How many amps does a string of incandescent Christmas lights use?
Since each string is 40.8 watts, we know that each string needs 0.34 amps (40.8÷120). Five of those together is 1.7 amps. The power strip has 6 plugs on it. 1.7 x 6 = 10.2 amps.
How many amps are Christmas lights?
Lighting circuits (which often include outlets) typically are 15-amp. The amp rating tells you how many lights and other devices the circuit can handle without tripping its circuit breaker.
How many amps does 100 LED Christmas lights use?
Based on these calculations, the 100 ft section of the C9 light line would draw 6.09 amps. By repeating these calculations for all your Christmas lights, you’ll be able to determine how many sets, or how many feet of light line you can plug into specific power cords or outlets.
How many Christmas lights can you have on a 20 amp circuit?
For a 20-watt strand, that’s 10.5 string lights connected in series. Don’t forget to sum the wattage you’re plugging into each outlet on the circuit, making sure not to exceed maximum wattage (1,440/1,920).
How many amps is 100 mini lights?
15.3 amps
Christmas Light Specifications
| (99) 35-lite miniature light set = 16.06 amps | [(99 x 35) x .51 watts per bulb/110] = 16.06 amps |
|---|---|
| (33) 100-lite miniature light set = 15.3 amps | [(33 x 100) x .51 watts per bulb/110] = 15.3 amps |
| (200) C7-7 watt light set = 12.72 amps | [200 x 7 watts per bulb/110] = 12.72 amps |
How much power does a string of Christmas lights use?
A string of 25 incandescent C9 bulbs — the big plump ones often used outdoors — uses 175 watts of electricity, which works out to a whopping $15.12 to run over a season (assuming 12-hour-a-day operation for 45 days).
What size breaker do I need for Christmas lights?
Short Answer: For a 20-amp breaker don’t exceed 1900 watts if it is dedicated to only Christmas lights. For a 15-amp breaker, don’t exceed 1400 watts. Keep in mind that if the circuit is shared, these numbers must be modified.
Can you plug incandescent bulbs with LED bulbs?
DON’T connect Incandescent and LED mini light strings together The logic behind this advice is based on the amount of the electrical current. Incandescent light strings require a larger power current than LED strings. It is better to keep the LEDs and incandescents separate, running each out of a different outlet.
How much electricity do LED Christmas lights use?
How Many Watts do Christmas Lights Use?
| Bulb Type | Wattage per Bulb | Cost of Powering 10, 100-bulb strands (at avg. $0.12/kWh)* |
|---|---|---|
| Incandescent C7 (2”) light | 5 | $126.00 |
| Incandescent C9 (3”) light | 7 | $176.40 |
| LED mini light | .07 | $1.76 |
| LED C9 (3”) light | .09 | $2.27 |
What happens if you plug in too many Christmas lights?
Because light strings have a maximum wattage capacity, which is why many string lights come with a little fuse just in case you connect too many together at once. The fuse is designed to blow so you don’t overload and damage your Christmas lights. This happens when your wattage exceeds the amp capacity of the circuit.
Why are my Christmas lights tripping the breaker?
There are three primary reasons for your breaker tripping: overloaded circuit, short in the wiring, and an old breaker. Breaker failure can happen at any time if your breaker is nearing the end of its life, but overloaded circuits and shorts in the wiring can increase during the holiday season.
How many watts is 150 mini Christmas lights?
Christmas Light Specifications
| (99) 35-lite miniature light set = 16.06 amps | [(99 x 35) x .51 watts per bulb/110] = 16.06 amps |
|---|---|
| (2) 150’/1-circuit 10mm or 13mm Plastic Neon (18 lights every 1.5′) = 14.72 amps | |
| [(2 x 1800) x .45 watts per bulb/110] = 14.72 amps |
How many amps does a Christmas light bulb use?
Our Christmas bulb electricity consumption chart shows a full list of products along with their wattage and voltage. Exchanging a C7 LED for a C7 incandescent changes the bulb’s wattage from 0.4 to 5. If we plug these numbers into the electric load calculator above, our total amps increases to 4.25.
How much energy does a string of Christmas lights use?
So, how much electricity do Christmas lights use? Your display size and choice of bulbs, whether incandescent or LED, will influence your energy bill the most. For example, a 100-count string of incandescent mini lights runs at 40 watts, while a 70 count of 5mm Wide Angle LEDs is approximately 4.8 watts total.
How many watts does an incandescent Christmas light have?
Either option would look fantastic but the LED option is 38 watts whereas the incandescent option is 1,925 watts. Both options can be easily planned for, but the incandescent option requires more understanding of what your home can handle as well as what your strings can handle.
How to calculate the power of Christmas lights?
Enter either the bulb count or the total amps. Click calculate and all empty values will be calculated. Total Amps is multiplied by 120%. Since Christmas lights draw continuous power for hours at a time, it’s important to build in additional safety measures for electricity consumption.
