ABSTRACT:
A low-wattage, bi-helically shaped, compact fluorescent lamp, having preferably a wattage rating of preferably 23-watts, to sustain constant luminous output when the lamp is mounted in either in an upright position or mounted lying in the horizontal plane, by the unique placement of two cooling point chambers on the periphery of the bi-helical lamp. In an alternative embodiment, a medium wattage compact fluorescent lamp performs ideally by using three cooling points chambers, whereas higher wattage sized lamps perform best utilizing preferably four to five cooling point chambers. Hence, the plurality of cooling point chambers required for omni-directional mounting of the lamp is functional with the physical size of the lamp, its wattage rating, the quantity of mercury needed and the placement of each cooling point chamber.
