The best outdoor Christmas lights for trees

The commercial 5 mm wide-angle string is the format built for tree wrapping: a small concave lens that throws light sideways, on a green wire that disappears into bark and foliage in daylight.

Wrapping a tree is a different lighting problem from outlining a roof, and the bulb that solves it is different too. A roofline wants a big bulb that reads as a distinct point from the street. A trunk wants a small bulb, close together, that turns the bark into a glowing column — and that is what the 5 mm wide-angle format is for. Christmas Lights, Etc identifies 5 mm LED wide-angle lights as the type most commonly used on outdoor trees, and the reason is the lens: it is concave, so it spreads light sideways around the curve of the trunk instead of firing it into the street.

Wintergreen's 70-count set runs 24 feet on green wire. Green matters more than people expect. Lights are lit for roughly eight hours a night and the wire is visible for the other sixteen, and white wire spiraled up a dark trunk is a barber pole in daylight. Green disappears against bark and evergreen foliage; brown wire, sold in the same format, disappears against deciduous trunks.

The practical limit is length. Twenty-four feet sounds like a lot until you wrap it: at the 6-inch spiral spacing Christmas Lights, Etc recommends for the best look, a single set covers a surprisingly short stretch of a mature trunk. Buy by measured length rather than by set count, and buy connectable so the whole trunk runs off one feed.

What you give up against a socketed C9 is repairability — these are prelamped, so a failed section is a failed set. For a trunk wrap that is an acceptable trade, because the wire is doing structural work around a rough surface and the failure mode is usually abrasion rather than a dead bulb.

A stretchable net sized for a trunk rather than a string you spiral by hand. You wrap once, the elastic takes up the slack, and the spacing comes out even without you measuring it.

The slow part of lighting a tree is not the ladder. It is spiraling a string up a trunk by hand and discovering at the top that the spacing drifted, so the bottom four feet are dense and the top four are sparse. Tree wrap net solves that mechanically: the lights are held in a net with a stretchable cord woven through it, so you hold one edge against the trunk, wrap once, and the elastic pulls the spacing even.

Christmas Lights, Etc describes the StretchNet Pro as expandable to fit a variety of trunk diameters, which is the whole point — a trunk tapers, and a fixed net would be tight at the bottom and loose at the top. The brown wire version is the one to buy for a deciduous trunk; green is right if you are wrapping an evergreen or a column against foliage.

The honest limitation is that this is a trunk product and nothing else. It does not go up into branches, it does not follow a fork, and on a multi-stem or heavily gnarled tree it will not sit flat. For those, hand-spiraled 5 mm string is still the answer, and Christmas Lights, Etc's own guidance is to carry the wrap up the trunk and roughly three to four feet into the extending branches, choosing branches rather than trying to do all of them.

Price per lit foot is higher than plain string. What you buy is time, and a finish that looks deliberate rather than improvised — which matters most on the one specimen tree at the front of the house that everybody actually looks at.

A mesh of LEDs you throw over a shrub. It is the highest ratio of visible result to time spent of anything on this site, and it is why net lights belong in most first displays.

Net lights solve one problem completely: covering a bush. Wrapping a shrub by hand takes twenty minutes and looks hand-wrapped. A net takes about ninety seconds and looks even, because it is a grid.

Dazzle Bright's sets run 360 LEDs in a mesh with eight modes. The mode controller is more useful than it sounds — on a bush the steady setting is almost always right, but the slow-fade setting reads well on a hedge line where a steady wall of light looks flat.

Where nets fail is geometry. They want a roughly rectangular volume. A tall juniper, an irregular ornamental grass, or a sparse young shrub will let the net sag into it and you get a lumpy result that reads as cheap. Measure the bush: if it is meaningfully taller than the net is wide, buy string and wrap it.

Takedown is the quiet advantage. A net comes off in one motion and folds. A wrapped shrub has to be unwrapped, in the cold, in January, and that is the job everyone underestimates.

The commercial-grade C9 most professional installers use, sold in retail quantities. Thick polycarbonate lenses and a green commercial-gauge wire that survives being handled every year.

C9 is the big, faceted, traditional-looking bulb — the one that reads as Christmas lights from the street rather than as a glow. Wintergreen's OptiCore line is the version professional installers buy, and the reason is not brightness. It is that the lens is polycarbonate rather than glass, and the manufacturer rates the bulbs at 60,000 hours. A season is roughly 45 days at eight hours, so about 360 hours. The arithmetic on that rating is generous enough that bulb failure stops being the thing that ends a strand's life; handling damage is.

The practical case for buying commercial-grade C9 is replaceability. Each bulb screws into an E17 socket. When one dies, you replace one bulb for a couple of dollars instead of pulling a 100-light strand off the roof. Over five seasons that is the whole argument, and it is why the same boxes keep appearing on the same houses.

The honest counterpoint: this is expensive per foot, and it is sold in 25 ft sets. A 180 ft roofline is eight boxes plus spare bulbs, which is a real number. If you are lighting one gable over the front door and you are not sure you will do it again next year, a cheaper set is the right call and we would not argue.

One buying note that trips people up — C9 sets and C9 bulbs are sold separately as often as together. Check whether the listing you are on is a complete lit set or a box of replacement bulbs, because the photos look nearly identical.

Solar solves exactly one problem — the far corner of the yard with no power — and it is genuinely good at that. It is a poor substitute for a wired run anywhere an outlet exists.

Solar Christmas lights have a reputation problem, and most of it is deserved for the wrong reason. They are not bad products. They are products bought for the wrong job.

The right job is the tree at the end of the driveway, the mailbox, the fence line fifty feet from the house — anywhere running a cord means either a trip hazard or a trench. For that, solar is the only reasonable answer and it works.

The wrong job is the front of the house, where an outlet exists. December has the shortest days of the year and the lowest sun angle, which is precisely when a solar panel charges worst and you want the lights on longest. Brightown states 8-10 hours on a full charge; in late December, in the northern half of the country, after a cloudy day, expect meaningfully less. That is physics, not a product defect.

Practical placement note: the panel needs actual sky, not shaded sky, and it needs brushing clear after snow. A panel under two inches of snow is an off switch.
