Are Christmas lights AC or DC?
In Christmas lights, both AC and DC currents are used depending on what kind of lights are being used. Some lights use AC currents, and some lights use DC currents. In DC currents, electrons flow through one end of the bulb, and out the other end. When turned on, a DC electric current has a steady flow of electricity.
Will Christmas lights work on DC power?
Normal Christmas lights will run off of a 120 volt DC source just as well as an AC source because they are a resistive load.
How many LEDs can a 12V battery power?
The answer should be the source voltage divided by the voltage drop of 1 LED. So if your source is 12v, and your LEDs have a voltage drop of 3.5, 12/3.5v, gives you 3 LEDs.
How many mini Christmas lights can be on a circuit?
Different sizes and types have different wattage, affecting the number of lights you can put on a single circuit. For example, say a string of small LED lights only uses 12 watts. So you could, put 105 strings of those lights on a single circuit (1440÷12=105).

How many bulbs are in a 100 count Christmas light?
Most of the time strands of Christmas lights are wired in 50 bulb groups. So, a 100 count strand "usually" has two groups of 50 bulbs. However, I've also seen 3.5 V bulbs which use groupings of 35 bulbs. The best way to estimate the voltage you need is to divide 120 by the number of bulbs in the garland.
Do Christmas lights have a control box?
I've not seen many strings of christmas lights with a "control box". Most mini bulbs are wired in series and just plug in.#N#Most modern mini bulbs contain a bypass shunt so the whole string doesn't go out if a bulb goes out. But Red Squirrel's analysis is correct, the caveat being that the rest of the bulbs see a higher voltage if one does burn out. If you don't replace the burned out bulb, it can cause the whole string to fail in a cascade of burned out bulbs.#N#Anyway, why don't you just count the number of bulbs in your string instead of guessing? But yes, those are standard bulbs.
How many watts does a Christmas light use?
For example, a 2-meter string of about 70 LED lights uses only four watts altogether, while on the other hand, one normal Christmas light uses 5 watts all by itself. Doityourself Staff.

What happens if you remove a 50 strand bulb?
If you remove one of the bulbs, its 50-bulb strand will go out, but the remaining strands will be unaffected. If you look at a strand wired like this, you will see that there is a third wire running along the strand, either from the plug or from the first bulb. This wire provides the parallel connection down the line.
Does adding two extra lights to a 50 strand light bulb matter?
Adding the two extras dims the set imperceptibly, so it doesn't matter. The lights in a 50-bulb strand are wired like this: You can now see why mini-light strands are so sensitive to the removal of one bulb. It breaks the circuit, so none of the bulbs can light!

What happens when you plug in Christmas lights?
This means that whenever you plug your Christmas lights into the wall they are sharing that circuit's capacity with anything else that may also be drawing power. If very few things are on the circuit you have more wattage capacity. However, if your circuit already has a number of items drawing power from it, you may begin "tripping your breakers" in the fuse box. This happens when your wattage exceeds the amp capacity of the circuit.
