tungsten-halogen lamp
Lamp that is brighter and lasts longer than a traditional incandescent lamp, but that lets off more heat.
base 
Metal end of a lightbulb inserted into a socket to connect it to the electric circuit.
electric circuit 
Lamp component allowing the electric current to circulate through the tungsten filament.

filament support 
Metal wire holding the filament.
bulb
