similar to normal incandescent light bulbs only hotter and brighter. [DOC] [TLE] Incandescent light bulb - Wikipedia [PAR] An incandescent light bulb, incandescent lamp or incandescent light globe is an 
electric light with a wire filament heated to such a high temperature that it glows 
with visible light (incandescence). The filament, heated by passing an electric 
current through it, is protected .... Thus they had low resistance and required very 
large conductors to supply... [DOC] [TLE] How light bulb is made - material, manufacture, history, used, parts ... [PAR] In 1802, Davy showed that electric currents could heat thin strips of metal to ... 
threadlike wire that offered high resistance to the passage of electric currents. ... 
This energy then strikes phosphors that coat the inside of the lamp, giving off 
visible light. ... One of the main components in a light bulb, the filament, is
