You will need a device to limit the amount of current reaching to your LED to protect it from overheating. These devices can be a driver or a resistor. If you do not regulate the current, LED can draw up much current than it is designed for. This can even lead to failure of your LED light.
In this article, we will discuss some tips and tricks that will help you choose your next LED Power Supply.
First thing first, find out how many watts your light will be consuming. If you need more than one LED you can sum up the watts of individual LEDs.
Now add more 20% to the total number of watts you calculated. This is to make sure that your LED does not get overheated easily. This can be done very easily. Just multiply your total calculated watts with 1.2. Now you can find a power supply as per the final calculated watt.
Let us take an example, you have 4 LED strips that consume 12 watts each. So, you have 12*4=48. So your total watt is 48 watts. Now add 1.2*48=57.6. So you are going to find a power of approximately 60 watts.
Before you build an LED fixture, you must find out whether or not the output voltage is compatible with the voltage of the LED. Using LED products that can regulate the current itself is very useful. In our example above, we would need a 12V power.
Another thing to consider is to make sure that the power supply, you are choosing can effectively handle the input power at your home. Line voltage can change depending on where you are living. It is important to know if you are living in an area of low-line power (90-120V) or high-line power (200-240V).
