Posted by Local Electrician Marrickville on 30 Jul 2025

When it comes to lighting your home, it’s important to know the various terms used for light bulbs and fixtures. Many people use both terms together, and this may create confusion when purchasing the correct bulbs or speaking with an electrician. We’ll explore the different names for fixtures and light bulbs, clarify common misconceptions, and provide the reason why it’s essential to be aware of these terms.

Common Names for Light Bulbs

There are a variety of terms used for light bulbs. Some of the most common are "lamp," "bulb," "incandescent," "fluorescent," and "LED." "Lamp" as well as "bulb" are commonly utilized interchangeably, but "lamp" typically refers to the whole light fixture, while "bulb" is the actual light source. "Incandescent" bulbs can be described as classic Edison-style bulbs that are gradually being eliminated in favour of more energy efficient alternatives. "Fluorescent" bulbs consist of tubes-shaped, long bulbs which are typically used in commercial settings, while "LED" bulbs are the most recent and energy-efficient option.

Terms used to describe various types of Light Fixtures

Apart from the different names for light bulbs, there’s also various terms used to define different kinds of light fixtures. "Can lights" are fixtures that are installed on the ceiling, while "pendant lights" are suspended from the ceiling using a chain or cord. "Chandeliers" are large decorative fixtures, which are typically located in dining rooms or in the entryway as well as "sconces" are fixtures mounted on the wall that provide ambient or task lighting.

Common Falsehoods

The most popular misconceptions is that it’s not possible to make use of the LED bulb in lighting fixtures which require incandescent bulbs. Although LED bulbs are different in wattage and shape requirements, there are many LED bulbs that can be utilized within existing lighting fixtures. Another misconception about fluorescents is the fact that they are harsh and unflattering, but there are many fluorescent bulbs that offer soft, warm light.

Why It’s Important to Know These Terms

Knowing the different terms used for light bulbs and fixtures is crucial for several reasons. It first ensures you’re using the correct bulbs for your fixtures. This will enhance the quality of your lighting and help you save money on your energy bills. It can also be helpful when communicating with an electrician who might need to know the specifics of your lighting fixtures to fix or upgrade them. Finally, knowing these terms will make shopping for bulbs a lot easier, since you’ll know exactly what you should look for when browsing in-store or on the internet.

Conclusion

Understanding the different terms used for fixtures and lights will make a huge difference when it comes to lighting your home.
