25-Count C9 LED Christmas String Lights, 25FT Smooth Plastic Bulb String Lights on Green Wire for Indoor and Outdoor Holiday Decorating

Create a classic holiday display with this 25-count C9 LED Christmas light set. The large, smooth plastic bulbs are spaced 12 inches apart on green wire, providing approximately 25 feet of length for outlining rooflines, decorating trees, wrapping shrubs, or accenting fences and other structures.

Each energy-efficient string uses only 4.8 watts and includes end-to-end connectors, allowing up to 43 compatible sets to be connected on one plug for as much as 1,075 feet of nominal coverage. The commercial-grade, non-removable bulbs provide steady illumination, while the built-in rectifier eliminates the need for a separate adapter.

Traditional C9 Bulb Design

The large C9 profile creates a bold, nostalgic appearance suited to traditional Christmas displays. Each smooth plastic bulb measures approximately 3 inches tall by 1¼ inches wide, helping the lights remain visible from a distance.

The plastic bulb covers are less prone to shattering than traditional glass bulbs. They should still be protected from crushing, hard impacts, sharp objects, and excessive pressure during installation and storage.

The supplied information does not identify the LED color, brightness, color temperature, lumen output, beam angle, or bulb-cover color. Confirm the selected light-color variant before publishing the listing.

25 Lights Across 25 Feet

The set contains 25 C9 LEDs positioned at 12-inch intervals on green wire. This uniform spacing creates a clean, consistent appearance along straight rooflines, fences, railings, walkways, and other architectural features.

The green wire blends naturally with:

Christmas trees
Evergreen garlands
Wreaths
Shrubs and hedges
Garden foliage
Traditional green holiday décor

Measure the complete decorating route before ordering. Allow extra length for corners, roof peaks, outlet access, end connections, support cables, and gentle installation slack.

Connect Up to 43 Sets

Compatible strings can be joined end to end to create a continuous display. The supplied specifications state that up to 43 sets may be connected on one plug.

At the listed length and power consumption, 43 sets provide approximately:

1,075 C9 LED bulbs
1,075 feet of combined nominal string length
206.4 watts of combined listed power consumption

The actual illuminated coverage may differ because total set length can include lead wires, connectors, and other non-illuminated sections.

When connecting multiple strings:

Use only mutually compatible light sets.
Inspect every plug, connector, bulb, and wire before assembly.
Confirm the connection limit printed on the product label.
Join connectors fully without forcing them.
Protect outdoor connections from standing water.
Keep connectors off the ground where practical.
Calculate the complete electrical load.
Do not exceed the rating of the outlet, extension cord, timer, or power strip.
Never exceed the stated maximum of 43 connected sets.

The maximum connection quantity should always be verified against the instructions and electrical label supplied with the actual product.

Energy-Efficient LED Lighting

Each 25-light set consumes approximately 4.8 watts. This low power requirement makes the string suitable for larger holiday displays while using less electricity than traditional incandescent C9 lighting of a comparable count.

Actual energy consumption depends on:

Number of connected sets
Daily operating time
Length of the decorating season
Local electricity rates
Timers or control equipment
Electrical supply conditions

At the stated 4.8-watt rating, connecting the maximum 43 sets would produce a combined nominal load of approximately 206.4 watts.

Built-In Rectifier

The string includes a built-in rectifier and does not require a separate external adapter for normal operation. Follow the voltage and connection instructions printed on the product label before plugging the lights into an outlet.

A rectifier does not by itself confirm that the lights are flicker-free. Although the description states that the set provides a steady and consistent light source, visible flicker can depend on the electrical design, supply conditions, and viewing or camera environment.

The input voltage, frequency, plug configuration, fuse rating, and rectifier specifications are not provided and should be confirmed before publication.

Non-Removable Bulbs

The LEDs are described as permanently attached to the string. They are not designed to be unscrewed, removed, or replaced individually.

This ready-to-use construction offers several practical benefits:

No separate bulbs need to be installed.
Bulbs cannot loosen through ordinary handling.
Electrical contacts are less exposed than those of removable-bulb strings.
The string can be installed directly after inspection and testing.

Do not twist, pull, puncture, or attempt to remove a bulb. If a bulb or its base is damaged, discontinue use according to the manufacturer’s instructions.

The supplied information does not state whether the rest of the string remains illuminated if one LED fails.

