An electronic ballast (12), which is known per se, for a lamp (14) which is designed for continuous filament pre-heating is used, according to the invention, in an environment in which the temperature is-20°C or less. When driving the electronic ballast (12), the continuous filament preheating of the electronic ballast (12) is activated at a first predetermined time, and the process of starting the lamp is activated at a second predetermined time. The electronic ballast (12) can be driven as appropriate for the environment (16) in which the electronic ballast (12) is located, by means of a suitable digital addressable lighting interface (DALI) controller (22). |
