Choosing the Right Bulb Size

  • Small bulbs (C3-C5): Best for decorative garden lights.
  • Large bulbs (C7-C9): Ideal for street and driveway lighting.

2. Brightness (Lumens)

Lumens comparison
Lumens determine the brightness level. Choose the right lumen output based on the application.

Recommended Lumens for Different Areas

ApplicationRecommended Lumens
Stair lights12-100 lm
Wall lights50-200 lm
Landscape lights50-300 lm
Small garden (50㎡)1600 lm
Medium garden (150㎡)2800 lm
Street lighting5000+ lm

Weather conditions and solar charging efficiency can impact brightness. Choose a solar light with good battery storage for consistent lighting.

3. Lighting Modes

Different lighting modes offer flexibility for various applications.

Common Lighting Modes

  • Dimming Mode: Ideal for relaxed night settings.
  • Motion Sensor Mode: Activates when movement is detected, enhancing security.
  • Color-Changing Mode: Great for decorative purposes.

Smart solar lights allow remote control and automatic mode switching, offering convenience and energy efficiency.

4. Solar Panel Type

Solar panel types
The solar panel affects energy conversion efficiency and durability.

Types of Solar Panels

Solar Panel TypeEfficiencyCostSuitability
MonocrystallineHighExpensiveBest for long-term use
PolycrystallineMediumAffordableGood for moderate needs
Thin-FilmLowCheapWorks in low-light areas

For the best performance, choose monocrystalline panels with a high conversion rate and durability.

5. Battery Type and Capacity

Batteries store energy for night usage and determine runtime.

Battery Type Comparison

Battery TypeLifespanCharging SpeedMaintenance
Lithium-ionLongFastLow
Nickel-CadmiumMediumSlowRequires maintenance
Nickel-Metal HydrideShortMediumMedium
Lead-AcidLongSlowHigh maintenance

For reliable operation, opt for high-capacity lithium-ion batteries with fast charging and long lifespan.

6. Additional Features

Smart solar lights
Extra features enhance usability and performance.

  • Motion Sensors: Improve security and save energy.
  • Timers & Dimmers: Optimize energy use and create ambiance.
  • Smart Connectivity: Remote control via mobile apps.
  • Color-Changing Effects: Ideal for decorative settings.

7. Durability and Waterproof Rating

Durability depends on materials and waterproof ratings.

IP Waterproof Ratings

RatingProtection LevelUsage
IPX4Splash-resistantBasic garden use
IPX6Resistant to heavy rainOutdoor environments
IPX7+Can withstand immersionExtreme weather conditions

For outdoor reliability, choose lights with at least IPX6 waterproof rating and rust-proof materials like stainless steel or aluminum.

8. Price Considerations

Higher price does not always mean better quality. Evaluate performance and features before purchasing.

Price vs. Performance Guidelines

  • Budget-friendly models: Suitable for decorative lighting.
  • Mid-range models: Balance between quality and cost.
  • High-end models: Best durability, brightness, and smart features.

9. Warranty and After-Sales Support

Warranty importance
Warranty reflects product reliability. Look for at least 1-year warranty from reputable brands. Reliable brands often offer longer warranties, ensuring product longevity and customer satisfaction.

FAQs
