A light fixture for a security lighting system includes an elongated pipe having a lower pipe section, an upper pipe section, and an articulating joint coupling a lower end of the upper pipe section with an upper end of the lower pipe section for enabling the upper and lower pipe sections to articulate relative to one another. A clamping element is coupled with the lower end of the lower pipe section. A glare shroud is secured to the upper end of the upper pipe section. One or more LEDs are secured to an underside of the glare shroud. Each LED has an optical lens that is configured to pass light from the underside of the glare shroud at a predetermined beam angle of 137-156 degrees.
