As it happens, the stars have aligned between curiousKC and the historic astronomical event coming Aug. 21.

Just as our region was preparing for the full lunar eclipse, Kansas Citian Clark Johnson wondered if there is any local regulation of light pollution. Johnson asked curiousKC: Is there an ordinance for reducing light pollution?

While light pollution can come from many sources, some natural, most are human-made. Kansas City, like most built-up cities, has a sky glow, city light reflected in the night sky. The glow from our artificial light blocks from view around 46 billion light years or the approximate size of the universe.

What we found is that Kansas City does regulate outdoor lighting that can bother neighbors. Or, as the city code puts it, the intent is to protect the public health and general welfare by controlling the adverse impacts of glare and light trespass associated with poorly shielded or inappropriately directed lighting fixtures.

The code calls for partial shielding of light in some cases, and states unequivocally that glare must be avoided by reflecting outdoor lighting away from residences and streets.

Exemptions include temporary holiday light displays.

The strongest wording from Kansas Citys zoning and development codes on outdoor lighting says, All outdoor light sources that produce more than 4,050 lumens must be at least partially shielded.

However, that amount of lumens isnt much of a restriction. The average halogen car headlights are around 800 lumens at low beam and around 1300 lumens at high beam.

Most unshielded lights waste energy and contribute to light pollution. Dark-sky advocates, those who work to reduce light pollution, would argue an example of unnecessary light escaping upward can be found in the Riverfront Heritage Trail in Berkley Park near the River Market. The trail stretches 15 miles long, and is lit by old fashioned-styled lamps that have no top shield.

Seeing stars that arent dimmed by downtowns lights doesnt happen until you are more than 30 miles from the city center, and even then, you havent gone far enough to see them all. It takes double that distance to reach an area considered a dark night sky. We used this map to find a close dark spot to Kansas City.

As for the eclipse, Carolyn Adkins, City Streetlight Maintenance Supervisor, said Kansas Citys automatic lights are on photosensors, much like automatic headlights on a car, and would most likely be activated during the dark parts of the celestial event. She noted this would keep the streets safe for pedestrians and drivers.

Women who live in areas with higher levels of outdoor light at night may be at higher risk for breast cancer than those living in areas with lower levels, according to a large long-term study from Harvard T.H. Chan School of Public Health. The link was stronger among women who worked night shifts.

The study will be published online August 17, 2017 in Environmental Health Perspectives.

"In our modern industrialized society, artificial lighting is nearly ubiquitous. Our results suggest that this widespread exposure to outdoor lights during nighttime hours could represent a novel risk factor for breast cancer," said lead author Peter James, assistant professor at Harvard Medical School's Department of Population Medicine at Harvard Pilgrim Health Care Institute, who did the work while a research fellow in the Departments of Epidemiology and Environmental Health at Harvard Chan School.

Previous studies have suggested that exposure to light at night may lead to decreased levels of the hormone melatonin, which can disrupt circadian rhythmsour internal "clocks" that govern sleepiness and alertnessand, in turn, lead to increased breast cancer risk.

The new study, the most comprehensive to date to examine possible links between outdoor light at night and breast cancer, looked at data from nearly 110,000 women enrolled in the Nurses' Health Study II from 1989-2013. The researchers linked data from satellite images of Earth taken at nighttime to residential addresses for each study participant, and also considered the influence of night shift work. The study also factored in detailed information on a variety of health and socioeconomic factors among participants.

Women exposed to the highest levels of outdoor light at nightthose in the top fifthhad an estimated 14% increased risk of breast cancer during the study period, as compared with women in the bottom fifth of exposure, the researchers found. As levels of outdoor light at night increased, so did breast cancer rates.

The association between outdoor light at night and breast cancer was found only among women who were premenopausal and those who were current or past smokers. In addition, the link was stronger among women who worked night shifts, suggesting that exposure to light at night and night shift work contribute jointly to breast cancer risk, possibly through mechanisms involving circadian disruption. The authors acknowledged that further work is required to confirm the study findings and clarify potential mechanisms.

The first solar eclipse Fred Espenak saw was electrifying. It was March 7, 1970, and Espenak, who had just earned his drivers license, drove his familys car from Staten Island down to North Carolina. "I thought I was really prepared for the eclipse. And then the moon shadow swept over us, and we were plunged into totality," he said, referring the zone of complete darkness that occurs when the moon passes between the earth and the sun and fully blocks the star. "I promised myself that this could not possibly be a once-in-a-lifetime experience because it was just so beautiful, so spectacular."

