The first cost of an LED Street Light conversion will require a significant capital outlay. LED Lights are considerably (2-4 times) more expensive than conventional HID “cobra-head” style lights. Because of the lack of standardized wattages and the complexities of getting new rates approved, most regulated Investor Owned Utilities (IOU’s) today don’t offer LED street light tariffs for unmetered street lights. Therefore, even if a city converts all of the street lights to LEDs and reduces the power consumption by 50% or greater, most IOUs will only reduce the street lighting bill slightly or not at all. However most IOU’s are aware of the benefits provided by LED technology in street lighting and many are working to develop these tariffs.
