How to Choose Your LED Power Supply?

You will require a device to limit the amount of present reaching to your LED to protect it from overheating. These devices can be a car owner or a resistor. If you do not regulate the current, LED can draw up much present than it is designed for. This can also lead to failure of your LED gentle.

In this article, we will discuss some tips and tricks that will help you choose your next LED Power.


First thing first, find out how numerous watts your light will be eating. If you need more than one LED you can sum up the watts of individual LEDs.

Now add more 20% towards the total number of watts you determined. This is to make sure that your LED will not get overheated easily. This can be carried out very easily. Just multiply your total calculated watts with 1 . 2 . Now you can find a power supply as per the ultimate calculated watt.

Let us take a good example, you have 4 LED strips that will consume 12 watts each. So , you have 12*4=48. So your total watt is 48 watts. Now include 1 . 2*48=57. 6. So you are likely to find a power of approximately 60 w.


Before you build an BROUGHT 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 helpful. In our example above, we would require a 12V power.

Another thing to consider is to make sure that the power supply, you are selecting can effectively handle the insight 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).

Dimmable LED

If you are using dimmable LEDs whose brightness can be adjusted make sure the power you choose should also have got adjusting characteristic. You should go through the specifications and find out if your power supply is dimmable or not.

PWM Dimming: The characteristic of this dimming modulation is that they can be used in any power supply. Moreover, the supplies that do not mention “dimmable” may also be dimmed using these.

TRIAC Dimming: In this instance, you would need standard dimmers to manage the power.

Temperature and Weather

A single important thing to consider while choosing your own power supply is the location and atmosphere it would be used in.

They perform best when they are used within the specified temperatures range as per their specifications. The surroundings and weather are also responsible for the effective performance.

The power supplies can also be provided with an IP rating or even ingress-protection rating. This rating identifies the size of solid and the pressure associated with liquid that it can withstand.