Decades later, Espenak, 64, a retired NASA astrophysicist, enjoys the nickname "Mr. Eclipse," for his research on eclipse predictions and eclipse photography. A well-known figure in the universe of eclipse chasers, hes traveled all over the world to see 27 total solar eclipses no easy feat given that a total solar eclipse graces any given place in the world just once every 375 years.

Espenak's most memorable eclipse took place in India in 1995. It was a long trip there to see a short, 41-second eclipse. He was traveling with a tour group, and one woman happened to catch his eye. "I just said, 'Hmmm.' Nice hair," Espenak said. The 1995 eclipse was Patricia Totten's first, though she had been trying for more than 20 years to see one.

In the years that followed, a shared interest in eclipses and science (Totten is a former chemistry teacher) helped them stay in touch. Years later, the two began dating, and they got married in 2006.

Fred and Patricia Espenak, both retired, now live in Arizona Sky Village, an eastern Arizona village designed for astronomers who want to make observations with minimal light pollution.

"I've always wanted to live someplace where I could go out and really see the Milky Way any night," Fred Espenak said. But to get away from the light pollution that plagues so much of the U.S., the Espenaks have "abandoned civilization, so to speak," he said. The nearest grocery store is 60 miles away. Their backyard is a great expanse of desert, and the couple has seen rattlesnakes, bobcats, and coyotes pass near their home. The village even has rules around outdoor lighting at night: namely, there can't be any. There are no streetlights, headlights must be curbed, and the Espenaks' home is even outfitted with blackout curtains. All this means that if Espenak wakes up at 1 or 2 a.m. to go stargazing in the two observatories he built, he's often able to see the Milky Way and galaxies far, far away.

"I think it's wonderful to be married to somebody with a passion," said Patricia Espenak, 73. The two have turned their love for eclipses into a full-time hobby. They travel the world together, from China to Antarctica, chasing the celestial phenomena. "All my world travels, with solar eclipses, [have] given me a greater appreciation for different cultures," Fred Espenak said. "A greater acceptance to appreciate the diversity of the people on this planet."

Lighting manufacturer aspectLED has announced it has created a new landscape LED lighting category in response to demand.

Based off the companys Modern Series landscape lights, the Black Series landscape lights are offered at a lower wattage and cost. Developed in order to respond to the demand for an outdoor landscape and in-ground LED lighting category, the Black Series boasts a 50,000-hour life span, requiring no maintenance for decades.

The landscape lights have a safe low voltage of 24VDC for easier wiring, and according to the company can use up to 80 percent less power than equivalent incandescent fixtures. Constructed to withstand high shock, vibration and moisture ingress, the lights are available in multiple single colors or a color changing option.

Listening to our customers has always been critical to our business, said Mike Crissinger, director of marketing for aspectLED. When looking at our outdoor lines, between in-ground/well lights, stake/surface mount landscape lights and underwater pool lighting, mid-range 6 to 18 watt models seem to be customer favorites. It only makes sense to expand our offering in that segment.

aspectLED has a wide selection of outdoor lighting including in-ground well fixtures, pathway/driveway lights, underwater recessed, tripod, fountain and stake and surface mount landscape lights. For more information on their lighting lines, click here.

Expanding its selection of landscape lighting, WAC Lighting is now offering LED path lights, which are available in Ledge and Balance styles.

Balance LED Path LightPhoto: WAC Lights

These lights are designed to outline existing exterior features such as paths, driveways and ponds creating soft, even illumination. The fixtures are slim and linear. The Balance style is tall, slender and provides a wide spread of illumination. The Ledge style is shorter, wider and provides more direct lighting. The angular, nondescript design allows it to blend into the surrounding landscape.

Both fixtures are built from corrosion-resistant aluminum. They are IP66 rated and factory sealed to resist any water penetration, including high-pressure water jets. The LED path light fixtures come in either black or bronze features.

The customer can choose between warm white with a color temperature of 2,700K and pure white with a color temperature of 3,000K. The light has a constant output for 9V-15V input.

VOLT Lighting has introduced over 200 new products in the past two years, and one them was the Pro Junction Hub, and now the company has an upgraded version.As a hub-type connector, the Pro Junction Hub allows the installer to connect up to seven fixtures and the main line from the transformer. By using a hub, the installer can ensure the lights all receive similar voltage and they provide a voltage testing point before and after installation.

