GDL Bulbs (2002-2004): Design: Bulb
The light source consists of a discharge pipe surrounded by glass which filters out damaging UV radiation.
- The discharge tube is filled with a number of chemical compounds including the noble gas Xenon
- A light arc is created by an electrical discharge between two tungsten electrodes
- Because the bulb does not have a filament it is less susceptible to bumps and vibration
- Bulb designation: (special for reflector system).
- Power consumption: 35 W.
The bulb contains mercury (less than 0.5 mg) and when discarded must be treated as hazardous waste. Hazardous waste must be handled according to the relevant statutory regulations, see also Volvo Car Corporation's "Waste Management Guidelines for Dealers".
