Many communites have installed cut off light fixtures which point light down to the ground as opposed to the drop-lens cobra luminaire which allow light to spill out the sides and even upward, where light is not needed. Communities have found a financial gain to using cut off light fixtures as it cost less to illuminate areas that ONLY need to be illuminated. Much of the light that our towns and cities use on roads is wasted energy and money.
Right now I am information gathering I'd like to know if anyone has been part of the movement in changing their towns light fixtures and how the process went for you. I have links to IDA and have stated reading the brochures within the page. Please feel free to reply with your experiences.
