+The LC-516, produced by Polish tube manufacturer Dolam (later known as Unitra Dolam), is pin-compatible with and visually similar to the Soviet IN-1 Nixie tube. However, unlike the IN-1—an early model with a relatively short lifespan—the LC-516 is mercury-doped, significantly enhancing its durability and giving its glow a subtle bluish tint. The LC-516 features a slightly smaller glass envelope and digits compared to the IN-1; a comparison between the two is shown below. Additionally, Dolam manufactured a version without the phenolic base, designated as the LC-513.
+
+As I am not aware of a datasheet specifically for this tube, I have provided a link to the IN-1's datasheet below. Since the tubes are compatible, the relevant specifications should be identical.
