My apologies as this is very much not linux and not even computer

I have 2 LED light on my Fish tank and one of the power supplies is
dead. Getting a replacement power supply from the supplier is not an
option, no longer available.
The only technical detail I can tell you about the power supply is
that it is DC 12v 47watt output, there are two switches on the Power
supply which operate two modes on the light. I normally leave both
switches on so the light in full on mode and is permanently switched
on and is controlled via a time switch (one for each light), so
having the two switches in not that important (to my thinking below).
The output plug is a small round three pin affair which makes me
think that there are two live cable and one neutral cable. On the
assumption that this is correct, would getting a replacement power
supply like a DC 12v 60w then cutting the supplied output plug off
(which in most case is the two cable round push in plug.), then
having cut the old output lead off the old power supply, solder the
two lives to the single live on the new power supply and then the
neutral to neutral. Would this work? I realise there is a bit of
investigation to do first but just trying to think of possible
options in getting a replacement (I have tried ebay).
Any thoughts

Just my thoughts: It sounds like a lot of power for LED lights.
It is one power supply driving two lights/bulbs.
Can you swap the bulbs round to check that it is not the light that
has gone?
Assuming that you can open it up (Unplugged of course) can you check
that there is not a fault in one wire, or in the switch? Of course,
as it is for use near water it could be a potted power supply and
inaccessible inside.
I found this at 'lightinthebox.com It might be a cheaper overall
option? Aquarium Light LED Light Fish Tank Light White With Switch(es)

Hi Pete
Its two lights and two power supplys (of which one power supply is
dead), both light work already tested with working power supply. Have
looked at the dead power supply (you can take it apart) but nothing
looks out of place.
The LED lights are just over 4ft long with three rows of LED's (it is a
5ft fish tank) so I guess 47 watt was the design wattage. There is a
long lead from the light about 5ft and then a small pig tail from the
power supply which then screw together with a male female round three
pin plug\socket. There is a small pig tail of about 15" inches which is
hard wired to the Power supply for the 240v mains.
