We improved the illumination for a supermarket in Italy in August, 2011. As LED lights in the supermarket work for quite a long time during the daytime, they must be energy saving, have high luminous flux and lifespan. Based on the requirements of the customer, we developed a power supply circuit by ourselves, which has excellent heat dissipation. We combined the drive circuit and high-brightness LED lamps into a product and added a new member for our T8 series. The new T8 LED light achieves a power factor of more than 0.95 and consumes 55% less of electricity than old lights. It was highly appreciated by the customer, who then used the product in its 2 supermarkets. The customer still had several dozen of chain stores that were using old style lights. The owner had decided to use our LED lights to replace all the old ones.
