When choosing a solar lighthouse, you need to consider the following aspects:

1.  Lighting requirements:

•  Brightness: Determine the required brightness (number of lumins) according to the use scene. Low-brightness lighthouses can be selected for small areas such as gardens and paths; high-brightness lighthouses are needed for large areas such as squares and docks.

•  Irradiation angle: Ensure that the light coverage meets the needs, and some lighthouses provide adjustable angle lamps.

2.  Solar panel performance:

•  Conversion efficiency: high-efficiency solar panels can be fully charged in a short time. Generally speaking, the conversion efficiency of polysilicon and monocrystalline silicon solar panels is relatively high.

•  Solar panel size: Large solar panels can usually capture more light, but require more installation space.

3.  Battery capacity:

•  Battery life: The battery capacity determines how long the lighthouse can continue to work when there is no sunlight. Choose the appropriate battery capacity according to the length of use at night.

•  Charging time: Understand the time required for the battery from full discharge to full charge to ensure effective charging in daily use.

4.  Weather resistance and materials:

•  Waterproof and dustproof level: Choose a lighthouse with IP65 or higher protection level to ensure that it can work normally under various weather conditions.

•  Material quality: High-quality materials (such as aluminum alloy, stainless steel, etc.) can improve the durability and corrosion resistance of the lighthouse.

5.  Control mode:

•  Automatic induction: The lighthouse with light control and human control induction functions can be automatically turned on when it is dark to increase the brightness when a person is detected.

•  Manual control: Some lighthouses provide manual switches or remote control functions, which can be flexibly controlled as needed.

6.  Ease of installation:

•  Installation method: choose a lighthouse with different installation methods such as ground plug-in, wall-mounted or column installation according to the actual installation environment.

•  Installation tools and instructions: Make sure that the lighthouse comes with the necessary installation tools and detailed installation instructions so that users can install it by themselves.

7.  Brand and after-sales service:

•  Brand reputation: Choose a brand with good reputation and quality assurance to ensure product performance and after-sales service.

•  Warranty period: Understand the warranty policy of the product so that you can get timely support when you encounter problems.

Based on these aspects, you can choose the solar lighthouse that best suits your needs.
