About this game

Sodium Yellow puts you in charge of a high-pressure sodium lamp arc tube workshop deep in the night. Inspect translucent ceramic arc tubes, seat the electrode assemblies, dose the sodium amalgam into a tight golden window, then fire the sealing torch while the vacuum pumps run. Overheat the pinch seal and the tube cracks; skimp on the dose and the lamp fades. Every lamp ends on the burn-in rack where its true luminous flux is measured.

Work order by order: road lighting, grow lights and port flood lamps each demand different power and flux targets. Your pay scales with luminous flux and sealing yield, so precision matters.

Spend your earnings on six real workshop upgrades: a precision dosing machine that widens the dose window, an automatic sealing torch with forgiving temperature control, a vacuum pump unit that steadies the flame, a spectrum analyzer that reveals predicted efficacy, graded ceramic tube selection, and a twin burn-in rack that doubles test throughput. All equipment is saved permanently.

Features:
- Five tactile production stages with timing and hold controls
- Order-based progression with rotating lamp specifications
- Income based on luminous flux and sealing yield
- Six functional workshop upgrades, all persisted
- Fully synthesized sound effects, no audio files
- Dark midnight blue and sodium gold art direction
Run a night shift building glowing high-pressure sodium lamps.
