At present, the quality of LED lighting market is not so stable. To save the costs, Some of them prefer sacrifice product quality. Replace ADC12 Aluminum with ADC7 aluminum ingot.


And the heat dissipation is extreme, there is not extra reserved to ensure heat dissipation.


In order to save the cost of LED Chips, Some of them use poor quality LED Chips with poor heat dissipation performance,which will  cause a big light decay. the color temperature will be changes and vulcanized.


The use of non isolated LED power supply, the core component of LED lights, has used certified power supply during testing, but can not use certified power supply when producing in large quantities, which is a serious violation of business ethics.


All aluminum materials that ZISTELED used for LED Highbay, LED Floodlight, LED Streetlight etc all Die-Casting product, We all use ADC12 national standard aluminum ingots with sufficient heat dissipation allowance. Ensure that the lamps can works good in different application.


In order to achieve the light effect specified by customers, we use famous brand LEDs and reduce the current. The power will only reach about 50% of the rated power to ensure the efficiency and light decay of the LED Chips/
 
LED power supply, as the core component of LED lighting , usually we will use famous brand power supply as the first choice. If the customer's project budget is limited, we will consider using the power supply with verified quality to ensure that the lamps work good within the warranty period.