VOLT was the first company to use clamp-type connectors in hub junctions, said Michael Caselnova, Jr., director of product development and marketing for VOLT. Clamps are much easier and faster than typical twist-type hubs or hubs that use set screws.

The introduction of the Pro Junction Hub was welcomed by lighting professionals, and VOLT Lighting encouraged reviews and feedback from the customers. The response for the clamp was positive but they wanted them to be more accessible in the hub and easier to open and close.

Within a few weeks of introducing the first Pro Junction Hub, we were in our Innovation Lab re-designing the hub and testing new prototypes, Caselnova said. A few months later we went into production and launched the improved Pro Junction Hub. A new, upgraded clamp is used that is much easier to open and close, and the clamps are attached to the underside of the hub cap more accessible and secure.

For example, having purposeful but decorative lighting by your front door helps you gain entry at night, and it also allows guests and visitors to see the front of your home. Much more aesthetically pleasing than a standard floodlight, consider hanging pendants that are easily installed into the roof of your front porch or stoop.

When lighting up the outdoors, first consider your purpose. Outdoor dining areas have different lighting needs than areas for lounging and conversation. The right outdoor lighting helps you better enjoy and use your outdoor space, whatever its purpose.

Outdoor dining

Having an outdoor kitchen in summertime is optimal. Even a simple gas grill can go a long way in conserving the coolness of your home. No matter the scale of your outdoor cooking area, it needs task lighting. Recessed fixtures can be hidden in the beams of an overhead patio cover or pergola, or outdoor sconces can be mounted above the cooking surface for added safety and accuracy with food preparation.

Dining surfaces require less task lighting than cooking surfaces. Therefore, this light can be functional as well as decorative. For example, twinkling starlight pendants not only provide enough light to eat, but the glittery light they spray out of tiny holes adds a romantic feel to the dining experience. Or, hang string lights over your outdoor table like the roof of a tent this will not only provide enough light to eat by, but also adds ambiance.

Theres never been a better chance that your get-together, and the food you present, will end up photographed and posted on the web. If you want those pictures to look great, lighting can help. Warmer colored light, that is light high in oranges, yellows and reds, makes food and people look natural. Cooler light, or blue-colored light, although great over outdoor kitchens for task lighting, can make people and food appear washed out.

Outdoor R and R

Like indoor lighting, exterior decks and patios are best lit in layers. For most of your exterior lighting, hiding the light source is best as it reduces glare and helps create a relaxed mood. Placing fixtures in landscaping, or overhead in trees or soffits will help conceal fixtures, cords, and wires. Post lights are concealed and decorative, and can even be made to cast patterns on the surface of your deck or patio turning light to art.

A range of assorted products are available to meet all your outdoor needs. Rope lighting can be placed under railings, or along the edge of a wooden walkway or concrete path. Super flat rope lighting is so thin its practically invisible. Undercap lighting, a type of strip light, can be placed under the edge of a sitting wall or bench, or as stairway lighting when applied under the cap of each step.

Installing hidden fixtures high over your outdoor area, or moonlighting," will mimic soft, romantic moonlight even when the moon is nowhere in sight. Be sure to use LED lighting with anything high it will reduce the number of times you need to climb a ladder, or hire someone with a lift, to replace bulbs.

Outdoor ceiling fans help maximize your R and R when the evening is a warm one. Before purchasing your outdoor fan, pay attention to its rating by Underwriters Laboratories. An outdoor fan thats UL rated damp means the fan is well suited for moist locations where it wont be directly exposed to water. A UL rating of wet means the fan will withstand direct exposure to water snow, rain, ice, or even water squirted from a hose to clean it.

For those without clear purpose

The answer to all of those without clear purpose is dimmers. Dimmers allow you to multipurpose, and offer forgiveness for changing your purpose. Dimmers can not only change the intensity of a light, but now they can change the color as well. When youre cooking over the grill, use a dimmer to intensify the light and cool its color, but when its time to dine and relax, use the dimmer to lower the lights and warm the color.

No matter how you do it, you want to create a space that people linger in, that they are drawn to, and lighting can help. Lighting can and should be a weaving together of colors, wattage and fixtures to create an outdoor space thats magical.

