An energy-saving lighting fixture (100) includes a light transmissive tubular enclosure (70) including an inner tube (701) defining an inner compartment (71) therein, and an outer tube (702) disposed around and spaced apart from the inner tube (701) to define an outer compartment (72) therebetween. As such, the tubular enclosure (70) has a double-tube structure. A lamp assembly includes at least one lamp device (30), preferably a plurality of light emitting diodes (LED), disposed fixedly in the inner compartment (71) of the tubular enclosure (70). |
