Goldendale Does it Right.
We have been critical of the City of Goldendale, Washington – and justifiably so – for its failure to promote or enforce its own lighting code (along with Klickitat County), and failures in fulfilling the promises made decades ago to protect and conserve the night sky of the Goldendale Observatory. But we would be remiss if we did not recognize the City for getting it right with the new Klickitat County Services Building across from the Klickitat County Courthouse.
As can be seen in the photo, full cut-off street lights prevent light spilling above the horizontal and efficiently direct light downward to where it is needed. Additional decorative wall lighting on the building is also fully shielded. Both use what appears to be 3000K LED "warm" lighting elements putting out less blue light than typical LED streetlights, which is an important feature in reducing artificial sky glow, as well as being healthier for the public.
So a job well done demonstrating good nighttime lighting can be efficient, attractive, and help conserve the night sky.
