Bryan, you've heard it a dozen times in as many different fashions. You plugged a 120v 60 hz device into a 220/50 grid.

You're very lucky that you've not fried more equipment than just those two items. The pump probably functioned longer due to the simple nature of the pump, the lights have probably a blown fuse or worse, several blown components on the power board.

I believe that you are fortunate that Hagen will honor their warranty as I would not. Not for an operator induced fault.

The root of your problem isn't the equipment, since you janked that all on your own, it's with the customer service you've received.

From my position here it looks as if you've been treated very well by the LFS. And because Hagen hasn't responded in a week doesn't mean that they've forgotten you.
