<p>A ballast circuit system (100) provides for efficient starting and operation of high voltage discharge lamps (50) using a common 120 volt AC power source. As a result of this improved ballast circuit system (100), the necessary high voltage is generated from a normal 120 volt AC in such a way that there is low power loss. The system efficiency allows for use of plastic fixtures and small size packaging of the discharge lamp (50).</p> |
