The desire was to make a BIG lighted Christmas tree to celebrate the holiday season. So after Christmas last year, we went to Walmart and bought up all the lights that were on super SALE. I think that we paid about 1.99 a piece for the lights. And then they sat in the basement for about 11 and 1/2 months.....

Step 1: Some Trig

The lighted section of the lights was 23 feet. So that was the hypotenuse of the triangle. I figured the angle of the tree would be about 70 degrees, so I did some math to see what the other sides would be. With the angles, the center of the tree should be about 21 feet 7 inches. So I built the center of the tree with 6 2X4 studs 8 feet long.
I laid them out 8 8 8 and then backed them with 4 8 8 4 as you can see in the drawing. Initially I put them back to back, but they were too wobbly, so i put them together in a "T".

I added two 1x4 sections with a "U" cut out in the top to lay the lights in. See photo. This created two "valleys" for the light strings to go through.

When I had the 24 foot pole put together, i dug about a 3 foot hole, and put the pole in it.
They are not all connected together in series. &nbsp;They are only connected 4 strands (400 lights) at a time. &nbsp;(The box said don't connect more than 5 strands end to end). &nbsp;So with 32 strands, there are 8 &nbsp;sets linked together in parallel. &nbsp;They come together in 3 outdoor surge protectors and then into a heavy duty (12 guage) 100 foot extension cord (capable of up to 15 amps) and then into an outdoor plug on a 20 amp circuit.<br> <br> (32 strands * 40 watts)/120 volts = 10.6 amps<br> <br> So far so good<br> <br> I will tell you that next year it is going to be LEDs (4 watts per strand!)<br> <br> <br>
Isn't it a fire hazard to have so many strings of lights plugged in to one outlet. I have seen some lights that say don't connect more than 4 strings ?
Beautiful! I love trees like this :)
