Sport-Game Court Illuminated with Low Voltage Lighting

People who live in Colorado are very active and many families throughout Colorado have installed sport-game courts in their back yards for family fun. Many communities, however, have very stringent regulations as to the placement and usage of these courts. Additionally, many communities do not allow the courts to be illuminated in the evening with line voltage (120V) lights (typically 150W metal halide).

Several years ago a homeowner approached us in this predicament and we performed an evening lighting demonstration with our low voltage quartz halogen fixtures.

Our copper BB-01 copper flood lights with glare shields were painted black to blend in with the court’s fencing and netting – and the lights were conveniently controlled by the use of an all-weather switch next to the court. In previous years we have also illuminated a back yard ice rink in the mountains by mounting these same fixtures in trees and other strategic locations for very-spirited hockey games.

Our most recent installation was illuminating the sport court (with the Colorado Avalanche logo) shown at the beginning of the blog. Interestingly, the previous homeowner who had this court installed was one of the best goalies in NHL history – and he will forever be known in these parts as Saint Patrick!

The current homeowners use the court extensively and now they can actually see the volleyball net as well as the basketball nets at each end of the court! The low voltage lights and the anti-glare shields direct the light only where it’s needed – totally eliminating glare or light pollution into neighboring properties. As always with lighting, less is usually best in there’s absolutely no reason to light up a back yard court to the same lumen level as Invesco Field at Mile High. With this low voltage lighting system, the people using the court can see just fine thank you – without blinding their neighbors next door!

As with any home improvement project, homeowners need to peform their due diligence on prospective contractors (including landscape lighting) before any project is begun. Many homeowners ask why they should work with us and our response is typically “maybe you shouldn’t.” That response can be a bit disconcerting to most homeowners but almost immediately they understand the point we’re trying to make. And that point is that until you ask the right questions and receive the answers you’re comfortable with and do the background checks on a particular company or companies, you really should not be proceeding with any project until that due diligence is completed.

The following are some questions we’ve been asked over the years – and others that homeowners should be including as well:

BUSINESS LICENSING/REGISTRATION/INSURANCE?  Is the business registered and in good standing with the Colorado Secretary of State’s office? Does the company have the appropriate state and municipal operational and tax licensing? Does the company carry the appropriate property and liability insurance?

BBB RATING?  Is the company listed as an Accredited Business by the Better Business Bureau and what is its rating? For example, Outdoor Lighting Perspectives of Colorado is listed as an Accredited Business by the Denver-Boulder Better Business Bureau and currently holds an A+ rating.

HOW MUCH LIGHTING EXPERIENCE DOES THE COMPANY HAVE?  Outdoor Lighting Perspectives (OLP) of Colorado has been operating since 1999 – and our national company has been operating throughout the country since the late 1980s and early 1990s. Lighting is the only thing we do day in and day out – so we have to be really focussed and good at what we do. As part of a large national/international company with over 60 offices, we receive frequent and on-going training with respect to the latest lighting products and technology, design and installation techniques, and customer service. Interestingly, about 85% of the lighting companies operating in the Denver-Boulder area in 2001 are no longer in business.

HOW MANY LIGHTING INSTALLATIONS HAVE YOU DONE? The old saying is that anyone can sell you lights, but not everyone can provide you with an effective and high quality lighting installation. The number of installations a company has done is directly related to their level of expertise and professionalism in being able to handle any type of project. OLP of Colorado has close to 1,500 installations under its belt – from the plains of Fort Morgan to a two-mile high mountain-top and all along the front range of Colorado. Companies who only do lighting as a sideline business typically never get close to us with the breadth and complexity of the jobs we tackle.

CAN THE COMPANY PROVIDE REFERENCES? Good and reputable companies should never be reluctant to provide reference sites to prospective clients. However, from a lighting design standpoint every homeowner has different tastes and even different budget ranges in mind. That’s one of the reasons that we provide the free evening lighting design demonstration so that every design is customized for each homeowner.

WILL THE COMPANY PROVIDE A PREVIEW? As a follow on to the previous topic, any good lighting contractor should be able to provide you with an evening design demonstration so that you can see what the system will look like prior to the installation.

WHAT WARRANTIES COME WITH THE SYSTEM? Obviously, warranties are only as good as the company that backs it up. We once had a prospect (now a customer) who had asked one of our competitors “whose lifetime?” when he spotted their “lifetime warranty” banner hanging somewhat precariously in their exhibit. As I mentioned above, most of the lighting companies in business locally in 2001 are no longer around.

