If you work with lighting, you have probably seen the specification UGR <19<\/strong>.<\/p>\n\n\n\n But what does it actually mean?<\/p>\n\n\n\n UGR stands for Unified Glare Rating<\/strong> and is used to evaluate discomfort glare from lighting.<\/p>\n\n\n\n In simple terms:<\/p>\n\n\n\n Lower UGR means lower potential discomfort glare.<\/strong><\/p>\n<\/blockquote>\n\n\n\n So, UGR <19 indicates a low level of potential discomfort glare under the relevant lighting conditions.<\/p>\n\n\n\n It does not mean that there is no glare. It means that the lighting is designed to provide good glare control.<\/p>\n\n\n\n Glare becomes more important when people need to concentrate or perform visual tasks for long periods.<\/p>\n\n\n\n For example:<\/p>\n\n\n\n In these environments, lighting needs to provide not only enough illumination, but also comfortable visual conditions.<\/p>\n\n\n\n Not necessarily.<\/p>\n\n\n\n UGR is only one part of lighting quality.<\/p>\n\n\n\n A good lighting solution also needs to consider illuminance, light distribution, beam angle, color quality, efficiency, and the function of the space<\/strong>.<\/p>\n\n\n\n Different spaces have different requirements. A retail store, restaurant, office, and home do not necessarily need the same level of glare control.<\/p>\n\n\n\n The goal is not simply to achieve the lowest possible UGR.<\/p>\n\n\n\n It is to achieve appropriate glare control for the space and its users<\/strong>.<\/p>\n\n\n\n For a lighting designer, UGR <19 is a technical specification.<\/p>\n\n\n\n For the user, it means something simpler:<\/p>\n\n\n\n More comfortable light for prolonged visual tasks.<\/strong><\/p>\n\n\n\n That is the real value behind the number.<\/p>\n\n\n\n At KOE, we believe lighting quality is not only about how much light we produce, but also how comfortably people experience that light<\/strong>.In the next article, we will look at how UGR is calculated<\/strong> and why the same luminaire can produce different UGR results in different lighting environments.<\/p>","protected":false},"excerpt":{"rendered":" If you work with lighting, you have probably seen the specification UGR <19.
