Much of the glare is believed to come from light that is emitted from lighting fixtures, often referred to as “spill light”. In many cases, the lighting fixtures emit light at almost all angles, and little can be done with the design due to the requirements of the task, such as baseball or football field illumination. Municipalities have begun to respond to criticism of exterior lighting with increased “lighting regulation” rules, that mandate certain lighting requirements for luminaires. “Full-cutoff luminaires” have been identified in these regulations as “good lighting”, and so Kurtzon joins other manufacturers who are putting effort into developing a product line to meet this demand. 2 5 0 10 1 2 Due to its emphasis on “wet-location”, “vandal-resistance”, and stainless steel construction, Kurtzon has had a longterm product in its catalog with some of the requirements of a “Full-cutoff “ luminaire: the 836 series in the “Environmental” section. Kurtzon has recently decided to upgrade its design effort to present a new catalog sheet. 3 Kurtzon’s Wet Lock 836 Series Luminaire We have retained the original quality features, improved others, and are now providing more application data for this product series. 0 1 2 3 4 Distance in units of mounting height. Values based on 10 foot mounting ht. Distribution on the Vertical Surface. Shown below is the main vertical luminance pattern. In addition to offering an exterior wall-mount product, UL listed for Wet Location, designed for full angle cutoff below 90 degrees, and with a low profile as before, we have made some improvements in the current design. The fixture is now designed with a “drop” frame held by stainless aircraft cable, and is provided with mounting KO’s for either wall or surface mounting, along with surface conduit capacity for both mounting configurations, as standard. Our reflector is a “low iridisence” type. Project: Fixture Type: Catalog Number: Application: (2) 100w HPS luminaires at 10Ft. mounting ht. on 20 ft. centers Approved by:
