Typical new installations of es8™ lighting save $12 per fixture per year in electricity costs, $3 in re-lamping costs, and provide a simple payback in less than 30 months on new construction. Over a 15-year life-cycle this amounts to an estimated reduction in cost of ownership of $225 per fixture in energy, lamps and maintenance costs. Relight versions can save nearly three times these amounts when replacing 4 lamp T12 fixtures.
