The gradual conversion to LED lighting \u2013 which has a more cool blue appearance \u2013 reduced that overall haze of yellow to a large degree and kept the lighting more tightly focused onto the areas it was meant to illuminate due to the directional nature of LEDs.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-1024x583.png\" alt=\"\" class=\"wp-image-1715 lazyload\" data-sizes=\"auto\" data-srcset=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-1024x583.png 1024w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-300x171.png 300w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-768x437.png 768w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-1536x875.png 1536w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-450x256.png 450w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-20x11.png 20w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-225x128.png 225w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-900x513.png 900w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580-1350x769.png 1350w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-criteria_1580.png 1580w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>The result is that the commercial sector has been able to get light pollution more under control. \u201cThere\u2019s still a long way to go, but residential [use] has turned out to be more of an addition to sky glow than we had previously thought and now the focus is on residential outdoor lighting and the [circadian] disruptions it can cause,\u201d he stated. &nbsp;\u201cWe [DarkSky Association] have found that a lot depends on the type of lighting used, as well as the type of light source, and so there are going to be some changes.\u201d<\/p>\n\n\n\n<p>McGowan shared an image of Chicago\u2019s downtown in the era of high-pressure sodium lighting, followed by a recent image where LED illumination in the same area has dramatically cut down on sky glow.<\/p>\n\n\n\n<p>There is still room for improvement, however. \u201cWhile LEDs have been good overall for shielding light pollution, the blue wavelengths from LEDs are still a problem,\u201d McGowan stated. \u201cThe point is that it is not just street lighting anymore that contributes to the sky; residential lighting has gained importance. The world has become brighter \u2014 whether it comes from &nbsp;a streetlight or from somebody\u2019s window. We are losing our darkness, and when we lose our darkness, we lose a lot of things,\u201d he remarked. \u201cVisible light pollution has turned out to be an environmental concern, as it affects all living things \u2014 from animals to birds to insects. As the general public has become more aware, we have many more organizations and people who are saying, \u2018It\u2019s time to do something.\u2019\u201d In response, DarkSky International put out a simple consumer guideline a few years ago that provided the basic tenets of what homeowners need to look for when buying and installing outdoor lighting.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-1024x583.png\" alt=\"\" class=\"wp-image-1716 lazyload\" data-sizes=\"auto\" data-srcset=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-1024x583.png 1024w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-300x171.png 300w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-768x437.png 768w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-1536x875.png 1536w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-450x256.png 450w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-20x11.png 20w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-225x128.png 225w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-900x513.png 900w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580-1350x769.png 1350w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-solutions_1580.png 1580w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>According to McGowan, this topic should become more important to lighting showrooms and manufacturers since a 2023 study has indicated that residential lighting is contributing more to light pollution year over year. There is another key point to keep in mind: It isn\u2019t just the outdoor lighting on homes that is contributing to the problem, but also the light emanating from inside the home via floor-to-ceiling windows and skylights that spill out past the home\u2019s exterior. \u201cLight emitted from windows makes up a significant part of sky glow, so perhaps that is a business opportunity for showrooms that sell motorized shades and window coverings that can limit the [light spill] to some degree,\u201d he commented.<\/p>\n\n\n\n<p>McGowan explained that offering DarkSky-compliant outdoor fixtures does not mean the consumer will have less light for pedestrian safety on walkways or on porch stairs. \u201cIt involves shielding the light source in some way that minimizes light trespass into nearby homes, directs the light to where it\u2019s neededt, and reduces glare, which is a problem with LEDs more&nbsp; than with any other light source the industry has ever used,\u201d he said.<\/p>\n\n\n\n<p>Common rules of thumb for DarkSky\u2019s newest guidance for compliance includes:<\/p>\n\n\n\n<p>\u2022 &nbsp;Shielding, plus the ability to dim or change the intensity or the timing of the lights can make a big difference, according to McGowan.