Idaho Power recently made a filing with the Idaho Public Utilities Commission requesting approval to change all area lights, flood lights and company-owned street lights from high-pressure sodium lights to LEDs. If approved, Idaho Power anticipates starting the changeout in fall 2019.
LED lights provide significant advantages over the existing high-pressure sodium lights. LED lights provide better lighting quality, consume less energy and require less maintenance.
Due to changing technology within the lighting industry, Idaho Power has less certainty regarding the future availability of the existing high-pressure sodium technology.
No. If approved as filed, Idaho Power will no longer maintain an inventory of high-pressure sodium lights as the transition is made to LED street lights. Idaho Power will replace all company-owned street light fixtures with LED fixtures.
The only exception to the 3,000K expected is the Schedule 15 flood lights, which are specified at 4,000K. Schedule 15 flood lights are specified at 4,000K because many of the existing flood light fixtures utilize metal halide lamps operating at approximately 4,000K. This type of lighting is not dark-sky compliant due to the nature of a flood light fixture in general.
