This led light electric parameter testing digital demo case has 2pcs 6 in 1 meters A and B . Each meter can show you the light input voltage,input current,power consumption,power factor,anual power consumption(dayly working time adjustable) and anual electricity charge. 
1.A meter can show the A zone AC working light parameters.B meter is for B zone light testing and demo. Middle one is for DC light parameter show.You can light up 2 same socket lights at A and B working area,and their performance electric parameters will be directly shown on A and B meter.The comparation between 2 lights are obviously. 
2.Each light socket has a individual switch to control. 
3.There are 0.6m LED T8 tube light and traditional fluorescent T8 tube light fixtures below the meters.This design can show how much power will be saved by LED light than the traditional one. 
4. DC light electric parameters can be displayed on the DC multi meter. 
5. There is a dimmer to introduce the dimmable lights parameters changing. 
6. There is a external driver LED light testing special area on the right side.It can practice AC to DC transfer through a external driver to show the light performance. 
7. The AC and DC plug seat are set on their own zone.You can use them in AC and DC power supply. 
8. The main power control center is on the left side.AC110V and AC220V can be transferred by the switch as per your local voltage.The isolation transformer ensure the tester safe to people. 
This digital light Electric Parameter demo case can work as a LED light power supply,light tester,LED light show case, power consumption saving demo.
