first mount the mirror to get a sense of the look, it would help us help you also.
