This roadway luminaire has two features that enable it to meet ASA standards for acceptable brightness at greater than conventional pole spacing-to-mounting-height ratios. The first feature is the vertically positioned lamp, which maximizes utilization of the lamp's light emission. The second is the prismatic refractor, which spreads light evenly in a wide distribution and also directs lateral light emission downward to add to useful output.
A hinged refractor door with tool-less entry allows for simplified maintenance and relamping. For pendant-mounted versions, an optional integral Plumbizer ensures that the luminaire installs plumb.
SRL is designed to utilize a wide range of light sources, including High Intensity Discharge (HID) and others. These light source families provide high efficiency in lumen output, service life and energy use.
