Just the lights, no outlet required -[ HMM ]-

A set of battery-powered LED Christmas lights, bunched together to fit within the 3" (76.2mm) size limit.

 

Of all the decorations and iconography of the festive season, the Christmas light is my favorite. I may have a soft spot for the old-school incandescent bulbs, but the LED has unleashed quite a wave of possibilities without the shock (sorry) of insane electricity bills.

 

Taken through 2.1 stops' worth of neutral-density filters.
