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).
How many watts do LED string lights use?
Today, most of the new lamps are based on LEDs. The difference is huge – a string of 100 lights consumes about
8 watts

2,100 watts
to power.
How many amps does a string of LED Christmas lights use?
Since each string is 40.8 watts, we know that each string needs
0.34 amps
(40.8÷120).
How many watts do Christmas lights use per hour?
These lights draw
130 Watts
constantly. This translates to 0.13 kWh per hour, or 3.16 kWh per day and 97.96 kWh per month, with an additional electrical cost of $12.73. But when using the four strings of lights needed to cover a 7ft tree, it goes up.
Does LED lights increase electric bill?
LED strip lights
do not cost a lot of electricity
compared to traditional incandescent lights. Consumption is directly determined by the length of the strip light and its light density. A standard 5-meter strip will cost less than $3 a year to run, on average.
How do I know the wattage of my Christmas lights?
This happens when your wattage exceeds the amp capacity of the circuit. How Many Watts Do My Christmas Lights Use? Watts is a
measurement of the amount of
energy used. Wattage is typically provided per bulb or string and is listed on the bulb or near the UL tags on a string.
How many LED lights can you put on one circuit?
