The difference between 40w and 100w bulb is the amount of power they consume. Wattage is used to measure it.

• Wattage is the amount of power consumed by a bulb.

• Higher wattage bulbs consume more power and produce more light.

• Lower wattage bulbs consume less power and produce less light.

• Wattage is measured in watts (W).

CFLs are more energy-efficient than bulbs but have a lower rating due to their initial cost and mercury content.

• CFLs use 75% less energy than bulbs and last up to 10 times longer.

• CFLs are more expensive to purchase initially but save money in the long run.

• CFLs contain small amounts of mercury, which can be harmful if not disposed of properly.

• Bulbs are cheaper and easier to dispose of but use more energy and have a shorter lifespan.
