Thomas Edison's first lightbulb was about 20 watts
Thomas Edison's first successful light bulb lasted for about 13.5 hours when he first demonstrated it. However, he and his team later improved the design to last for over 1500 hours.
A 60 watt light bulb is a light bulb with 60 watts capacity. When talking about watts, you're talking about the power that is transferred from the appliance to the accessories. Therefore, the light bulb labeled "60 watts" takes 60 watts to light up. A 60 watt light bulb will not be as bright as a 120 watt light bulb.
No, the first light bulb that Thomas Edison invented is not still operational. Over time, light bulbs burn out and lose their ability to produce light due to the filament burning out. However, Edison's invention laid the foundation for modern lighting technology.
The 100W light bulb is brighter than the 60W light bulb. The difference in brightness is 40 watts.
A light bulb with a power consumption of 150 watts typically produces around 2600 to 3000 lumens.
