175w Metal Halide fixtures were rewired, bypassing the ballast, installing magnet/centre light converters and using these lamps. If you look at this setup next to 175W lights you won't see any difference in light output or quality of light, but you get a savings of 130W per light. So I'm gradually upgrading the exterior lighting of the entire church complex and tracking lamp life and savings on energy bills.
