An improved incandescent lamp (112) and incandescent lighting system are disclosed, for projecting a beam of light with substantially improved energy efficiency. The incandescent lamp (112) includes a pair of reflective ceramic filament supports (118a, 118b) for supporting one or more filaments (116) in prescribed position (s) within an envelope (114) reflecting back substantially all visible and infrared light for incorporation into the projected beam or for absorption by the filament (s) (116). |
