This is the six arm chandelier from the Tahoe collection by Hinckley Lighting. I have the matching 3-arm version in the living room, too. When Ms. Bungalow and I bought the house, the previous owners specified that they wanted to keep the antique chrome art deco fixtures (not original to the house) they had installed here.
In the middle of a move and short on time, we found these lamps at a lighting store near our old neighborhood. They fit the house style well enough that guests sometimes ask if they are original. As my restoration sensibilities have developed, however, I have wished to someday have an antique or reproduction fixture in these spaces.
