Information Sheet

Lighting Efficiency input wattage guide Please use these wattages when calculating estimated wattage savings for Lighting Efficiency rebates. These estimates figure electricity drawn by the system in an enclosed fixture and are taken from existing test data or calculated for similar lamp/ballast combinations. • This wattage guide is provided to estimate energy savings. Energy savings calculations are estimates and may vary from actual results. • Fixture wattages may vary slightly between different model numbers and manufacturers. The type of fixture and method of installation will affect the actual system wattage. • Lighting projects evaluated under the Custom Efficiency program may use the information contained in the Input Wattage Guide as a starting point; however, current policies or program rules that are in effect can cause adjustment to any of these values.