Outdoor Lighting: Finding your purpose - Billings Gazette

Georgie Silvarole , wltx 4:55 PM. EDT August 13, 2017

Glenn Brill hadn't even thought about the lights.

"My friend mentioned it to me, and he said, 'What are you going to do when the lights pop on?' and I hadnt even thought about it," Brill said. "As I understand it, they're all on photo cells so the street lights will pop on all over Anderson County when we have totality."

Brill, Anderson County's director of parks, recreation and tourism, has spent the last several months preparing the county for the total solar eclipse on Aug. 21. But it wasn't until a friend mentioned street lamps with automatic sensors that Brill even considered streetlights could put a damper on visitors' view of the eclipse.

Brill put in a request with Duke Energy several months ago to have the power cut at Green Pond Landing and Event Center on Aug. 21 for the duration of the eclipse.

The Black-Out at Green Pond is one of two events Anderson County has developed for people to view the eclipse. After the Green Pond event generated so much popularity, the county announced a second viewing location, the Civic Center of Anderson, in mid-July.

"Back in February, I made the request to cut the power to Green Pond, and that request is being honored," Brill said. "At the Civic Center ... I made that request in July and they had too many requests by then."

Randy Wheeless, a spokesman for Duke Energy, said the company is unable to meet the high number of requests they've received for the eclipse.

"We've received quite a few there's probably been dozens," Wheeless said. "As a rule, we're not really accepting those."

Though a few exceptions may have been made, Wheeless said meeting every request just isn't feasible.

"To cut off streetlights in any particular neighborhood is a manual process," Wheeless said. "It's very impractical for us to go and manually turn off those streetlights and then go back later and manually turn those lights back on."

Duke Energy simply doesn't have the time or manpower to meet each request to have streetlights manually turned off (and then back on again) all on the same day, Wheeless said.

"We understand the request, but from labor-intensive standpoint there's thousands of street lamps," Wheeless said. "You're talking about a pretty labor-intensive endeavor."

At the Civic Center, guests will be directed to the William A. Floyd Amphitheater, which will position them so the parking lot (and it's bright lights) will be at their backs, Brill said.

"We can turn off all of our outside lights, except for the ones in the main parking lot, and the amphitheater backs to the parking lot," Brill said.

More than 60,000 people are expected to visit the county on the 21st and thats the low estimate.

It could be as many as 245,000 in Anderson County, and as many as 2 million for the state, Brill said. Because of that influx, locals are encouraged to view from home if they can and if they choose to, they should try to cut the power to any security lights or outdoor lighting that might be activated by low light, he added.

"The reality is, if you're looking at the sun at this 63-degree angle, the lights shouldn't have too much of an impact," Brill said. "But for most people, this is a once-in-a-lifetime event."

Spain has been notorious for its incomplete cities and the overall infrastructure issues in some Spanish cities. Recently, a multinational technology integration company,Sociedad Ibrica de Construcciones Elctricas (SICE), has been working with municipalities to improve street infrastructure in two Spanish cities.

Mengbar (a city in the south-central province of Jan, Spain) is to receive a project that aims at replacing about 1000 points of light with LED lampposts, improving efficiency and energy savings of outdoor lighting systems. Santander, a city along the north coast of Spain, is also getting atraffic light priority system for public transportation.

SICE has built a reputation for saving up to 70% in electricity consumption and 20% in CO2 emissions.The project running in Mengbar aims to significantly optimize public lighting systems. Control equipment will be installed and integrated into the lampposts, reducing carbon dioxide emissions and annual electricity consumption.

While in Santander,SICE will install a Prioritization and Geolocation System, eventually giving priority to the public transport in the city via 17 traffic lights. The new system will enable intelligent wireless communication between priority vehicles and traffic light control elements while aiming at improving vehicle traffic.

The traffic light prioritization system is purposed to relieve the public transport from delays caused by traffic congestion at intersections controlled by traffic lights, which should reduce travel times and improve the services commercial speed.

When municipal buses get closer to a traffic light that is about to turn red, the system locates the buses on a GPS geolocation system to trigger the green light. Moreover, SICE will provide Santander streets with a queue jump (or sometimes called cutting in line).A queue jump system isa type of street infrastructure that provides preference to buses at intersections, often found in bus rapid transit (BRT) systems.

The system will be installed at three traffic lights, which will ease the incorporation of buses into the bus lane.
