When choosing a trailer lighthouse (portable lighting equipment usually used for trailers or field operations), the following key factors need to be considered:

1.  Lighting requirements:

•  Brightness: Determine the required brightness (in lumins). Different working environments require different brightness, such as construction sites, emergency rescue sites, etc., which require high brightness, while activities such as camping may require relatively low brightness.

•  Beam angle and coverage: Ensure that the beam angle and coverage of the lighthouse are suitable for your use scenario. Some lighthouses provide adjustable beam angles to meet different needs.

2.  Power supply type and battery performance:

•  Battery types: Common battery types include lead-acid batteries, lithium batteries, etc. Lithium batteries are usually lighter, faster to charge and have a longer life.

•  Battery life: Select the appropriate battery capacity according to the usage time to ensure that the lighthouse will not be powered off halfway during work.

•  Charging method: Know whether the lighthouse supports a variety of charging methods (such as solar charging, AC charging, in-vehicle charging, etc.) so that it can be conveniently charged in different environments.

3.  Weather resistance and materials:

•  Protection level: Choose a lighthouse with a high waterproof and dustproof rating (such as IP65 or above) to ensure that it can work normally in bad weather conditions.

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

4.  Portability and installation method:

•  Weight and size: Portability is an important consideration for trailer lighthouses. Ensure that the lighthouse is of moderate weight and easy to carry and transport.

•  Ease of installation: Choose a lighthouse that is easy to install and disassemble. Some models provide foldable or retractable designs for easy storage and movement.

5.  Operation and control mode:

•  Control panel: Ensure that the control panel is easy to operate, including switches, brightness adjustment and other functions.

•  Remote control function: Some lighthouses provide remote control, which is convenient for remote operation and adjustment.

•  Intelligent sensing: The lighthouse with light control or human control induction function can be automatically switched on and off to improve the convenience of use.

6.  Additional functions:

•  Multi-light head design: Some lighthouses are equipped with multiple lamp heads, which can independently adjust the angle and brightness to meet the lighting needs in different directions.

•  Backup power output: Some lighthouses are equipped with USB interfaces or other power output interfaces, which can be used to charge other devices.

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 the above factors, you can choose the trailer lighthouse that best suits your needs and use environment.
