LED net lights draped over a hedge

Copper wire net & firefly bunch lights — geometry, not bulb count, decides whether the hedge reads bright from the front.

You draped the net over the hedge. Walked around to the front. Dark. The lights are all on the far side, glowing at the trees you don't see.

That is the failure that kills 80% of net light jobs, and it has nothing to do with the lights. It's geometry. Net lights are a two-dimensional grid slapped onto a three-dimensional bush, and the grid only covers the two faces it physically touches. If you throw it over the top, the front face — the face your street sees — is left to luck.

The Real Problem: You're Lighting the Wrong Face

A 4'x6' net is the standard size, and it will cover a normal box-hedge in under a minute. But "covers" means it contacts the surface. A hedge viewed from the street is really three surfaces: front, top, and one visible side. A single net draped over the top hits the top and sags down one side. The front stays dark unless you push the bottom edge into the planting bed and stake it there.

Here is the fix that actually works:

  1. Trim first, measure second. Clear dead branches and debris. A net over ragged growth tangles and sheds light. Then measure the height, width and depth of the shrub — not just the width. Nets come in rectangular, square and cone/cylindrical shapes. A cone-shaped boxwood wants a cone net; draping a flat square net over a cone leaves the tip dark and the base strangled.
  2. Bottom edge goes into the soil. This is the step everyone skips. Push the bottom rail into the ground with stakes so the whole grid pulls taut against the front face. A loose bottom edge is why the light sags to the back. Taut grid = even front illumination.
  3. Test before you hang. Plug the net in on the ground, look for dead bulbs and frayed leads, then hang. Finding a dead bulb after the net is staked on a cone hedge is miserable.

Chain Limits: Where the String Actually Dies

People blow their net string by chaining too many sets. On one outlet you can typically link 14 to 21 LED net sets end-to-end. Incandescent nets: max 3. Beyond that the wire runs hot, the transformers sag, and the first winter frost finds your one thin solder joint.

The other silent killer: outdoor connections. Any splice or extension cord joint that sits exposed needs a proper waterproof connector, not electrical tape. Tape fails in the first rain. That is the same failure mode we see in outdoor light strings generally — the light survives the winter, the connection doesn't.

Cone vs Box: Match the Net to the Plant

  • Box / square hedges — rectangular net, stake the bottom, and if the hedge is visible from two sides, run a second net on the opposite face. A single net on a walkway hedge looks great from one angle and invisible from the other.
  • Cone-shaped trees (yew, boxwood, small evergreens) — cone net or wrap. Flat nets over cones strangle the base and starve the tip.
  • Round ball shrubs (hydrangea, lavendar balls) — wrap the net around the circumference and stake the seam at the back, not the front. Front seam = visible wire line in the light.

The One-Number Rule

Coverage density matters more than bulb count. A "40-bulb" net over a 4'x6' grid is roughly one bulb per 25 square inches. That is the sweet spot. Go denser and you waste money on bulbs you can't see behind the leaves. Go sparser and you get the "pinprick" look — lots of dots, no glow. For a hedge, aim for the 1 bulb / 20-30 sq in range and let the leaves scatter the light.

What We See Fail Every Season

Three patterns, all fixable:

  1. Bottom edge loose — light sags to the back, front looks dark. Stake it.
  2. Over-chained sets — past 21 LED or 3 incandescent on one outlet. The wire runs hot, the joint dies in month six. Split the string.
  3. Unprotected splices — taped extension cords in the rain. Swap to waterproof connectors.

If you are building a wider install — a hedge row, a column line, or a hedge plus tree combo — the same principles apply. For the light itself, our net light line is built for outdoor exposure and pairs with the same chain-limit math above. If you're also doing a candle table or porch accent in the same install, the LED candle line runs off the same outlet budget and doesn't trip the incandescent chain limit.

FAQ

How many net lights can I chain on one outlet?
LED: 14-21 sets. Incandescent: 3 sets. Check the set's wattage rating — the limit is total draw, not set count.

Why is my hedge dark from the street but lit from the back?
The bottom edge isn't staked. The net sags to the far side. Push the bottom rail into the ground and pull the grid taut against the front face.

Can I use net lights on a cone-shaped tree?
Yes, but use a cone or cylindrical net. A flat square net over a cone strangles the base and leaves the tip dark.

Do I need outdoor-rated connectors?
Any splice or extension joint in the rain needs a waterproof connector, not tape. Tape fails in the first storm.
