You are watching: Will metal halide work mercury vapor


I did 2 jobs recently, and both involved changing out mercury vapor to metal halide.My boss told me that MH works just fine with mercury vapor ballasts, and it"s true. However, I did notice that all the outdoor changeovers, the MH bulb cooked off the vapor ballasts, whereas the indoor ones seem to be working just fine.Anyone else have xp on this?It"s a crying shame the companies I sometimes work for have a tiny budget.
Don"t know why there would be a difference in the outside and inside fixtures. We usually change out the ballasts when we change over, the customer is paying for it. But I"ve made mh lamps work on a mv ballast but I"ve always disconnected the igniter

Most of those ballast are combination MH,MV as long as you get the correct ANSI lamp they will work like they are supposed to,No need to diconnect the Igniter unless is says so on the ballast.

Almost none of the Mercury vapour ballast I have ran into do not have igniters or starters on them due they are probe start by design and now with other thing with Metal Halide probe start it can use the MV ballast as long it can meet the ANSI specs.However there is one quirks I have allready know it for long time is during the very cool or cold weather they will not start the MH bulbs with MV ballast due the open circuit voltage is not high engough to overcome it I have see it before quite few time.Really if you really want to get the best performace on MH bulbs you may have to switch over to Pulse start Metal Halide bulbs with PSMH ballast then it will match with each other and nice thing with PSMH"s they can start better in cold weather than probe starters and they are brighter as well.Merci,Marc
