The addlon 52ft Solar String Lights is a patio and outdoor ambiance lighting set designed for backyards, gardens, and camping trips. It's aimed at buyers who want a substantial, feature-rich string light setup that goes beyond basic on/off functionality, without needing to run any wiring.
The standout feature set includes a combination of remote control, USB charging, and shatterproof bulb construction, which together set it apart from more basic solar string lights. The included remote allows users to switch between the 3 available light modes and adjust dimming levels without needing to walk over to the light strand itself, which adds real convenience for larger patio setups or when lights are strung across a wider area. The built-in USB port is a useful bonus, letting the unit double as a small charging source for devices when needed.
At 52 feet total length, split between a 48ft main lighting strand and a 4ft lead wire, this set offers enough coverage for most backyard, garden, or camping layouts without needing to link multiple sets together. The 16+1 shatterproof LED bulb design also adds a practical safety and durability advantage over traditional glass bulb string lights, particularly relevant for high-traffic patio areas or family and pet-friendly spaces.
This product's strong sales and review history, with over 11,000 ratings and a 4.2-star average, reflects consistent buyer satisfaction across a wide user base, lending confidence in its real-world reliability for everyday outdoor use.
The main trade-offs are relatively minor. The 3-mode selection, while functional, is more modest than some string lights that offer 5 or more lighting effects, and as with any solar product, actual brightness and runtime will depend on how much direct sunlight the panel receives. The remote also introduces one more battery-powered component to maintain over time.
Overall, this is a well-rounded, dependable choice for buyers wanting generously long, safely built solar string lights with meaningful remote and USB functionality, backed by a strong review history that supports its real-world performance.
When shopping for solar string lights, length is one of the first specs to match against your space. A 52ft set, like this addlon option, works well for larger patios, full backyard perimeters, or extended garden layouts, while shorter 20-30ft sets suit smaller balconies or single tree wraps.
Bulb material matters more than it might seem. Shatterproof LED bulbs, as used here, hold up better in high-traffic outdoor areas and around kids or pets compared to traditional glass string light bulbs, which can break and create a safety hazard if damaged.
Remote control is worth prioritizing if your string lights will span a wide area, since it lets you change modes or dim brightness without walking the full length of the strand. For shorter, easily reachable setups, a simpler button-operated set may be sufficient and slightly cheaper.
Extra functionality like a built-in USB port can add real value beyond lighting alone, particularly useful for camping trips or outdoor gatherings where a backup charging source is handy.
Finally, when comparing solar string lights, review volume and rating consistency, like this listing's 11,000+ ratings at 4.2 stars, is a strong signal of real-world reliability across a large number of buyers, and can help you feel more confident about performance before purchasing.
Costco Solar String Lights Buying Guide for 2026
When shopping for costco solar string lights, you need to consider several factors to ensure you get the right fit for your outdoor space. We’ve broken down the key criteria to help you make an informed decision.
Brightness and Light Output
Brightness is measured in lumens. For ambient lighting, look for string lights that offer at least 10-20 lumens per bulb. Some models like the Brightech Ambience Pro provide 1W per bulb, which is equivalent to about 10-15 lumens. For tasks like cooking or dining, you may want brighter options. Many solar string lights now come with dimmable settings, allowing you to adjust the brightness from 25% to 100%.
Battery Capacity and Runtime
The battery capacity determines how long the lights will stay on after sunset. Most good solar string lights offer 6-12 hours of runtime on a full charge. For example, the addlon 100FT model has a 5500mAh battery that can last up to 25 hours. Look for models with high-capacity lithium-ion batteries and USB charging backup for cloudy days.
Solar Panel Efficiency and Charging Options
The solar panel is the heart of the system. Larger panels with higher efficiency (monocrystalline) charge faster. Many models now include dual charging via USB, which is a lifesaver during extended rainy periods. The Minetom 100FT lights, for instance, can be fully charged in 4 hours via Type-C USB.
Durability and Weather Resistance
Outdoor lights must withstand rain, snow, wind, and temperature extremes. Look for IP65 waterproof rating or higher. Shatterproof plastic bulbs (like PET or PC) are safer than glass. The Brightech Ambience Pro line is tested to withstand winds up to 50 MPH and temperatures up to 122°F.
Length and Number of Bulbs
String lights come in lengths from 23 feet to 200 feet. Consider the area you want to cover. For large patios, a 100FT or 200FT set is ideal. The spacing between bulbs also matters: typical spacing is 1.6 to 3 feet. Some models like the addlon 100FT have 54 LED bulbs with 2-foot spacing.
Smart Features: Remote, Timer, and Light Modes
Modern solar string lights often include a remote control for convenient operation. Look for multiple light modes (steady, breathing, flashing), adjustable brightness, and timer settings (2, 4, 6, 8 hours). The plosim 50FT model even offers stepless dimming. These features add versatility and energy savings.