ASK ABOUT THE COMPANY’S SERVICE/MAINTENANCE PLANS Do they provide service after the sale? More often then not a lot of homeowners find out too late that the company that installed their lights provide no help after the installation.

FIND OUT WHO DOES THE ACTUAL INSTALLATIONS Does the contractor have their own factory trained employees or do they pick up day-hires with limited on-site training? Do they provide workmans comp, etc. Do they only hire and employ workers who are in the U.S. legally.

WILL MY LANDSCAPING AND SPRINKLER SYSTEM BE DAMAGED? Reputable and experienced lighting contractors should leave your property as good or better than it looked before the lighting installation was started. One of the best compliments our crews receive at the end of the day from a homeowner is that it looks like they had a lot more work to do since they didn’t notice any disruption to the landscaping. And that’s the entire point – the homeowner should not see anything different about the landscaping except for the fixtures as well as the beautiful illumination in the evening.

All of our trenching is done by hand with thin slices in lawn areas. After the wire is buried, the sod folds back over and most homeowners cannot tell where the wiring had been run. With regard to sprinkler systems, occasionally one of our crews does cut a line but it is our responsibility to fix it. If the sprinkler system is more complex than what we’re experienced with, we can call in one of several irrigation companies to complete the repairs.

Of course there are many more questions that homeowners can and should ask with respect to contractors in general and lighting contractors in particular, but hopefully I’ve addressed the primary questions today in this short blog.

Lighting for Veterans Memorial – Piney Creek Park

One of our most rewarding lighting projects was completed this week as we installed a new low voltage lighting system to illuminate a veterans memorial at Piney Creek Park located in Centennial, Colorado. The memorial consists of six flags – the U.S. flag as well as a flag for each of the 5 branches of the military – Army, Navy, Marines, Air Force, and the Coast Guard. The flush mounted well lights with 35W quartz halogen bulbs were installed with tempered glass lens covers.

Since a grass lawn surrounded all of the flag poles, the lighting fixtures were additionally protected by poured concrete caissons to protect them from lawn mowing damage, etc.

Veterans Memorial Lighting - Flags in Motion

Another photo to the right shows the flags in motion due to a brisk wind last evening. In fact when our crew was on site earlier this week installing the lighting, they experienced wind gusts approaching 70 miles per hour. In fact, the flag contractor was there at the same time to replace two of the flags which required that the flag poles be lowered to a horizontal position. Because of the wind, it took the flag contractor along with some of our crew to help raise the flag/flag pole back to a vertical position.

Back Yard Fire Caused by Overhead Power Line Being Snapped by Falling Tree

We design and install our landscape and architectural lighting systems to withstand almost everything mother nature can throw at them – from six foot deep snow drifts in the winter time, driving rain in the spring and summer time, and to salty environments in the coastal locations. But sometimes Mother Nature  lets you know that she’s really a force to be reckoned with.

On Monday of this week, the Denver metro area endured sustained winds of 45 mph with gusts to 70 mph- a few mph under hurricane force winds. I had been out in this wind with one of my crews and several times we almost got swept off our feet. Sure enough the phone rang several times the next day with calls from customers saying that some of their fixtures had been damaged by wind-blown debris.

The most major damage, however, was reported by one of our customers in the Hilltop neighborhood. One of his neighbor’s trees was blown over by the wind and severed the overhead XCEL power line causing the 80-foot tree to instantly become a fireball. One of the Kichler modernistic brushed nickel path lights can be seen in the photo below after the fire.

Thankfully, neither the homeowner’s family nor any of his neighbors were injured by the falling tree that was on fire or by the high voltage line that had just been severed. In fact, if you ever see a cut loose overhead wire on the ground or dangling from the air – NEVER, EVER approach it. Call 911 immediately so that the utilties can be called to cut the power as soon as possible. It may literally mean the difference between life and death to another unsuspecting passerby.

The other thing that happened was that the high voltage overhead power line sent a surge through the low voltage lighting system that in turn blew out the low voltage transformer and the GFI wall outlet. The good news is that our stainless steel transformers are designed and manufactured to code to be able to contain a catastrophic event such as this one. And the GFI outlet tripped and then failed preventing the outside surge from entering the rest of the house’s wiring system.

