Founded in 2009 by a previous college dropout, now the CEO David Chen, ThruNite is an on-going dream. He dropped out to pursue his dream in south China but met all setbacks. But he kept learning and tempering himself to become an expert of LED products which he saw great potential.

When he started to fight for his dream, he named it ThruNite, which is short for “Through Night” to define the company as a business helping people living easier lives with affordable and quality products. Thus comes the famous brand motto: ThruNite, guiding you through the night.

David, the dreamer who will fight with all his life to make ThruNite an on-going dream accessible to everyone. The company’s establishment on August 6th, 2009 was the beginning of his journey. As a result, he made Thursday as ThruNite Day to remember the original intention of this business, celebrate the current success as well as a chance to communicate with the customers. This is the origin of ThruNite Thursday.


Development and Current Landscape

First established in Dongguan, Guangdong, ThruNite moved to Shenzhen, the most dynamic city in China with a vision to the whole world two years later. To cut down the cost, it attracts all talents for R&D, manufacturing, sales and service to do everything on its own and go beyond B2C to M2C.

Just as its simple but graceful product concept, ThruNite sticks to make things simple and effective. Working with the biggest online shopping platform Amazon and cooperating with the most efficient logistics systems as Amazon, Fedex, TNT and DHL, ThruNite now offers fast delivery from localized Amazon warehouses in United States, Canada, Japan, Germany, UK, France, Italy, Spain and China.

But ThruNiters will never be satisfied if one of their customers is not satisfied. Thus, overseas localization is their ambition to provide better service while continuing upgrading the products. A brand new website of multi-language and multi-currency is coming up. New products designed on the basis of high quality and affordable price are being launched every two months on average. Worry-free before-and-after-sale-service is always available at online chat or Warranty of 30 days free replacement unconditionally,Free 24 months replacement and lifetime limited warranty asking only for cost of parts and freight are sincere beliefs from ThruNiters’ confidence and proud.



ThruNite is and will always be holding fast to offer affordable quality products and satisfactory service to make your life easy. Sure there is still a lot to do though, we are on our way.


ThruNite, guiding you through the night.
