Almost every question about how a display will look comes down to three choices: which bulb, which color, and how far apart. Get those right and a modest budget looks expensive. Get them wrong and a large budget looks cluttered.
The bulb shapes
- C9 — the classic. The big strawberry-shaped bulb, about 2½ inches tall. This is the traditional American roofline look and what we use as standard. Individually visible from the street, warm, and unmistakably deliberate. Best on longer rooflines and larger homes.
- C7 — the smaller sibling. Roughly two-thirds the size. Reads more delicate, suits cottages, smaller village homes and detail runs around porches and dormers. Slightly closer spacing to keep the line continuous.
- Mini lights. Small and dense, best for wrapping — trunks, columns, railings, garland and hedges. Wrong for a roofline, where they read as a fuzzy glow instead of a line, but the right answer for almost everything vertical.
- Bistro and catenary. Larger spaced bulbs on heavier cable strung overhead across a courtyard or terrace. Hospitality lighting, not roofline lighting.
Color temperature — the choice people underestimate
This matters more than bulb shape, and it is where most DIY displays go wrong.
- Warm white (about 2400–2700K). Soft, slightly amber, closest to the old incandescent look. This is the default we recommend for wine country because it flatters stucco, stone and timber and photographs beautifully at dusk. It is also what reads as expensive rather than festive.
- Pure or cool white (3500K and up). Crisper and more contemporary, and it can look striking on modern architecture. On warm-toned stucco it can go slightly blue and clinical.
- Color. Traditional multicolor, or single-color schemes. Genuinely fun, and right for some houses and most families with young children. Just commit — half multicolor and half warm white is the one combination that never works.
- The mixing rule. Never mix color temperatures on a single elevation. Two batches of “warm white” from different manufacturers will not match, and the eye catches it instantly from the street.
Spacing
C9 bulbs are typically set at 12-inch spacing, which is the standard for a reason: it reads as a continuous line of distinct points from the street. Tighter spacing at 8 inches gives a denser, more luxurious line and costs proportionally more. Wider spacing at 15 inches saves money and starts to look sparse on a long run.
C7 usually goes at 8 to 12 inches, because the smaller bulb needs to be closer to hold the line.
The practical takeaway: if a quote seems low for your linear footage, ask what spacing it assumes.
Why LED, not incandescent
- Power. C9 LED draws about one watt per bulb; incandescent C9 draws seven to ten. A 200-bulb roofline is 200 watts against roughly 1,600 — the difference between running a couple of light bulbs and running a space heater.
- Heat. LEDs run cool. Incandescent bulbs get genuinely hot, which matters when they sit against dry landscaping in a region that thinks hard about fire.
- Circuit capacity. With LED you can run a whole house on a single exterior circuit. With incandescent you are splitting circuits and often finding you need more power than the house has.
- Lifespan. LEDs last many seasons. Incandescent filaments fail constantly, and on a series run one failure takes a whole leg dark.
A simple way to choose
- Traditional home, longer roofline, want it to look established: C9, warm white, 12-inch spacing.
- Cottage, village home or lots of fine trim: C7, warm white, 8 to 12-inch spacing, with mini lights on porch posts.
- Modern architecture, clean lines: C9 in pure white, or permanent track lighting, which suits contemporary rooflines better than anything seasonal.
- Family house, kids, want it fun: multicolor C9 on the roofline, warm white minis in the trees so it still reads as designed.
- Winery or hospitality: warm white throughout, C9 on buildings, minis on trunks, bistro over terraces.

Common questions
What is the difference between C9 and C7?
Size. C9 is about 2½ inches tall, C7 about two-thirds of that. C9 is the classic American roofline bulb and suits larger homes and longer runs; C7 is more delicate and suits cottages and detail work.
Which color temperature should I choose?
Warm white, around 2400 to 2700K, for most wine-country homes. It flatters stucco and stone, photographs well at dusk, and reads as expensive rather than loud. Cool white suits modern architecture; color suits families who want fun.
Can I mix warm white and color?
On a single elevation, no — it looks like a mistake. Across a property, yes, if it is deliberate: warm white on the building and color in a specific feature tree, for example.
Why does my neighbor’s white look different from mine?
Different color temperature, or two batches from different manufacturers. It is the most common visible flaw in a DIY display and the reason we source bulbs from a single lot.
Is tighter spacing worth the extra cost?
On a prominent front elevation, often yes — 8-inch spacing looks noticeably richer. On long side runs that nobody looks at closely, 12-inch is fine and the money is better spent elsewhere.
Do LEDs look artificial compared to old incandescent lights?
Good warm-white LEDs at 2400 to 2700K are very close to the old incandescent look. Cheap LEDs at higher temperatures are what people are remembering when they say that.
Can I use mini lights on a roofline?
You can, but it reads as a fuzzy glow rather than a defined line. Minis belong on trunks, columns, railings and garland, where the wrapping is the point.
What about permanent track lighting instead?
Different look — a cleaner, more modern line rather than distinct bulbs — and it works year-round. Worth considering if you have booked seasonal installs three or more years running. See our permanent lighting page for an honest comparison.
