Hi Everyone, I work at a HS and our Stage lighting is not exactly "New" We have three LARGE light bars above our stage that have red white (clear) and blue glass lenses. Over the years a decent amount of those lenses have disappeared. I don't even know the correct name of the light bars let alone those lenses.... Can you educate me on the names I am missing and perhaps where (if) I can get replacements? I have attached a picture of one of the lenses I removed. They say Major Chicago Illinois Also they seem to have 150 watt Sylvania bulbs in them - I need to replace around 90 of them. Any particular recommends of type and maybe cheap places to get them? Thanks in advance and Happy Thanksgiving!
