Appendix A shows a spreadsheet of cost and energy use data that was input for the benchmark T8 fluorescent option, compared to a linear LED alternative estimated at 15 minutes labor. Similarly, Appendix B shows the same type of data, but for a linear LED alternative estimated at 30 minutes of installation labor. Not all permutations of labor hours, annual operating hours, linear LED lamp cost, and melded electric rates are shown in Appendices A and B, but all were included in the BLCC calculations.
