How much electricity is used by a string of 100 mini christmas lights? (in watts)?

Posted by Jade Martins on Dec-16-2009

Just regular christmas lights, not leds or anything fancy.

Many of the modern mini-lights are close to 0.45 watts each. One hundred of these should take 45 W. These are the ones that fit in a tiny plastic socket that is pushed in, not screwed in.

C-7 lights (they look like miniature light bulbs, with a small socket; they screw in) are between 3 and 7 W each, depending on the model and make. One hundred could eat up to 700 W (However, they rarely come in sets of that many lights).

    I looked on the boxes of my set of mini-lights and C-7 lights.

    for this question look at the book and use this conversions
    1 watts = 1 joules/sec
    1 horsepower = 746 watts
    1 kilowatt/hour =1000 watts/hour

  5. farmer Said,

    Well, how many of such strings can you gang on a single outlet without blowing the breaker? I’d guess maybe 4.
    So how much

    current soe each strand draw?

    P = IV (rms) ?

    V = 120 Volts

    V(rms) maybe 80 Volts or so

    So I’d guess about 250 Watts.

    How many 60 watt bulbs can you have on the same
    circuit in a house?
