# How many lights for these trees?

I am working up a price for 30', 20', and 15' trees. The customer wants the trees lighted well but not with the tight wrap every branch approach.

He wants the 30' done with c7s and the 20 and 15 with minis how could I calculate how much I need?

Any info would be great

Well, you do some geometry. You need to figure out the diameter of the tree at its widest point, then you need to figure out your spacing and how many times you;ll need to go around the tree to cover it in lights. So if your tree has a 30 ft diamter, and you need to go around about 10 times to make it look nice, you'll need 300 feet of lights. Then add in the trunk if you are wrapping that as well.

with minis-- height x width divided by .25 gets you pretty darn close.
thats for 50 light strands.

So do you do the diameter because it gets smaller as you go? 60' of your lights are gone with the first round
