As a side job, I do lighting for a local church. Their space is very old, and uses 3 rows of Major strip lights for main stage lighting, in addition to several flavors of pars, fresnels, and ancient elipsodials. The striplights take 100w long neck incandecant bulbs. As the availability of these is going to be questionable in the future, are there any other options for lamping? The lights are powered from an old autotransformer board, so issues with SCR dimmers are not present here. Does this open up other lamp options? Would it make more sense to procure more modern striplights that take halogen bulbs? There is limited budget, so we are looking to keep running as cheaply as possible for as long as possible. Any advice would be appreciated.
