2. Solar Panel

• Type: Most solar road studs use monocrystalline or polycrystalline solar panels, with monocrystalline being more efficient.
• Power Output: Typically ranges from 0.2W to 0.5W, depending on the size of the road stud and the intended light output.

3. Battery Capacity

• Type: Lithium-ion or Ni-MH (Nickel-Metal Hydride) batteries are common due to their charge/discharge stability and lifespan.
• Capacity: Usually between 500mAh to 1500mAh, depending on the required operating hours and brightness.

4. LED Light Source

• Brightness: Varies from 2000 to 3000 mcd (millicandela) for visibility in different light conditions.
• Colors: Standard colors are white, yellow, red, green, and blue, depending on usage (e.g., yellow for lane dividers, red for stop signals).
• Lifespan: Typically rated for 100,000 hours, ensuring long-term performance.

5. Lighting Mode

• Steady: Constant light, used for continuous visibility in high-traffic areas.
• Flashing: Blinking lights to draw attention, often in warning zones or accident-prone areas.
• Automatic Activation: Equipped with sensors to turn on at dusk and off at dawn, optimizing energy usage.

6. Operating Time

• Charging Time: 6-8 hours under direct sunlight.
• Working Time: 48-72 hours on a full charge, depending on battery capacity and LED brightness.

7. Waterproof Rating

• IP Rating: Most solar road stud lights are rated at IP68, providing resistance to dust and water, suitable for use in rainy or high-moisture conditions.

8. Dimensions and Weight

• Size: Generally between 100-150 mm in diameter for round studs or similar dimensions for rectangular studs.
• Height: Typically 15-25 mm above the road surface for proper visibility without causing disturbance to vehicles.
• Weight: Varies from 200g to 500g depending on material and design.

9. Impact Resistance

• Solar-powered road studs are typically designed to withstand pressures up to 20 tons, making them suitable for use on highways and heavy-traffic areas.

10. Temperature Resistance

• Many models can operate in temperatures from -20°C to +80°C, ensuring functionality in diverse weather conditions.
