Default Fixture Wattage Reference Table

This table is to be used as a reference for determining the wattage of baseline (existing) fixtures for the ComEd Energy Efficiency Program. Wattages for all new (proposed) fixtures should be referenced from the new product specifications.

There are many factors that affect the input wattage of a fixture: ballast factor, lamp quality, system voltage, etc. The more information that is provided about your project, the more accurate the incentive and energy savings calculations can be. If there is any doubt as to which fixture type is correct, the conservative wattage will be used. To ensure that the wattages used in incentive calculations are as accurate as possible, pictures are recommended for all of the fixture types listed below in red marked *.

This table is made up of the most common fixtures but does not include all fixture types. T12 fixtures are listed with energy-saving (ES) magnetic ballasts and standard magnetic ballasts. If a fixture type is not listed on this table, it does not necessarily mean that the fixture is not eligible for an incentive. Please visit ComEd.com/BizIncentives or call us at 855-433-2700 if you have any questions.
