Company Information



1.Q:How to use our lights?

  A:The light battery is on sleep before delivery in order to avoid discharging during transportation. You need activate accordingto the installation manual.

2. Q:How to install our lights?

  A:Fix the product with a right angle and make sure no shelter on the surface of solar panel.

3. Q:How long is the all in one solar street light charge time?
  A:All of our solar LED light charging time is 8 hours in strong sunlight.

4. Q:What to do with the rainy day or Cloudy day?

 A:The outdoor solar light is waterproof. You don’t need to worry about it. After fully charged, the capacity of battery can keep the LED working in several rainy/ cloudy days.

5. Q:If you found the light brightness is down or total off, how to handle?

  A:It proves the power of solar light battery is not enough to support normal lighting, so you need have 2-3 goods sunlight charging, especially in Winter season, the sunlight intensity is much below the standard sunlight (1000kw/m2), it may need more longer time for charging. 

6. Q:What is the warranty for our light?
  A:For all of our lights, we provide 5 years warranty for whole set as we used the best quality LiFePO4 lithium battery, which is also used in electric bus, lifespan is 8-10 years.

7.Q:What is the terms of payment?
  A:T/T, L/C,western union, trade assurance or cash; 30% for deposit, the balance 70% before shipment for bulk order.

8.Q:How about the after sales service?
  A:Blue Carbon welcome you contact us at 24 hours per day, 7days per week,your any questions will be highly appreciated. Contact hot-line:+86-633-2190373
