Is it possible to see the state of the LED (ON/OFF) with a DigitalInput Phidget?

Can you explain what the differences are between the Light Phidget and Light Senor 1000 lux?

Is it possible to flash a device by using Phidgets? I think I should use a 4x Relay Phidget to do this. But I don't know how to start.. I'm kinda bad at programming. I was planning to use Python for this.
