<p>An improved high frequency ballast is disclosed. The high frequency ballast establishes a lamp current (IL) for a gas discharge lamp (10) during a starting operation of the gas discharge lamp (10) wherein an operating ampere level of the lamp current (IL) facilitates a substantial achievement by the gas discharge lamp (10) of a color specification associated with the gas discharge lamp (10). Thereafter, during a stable operation of the gas discharge lamp (10), the high frequency ballast applies a frequency modulation to an operating frequency of the lamp current (IL) and/or an amplitude modulation of the lamp current (IL).</p> |
