Aluminum alloy is known for its excellent durability, strong impact resistance and long service life. On roads with heavy traffic, where crushing and impacts from vehicles are common, aluminum alloy solar road studs can easily cope with them, ensuring long-term stable operation and providing continuous and reliable guidance on the road.
Polycarbonate or high quality plastic
Polycarbonate or high-quality plastic solar road studs are lightweight, impact-resistant and cost-effective. In areas with moderate traffic flow or on high pedestrianized roads, this material is a cost-effective option to meet lighting and guidance needs while keeping costs under control.
Tempered Glass
Toughened glass solar studs offer high visibility and a stylish appearance. In high-end applications where the appearance of roadway facilities is critical, and in areas with low traffic speeds, tempered glass studs can provide clear guidance while enhancing the overall aesthetics of the roadway.
High Intensity LED Lights
High-quality solar studs typically utilize powerful LED lights that emit light with an intensity of 3000 - 4000 millicandelas (mcd). This high level of luminosity allows the solar stud to be clearly seen from a distance of up to 800 meters. This gives drivers plenty of time to react at night or in bad weather.
Multiple color options
The solar road studs are available in red, yellow, white and blue colors. Different colors have different functions, red is often used to warn of dangerous areas, yellow can be used as lane separating signs, white is used for normal lane guidance, and blue may be used in specific occasions (such as emergency access instructions), through a rich combination of colors to effectively guide traffic.

A traditional reflective cat's eye (passive stud) relies solely on its reflective properties to illuminate the roadway. It requires no solar power or batteries and is low cost. However, its illumination effect is only visible when illuminated by an external light source (e.g. vehicle headlights) and does not provide illumination in the absence of an external light source. This type of stud is suitable for areas where the need for continuous lighting is not high.
Active Lighting
For areas with high traffic volumes or where additional lighting is required, active solar studs with LED lights are a better choice. With multiple modes of flashing, constant or synchronized blinking, these studs provide greater visibility for vehicles and pedestrians, even in low light conditions, effectively improving road safety.
Polycarbonate or Aluminum
The material of the stud is critical to its durability. Polycarbonate is UV and scratch resistant, making it suitable for outdoor use. Aluminum alloys, on the other hand, are more resistant to corrosion and can withstand higher loads, which is essential for heavy traffic scenarios such as freight lanes.
Load-carrying capacity
Depending on the application, the load-bearing capacity of the stud needs to be considered. For example, when installing solar studs in heavy traffic areas or on roads with heavy vehicles, choose a product that can withstand up to 50,000 pounds. This is especially important in scenarios such as highways or truck-only lanes.
Solar Panel Power
Choose studs with high-efficiency monocrystalline or polycrystalline solar panels. Commonly available solar panels range from 0.5W to 1W, which allows them to charge efficiently even on cloudy days, ensuring that the stud works properly.
Battery Life
Always check the battery capacity (e.g. 3.2V 3000mAh) as this determines how long the stud will be illuminated. A good quality solar stud will last for 10 - 20 days when fully charged, depending on the lighting mode.
Warm white lighting for decorative paths
Warm white lighting is ideal for decorative paths such as cherry blossom gardens or holiday event areas. This soft hue complements the natural landscape, creating a warm, pleasant atmosphere and enhancing the aesthetics of the environment.
Multiple Color Options
Solar Road stud offers a variety of colors such as white, yellow, red, blue and green to meet different needs from safety warnings to decoration, providing flexibility for various application scenarios.
Installation
Installation of solar studs is relatively simple. For surface-mounted studs, the installation process is easy and can usually be accomplished with basic tools. Recessed designs require more manual labor, but provide a cleaner, low-profile appearance.
