Red Christmas Lights: How To Choose Red C9 Bulbs, Mini Light Strings, And Net Lights
Red is the one Christmas color that can carry an entire house by itself. A roofline of red C9s reads as a deliberate choice from the street, and red pairs cleanly with white for a candy-cane look or with green for the traditional one. The harder part is choosing the right red product for each part of the display, because "red Christmas lights" covers retrofit bulbs, mini light strings, net lights, and several lighting effects that behave very differently once they are up.
This guide walks through each lens style, the specs that matter, how to mix red with other colors, and how to work out quantities before you order. If you are looking for layout inspiration first, start with 10 ways to decorate with red Christmas lights, then come back here to choose the products.
Start With The Job, Then Pick The Lens Style
Every red light we carry falls into one of three families, and each one has a job it does best:
- C9 and C7 retrofit bulbs screw into a socket stringer. They are the right choice for rooflines, gutters, ridgelines, walkways, and anywhere you want bold, evenly spaced points of light that read from the street.
- Mini light strings (5mm, M5, C6, and G12 lens styles) have the bulbs sealed onto the wire. They are the right choice for wrapping tree trunks and branches, railings, wreaths, garland, and shrubs.
- Net lights are a grid of 5mm lights that drape over hedges and bushes in one move.
A useful rule: bulbs outline the architecture, strings and nets fill the landscape. Mini light strings are not a roofline product, so plan C9s or C7s for the house and use strings everywhere else.
Red C9 And C7 Bulbs For Rooflines And Walkways
Our red retrofit bulbs are ProCore® LED bulbs with a polycarbonate lens and a corrosion-resistant nickel base. The C9 Red Faceted ProCore® LED bulbs use an E17 base and draw 0.84 watts per bulb; the C7 Red Faceted ProCore® bulbs use the smaller E12 base and draw 0.8 watts. Both come in packs of 25, are dimmable, carry an IP67 rating, and are backed by a 3-Season Reindeer Proof™ Warranty.
C9 Or C7?
C9 is the larger bulb and the standard for rooflines, especially on two-story homes or houses set back from the street. C7 is the smaller bulb and suits single-story eaves, windows, door frames, fences, and walkways where you are viewing the lights from closer up. The base sizes are different, so match the bulb to the stringer: C9 bulbs need a C9 (E17) stringer and C7 bulbs need a C7 (E12) stringer.
Faceted Or Smooth?
Faceted lenses break the light into sharp, sparkling points and are the classic Christmas look. Smooth lenses give a softer, more uniform glow that some decorators prefer for modern architecture. Red is available both ways: the C9 Red Smooth ProCore® bulbs and the C7 Red Smooth ProCore® bulbs use the same bases and wattage as their faceted versions.
Bulb Packs Or A Complete Set?
Bulb packs do not include a stringer. For custom lengths, pair them with a stringer from our C9 stringer collection, such as the 100' C9 stringer with 100 sockets at 12" spacing. If a 25-foot section is all you need, the C9 Red Faceted ProCore® String Light Set is a complete 25' set that includes 25 bulbs and a 25-socket stringer at 12" spacing, and up to 40 sets connect end to end.
Red Mini Light Strings For Trees, Railings, And Wreaths
All of our red mini light strings share the same core construction: bulbs fused to the sockets in single-molded, sealed sockets, 4" bulb spacing, green wire, male and female stackable plugs, an IP44 rating, and a 3-Season warranty. If one light goes out, the rest stay lit. The difference is the lens shape, which changes how the light looks from a distance.
| String | Lens Look | Lit Length | Max End To End |
|---|---|---|---|
| 100 5mm Red | Wide-angle 5mm, bright and even | 33 ft | 27 strings |
| 50 5mm Red | Wide-angle 5mm, bright and even | 16.33 ft | 90 strings |
| 100 M5 Red | Elongated faceted lens, fuller glow | 33 ft | 27 strings |
| 70 C6 Red | Strawberry-shaped faceted lens | 23 ft | 45 strings |
| 70 G12 Red | 12mm round faceted globe | 23 ft | 45 strings |
For wrapping tree trunks and branches, the 5mm strings are the workhorse. The 100-light version covers more trunk per plug, and the 50-light version is handy for small trees, porch posts, and wreaths where a long string would leave excess wire. The C6 and G12 strings are the choice when you want each bulb to read as a small jewel rather than a point of light; they catch and scatter light in several directions, which looks especially rich in red.

