Why Does the Difference Between Low Voltage and Line Voltage Matter?

While lower voltage lighting can save you money and be used for accent or other non-primary lighting options, the standard voltage for your home’s lighting is 120 volts. Your overall energy costs may go down due to this decreased energy requirement.

What Is Low-Voltage Lighting?

Why Does the Difference Between Low Voltage and Line Voltage Matter?
Even though line voltage is the norm, low-voltage lighting is frequently used in some situations. Low voltage lighting typically uses voltages between 12 and 24 volts. You’ll need to install a specific transformer to regulate the flow if you want to reduce your ordinary voltage to these levels. Unique fixtures are unnecessary for low voltage electrical systems because the transformer will regulate the level correctly. Low voltage lights are also available with built-in transformers to connect to a line voltage circuit. Your electrical panel can be upgraded, and Power Source Electrical can guarantee that your low-voltage transformer is installed correctly.

What Is Lighting at Line Voltage?

Line voltage, typically 120 volts, is the typical voltage of the circuits in your home. You often use wall outlets in your home to run your TV, charge your phone, and plug in your toaster are often all 120v. 120-volt circuits are used for standard illumination. Although 120v is the most common voltage, 277v, or “line voltage,” is also occasionally used. While some homes are wired to have a greater voltage, line voltage refers to the standard voltage found throughout your home. Since every home will have a separate electrical system, there is no standard “line voltage.”

Benefits And Drawbacks Of Low-Voltage Lighting

Low-voltage lights are more prevalent among households since they use less energy and are less expensive to buy. The desired function of the lights, the fixture’s position, the load requirements, and whether you intend to move the fixture in the future are other elements that will influence which is preferable.

Low-voltage lighting has several benefits, including:

Savings In Energy

The majority of folks are drawn to this one. Low-voltage lights use less electricity. Therefore running them will cost less money.


Line voltage systems are more challenging to relocate than low voltage lighting. Low-voltage outdoor lighting is widely used as a result of this. Low-voltage wiring can be moved more easily since electrical codes do not mandate that lower voltage wires be buried and run through conduits, metal, or plastic tubes that protect wires.


Your risk of electrocution is reduced at a lower voltage. As a result, lower voltage lighting can be ideal for gardens because line electricity could be damaged if it were mistakenly severed.

Low-voltage lights, particularly for outdoor illumination, have many benefits, but they aren’t flawless. A few disadvantages of low-voltage lighting include:

The Complexity Of Maintenance And Inspection

Finding expert assistance for installing, inspecting, and maintaining low-voltage systems could be challenging due to their rarity, mainly when dealing with the transformer that makes low-voltage systems functional.

Limited Capacity For Loads

Your low-voltage system will have less capacity than a line-voltage system since it is connected to a transformer. If you plan correctly, this might not be a problem, but adding more lighting to your electrical system could be problematic.

Low Voltage

Low-voltage systems filter through a transformer, which could result in a less dependable connection than a line system. A voltage drop happens when your circuit is overworked, similar to the restricted load capacity issue. Your circuits can be considered a hose; low water pressure will result in less water and lower voltage flowing through the hose’s end.

Why Do My Outdoor Low-Voltage Lights Blink?

Flickering lights can be brought on by voltage loss and a constrained load capacity. The lights will flicker if there is a problem with the transformer since insufficient power will reach them. Fortunately, this modest power flow shouldn’t harm LEDs, but you won’t get the full advantage of lighting you desire. Voltage drop happens when your circuit has too many devices and a high enough current drain. It’s crucial to avoid overloading your circuit to prevent flickering.

Looking For Electrician?

Please don’t attempt to install low-voltage lighting in your home by yourself, indoor or outdoor. For an untrained person, installing the transformer can be perilous. Your Power Source Electrical certified electricians can advise you on the ideal places for low-voltage electrical systems in your house and safely install them so you can enjoy the benefits without worrying. Make an appointment or call us to find out how we can assist you with your low-voltage electrical work.
