i-Zombie Lightning Controllers are only made to operate on 120v. You would need to get a step down transformer to convert 230v to 120v. You should get a transformer that is rated 40-50% higher than the total lamp wattage you plan to use to compensate for inrush current. I have seen them offered on Ebay Australia for around 60 dollars for a 1000 watt unit. Somewhat more for larger capacity units.
You would also need to use 120v light fixtures and lamps. Audio kits with 120v components which include an MP3 player with the ThunderTracks already installed along with 28 watt powered speakers and two or four 500 watt halogen lights, depending on the kit, are available at Haunted Props. If you need a much louder sound, simply use a larger amp and speakers instead of the 28 watt unit. The i-Zombie Lightning Controllers come with a CD with the thunder sounds on it so you can use a CD player for your sound source as well.
