How can these LED lights replace higher lumen devices?
Controlled directional emission and elimination of the “hot spot” Bulb type light fixtures may be about 60% efficient in getting all that light to the target, meaning that 40% of their light is bouncing around trying to get out of the fixture when the bulb itself is blocking the opening. IntenCity is more than 80% efficient getting its light to the target. The 75 Watt LED streetlight is able to provide 3-times more footcandles on the ground per Lumen generated than conventional bulb fixtures. That “hot spot” produced by HID lighting is eliminated with the IntenCity Luminaire, in part for Dark Skies compliance, but mostly because it is an unnecessary waste of energy. Typically 1/3 of the HID light production is focused downward and creates 4 to 5 times higher brightness there, rather than spreading that energy outward. In addition, some communities use a multiplier due to customized color temperature. In that regard, when luminance is about 1 cd/M2 (near scotopic) IntenCity provides sim
