# Quick Answer: Do LED Lights Work On AC Or DC?

## Are LED Christmas lights AC or DC?

The typical white light LEDs need about 3-3.6V DC voltage to operate.

Typically those LEDs are wired in the similar way as the bulbs were, so that the light string can be powered with typically 24V voltage.

In this case the power needs to be DC..

## Will 12v AC LED run on DC?

There is no such thing as an AC LED. There is a circuit inside which probably incorporates a bridge rectifier and current limiting resistor. If so, it will work just fine on 12 volts DC. Yes, because LED’ s really are a Direct current device light that is hooked up to a circuit.

## How many amps does a 12 volt LED light use?

The LED’s seem pretty forgiving and I can run them at a reasonable brightness at anything between 8.3 and 12 volts. 8.3 volts draws 0.065 amps and 12 volts draws 0.65 volts.

## Do 12 volt LED lights get hot?

Some LED lamps can overheat when used on 12 or 24 volt solar systems. After a while the LEDs may start flickering or stop working entirely. … When LEDs are run at a higher voltage they become very hot. The heat can damage the LEDs, or the soldering around them, so they either start flickering, go dim or die entirely.

## How many amps does a LED light bulb use?

Consequently, how many amps does a LED bulb use? Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp.

## How long will a 12 volt battery run LED lights?

Also to know is, how long will a 12 volt battery run LED lights? 7 hours is 27% of 25.76 hours. You have 40 W total load; at 12 volts the current is 40/12 amps This is 3.33 amps; time to 100% discharge 85/3.33 = 25.5 hours approx. If you use 80% of the charge, that gives 0.8 x 25.5 hours which is 20.4 hours.

## How do you run LED lights on a 12 volt battery?

The cathode goes into the ground—it can be soldered directly to the negative port of the 12v battery. The anode should be wired into the on/off switch, which is then wired into the positive port of the battery. At this point, it is a good idea to check that the home lighting system works.

## Will LED lights work on DC power?

LEDs are usually considered to be DC devices, operating from a few volts of direct current. … To run an LED-based fixture from a mains supply (e.g. 120 V AC) requires electronics between the supply and the devices themselves to provide a DC voltage (e.g. 12 V DC) capable of driving several LEDs.

## What voltage do LED lights work on?

on LED datasheets. Typically, the forward voltage of an LED is between 1.8 and 3.3 volts. It varies by the color of the LED. A red LED typically drops around 1.7 to 2.0 volts, but since both voltage drop and light frequency increase with band gap, a blue LED may drop around 3 to 3.3 volts.

## How many LEDs can a 12v battery power?

So, a 12V battery wired to four 3V LEDs in series would distribute 3V to each of the LEDs. But that same 12V battery wired to four 3V LEDs in parallel would deliver the full 12V to each LED – enough to burn out the LEDs for sure! Wiring LEDs in parallel allows many LEDs to share just one low voltage power supply.

## How many amps do LED lights use?

When Dave connects incandescent bulbs to an amp meter, they draw up to 1.6 amps, but when LED lights are used, they only pull about . 26 amps.

## Can I connect a LED directly to a battery?

Five-volt LEDs can be connected to a nine-volt battery, but an external resistor is also needed in order to drop the voltage to the five volts required.
