How to choose the right outdoor string light
Updated June 2026Independently researchedNo paid placement.
The best outdoor string light for you balances bulb type, length, power source, and weather resistance based on where and how you plan to use them. LED bulbs offer the longest life and lowest energy cost, while incandescent gives a classic warm glow. Look for weather-resistant construction with an IP rating of at least IP44 and consider plug-in for reliability or solar for easy placement.
What type of bulb should I look for in outdoor string lights?
The two main choices are incandescent and LED. Incandescent bulbs produce that familiar warm, amber glow many people love for patios and gardens. They’re inexpensive to buy but use a lot more electricity and typically last only a few thousand hours. They also get hot, which can be a concern near dried leaves or fabrics. LED bulbs have come a long way. Many now offer a warm color temperature (around 2700 K) that rivals incandescent. They use up to 90% less energy, last tens of thousands of hours, and stay cool to the touch. The trade-off is a higher upfront cost, but the savings add up quickly if you leave lights on often. Some LEDs are dimmable, though you’ll need a compatible dimmer switch or a set that includes it. A growing number of string lights now also offer color-changing LEDs with a remote or app control, which can be fun for parties.
How long and how bright do my string lights need to be?
Length and brightness depend on your space. For a standard 10-foot by 12-foot patio, a 30- to 50-foot string is usually enough to drape around the perimeter or hang across the middle. If you want to cover a larger yard or string lights over a dining table, you may need two or three sets totaling 75 to 100 feet. Most string lights let you connect multiple strands end-to-end, but check the maximum wattage, many LED sets allow up to 10 or 15 linked strands. Brightness is measured in lumens. A typical patio light with 10 to 15 warm‑white LED bulbs each puts out about 50 to 80 lumens, which creates a soft ambient glow. If you want brighter illumination for reading or cooking, look for sets that use larger bulb styles (like G40 or T20) or ones with higher total lumen output. Some also come with a dimming function so you can adjust the mood.
Should I get plug-in, solar, or battery-powered string lights?
Plug-in string lights are the most reliable. They provide consistent brightness and can run for hours without fading. You just need an outdoor-rated extension cord and a nearby GFCI outlet. They’re the best choice if you have easy access to electricity and don’t mind managing a cord. Solar-powered lights are great for spots far from an outlet, like a pergola or a fence line. They charge during the day and turn on automatically at dusk. The catch is that brightness depends on the solar panel’s exposure and battery capacity. On cloudy days or in shaded areas, they may be dimmer and shut off earlier than you’d like. Battery-powered lights (usually with AA or rechargeable packs) are another no-outlet option, but you’ll need to change or recharge batteries regularly, which can get tiresome.
What about weather resistance and durability?
Outdoor string lights need to withstand rain, snow, UV rays, and temperature swings. Look for an IP (Ingress Protection) rating of at least IP44, which means the lights are protected from splashing water and small particles. Many quality sets are rated IP65, meaning they’re also dust-tight and can handle low-pressure water jets, fine for heavy rain or even a garden hose. The bulb material matters too. Plastic (polycarbonate) bulbs are shatter-resistant and safer near play areas, but they can become brittle after a few seasons in direct sun. Glass bulbs feel more premium and transmit light better, but they break easily if knocked. Some sets use a flexible silicone or rubberized bulb that combines durability with a soft look. Also check the wire: a rubber or PVC jacket resists cracking better than thin vinyl, especially in cold climates.
How do I hang and install outdoor string lights safely?
For a clean, secure installation, start by planning your layout. Use hooks or screw‑eyes rated for outdoor use, placed every few feet along the path. If you’re hanging lights between two points (like a house and a tree), consider a cable or pole kit that includes a stainless‑steel wire to support the string. This takes the tension off the light wire and keeps the line straight. Always use an outdoor‑rated extension cord and plug into a GFCI‑protected outlet. If your lights are long or you’re connecting multiple strands, don’t exceed the maximum wattage, it’s printed on the string’s tag. For a temporary setup, adhesive hooks and zip ties work, but they may fail in strong wind. For permanent installations, screw‑in or masonry anchors are best.
Are there any standout brands or features worth paying extra for?
Brands like Feit Electric, Hampton Bay, and Brightown are widely available at home centers and online, and they generally offer good value for typical patio use. Feit’s G40 LED bulbs, for instance, have a strong reputation for consistent warm light and decent weatherproofing. Brightown makes popular budget sets with a range of bulb sizes and color options. What separates a great set from an average one are features like a low‑profile flat plug (fits behind furniture), a built‑in dimmer, or a remote control for color‑changing LEDs. Some premium sets use copper wire and hand‑blown glass bulbs, which look beautiful but cost much more and require more careful handling. If you plan to leave lights up year‑round, investing in a set with UV‑stabilized materials and a five‑year warranty can save you replacement headaches down the road.
Frequently asked questions
Can I leave outdoor string lights up all year?
Yes, but only if the lights are rated for permanent outdoor installation (look for a warranty or description that says “year‑round” or “all‑weather”). Even then, extreme sun and cold may shorten the lifespan of the bulbs and wire. Many people take down lights after the holiday season or in harsh climates to make them last longer.
How do I connect multiple strands?
Most outdoor string lights have male and female plugs on each end so you can link them end‑to‑end. Check the manufacturer’s limit, usually 3 to 10 strands depending on the wattage per strand, and never exceed the total wattage printed on the light string. Use an outdoor extension cord with a capacity to match for long runs.
What's the difference between patio lights and cafe lights?
The terms are often used interchangeably, but “cafe lights” usually refer to a specific style with larger, classic bulb shapes (like G40 or S14) held by a plastic or metal socket, commonly seen in restaurant patios. “Patio lights” can describe any outdoor string light, including smaller Edison bulbs or globe bulbs. For most homeowners, the two are the same thing.
How do I know if my string lights are UL listed?
Look for a UL mark on the packaging or on a tag attached to the cord. UL (Underwriters Laboratories) and ETL are two common safety certifications for North America. A certified set has passed testing for fire, shock, and weather hazards. Avoid lights that don’t carry any certification label, especially if you plan to use them outdoors.
Can I use indoor string lights outdoors?
No, not safely. Indoor lights lack the weatherproof seals, UV‑resistant insulation, and grounding required for outdoor use. Moisture can enter the sockets and cause shorts, shocks, or fires. Always look for lights specifically labeled “indoor/outdoor” or “suitable for outdoor use.”
How do I replace a bulb in a string light?
First unplug the set. Most string lights use screw‑in or push‑and‑twist bulbs that can be removed by hand or with a gentle tug. If a bulb is broken, wear gloves and safely remove glass pieces before replacing. Always use the same type and wattage as the original bulb, mismatching can cause overheating or damage to the socket.
