UPDATE:

Today I received a letter from Screwfix regarding these LED floodlights.

Apparently they are an electrocution risk if oval cable such as T+E is used and that this should be swapped for ROUND cable or the rubber O ring fails to seal.

apparently the manufacturers (LAP) omitted to put this information into the installation leaflet.

So that means that people will have to put a water proof junction box on the wall, put a short length of flexible round cable on the light fitting and then use the junction box to connect the ends of the T+E and the round cable together.

This could have all been avoided if LAP had put the cable entry point at the bottom of the light fitting, not at the top...

Grrrrr
