Just tried to fit some IP65 fire rated spots in a clients bathroom, picked them up from C(sh)ity Electrical, absolute pooh, cut the holes in ceiling (73mm) tried to fit the first but the springs wouldn't hold the spot in place, tried the next and was just the same. 4 holes in ceiling and no lights not good so when I order up the next lot when this load of landfill goes back, which ones should I order as this is the last time I let City order me in that junk. Any suggestions?
