Summary:Dimming fluorescent lamp solid-state ballast. The ballast is adapted for automatic sensing and control of lamp temperature to dim the lamp to an optimal operating temperature, such as that at which the light output is a maximum per energy input. The ballast is also adapted for manual continuously adjustable or multi-position stepwise dimming control, which may include such an optimal setting. Other available dimming settings include undimmed or maximum light output, and/or the lamp's minimal sustainable light output.
