Low Voltage vs Line Voltage—Why Does the Difference Matter?

The difference between the low and line voltage for the newbies in the electrical field might not be clear. So, to help you understand the two terms and their implementation in electrical settings, here’s the article.

Difference between Line Voltage and Low Voltage:

Below are the main differences between the two voltages types:

Overview

Line voltage is the regular voltage that flows through your home’s electrical cords without any transformation. The voltage in this situation is 120V. The line voltage can run all the appliances, lamps and bulbs normally.

The other voltage type is low voltage. In this type, a transformer is attached, bringing down the original voltage of 120 to 12. Recessed lights are usually the low voltage lighting in which this particular voltage type is used.

Cost

The line voltage fixtures are the typical fixture types without a transformer, so the cost of such appliances is not high. On the other hand, the low voltage uses the additional transformer, increasing the initial cost of the fixtures.

Size and style

In the line voltage, the fixtures are usually large with a regular enclosure for the normal-size bulbs. Besides, they also need to handle higher currents; thus, they are designed with larger in-built equipment.

However, in low voltage, the fixtures are usually compact, containing smaller light bulbs. Besides, various lighting fixture types are available that make it easier for users to create a narrow lighting beam or a wide flood light.

Lifespan:

The lifespan of the low-voltage fixtures is expected to be higher overall. However, there are transformers involved, which might get damaged or destroyed occasionally, creating problems. But overall, the light fixtures working on the line voltage might face technical issues much earlier than the low voltage fixtures.

Why does the difference matter?

Low and line voltage can impact your electricity cost and the initial spending on the light fixtures. So, it would help if you took the decision after analyzing these and the other differences that both voltage-oriented fixtures come with. Contact professional electricians for more details.
