What does the lamp in the room mean?

The lamp is your Service Streak. It burns brighter as your streak grows, from unlit at 0 to its brightest once your streak reaches 30. For Kingdom Publishers the streak counts months, so it is brightest at 12. If you turned off Show streak in Settings → Preferences → Streaks & Badges, the lamp keeps a steady medium glow and no streak number shows anywhere.
