A while back I was obsessing about 50s style diner pendant lights (or dive bar lights depending on your point of reference). I was looking for the style of light pictured above and couldn't find anything. I should have known that Retro Revolution would have the answer. The exact light I had in mind was the Moe Light Fiesta multi-colored pendant light in red, orange and yellow. Fellow nerds will know it as the lights that they had in the bar on Scrubs.
However, my better half pointed out that if you hang a pendant light in an area that was formally a formal dining room, people will expect you to put a table under it. That, or you should expect people to bump their heads on it. So my obsession with finding a multi-colored pendant light is over. However it looks like Moe Light made a Fiesta hall light too.
