What are the key points for purchasing solar lamps?

When purchasing solar lamps, you need to consider multiple aspects, including light source brightness, solar panel quality, battery performance, protection level, sensing function and brand after-sales service.

Light source brightness is an important indicator for measuring lamp performance. Usually, courtyard and garden lighting use lamps with moderate brightness, while security monitoring or driveway lighting requires higher brightness. The lighting time depends on the battery capacity and the charging efficiency of the solar panel. When purchasing, you need to pay attention to the lighting time of the lamp when it is fully charged and the working conditions on rainy days.

The quality of solar panels directly affects the charging efficiency and service life of lamps. High-quality solar panels have high photoelectric conversion efficiency, corrosion resistance, waterproof and dustproof characteristics, and polysilicon materials have a long life. Battery performance is also critical. Battery capacity determines the battery life of the lamp. More charge and discharge cycles mean longer service life. Lithium batteries are widely used in high-end solar lamps due to their high energy density and long life.

The protection level determines the applicable environment of the lamp. The IP (Ingress Protection) code indicates the dust and water resistance level. Garden lighting usually chooses lamps with IP65 or above, and IP67 or above protection level is required for underwater or humid environments. Intelligent sensing functions such as light sensing and human sensing can improve the user experience. The light sensing function automatically turns on the lamp when it is dark, and the human sensing function automatically turns on the light when someone passes by.

Choosing a well-known brand usually means better quality and more reliable after-sales service. Recommended solar lamps include Bull Solar Lights, Dengli Solar Lighting and NVC Solar Lighting, which have high-brightness LED lamp beads, intelligent light control, polycrystalline silicon solar panels and tempered glass, etc., which meet different needs, are durable and provide all-weather lighting.
