Because of being lit 24 hours, 7 days a week, and are required by law for commercial buildings, the output signals are one of the first areas that a company consider for a lighting retrofit. The flags output using light emitting diodes (LEDs, the acronym in English) can save up to 90% in energy costs. The output signals old need frequent maintenance because the bulbs burn with greater frequency in relation to the LEDs. Some old lamps need to be replaced four times a year, according to an article BigNews. The return on investment in exchange for light emitting diodes is around nine months.
Another study found that out the old flags can consume over 350 kilowatt-hours and cost $ 28 each for annual operation, while the LEDs, the stamp Energy Star, consumes only 44 kWh of electricity and cost less than $ 4 annually to operate, according to a study by SolutionsforRemodeling.com. As an example of a recent retrofit, the Misericordia University is using the stimulus of federal funds to replace 42 flags output incandescent installations LEDs, according to the Times Leader. The retrofit of the output signals is part of a lighting retrofit larger university, which received more than 170 thousand dollars in incentive funds for the project.
