Does anyone have the proper solution for the case study of "lighting the way at the manor house hotel" by Harvard business review? I have this assignment which we are supposed to read the case, (4-5 pages) then write our solution on which type bulb should the hotel use from costing perspective. I am not sure if I can share copy of the case due to copyrights of HBR. Does anyone by any chance passed by this case and have the proper solution?
