The key component of all HID ballast is the “controller” which control all functions of the ignition & lamp steady state procedure. The “controller” decide the quality level.

There are two kinds of controller used inside the ballast :

1. CPU controller　　2. ASIC controller

describe as follows:

1.CPU controller : All the HID Ballast made in china or Taiwan use CPU programming controller , the program is easy to copy ,and now you may spend us$3,000 to buy the CPU ballast total solution in GuangZhou HID market , therefore any engineer could make a ballast in his living-room ,so that rapidly creating many hid makers in China , and offer very cheap price inorder to get more orders. but a CPU controller can't monitoring the HID lamp (lamp power keep changing month by month ), and the lamp become more difficult to control,then bulb go off or CPU program out of control to burn out the ballast.,the defect rate is higher,and the ballast life is short.

2.HYLUX's ballast uses ASIC chip controller which is without program inside, only HELLA & Matsushita use this analog type inside of HID ballast in the world Asic chip is difficult to design and cost expensive, Hylux spend about us$600,000 to develop it which is with powerful functions of real-time lamp-monitoring & power compensation and Ballast protections . throught many reliability tests to obtain good quality.
Now Hylux has sold over 3,000,000 pcs ballasts all over the world, Under 0.5% low defect rate & over 3 years ballast life will increase your HID market share, so,Hylux belive that Good quality is the best service.
