Bulb spacing varies by style but commonly falls between about 3.5 inches and 8 inches.

Listed LED string wattages in the results range from about 2.4 to 6.7 watts, and descriptions commonly note LEDs use up to around 90% less energy than comparable incandescent bulbs.

Many sets emphasize outdoor durability with water-tight or molded connections, PVC or polypropylene construction, shatter-resistant (non-glass) bulbs, and UL certification for outdoor use.

Several sets include built-in clips at each bulb base or separate bulb-base clips to make it easier to attach lights to rooflines, railings, fences, or branches.

Some sets explicitly include replacement bulbs and spare fuses and note that bulbs are replaceable. Inclusions vary by product, so check the product details or packaging to confirm what’s included.
