what is the difference between 60 and 100 watt bulbs?
So a 100W incandescent bulb converts electricity at say 100VAC and 10Amps into light and heat. And a 60W incandescent bulb converts electricity at 100VAC and 6 Amps into light and heat. The 100W bulb will generate almost twice the amount of light than the 60W bulb. It will also generate about twice the heat.
