Hi guys, did an installation back in May which included a couple of 500W halogens overlooking a car park. One bulb blew after about 3 months and now both have blown again a couple of times. I tested the circuit when the first bulb blew quickly and all appeared ok, so just thought it was a duff bulb. Its now got me thinking there is more to it than that. Surely these should last longer than a month or two? Any idea's? There is only the 2 halogens on the circuit, wired in 1.5 T+E with a 6A mcb on a brand new TNCS supply, although it is rural fed from an overhead pylon and I was getting 257 volts at the meter. I'm going out to test it again this week but would appreciate some feedback if anyone out there has had a similar problem.
