<p>A low pressure gas discharge lamp (30) is provided with a pair of high power incandescent electrodes (32, 34) to increase output illumination at the lamp ends. In one embodiment, these electrodes are also used to enable the gas discharge. In an alternative construction, the electrodes are of high power and low emissivity and are electrically connected to a second pair of high emissivity electrodes (36,38) which provide the means for enabling the gas discharge. With this second construction, the low emissivity electrodes can act as ballast for the circuit.</p> |
