Outdoor light not working

I have a light in the garden that has just stopped working. I replaced the bulb, nothing. I replaced the light fitting, nothing. I got a volt tester and tested the wires. The live wire reads 240v, but the neutral only 120. Does anybody have any idea what the issue might be?

120 to neutral is normal on a 220 circuit. I'm not sure why they have a neutral line run unless there's a 110 circuit as well. A 220 light is probably going to have a ballast and you might be better off getting a more efficient light if the ballast is out.

Thank you for reply, but I am not sure if that has answered my question. If it did, then I didn't understand. The light is simply not working and it used to

If this is residential, there is a wiring problem(sometimes best to call a pro) or you are measuring incorrectly. Check your multimeter settings. Residential wiring is typically 120 for lights and outlets, 240v for appliances.

What did you use to test for the presence of power ?

For the neutral to have 120v on it suggests that it is a 240v feed,
In which case there should be 120v on both lines,
With respect to neutral/ground.
If this is the case, then it would suggest that you have lost
one of the two hot feeds.

You should test backwards from the light, to find where it's going amiss.

The other possable is you are reading a phantom voltage.
Non contact testers and digital meters can give false readings.
To know for sure, put the voltmeter on the line, observe the reading,
then put a load on the line, like a lamp, if the reading goes away,
then it's a phantom voltage.
