A year of so ago I relamped my 1000 watt metal halide high bay fixtures with 950 watt metal halide lamps to save energy. Since the installation I have been experiencing catastrophic failure of the sockets. When the socket/lamp fails it melts both the socket and lamp base to the point of being unrecognizable. After discussions and research by the lamp manufacturer they are pointing to the socket as the weak link. They claim that there is an issue with using stainless steel in the sockets and produced a NEMA document to support this. Anyone ever heard of this socket issue or experienced anything similar with 950 watt metal halide lamps?

I have never used any 950 watt lamps, are these lamps rated to use the same ballast as the original 1000 watt lamps your replacing? are they pulse start lamps and your using a standard ballast?

Were these old fixtures that hadn't had problems before? Are there any that still have the old lamps in the fixture? If there are, have they failed?
