Existing light fixtures burn approx. 415 watts each including bulbs and ballasts. Existing light quality has a low color rendering index. Lights take several minutes to come on. Note: These retrofits will be completed during the summer of 2009. Near the end of March ’09, communications with LKSD revealed the school district was committed, had the budget and had a solid electrical contractor who could complete this job - in kind to the grant. Previously this measure was not viable as no labor resources were available on the part of LKSD to complete the upgrade. LKSD has provided a letter to ABSN guaranteeing completion of this measure in summer '09. Savings, light quality and light level improvement will be excellent.
