  • Integrated Units: The solar panel, battery, and LED are all housed in a single unit (e.g., portable lanterns, pathway lights).
  • Remote Panel Systems: The solar panel is separate from the light bulb and connected by a wire, allowing for flexible placement.
  • Decorative Lights: Designed for aesthetic purposes, like string lights or garden accents.
• For each type, provide:
  • A description of its typical application.
  • Pros and cons (e.g., portability, ease of installation, brightness).
  • Example product images.

4. Key Features to Consider: The Buying Criteria

• Use a table to clearly present the most important features and their significance:

  Feature	Importance	Description
  Brightness (Lumens)	High	Determines the amount of light produced. Match lumens to the intended use.
  Battery Capacity	High	Affects the runtime of the bulb. Choose a capacity that meets your lighting needs.
  Solar Panel Size	High	Impacts the charging speed. Larger panels generally charge faster.
  IP Rating	Medium	Indicates water and dust resistance. Essential for outdoor use.
  Build Quality	Medium	Determines durability and lifespan. Look for weather-resistant materials.
  Light Color Temperature (Kelvin)	Low	Warm or cool light. Select to suit your preferences and usage conditions.
  Warranty	Low	Provides protection against defects.

• Elaborate on each feature, explaining:

  • How it affects the performance of the solar panel light bulb.
  • What to look for in terms of specific values or ratings.
  • How to choose the right feature based on your needs (e.g., if you need bright light for a large area, prioritize higher lumens).
