How much should you spend on outdoor Christmas lights?

The short version

• Most people need plug-in LED strings marked for outdoor use, with a red UL mark and a timer.
• A basic LED string costs $12.35 to $18.99, and a timer, clips and a cord add to that.
• Skip paying extra for bigger bulb life or flicker-free claims.

Which kind fits you

For a roofline, trees and fence lines, plug-in LED strings are the usual answer. They need an outlet or an extension cord, but you never worry about batteries or sun. Bob Vila reports that LEDs made up over 90 percent of string light sales in 2024.

Bulb shape is mostly about look. C6 and C7 are bulb sizes and shapes, and sellers describe both as suited to trees and rooflines. The C7 is described as having warm, incandescent-like tones.

If you want the cozy glow of old bulbs, incandescents are typically cheaper and warmer, but they burn out faster and use much more electricity. Some people find LED light harsh and cool, so look for a warm white label.

Solar suits a small, sunny spot, and a big display could look cluttered with many panels. Battery suits a spot with no outlet, but battery life ranges from a few hours to over 100 hours.

Features to look for

Check the tag for a red UL mark. Red means indoor and outdoor use, and green means indoor only. Bob Vila advises using only UL-listed lights. Outdoor-rated lights also have thicker wiring and tougher materials.

Next, look at how many sets connect end-to-end. Only about three incandescent strings can usually be linked, while LED strings link far more. One listed C7 string connects up to 90 sets, and a C6 string from the same seller links up to 45. That decides how many outlets and cords you need.

It also helps if the rest of the string stays lit when one bulb fails. One listed C6 string does this.

Last, glance at the watts, which is how much power the string draws. Lower uses less. Listed strings range from 2.4 to 4.8 watts.

Upgrades worth paying for

A timer is worth it for almost everyone, since you won't have to remember to switch the lights on. Outdoor timers are listed from about $15.73 for a mechanical one with a photocell (a sensor that turns lights on at dusk) to $30.14 for a 6-outlet digital one with a remote. The photocell suits you if you want to set it and forget it. The remote suits you if you run several strings from one spot.

Clips are worth it if you hang lights on a roof edge and don't want to rework them each year. Adhesive clips for flat surfaces cost $10.35 for 100, and flip clips for shingles and gutters cost $8.53 for 75.

Plug protectors for light connections cost $5.10 to $25.22. They suit you if connections sit on wet ground or snow. An 8 ft outdoor 3-outlet cord costs $13.83 and suits you if several strings start in one spot.

A longer warranty is worth it if you plan to reuse the lights for many years. Some makers back sets for several years, and one lists 3 years. An ENERGY STAR label, which marks energy-saving products, is a bonus for the same reuse-it-for-years shopper.

What you can skip

Skip paying extra for a bigger bulb-life number. LEDs can last upwards of 50,000 hours, which is far longer than most people will ever run them, so a basic LED string already covers it.

Skip the flicker-free claim. Some mini strings advertise steady light, but a basic LED string covers everyday use.

Skip a huge connect-end-to-end count unless you need it. Listed strings link 45 to 90 sets, which is far more than a typical house front needs.

Skip the long heavy-duty extension cord unless your outlet is far away. A short outdoor cord does the job for most roof lines.

What you get for the money

Around $12.35 to $18.99 gets you a basic LED string. Examples include a 17 ft C7 string with 25 bulbs at $12.35, a 24 ft C6 string with 70 bulbs at $17.40, and a 240-LED connectable string at $18.99. A 300-bulb incandescent mini string is $9.98, but it burns out faster.

Around $44.99 is the step up we could price. One 25.5 ft, 50-light LED set at that price is UL listed and ENERGY STAR certified, with a 3-year warranty. It is one example, so treat it as a rough marker. Sets with more bulbs already show up in the basic range, and we found no higher tier with enough prices to list.

The real budget is the extras. A timer runs $15.73 to $30.14, clips $8.53 to $10.35, and plug protectors $5.10 to $25.22. Bob Vila notes that LEDs cost more upfront, but lower utility bills and fewer replacements can offset it.
