Thanks a lot, I never used 240v AC, do I need some sort of an adapter ?

It's clearly intended to run off the mains voltage. A battery won't work.

You'll have to connect it as shown in the documents, Neutral to blue wire, Live to brown wire and your load from red wire to Neutral (blue wire). Use a mains cord with a proper plug on one end and open wires at the other end. A simple (mains voltage) light bulb (shouldn't matter if incandescent, LED or CFL type) will do the job for testing.
If you want to run battery operated LEDs from this device, connect a wall wart or power brick to the output, the device will turn it on and off at the mains AC side, and connect your LED to the power supplies output.

Be careful if you don't have experience with mains voltage.

capt bullshot Thank you very much, will LEDs work with that kinda voltage ? I mean if the input is 110-220, whats the output ?

Have you had time to check the photos please?

Thanks
capt bullshot:
The output is the same as the input.
So this thing is working on a 240V AC input and ouputs nothing or 240V AC.
You cannot directly connect an LED to 240V AC, you'll have to use e.g. an LED light bulb rated for 240V AC or some kind of power supply that has 240V AC input and appropriate output for your LED.

Thank you very much, so I decided not to use that and get a 2A one from ebay,
Thanks everybody this thread is now closed :)
