- For
- Readers curious about sodium lamps and the color of street light
- Worth noticing
- It says cold lamps begin as dim neon red, then turn orange as the sodium vaporises.
Field notes
The explanation is arranged as four short sections, with a wavelength scale marking 589 nm among the visible labels. Its warm-up account says the lamp starts as dim neon red before the sodium vaporises and the street turns orange. The navigation lists five language options, including Klingon and Sindarin; the extract does not establish whether each option leads to a translated page.
