The standard UK 3-pin power adaptor from biOrb is used for powering the light unit and air pump on any biOrb Aquarium.
The Reef One range of aquariums is designed to be extremely safe and therefore all its electrical items operate at the safe low level of 12 volts AC. To protect the fish-keeper and children from electric shock. Reef One aquariums use a plug top AC transformer that plugs into your electrical mains socket and steps down the mains voltage to a much safer 12 volts AC.
The 12 volts is made available in the bottom of the AC transformer through two DIN sockets (see image). Either socket can be used for the halogen/LED light wire plug or the air pump wire plug as both sockets are interchangeable. The LED light if used in place of the halogen light can be plugged into either socket.