<\/p>\n\n\n\n<p>\u2022 Light output is limited to 1,000 lumens. \u201cThis covers most of the outdoor lighting that we tend to use for lighting, whether at the door, the porch ceiling, or other common places. Uplight in the 90- to 80-degree range will be limited. \u201cIt\u2019s realistic to have some spill light,\u201d McGowan said, adding, \u201cThere is a clause in the DarkSky recommendation to be able to do that.\u201d<\/p>\n\n\n\n<p>\u2022 Color temperature should be 3000K or less. \u201cYou can vary it if you feel that it should be warmer, or a bit cooler, over part of the evening. Just don\u2019t go over 3000K. &nbsp;You do need a standard photometric to be officially DarkSky-compliant,\u201d McGowan stated.<\/p>\n\n\n\n<p>\u201cThis topic is going to become more important, and it could become more of a marketing opportunity for ALA and ALA-member manufacturers and showrooms,\u201d he said. \u201cThis is not strictly a U.S. certification, it applies all over the world. DarkSky has 70 chapters worldwide in 30 countries and about 993,000 supporters and members and advocates who work with us from a variety of organizations in order to move this whole idea along.\u201d<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"583\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" data-src=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-1024x583.png\" alt=\"\" class=\"wp-image-1717 lazyload\" data-sizes=\"auto\" data-srcset=\"https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-1024x583.png 1024w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-300x171.png 300w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-768x437.png 768w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-1536x875.png 1536w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-450x256.png 450w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-20x11.png 20w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-225x128.png 225w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-900x513.png 900w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580-1350x769.png 1350w, https:\/\/lightingnewsnow.com\/wp-content\/uploads\/2025\/08\/DarkSky-shielding_1580.png 1580w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>McGowan concluded his presentation to the Engineering Committee by stating, \u201cWhat we have here is an opportunity for ALA members \u2014 especially from a fixture standpoint as a way to reduce the amount of light that causes sky glow and from the standpoint of caring about the environmental effects that stray light causes.\u201d &nbsp;<\/p>\n\n\n\n<p><em>Lighting News Now<\/em> asked whether there is a national dark sky-friendly standard for all municipalities to follow or if it will remain up to the discretion of each city and state to decide \u2014 an aspect that has been a stumbling block for achieving nationwide adoption. McGowan answered that the goal is to get the DarkSky language to the point where it can be used and adopted by various cities and other organizations that decide local ordinances.<\/p>\n\n\n\n<p>\u201cI think this will still be a local [decision], but we wish that more cities will find the DarkSky [guidelines] easy to adopt,\u201d McGowan said. \u201cFor example, DarkSky spent time recently working up the [lighting] language for seaports. The ports organization came to [DarkSky] and said they\u2019d like to have dark sky lighting for ports, which have a lot of stray light, of course, because the lights are on at all hours of the day and night. The ports&nbsp; organization adopted DarkSky\u2019s verbiage and suggestions and passed official DarkSky certification. \u201cI think we have a chance to create language that is understandable by municipalities to adopt going forward. I think it will be better [than what is in place currently], but it won\u2019t be perfect.\u201d<\/p>\n\n\n\n<p>At Lightovation in January and June, more manufacturers were displaying what they label \u201cdark sky-friendly\u201d fixtures that meet most of the criteria set by the DarkSky Association, but without the official designation (said to be a cost-saving measure). Look for this category to grow on the manufacturer level as well as among consumers as awareness gathers momentum.&nbsp;<\/p>\n\n\n\n<p><strong>Related articles<\/strong><\/p>\n\n\n\n<p><a href=\"https:\/\/lightingnewsnow.com\/?p=873\">Terry McGowan Retires from ALA, Mary Beth Gotti Takes Over the Role<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/lightingnewsnow.com\/?p=1578\">Make Your Voice Heard in Shaping Dark Sky Requirements &amp; More<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Terry McGowan, FIES, LC, retired director of Engineering at the American Lighting Association (ALA) and co-chair of the Technical Committee of the DarkSky Association, presented the latest findings from the DarkSky Association to the ALA Engineering Committee last week. \u201cWhen it comes to residential lighting and dark skies, there is some new information that I&hellip;<\/p>\n","protected":false},"author":2,"featured_media":1718,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"iawp_total_views":118,"footnotes":""},"categories":[11],"tags":[53,481,535,537],"class_list":["post-1713","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-business","tag-ala","tag-dark-sky","tag-darksky-association","tag-engineering-committee"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
