You'll need a constant voltage power supply that can convert your household's AC voltage to a safe DC voltage. Finding the correct power source for your needs depends on several factors. First and foremost, we must secure the power we require from our power source.
To begin, calculate the wattage of your lamp. If you want to run multiple lights from a single power supply, add the wattages together to get the total wattage. Give yourself a 20% buffer over the total wattage you estimated from your LEDs to ensure you have a sufficiently sized power supply. By increasing your total wattage by 1.2 and then looking for a power supply rated for that wattage, you may easily achieve this.
When constructing an LED fixture or replacing a failing power supply, be sure the output voltage matches the LED voltage. LEDs with built-in current regulators will normally specify what input voltage to utilize. For example, because our LED flex strips demand 12V power, we would utilize a 12V power supply.
The amount of electricity that really goes into making the LED light-up is determined by the efficiency of a power supply. The higher the power supply's efficiency percentage, the more energy you'll save. Selecting a power source with an efficiency of at least 80% is recommended for LED applications. For the most efficient choice, look for Mean Far and Phihong power supplies, which have efficiency ratings well above 90%.

The efficiency of a LED power supply determines the amount of power to brighten the LED lights. A high-efficiency percentage saves more power. For LED applications, only choose an LED power supply with over 80% efficiency.
Power supplies work efficiently when used within their temperature range. All LED power supplies include safe operating temperature parameters. Ensure your environment is within the set temperature range to avoid power build-up and cooking of the power source.
The bigger the size of the LED power supply, the higher the power consumption. Ensure that your LED’s applications, e.g., the LED lighting strip are at least 20% less than the power supply’s rated wattage. For instance, if the LED trip requires 80 watts of power to run, you’ll need a power supply above 80 watts, which is at least 96 watts.

Determine how many watts your lamp will use. If you want to run more than one light from a single power supply, add the wattages together to get the total watts used. Give yourself a 20% buffer over the total wattage you calculate from your LEDs to ensure you have a large enough power supply.
When constructing a LED fixture or replacing a failed power supply, ensure the output voltage is compatible with the LED voltage. In most cases, LED products with built-in current regulators will specify the input voltage utilized.
The region and environment for the power supply is an important consideration when making your decision. When power supplies are within their temperature constraints, they are most efficient. A safe operating temperature range is critical in the power supply specifications.

Consumers should always consider the size of the LED when making their choice since the size of the LED directly correlates with the energy efficiency. The larger the LED, the more power it will take, so consider your priorities carefully. Do you care more about energy efficiency or larger LEDs? The general rule of thumb to ensure that the power supply does not overheat is to make sure that the total wattage of the LED lighting is at least 20% less than the power supply’s rated wattage.
Marilyn Gaskell, Founder of TruePeopleSearch, a US-based tech company.
Light-emitting diodes (LEDs) are a new generation of electronics that have replaced incandescent lights. It is no surprise that it has become a popular choice due to its energy efficiency, long life, design flexibility, and durability.
Here are just some factors to consider in choosing the right LED power supply:
Consider the location of the light as well as the surrounding area. Is it going to be used indoors or outside? In such circumstances, the environment is a big factor. It has the potential to modify the way energy is utilized, so you should carefully calculate the amount of wattage your LED light will require to avoid any energy loss.
Appropriate Wattage: Always add 20% to the total wattage you've calculated as a safety margin. For example, suppose you have a project with three LED strip runs (each requiring a power of 9 watts). There would be a total power supply of 27 WATT. Simply multiplying 27 by 1.2 gives a 20% cushion.
Voltage: Make sure the power source you choose for your LED strips, bulbs, or applicators can handle the input voltage supply. Line voltage fluctuates depending on the country you live in. Knowing if you have a low or high line AC power is a good starting point. This will allow you to determine whether your power source is properly matched to the line power in your location.
If your LEDs are dimmable and you want to control their brightness, make sure you get a power source that can dim them. Power supply specifications should state whether or not the power source is dimmable, as well as the type of dimmer control it employs. Nora Ava, Electrical Account Manager at Home Alliance
