Small fluorescent light built for a Soviet spacecraft (probably associated with Soyuz), measuring 6.25″ x 3″ x 2.25″, with hand-painted markings on the edges in Cyrillic: "Cд1-5M, N86-018" and "33.10-H33-X1." The plastic lamp assembly is secured by metal latches on each end, and can be removed to reveal a power port in the metal base; the assembly is marked "бц N84-087" underneath.
