Maximising Bulb Life
| To achieve maximum life from an automotive bulb there are some important points to consider. | ||
Rule of thumb: |
||
| • | 5% over-voltage halves the bulb life | |
| • | Headlamp bulbs are rated at 13.2 volts. Signal & Marker bulbs are rated at 13.5 volts. | |
| • | Light output of a tungsten filament light source is dependent on voltage. Low voltage causes low output and low life, especially for halogen bulbs, because regeneration does not occur. |
|
| • | Over voltage causes excessive tungsten erosion and significantly shortened bulb life. | |
