Why Replace Your Philips SGS203 70W SON-T Lamp?
High-pressure sodium lamps last a long time and are very efficient. But, like all lighting technologies, they will eventually wear out. Here’s why replacement is essential:
- Diminished Light Output: Over time, the lumen output decreases, reducing visibility.
- Color Shift: As SON-T lamps age, their orange glow may turn white or pink. This change signals an end-of-life (EOL) failure.
- Increased Energy Consumption: Older lamps consume more power while producing less light.
- Flickering or Cycling Issues: If the lamp keeps turning on and off, it means the ballast might be failing or the lamp is being overdriven.
- Upgrading to LED: Many users think about switching SON-T lamps for LED options. This change saves energy and improves light quality.
