A local park is advertising they are running just over one million
lights in their display. Most are the miniature type, but there are
some of the outdoor C9 bulbs (probably 3000 of them), and about 20
flood bulbs. (100 watt) Plus some animation motors. I'm
mathematically challenged.... Can anyone come up with some sort of
amperage to run all of this. I'm just trying to figure out what it
takes to run this display that covers about 5 acres. (for the heck of
Very nice display !
I agree this is sort of a guess because the strings are probably
different lengths and all, but yes, they are the average mini lights
except for those C9s and floods and a few other things. I was mainly
asking about the mini lights. The rest is pretty easy to figure.
That's a lot of watts !!! I'd hate to pay their elec bill.

The miniature lights are usually in series on 50 bulbs. A series takes
about 200mA. That would mean 250 lights per amp, so 1 million
miniature lights would use 4KA (4,000A) or 480KW (480,000W).
Or course it would be more with C9 or other lights too.
According to my measurements (I don't have nearly that many lights,
but do have enough to need to consider electrical load) a string (25)
of C9 lights uses about 1.5A (180W). The lighted animated (head moves
up & down) deer I have (40-inch doe, 48-inch buck) use around .6A
Incandescent lights use somewhat more current when starting.
Extension cords claim 13A, but can overheat if current exceeds 10 or
BTW, I have pictures of my lights at
http://notstupid.laughingsquid.com/winter.html . I don't have this
year's pictures yet (but expect to have them soon). This year, they
will look similar to last year's, but with a few more.
