I've installed a couple of floodlights to replace an old halogen unit.

Neither work. The first dimly lit approx. 40% of the LED array and the other one does nothing.

They're run off a fused spur and there is power to each unit as tested with a volt pen.

I've tested the first with a 3 pin plug and it works fine so doesn't appear to be the unit itself. I'm guessing there's an issue with the wire from inside spur to outside.

Any suggestions?

Get a cheap voltmeter & test the voltage you are getting at the device would be a start.

There are some pretty poor quality units around. If you can wire something else to the spur and it works then you probably have the answer.

Make that 'voltages'.
Could be a neutral fault.

Try loading it with a conventional light bulb and checking L-N, L-E, E-N

Are there any 'clever' timers, PIR sensors etc etc in the equation?
