The light output of a lighting arrangement is adjustable at two levels by, for example, &ldquo;toggling&rdquo;. During a predetermined time interval immediately after ignition, the lamp is supplied with additional power to heat up. Immediately after stationary conditions have been reached, the light output is automatically adjusted to the lowest of the two levels. During the predetermined time interval, the light output is also controlled so as to be at the lowest of the two levels, so that relatively large changes in the level of the light output during the predetermined time interval, and immediately after it, are prevented.
