How Many LED Lights Can Go on a 15-Amp Circuit?

LED lights are an excellent substitute for traditional bulbs for your home. They use less wattage and are more energy efficient, which can help you save money. They can also prevent issues with your system when you overload.

The number of LED lights you can put on a 15-amp circuit depends on the wattage of the bulbs and how many other devices are connected to it simultaneously. 

For instance, you can use up to 1440 watts if there is no other plugged light. It means that you can have up to 14 lights that are each 100W and 22 65W.

This post will elaborate more on this topic, so read on.

How Many Lights Can I Put on a 15-Amp Circuit?

To determine how many lights can be on a single 15-amp circuit, we need to know the capacity of the circuit. For instance, we want to work with a circuit that’s 15 amps and one that’s working under 120 volts. We can get a total of 1800W from this type of circuit.

We can still use the same idea even if we use a different circuit type. For instance, if we use an amp with a potential difference of 120 volts, we can put about 2,400 Watts on it.

Before we can start calculating the amount of power you should put onto a circuit, we need to know what the amp of the same type of circuit is.

For a circuit to be safe and secure, you should put in the maximum power you can use. For instance, if you have a 15-amp circuit, you should put up to 1800 watts on it.

However, most electrical engineers recommend using only 80% of it. Doing so will help minimize the risk of power surges and make the circuit more secure.

How Many LED Lights Can Go on a 15 Amp Circuit?

This stage will involve figuring out how many lights would fit in an open circuit. In most homes, there is usually a switch that has light bulbs connected to it.

If you have a 15-amp circuit, you might want to consider adding a plug to it. Before you start working on a new circuit, you must know how much room for the lights.

Before calculating the number of lights that will fit into a circuit, you must consider the energy consumption of the other appliances and devices in the circuit. For instance, if you’re using an LED light, you can switch it on to measure the energy it uses.

After doing this, you can open the electric panel and switch all the circuits until you find the one you want to measure.

One of the most practical steps is identifying which appliances and lights connect to the circuit. You can then estimate how much energy you use off that circuit. For instance, if you have three devices that need 400 watts, you only have to use 240 watts to get the lights on.

What Happens if I Plug Too Much Into a Circuit?

There are many reasons you should only use a certain number of LED lights in your home’s circuit. One of the crucial ones is to keep it safe and secure. When the power is used to overload the circuit, it can cause various issues and even cause a fire.

If you try to connect more than the number of devices and bulbs required to the same circuit, the whole system will overload. It can cause the appliances connected to the circuit to stop working. Sometimes, it can also lead to a fire or an explosion.

How Many LED Lights Can You Use Simultaneously?

LED lights are more energy-saving than traditional bulbs. They can save you money and reduce your energy consumption by up to 80%.

One of the critical things you should consider when choosing LED lights is the number of amps it can use. Knowing how many amps are in your circuit will allow you to plug in the right amount of lights without making any problems.

If you are smart about your energy consumption, adding LED lights to your home is easy. Follow the suggestions in this post to ensure you are always safe using them.

What Factors Should You Remember When Adding Lights to a Circuit?

You can incorporate as many outlets as you want into a 15-amp circuit, but you have to restrict the number of appliances you plug in. If you exceed the rating, the breaker will stop working.

For powerful appliances, such as heaters, it’s essential to use circuits with the fewest outlets. It will prevent you from overpowering them.

Sometimes, homeowners can put lights and outlets on the same circuit. This method works because the lights draw very little power. It will enable you to distribute the power consumption of your electrical panel.

You should consider using dedicated circuits for powerful appliances like washing machines. These can be placed on separate circuits to prevent them from competing with other instruments.

Instead of concentrating your outlets in one location, distribute them throughout the house. It will allow you to access electricity quickly. Power extensions and power strips are not ideal short-term solutions. They can pose various hazards.

Frequently Asked Questions

How Many LED Shop Lights Can Be On One Circuit?

You can safely have 12 LED lights on one circuit simultaneously. However, it has a few exceptions, such as using lights with a lower wattage. Having 12 lights on a single circuit can help prevent overload and other issues with your breaker box.

Sometimes, you can add a few more LED lights to your circuit. It is only possible if you have approval from your local inspectors and have the necessary information about the devices.

With LED lights, you can add as many as you want as long as the load doesn’t exceed 80%. However, since most homeowners don’t know how these lights work, it is best to limit the number of these lights to 12.

How Many Lights Can Be On One Switch?

You can have as many lights in one switch. You can use one switch to control multiple lights. There are two ways to do this, one is by connecting the lights, and the other is by joining the switch to the first fixture.

One of the easiest ways to have all of your lights switch is through a configuration known as “home run.” This method allows you to disconnect the fixtures that you no longer need.

What Happens if I Overload a Circuit?

If you plan on putting LED lights all over a single circuit, it could cause some issues with the electricity in your home. The circuits in your house can handle a certain amount of electricity, which can overload if you connect them to an unbearable number of outlets and lights.

If you overload a circuit by adding too many electrical components, it could cause it to malfunction. We generally recommend that you only simultaneously put 12 lights on a single circuit. However, if you overload 20, it could cause some problems.


You can use a 15-amp circuit to light up your home using LED lights. The wattage of the bulbs and the number of devices connected affect the number of lights you can put out.

If you have no other plug-in light, you can use up to 1440W of power if you have no different plug-in light. It means you can have up to 14 LED lights capable of producing 22 and 100W.