Steady Holiday Illumination

The set is described as providing steady light without an automatic flashing or twinkling effect. No lighting modes, controller, remote control, timer, or adjustable animation effects are identified.

Dimming compatibility is also not specified. Do not connect the lights to a dimmer, flashing controller, or electronic effects device unless the manufacturer confirms that the equipment is compatible.

Indoor and Outdoor Decorating

The lights are described as UL Listed for indoor and outdoor use. Their large C9 bulbs and 12-inch spacing make them suitable for decorating:

Rooflines
Eaves
Gutters
Large Christmas trees
Outdoor trees
Shrubs and hedges
Fences
Railings
Porches
Patios
Pergolas
Garlands
Wreaths
Windows
Entryways
Storefronts
Restaurants
Hotels
Event venues
Commercial holiday displays

Outdoor suitability does not mean the lights or their connectors can be submerged. Keep plugs and electrical connections away from standing water, roof runoff, drainage areas, irrigation equipment, and locations where snow or ice may collect.

Roofline Installation

The 12-inch bulb spacing can produce an evenly arranged display along roof edges and gutters. Use mounting clips designed for C9 bulbs and the applicable roof surface.

General roofline setup:

Measure the roofline and plan the outlet location.
Inspect and test every light set at ground level.
Disconnect the lights before installation.
Install suitable clips at consistent intervals.
Position one bulb in each clip.
Leave gentle slack at corners and connection points.
Keep the wire away from sharp flashing and rough edges.
Protect plugs and end connections from collected water.
Reconnect power only after the complete installation has been inspected.

The reference to “all in all clips” appears to mean all-in-one holiday-light clips, but no specific clip type or brand is identified. Confirm compatibility with the C9 bulb dimensions, wire, gutters, shingles, and other mounting surfaces.

Do not use nails, screws, staples, or tacks through the electrical wire.

Patio and Suspended Installation

For patio displays or other suspended installations, a properly rated support cable may help maintain a straight, professional-looking line. Aircraft cable or another weather-resistant support wire must be selected according to the span, load, mounting points, and local installation requirements.

The light string should not be used as its own structural support across a long open span.

When suspending the lights:

Attach the support cable to suitable structural anchor points.
Keep tension on the support cable rather than the electrical wire.
Fasten the light string with compatible clips or loose ties.
Avoid overtightening ties around the insulation.
Allow for wind movement and temperature changes.
Keep the bulbs away from doors, fans, heaters, and moving objects.
Do not install the lights beneath unsupported or deteriorated structures.
Follow applicable building and electrical requirements.

Mounting cable, anchors, clips, ties, and installation tools are not identified as included.

Tree and Shrub Installation

When placing the lights on trees or shrubs:

Test the string before installation.
Avoid branches with sharp or broken edges.
Do not pull the wire tightly around trunks or growing limbs.
Use suitable clips or loose ties where additional support is required.
Keep plugs and connectors above wet soil.
Route extension cords away from walkways and landscaping equipment.
Remove the lights before pruning or trimming the plant.
Do not use the electrical string to support ornaments or other decorations.

For large trees, calculate the required length before climbing or using installation equipment. Follow safe ladder practices and keep all lights away from overhead utility lines.

Electrical and Installation Safety

Read and retain all instructions supplied with the product.
Confirm that the outlet voltage matches the light set’s rating.
Inspect the complete string before every installation.
Do not use the set if a plug, connector, wire, bulb, socket, or rectifier is damaged.
Use a properly protected outdoor-rated outlet for exterior displays.
Use only outdoor-rated extension equipment outdoors.
Keep plugs and connections elevated and protected from water.
Do not handle plugs or connectors with wet hands.
Disconnect the lights before installing, repositioning, or cleaning them.
Do not cut, splice, shorten, extend, or modify the string.
Do not remove or bypass any plug fuse or protective component.
Do not connect more than 43 compatible sets.
Do not energize the string while it is tightly coiled or inside its packaging.
Keep the lights away from open flames, heaters, fireplaces, grills, and hot surfaces.
Keep the wire away from doors, windows, or furniture that could pinch it.
Keep the product away from children or pets that may pull, chew, or become entangled in the wire.
Do not overload outlets, timers, extension cords, or power strips.
Follow all warnings printed on the product label and packaging.
