The Light bulb competition

Have you ever wondered how much energy does it take to light a bulb?  What is the difference between LED and tungsten bulbs?
Wouldn’t it be interesting to actually feel the difference between them?


It can be used in schools for the science lessons  where pupils try to light as many light bulbs as they can, ranging from LEDs to 60 Watt filament ones. Or at any event aiming to talk to people about energy conservation and how they can make a difference.
