There is no doubt that we are literally surrounded by LED lights! They are present in houses, schools offices, and on the streets. Colorful, bright and save energy.

Many people find selecting the right power supply to be confusing This time, we will provide you with information on the LED power supply types: constant voltage and constant current. We will be helping you understand how to choose the right Nanhai power supply for your LED lights so that they (both items) can give extensive working together. Nanhai is here to help you.
What is a Power Supply?
Before we go further, it is important to understand what a power supply stand for. A LED power supply is a unique device that sources electricity from somewhere like an wall outlet, then alters it to the correct voltage and current required by LED lights. Like a bridge which transfers electricity from your house to the LED lights ensuring that it receives same amount of power as needed in order for them to shine.
There Are 2 Types of LED Power Supplies
This power supply is a constant voltage and delivers an uninterrupted 12v to the LED light. That is what the voltage remains constant at all times. But, its current (electricity flowing through) can and will differ based on the resistance rating of that LED. This type, however simpler and usually cheaper, is rather popular.
Constant Current: It is a power supply that sends a continuous current to your LED light. It has no load hence it does nothing in regards to as just being an electricity bridge between the conductor lines, which means there is a constant flow but maybe where voltage literature on what LED requires at that moment changes. Since the constant current supplies emitter is much more efficient and brightness control of LED light-ground.
What's the Difference?
The way a constant current power supply like waterproof 12v power supply controls the electricity flowing to an LED is fundamentally different than with a constant voltage power supply. Ease-of-use constant voltage supplies], conserve much more resources adapting_constant_voltage_power_sources But they wont scale as well down the road if you want to have a that many LEDs working at once.
In contrast, constant current sources can be a bit more costly and require some extra work to rig up. They cannot really control the voltage from one LED to another, like LEDs spec sheets do. But they are better at giving each electrically different led enough volts to shine. Particularly critical if you need brightness to be the same for multiple LEDs.
Selecting a Good Quality LED Driver
One thing you will do well to keep in mind is the needs of your LED light which you are choosing an LED power supply and LED driver power supply for. Find the voltage and current requirements specifically. This information is often provides with the LED label, or can also be found in included instructions. When you have this information, then pick a Nanhai power supply which has the same specifications.
The other is that why not stress where you are about to place the LED. PT 4: Choose the Right Power Supply for your LED If you place the similar warm light in a wet location or on environments where it experienced harshness, then sure that also requires an appropriate type of power supply to handle. Nanhai is good at such kind of tough environment power supply like their IP67 rated supplies that can protect moisture and dust.
Power supplies: pros and cons
Below we will break down the benefits and shortcomings of each power supply:
Constant Voltage Supplies: provide generally lower-cost, easy to use and common power supplies. These suit most of the cases that arise. But driving multiple LEDs at the same time may not be as efficient for them. The voltage output of your power supply may be unable to precisely regulate the current being fed into each one of these if you try using LEDs that have varying resistances.
Constant Current Supplies – This type of power supply is generally a better solution giving greater efficiency and more control over current and therefore brightness. They are most commonly used when chaining many LEDs together to make sure all of the LEDs share equal current. Although it is not impossible, though they do tend to run a little pricey and be more of an installation headache than the constant voltage supplies.
Check Your LEDs
The second point in choosing a Nanhai LED power supply is the efficiency of the power source. Power supplies could be inefficient and waste energy, as well as adding to heat. The surplus heat will cut down the lifespan of a LED light. If the power source is wrong, it may shorten or even never light up as required by LED.
The LED lights will work at their best capacity and additionally they are also guaranteed to last for a long time when you pick the right Nanhai Led Power Supply. Nanhai provides a wide range of power supplies that are designed to meet all needs, both constant voltage and constant current.
