MR Credit: Purchasing - Lamp

  • Use the mean lumens value in the calculations. Refer to the Further Explanation, Reading Lamp Cutsheets section of this credit in the LEED O+M v4 Reference Guide for more information.
  • Ensure that all mercury-free lamp types included are at least as energy efficient (lumens/W) as their mercury-containing alternatives.
  • In the case when manufacturer documentation does not identify the mean lumens (as seen on manufacturer documentation for CFL lamps), subtract 20% from the initial lumen value.