Red Net Lights For Hedges And Shrubs
Wrapping a boxwood with strings is slow work. The 5mm 4' x 6' Red LED Net Lights put 100 5mm LEDs on a 6" x 4" grid that drapes over a shrub in a minute, and up to 18 nets connect end to end. For a traditional two-color hedge, the Red, Green net lights alternate both colors across the same grid. Our net lights buying guide covers how to size nets to a hedge.
Steady, Slow Fade, Or Strobe
Most red displays are steady, and steady is the right default for rooflines and trunk wraps. Two effects are worth knowing about if you want one element of the display to move.
DreamSpark® Slow Fade
DreamSpark® bulbs fade on and off slowly, each on its own rhythm, so the string shimmers without flashing. The 70 5mm Red DreamSpark® string is all red; the 70 5mm Red, Green, and Cool White DreamSpark® string gives the traditional Christmas palette the same gentle motion. For shrubs, the Red, Green DreamSpark® Smooth Fade net lights do the same thing in net form. DreamSpark® products are technically dimmable, but dimming can produce undesirable visual effects, so run them at full power.
SuperSpark® Strobe
Strobes are a very different effect: sharp, bright flashes that are meant to be noticed. The C9 Red SuperSpark® LED Strobe Bulb is sold individually and fits any C9 socket, flashing at random between 40 and 180 times per minute from 8 SMD LED chips. Mixing a strobe into a run of steady red C9s, every fifth or tenth socket for example, adds sparkle to a roofline or large tree without rewiring anything. Strobe bulbs are not dimmable, so leave them off any dimmed circuit. For more on strobe effects, see our Christmas strobe lights guide.
How To Combine Red With Other Colors
Red And White For A Candy-Cane Look
On a roofline, alternate red faceted C9s with cool white faceted C9s in the same stringer. A one-to-one pattern gives the crispest candy-cane stripe; two red to one white keeps red dominant. Cool white (6400K) gives the sharpest contrast against red, while warm white (3000K) softens the pairing. For trees and railings, the 70 5mm Red and Cool White string puts both colors on one string. If you want sparkle in the white, the 50 5mm Red and Cool White Dazzle string runs three steady red bulbs followed by one rapid cool white strobe, repeating down the string.
Red And Green For A Traditional Display
The 70 5mm Red and Green string is the simplest way to get the classic pairing on trees and garland. The 50 5mm ColorCraft® Christmas string adds cool white to red and green, a color palette available only at The Christmas Light Emporium.
Where Red Works Best On Its Own
All-red works best when it is concentrated: a full roofline, a row of wrapped trunks, or a mega tree. Mixing red into a multicolor display is fine, but a single-color red element gives the eye a clear anchor.
How Many Red Lights To Order
- Rooflines: measure every run in feet. At 12" spacing you need one C9 or C7 bulb per foot, plus a few spares. A 100-foot roofline takes four packs of 25 bulbs and 100 feet of stringer.
- Tree trunks: multiply the number of wraps by the trunk circumference, then divide by the lit length of your string. Our tree wrapping guide walks through the spacing math.
- Shrubs: one 4' x 6' net covers roughly a 4' x 6' face; larger hedges take nets side by side, connected end to end.
Because LEDs draw so little power, the practical limit on a run is usually the maximum end-to-end number listed on each product, not the outlet. Stay under that number, start each run from a GFCI outlet, and put the whole display on an outdoor photocell timer so it turns on at dusk every night.
Our Short List
- Red roofline: C9 Red Faceted ProCore® bulbs on a C9 stringer.
- Red tree wraps: 100 5mm Red strings.
- Red shrubs: 4' x 6' Red net lights.
- Candy-cane roofline: red and cool white faceted C9s alternated in one stringer.
- One element with motion: a few C9 Red SuperSpark® strobes or a DreamSpark® string.
