Hi it is a little but off the topic of this forum but it is for led for my tank so hoping someone has same type of plug. I am looking to buy a second power supply adapter. Thankyou any help would be appreciated. I am from australia this is not a common fitting. Cheers!

In the airplane world that would be a 24V DC cannon plug. Not sure about the aquarium, but I would check that out.
