(Leah Hogsten | Tribune file photo) A photo taken of 100 North in Torrey, Oct. 18, 2017 shows the light output and color of three newly installed LED lights in comparison to the two remaining sodium vapor lights. Garkane Energy Cooperative replaced the remaining sodium vapor lights on 100 North with new lights, using spectra at 3000 Kelvin or less, that direct light away from the sky.
