How Many Strings of Led Lights Can Be Together

Christmas is a time of year where millions of people worldwide come together to celebrate. Families get together, share gifts, and enjoy each other’s company.


However, while Christmas is generally a happy time, it can also be expensive. One way to reduce the cost of Christmas is to make some of your decorations yourself.

In this blog post, we will be discussing how many strings of led lights can be together. We will also provide tips on making your Christmas decorations look professional. Stay tuned!

Summary: The number of LED light strings that can be safely connected together depends on the specific type of lights being used, as well as the power source and the capacity of the fuses in the light strings. Typically, LED lights have lower power consumption compared to traditional incandescent lights, allowing more strings to be connected together without overloading the circuit.

To determine the maximum number of LED light strings that can be connected, consult the manufacturer’s guidelines or the packaging, which usually provide information on the recommended limits for a particular product. Additionally, consider the total wattage of the connected strings and ensure it does not exceed the capacity of the power source or the fuse.

Exceeding the recommended limits can result in poor performance, increased risk of electrical hazards, or even damage to the lights. By adhering to the manufacturer’s guidelines and considering power consumption and capacity, users can safely connect multiple LED light strings for various decorative or functional purposes.

10 Ways to Tell How Many Strings of Led Lights Can Be Together

1. Count the Number of Conductors:

You can count the number of conductors that come out of each string and then add them up, but this doesn’t always work because you might have a string with just two conductors, which might be broken down into 30 of those strings.

2. Multiply the Length of the String by Circuits:

You could find out how long each string is and then multiply that length by however many circuits there are on it, but this is only useful if you know what the length of each string is.

3. Look for a Lighting Fact Label:

A lighting fact label is placed on the string or packaging that tells how many circuits there are, the maximum wattage load, and how long it can safely be if wrapped around a tree.

4. Calculate Wire Capacity:

The wire capacity of the string is calculated by multiplying the total number of watts by 1.25 and then dividing that number by 12 volts.


This should be printed on a lighting fact label; if not it can be found in the owner’s manual for each set.

5. Check the Amperage Rating on Each Circuit:

To find out how many circuits you can hook up to a string of lights, multiply the number of amperes for each string by 1728 (the number of watts a typical incandescent light bulb uses) and divide by 12 volts.

If this number is less than or equal to the total wattage of the string, you can hook up as many strings as will fit on a single outlet.

6. Compare Watts Per Circuit:

The typical Christmas lights use about 4 watts per circuit. If there are four circuits on a string and the total wattage is 16, you can connect four strings. If there are five circuits with a total of 20 watts, you can hook up five strings.

7. Count the Number of LEDs:

One way to tell how many strings of lights you can hook up is to count the number of LEDs in a single string.

For example, if there are 20 LEDs in a single strand and you have a set of lights with a total of 300, you can hook up 20 sets.

8. Determine if it is Series or Parallel:

If the lights are hooked up in a series circuit, you can add up all of the LED amps for each string and then add them together. Series circuits have one power supply from which strings get their voltage.


Parallel circuits have multiple power supplies that the strings switch back and forth between to produce a specific wattage load.

9. Read the Label:

If there is no lighting fact label on the lights, you can find out how many circuits there are by reading the label on the string.

Look for the number of watts per circuit, the maximum wattage for each string, and how long it can safely be wrapped around a tree.

10. Look at the Power Adapter:

If there is no lighting fact label on the set of lights or its packaging, you can look at the power adapter to see how many amps are required to power the string safely.

For example, if the string has a 12 or 14.4 volts AC adapter, two amps are being used to power it, and you can hook up as many strings as will fit on a single outlet.

The Different Types of Led String Lights

1. Outdoor Led String Lights

This is a long-lasting type of light strand great for outdoor use. In addition, these strands come weatherproof and are made to be highly durable.

This strand of lights is the best type to use for parties, weddings, or even general outdoor lighting.

2. Indoor Led String Lights

This type of string light is usually not as durable as the outdoor type, but it can be great for indoor use.


It comes in various lengths and color choices, so you’re sure to find one that meets your needs. This type is especially great for decorating weddings, restaurants, and other events.

3. C7 Led String Lights

This is another durable string light strand perfect for indoor or outdoor use. However, its durability is also much bigger than the other types mentioned, which gives you more space to work with. These lights are not meant for small spaces or thin poles.

4. Micro Mini Lights

This type of string light is tiny and thin. You can use these lights on basically anything you want since they’re that thin, but the downfall to this strand is how fragile it is. One bump or break and your entire strand could be ruined.

5. Fairy Lights

This is a small string light strand of lights. Typically, fairy lights are used as accent lighting and decorating around the house.

They’re thin and perfect for all kinds of applications, but they aren’t meant to be left on for long periods. They can also be a little fragile due to their size so take care when stringing them up.

How Many Can Lawn Lights Be Connected in Series?

There is no official maximum number of Led Lawn Lights connected in series. Theoretically, there is no limit to how many lights you could connect in a string.

If one light does not work or malfunctions, the rest will continue running because they are wired in parallel.

However, an excessively long string might get hot and burn out, so you should limit your run length to 50 lights if possible.

What Is the Maximum Amount of Yards That Can Be Covered Using One Mini String?

One mini string, which is 10 feet long, can cover up to 6 yards. The maximum number of mini strings used in one project will depend on how many lights you want to use per yard and how much spacing you would like between each string.


You can use one mini string every six feet with no spacing as a general rule. However, if you want to space the lights more closely together and light up more of your yard, you can use one mini string about every three feet.

You will need to experiment before beginning your project and see what provides the look you’re seeking.

What Is a Wire to a String of Lights?

The wire that connects a string of lights is called a lead. The number on the label found on the strand indicates the number of amps being used to power it.

This number should be between 2 and 50, with anything above 50 requiring its circuit box. How many strings you can hook up on a single outlet depends on the number of amps being used by each string.

For example, if two strings are powered with 2-amp supplies, you can use as many as fit on an outlet.

However, if one of the strings uses 50 amps or more, you may not be able to hook up that many lights due to wiring and circuit protection limitations.

Frequently Asked Questions(FAQ):

Generally, there is no set distance between each string on outdoor strands of lights. However, you should try to keep your spacing between strings about 12 inches apart if possible.

Too much space between the strings may cause issues for some applications, so it’s best to keep the spacing as close together as possible.

As a general guide, each separate set of lawn lights or sets that have been interconnected will require one transformer for every 100 LEDs.

This does not mean connecting one string of lights to 1 transformer; this is just the manufacturer’s guide.

It is best to create a test system for your project and ensure that nothing overheats or blows before installing.

This is an excellent question. A wattage chart may be beneficial in determining the total number of lights it’s safe to string together.

However, they are typically specific to one type or another of lamp shapes and sizes.

Some lamps burn brighter than others per wattage, so it’s best to find an average in your area for what’s familiar when it comes to wattage used.

Remember that these are not exact numbers but should give you a broad estimate of what you’ll be working with.


As you can see, there is no hard and fast rule for how many strings of led lights can be together. It all depends on the design’s purpose or what effect you’re looking to achieve.

The more strands used in a single space usually mean higher energy consumption when it comes to lighting your event with LED string lights. But if this doesn’t matter to you, then go ahead and enjoy yourself!
