The Least Efficient Light Bulb

What is the least efficient kind of light bulb?

The least efficient kind of light bulb is the incandescent bulb.

Understanding Efficiency of Light Bulbs

Efficiency of light bulbs refers to how effectively a light bulb converts electricity into light. The higher the efficiency, the less energy is wasted as heat, making the bulb more cost-effective to use.

Types of Light Bulbs

There are several types of light bulbs commonly used today, including incandescent bulbs, fluorescent bulbs, three-way bulbs, and frosted bulbs. Each type has its own characteristics in terms of efficiency and performance.

The Least Efficient Light Bulb

The least efficient kind of light bulb among the options given is the incandescent bulb. Incandescent bulbs are known for their low efficiency as they produce more heat than light. This inefficiency leads to higher energy costs and shorter lifespan compared to other types of light bulbs.
