The only way your are going to get 3 times the current is if you reduce the voltage by 1/3 which means your lights are going to be very dim. This box appears to be a transformer with 2 duplex receptacles mounted on it. I would like to see how its wired. A 20A 120V circuit is rated for 2400W max and there is really no way you are going to get more out of it. I would love to have something like this for my entire house to reduce the utility bill to 1/3 of what it is now. It will be interesting to see what others have to say.
