Thank you all for your replies. Just to cover some of your questions
Before I bought the lights I checked with the company whether they would be okay to use in the UK and they said "The lights will work in the UK but you will need to change the plugs or use an adapter", which brings me to asking how to rewire them to a UK plug.
I did hope they would be "kettle leads" as that would mean I'd simply have to change them for UK 3-pin ones, but the lead goes inside the housing of the light so this isn't the case.
I have rewired plugs before, I've just never converted 2-pin to 3-pin before (and didn't know if you can) and there doesn't seem to be much about it on the internet so I wanted some professional advice.
Please see the attached photos
The photo shows this as being a French plug top, not the German Shuko which has a scrapping earth. The French system has a protruding earth pin at the socket outlet that enters the plug top as it's inserted into the outlet. Also the German plug tops are NOT polarised, the French plug tops Are. (but can still be used in a German outlet in an unpolarised form) !! ...lol!!!
Just cut the French plug off and replace with the UK, using Rockingit's sketch if your unsure how!!!
