Low Voltage Vs. Line Voltage – Why Does The Difference Matter?

You might not be familiar with your home’s electric power. Still, it’s supplied in two ways: line and low. The main difference between these two types of electric power is the amount of electric potential or voltage. However, it’s crucial to understand how these two types of electric power differ and their advantages or disadvantages before choosing ‘electricians to work on your home.

If you’re a homeowner looking for electrical services or wondering about the pros and cons of low and line voltage, then you’re in the right place. In this blog post, we’ll go over everything you need to know about low voltage vs. line voltage. Continue reading!

Low Voltage

Safety Goes First

Before cleaning, turn off the power to your whole house fan; this way,

Low-voltage lighting systems usually use transformers to reduce the power delivered by line voltages of 120 or 277 volts. It’s an excellent solution when you need light in tight spaces that are difficult to access.


  • Safety: Low-voltage lighting is often used in landscape applications because the buried wires can be less costly than installing higher poles.
  • Energy saving potential: The key to saving energy with low voltage lighting is getting more out of your system than you put inside.


  • Potential of voltage drop: The power can be reduced by length, but not always without kinks along its run, reducing how much pressure gets through per second. 
  • Increased complexity for inspection: It’s important to stay on top of inspections and ensure your tenants follow all safety procedures, so you don’t get stuck paying damages later down the line.

you’ll ensure your hands or fingers don’t get caught by the fans. Your safety will always go first!

Use A Household Cleaner & Vacuum

Regular household cleaners and a microfiber cloth will be your best friend when it comes time to clean a whole house fan. A vacuum can come in handy for components like the motor or the exhaust vent.

Line Voltage

Line voltage is defined as the electric potential or pressure between two conductors. They use 120v or 277 volts to power the fixtures. Also, they don’t require transformers in many applications, so they’re a great choice for spaces with limited outlets like attics.


  • Cheaper fixtures: The fixtures are cheaper than those requiring a transformer, so that you can save some money upfront.
  • No maintenance: Once the system is installed, there’s no maintenance required since there are no transformers that can fail.


  • Less flexibility: Line voltage systems are not as flexible as low voltage systems because you’re limited where to put the fixtures.
  • More difficult to install: Line voltage systems are more difficult to install because you have to be careful not to overload the circuits.
