A Constant Voltage LED Driver 12V & 24v can be used to power LED lights that have constant current drivers already within the system or resistors . 'Constant voltage' refers to the ability to fluctuate output current to maintain a set voltage. So you need some type of constant voltage power supply that can convert your AC household voltage down to a safe DC voltage. There are many things that factor into finding the right power supply for your needs.

To get started, find out how many watts your light will consume. If you hope to run more than one light off of one power supply, you must sum the wattages up to find the total watts used. Make sure to have a large enough power supply by giving yourself a 20% cushion over the total wattage you calculate from your LEDs.

It is important to first verify that the output voltage is compatible with the LEDs voltage when building an LED fixture or replacing a bad SMPS LED Driver. LED products with built in current regulators will usually be pretty good about specifying what input voltage should be used.

Also, be sure to make sure the power supply you select can handle the input power you have. Line voltage will change depending where you are in the world. Make sure you know whether you have low-line AC power (100-135VAC) or high-line AC power (170-265VAC). A lot of power supplies, such as Smarts Electronics products, will be rated for the full range but it is always helpful to know your AC input and make sure that the Dimmable LED Transformer you use is suited for this.

Also, IP rating, dimming function, size of the LED Lamp Driver are also the factors we should take into consideration.
