Which power supply do I need for LED lights?

Which power supply do I need for LED lights?

Make sure the total wattage of your LED strip lighting is at least 20 percent less than the power supply’s rated wattage. For example, if you have an LED strip light that requires 80 watts of power to run, you’ll need a power supply that’s rated for at least 96 watts.

Do LED lights need AC or DC?

In most applications, LEDs are driven by a DC power supply, but AC offers several significant advantages. Lynk Labs has developed technology that allows LEDs to be driven directly from an AC supply. LEDs are usually considered to be DC devices, operating from a few volts of direct current.

Can I use any power supply for LED lights?

LED strips, unfortunately, are not as simple as traditional incandescent light bulbs when it comes to installation and set up. Because they run on low voltage DC, they require a power supply device that converts 120V/240V AC (depending on your location) into the voltage signal that LED strips can use.

Do LED lights run on DC power?

In most applications LEDs are driven by a DC power supply. LEDs consume DC current to produce light; with AC current the LED will only be lit when current flow is in the proper direction. AC applied to an LED will cause it to blink on and off, and at high frequency the LED will appear to be lit continuously.

Can you run 12V LED lights on 18v?

LEDs don’t required much. If the input to the step down converter is less than the output voltage, it just won’t work. If your input is 9 to 10 volts, and you need 12 volts, then you need a step up converter.

Do I need a transformer for LED lights?

All mains powered LED bulbs require a transformer. Depending on the bulb type, the transformer/driver may be built in to the bulb casing or may be located externally. The purpose of the transformer is to reduce mains voltage (240V) to the desired level relative to the bulb being powered (e.g. 12V or 24V).

Can LED lights run on 12V AC?

Yes, because LED’ s really are a Direct current device light that is hooked up to a circuit. When looking at the circuit there is the 12 volt DC battery, a switch, and the LED. LEDs are DC devices. An AC LED simply adds a rectifier for the AC (plus some other gubbins to set the current and ‘smooth’ the rectified AC).
