led street lights problems, failure of projects in Nanjing

In China, we start a lot of new lighting products, try to replace the CFLs by LED  Lights, technically it’s a good plan, but it’s very differet to be realized.

In 2010, some other led company do a demo project in Nanjing, try to replace all the HID Lamps by led street lights, at that time, the price of led lights are  about 1000 USD, and the price of HID lamps are about 350 USD. 170 units of led street lights were installed,  but 2 years later, LED street lights problems happened, 80% of them are not working.

So, why the led street lights problems happened? During the 2 years, the LED company replace all the LED Drivers, but the lamps are still stop working one by one.

Actually,  the led street lights problems already a big problem for LED street lightcompanies.  As we all know, the power supply and led chips are the 2 problems for the lifespan. Till now, some led companies already succeeded in small LED products, like LED Spot Lights, but the big led lighting, even outdoor LED Products would be very difficult to design for most of the LED Companies.

I’ve ever talked to the Chief designer of Eneltec (top LED High Bay company), the reason why all the LED products of Eneltec offer a 2 years warranty, and the fail percent would be under 0.3%, are just because we use the best materials, best components. To improve sales turnover, all the LED Companies want to reduce the cost of products, but we should not save the cost by low level materials and components.
