Dark sky friendly luminaries with good cut-off characteristics produce less light pollution and distribute a greater portion of their output into usable lighting zones. This is not only more efficient, it produces a more conscientious overal lighting design by redirecting wasted uplight back down to the ground. Horizontal reflectors in Type III and V distribution are also available to fit inside of any one of our designes giving you full cut off with controlled distribution. These optional features integrate smoothly into our entire line of cast aluminum poles, cast iron poles and our municipal grade tapered steel poles.
