Ballast Performance

Ballast Performance - 12/28/04 02:52 AM

The data belows shown that the ballast performance from two different ballast manufacturer:

Ballast A
Incoming Voltage - 236
Ballast Voltage - 203
Lamp Voltage - 99
Lamp Current - 2.75
Lamp Power - 224
Incoming Power Consumption - 255
Illuminance (lux) - 12440

Ballast B
Incoming Voltage - 236
Ballast Voltage - 201
Lamp Voltage - 108
Lamp Current - 2.94
Lamp Power - 224
Incoming Power Consumption - 255
Illuminance (lux) - 12440

From the above result, two questions that I hope anyone can answer me:
1. Which one ballast is having better performance?
2. Does the current that supplied from ballast will affect the lamp life?
