60W Vs 100W Light Bulb

When it comes to buying light bulbs, one of the most common dilemmas people face is whether to choose a 60W or a 100W bulb. While both options are widely available, they differ in terms of brightness, energy efficiency, and cost. In this article, we’ll compare 60W and 100W light bulbs to help you make an informed choice.

What is a watt?

Before we dive into the comparison, let’s first understand what a watt is. A watt is a unit of measurement that represents the amount of energy a light bulb consumes. The higher the wattage, the more energy the bulb uses. However, the amount of light or brightness a bulb produces is measured in lumens, not watts.

60W bulb

A 60W bulb consumes 60 watts of energy and, on average, produces around 800-850 lumens of light. This level of brightness is suitable for small rooms or areas where you want a cozy, ambient light. For example, you might use a 60W bulb in a living room or a bedroom – anywhere where you want to create a warm, intimate atmosphere.

One thing to keep in mind is that 60W bulbs can be less energy-efficient than their lower-wattage counterparts. If you use multiple 60W bulbs in your home, your energy bill could be higher than if you used lower-wattage alternatives.

100W bulb

A 100W bulb, on the other hand, consumes 100 watts of energy and typically produces around 1600 lumens of light. This level of brightness is much higher than a 60W bulb and is more suitable for larger rooms or areas where you need strong, bright illumination. For example, you might use a 100W bulb in a kitchen or a home office where you need to see things clearly.

In general, 100W bulbs are not as popular as they used to be due to their high energy consumption. Many people have switched to lower-wattage replacements, such as LED bulbs, which offer comparable brightness but consume much less energy.

LED vs incandescent bulbs

When making the choice between 60W and 100W bulbs, it’s worth considering the type of bulb you’ll be using. Incandescent bulbs, which are the traditional type of light bulb, use a filament to produce light. LED bulbs, on the other hand, use a semiconductor that produces light when electricity is passed through it.

In terms of energy efficiency, LED bulbs are far superior to incandescent bulbs. For example, a 60W incandescent bulb produces around 800 lumens of light and consumes 60 watts of energy, whereas a 10W LED bulb produces the same amount of light while consuming only a fraction of the energy. This means that by swapping out an incandescent bulb for an LED, you can significantly reduce your energy bill and carbon footprint.


Q: Can I replace a 60W bulb with a 100W bulb?

A: No, you should never replace a 60W bulb with a 100W bulb. Doing so can cause a fire hazard as the higher-wattage bulb could overheat and damage the socket or wiring.

Q: Which is more energy-efficient, a 60W or a 100W bulb?

A: A 60W bulb is generally more energy-efficient than a 100W bulb. However, when comparing energy efficiency, it’s important to consider LED bulbs over incandescent bulbs as they are more efficient.

Q: Are LED bulbs as bright as incandescent bulbs?

A: Yes, LED bulbs can be as bright as incandescent bulbs, but with much less energy consumption. Be sure to check the lumens rating to compare brightness, rather than wattage.

Q: Are 100W bulbs still allowed?

A: Yes, 100W bulbs are still available, but they are less common and may not be as energy-efficient as lower-wattage alternatives.
