Looks like an old light. At first I didn't notice that one bulb was missing. Then, when I did notice, it reminded my of a birthday cake but instead of celebrating getting older it is taking away years and counting down to the end.
Delightful; wonderful use of available light, and a shot that fits in perfectly with the theme here. How many times do we go in a room and never notice what lights it up? Nicely shot here, and I like the minimal editing treatment; works well here.
