yeah i did heard about that and not only mcgill compaine but few other compaine too have the same probem too and i use insluated cord something like oversized so or soj cables with molded light socket that i used for small area BUT for large area i used the hid light fixure with wirecage on it ( manufactered by rudd compaine) and work out very nice for large area
btw check the catalog on mcgill to find diffrent version with molded socket with plastic cylinder attached that what i used
merci marc
