Why Fluorescent Tube Light Is Considered Better Than Tungsten Filament Bulb ? |
|
Answer» Because, the efficiency of fluorescent TUBE is about 50 lumen / watt and whereas the efficiency of electric bulb is about 12 lumen / watt. Thus for the same amount of electric ENERGY consumed, the tube GIVES nearly four energy consumed, the tube gives nearly four times more light than the filament bulb.
