A rule of thumb, how to wrap a tree so the lights reach the middle, and which strands are worth the extra money.
Most decorators work with about 100 mini lights for every foot of tree height. A six-foot tree takes around 600, a seven-and-a-half-foot tree around 750. If you like a softer tree, stop at two thirds of that. If you want the tree to glow from across the street through the window, go up by half.
Count by lights, not strands. A 100-count strand and a 200-count strand look very different on the same branch, and the box always tells you the count.

A tree lit only on the outside looks flat, like a cone with a light shell. Start at the trunk at the bottom, run the strand out along a branch and back in, then move to the next branch. It takes longer, and the tree gains depth you can see from the couch.
Work from the bottom up with the plug end at the base, so the next strand joins where the last one stopped.

Connectable strands plug into each other, but not without limit. Each strand's own instructions give the maximum. The federal product safety agency puts a number on the old kind of bulb:
Never string together more than three sets of incandescent lights and never overload electrical outlets.
U.S. Consumer Product Safety Commission, Holiday Safety. Read 29 September 2026.
LED strands draw much less power, so their limit is higher, often several times higher. The number is still printed in the instructions for each model, and it is the one to follow. On our product pages we list it wherever the maker gives it.
Before a single strand goes on the tree, plug it in on the floor. It is far easier to find a dead section there than halfway up a branch. The U.S. Fire Administration puts it plainly:
Inspect holiday lights each year before you put them up. Throw away light strands with frayed or pinched wires.
U.S. Fire Administration, Holiday Fire Safety. Read 29 September 2026.
The same page carries a figure worth remembering when you are tempted to keep a strand with a pinched wire for one more year:
Almost one-third of home Christmas tree fires are caused by electrical problems.
