<p>A low-wattage fluorescent lamp (10) is provided. The lamp (10) has at least one mercury cold spot region (30) effective to maintain the mercury in the lamp at less than 30°C, preferably 25°C, in an enclosed lamp fixture. The lamp (10) also features a reduced distance between electrodes (17) resulting in less power being required to sustain an electric arc discharge during operation of the lamp (10). The lower power electric arc generates less heat to raise the temperature of mercury vapor within the lamp (10).</p> |
