just an update , i emailed lightforce to complain about the poor quality of the wiring and the problems iv'e had and they told me they have had quite a few complaints and they were sorry, they sent my email to Phillip Unwin Managing Director,RUAG Ammotec UK Ltd.E-mail: phil@ruag.co.uk , and he sent me a new cable and a better quality plug attached,so those of you with problems get in touch . anyway i took my lamp to a mate who is more patient than me and he rewired it for me but while testing found that the variable control was faulty as well , so i got my lamp but no variable control now , s