We just started our 12th year of installing lighting systems in Colorado, and this is the first time that we ever had an overhead line voltage power line get severed and then cause all of this other damage. After checking with our factory in Nashville, the folks there who have been doing this for over 20 years have never experienced a scenario such as this one. They have experienced damage to lighting systems due to lightning strikes but not from overhead power lines being severed.

Our Nashville office is currently dealing with the aftermath of the major flooding with respect to the repair and re-installation of entire lighting systems. And of course our New Orleans office is still dealing with the devastating effects from Hurricane Katrina. All we can do is to make our lighting systems as foolproof and as safe as possible, but sometimes Mother Nature reminds us who is really the boss.

Solar Runway Lights for Cars?

One of the worst lighting design mistakes is the creation of runway lighting by lining each side of a driveway or walkway with lights. Some neighborhoods give the appearance that the homeowners are leaving the lights on for the return of Amelia Earhart!

The other evening I was walking Cody the Airedale and snapped these photos with my camera phone. It’s bad enough doing runway lighting with low voltage or line voltage lighting fixtures. It’s even worse when some of the current inexpensive and low-powered solar lights are used. In the photo above, the fixtures are literally two feet apart. We totally love the use of solar photovoltaic/LED lighting when it’s done properly – but these inefficient standalone solar lights are ripping off the unsuspecting homeowner.

Solar Lights Used on a Patio

One the right is a photo of a patio being under-illuminated by standalone solar lights. There’s a fairly large dropoff from the patio down to the lawn – so you can see that these lights will not provide the proper illumination for preventing falls especially if there’s a party.

The photo below illustrates the proper way to illuminate a walkway. As you can see, the path lights alternate from side to side along the walkway. The other thing you’ll notice with this design is that other lighting effects are used as well. Uplighting is used to illuminate the columns of the pergola as well as the trees. This keeps the lighting effect appearing fresh and interesting and not monotonous – the way it would look if you just did path lighting.

Proper Use of Path Lights along Walkway

Most recently some townhome owners in Denver needed to share a low voltage quartz halogen landscape lighting system to illuminate their front entrances. The as-built configuration of the townhomes dictated that only one of the townhomes would have the low voltage transformer installed – and subsequently would have to provide all of the power for the entire lighting system. The respective homeowners agreed to split the annual electricity bill/usage for the system and asked me to compute how much that would be.

For this system, there were a total of two uplights (well lights at 35W each) and four path lights for the walkways (at 20W each) – for a total energy usage of 150W. For safety and security, the homeowners wanted the lights to be on from dusk to dawn throughout the year.

By accessing the U.S. Naval Observatory website and doing some computations, I was able to determine that there are a total of 4,306.29 hours of darkness for the entire year in Denver, Colorado. By multiplying 150W times 4,306.29 hours you get 645,943.5 watt-hours or 645.9 kWH. The average cost per kilowatt-hour in Denver is projected to be 11.3 cents through the year. By multiplying $.113/kW-H times 645.9kWH, you end up with a total operating cost of $72.99 per year, or $6.08 per month or $.20 per night. Most police departments will tell you that this is a small price to pay to enhance your home’s safety and security every night of the year.

Ken-Caryl House Lighting

The house on the left (also using a low voltage quartz halogen lighting system) has a total of 8 uplights (35W each) and 3 path lights (20W) each – for a total of 340W. Dusk to dawn operation costs $165.44 per year or $13.78 per month or $.45 per night.

If this same low voltage quartz halogen system is replaced by a low voltage LED lighting system in the future, the total power requirement would only be 80.7W and would result in annual energy costs of $39.26 per year or $3.27 per month or $.11 per night - a 76-percent energy savings over the quartz halogen system.

So in other words LEDs are the future but even with a low voltage quartz halogen lighting system, you’re still saving money with operating your outdoor lighting in comparison to line voltage lighting.

OLP of Colorado will be showcasing the latest energy efficient lighting products for illuminating community entrances, parks, clubhouses and common areas. LED, ceramic metal halide, and quartz halogen fixtures will be on display, and multimedia photos will show what actual installations look like after dark.

The event provides an opportunity for hundreds of community/HOA managers, property managers, and contractors to interact and attend the trade show and educational sessions.

Between the hours of 4:00 pm and 6:00 pm, friends, family and business associates of OLP of Colorado are welcome to come visit us (Booth #74) and stroll throughout the air and space museum to view the historical aircraft and aerospace exhibits. As a former aerospace engineer, I know I can’t wait!

We look forward to seeing you there!

At Outdoor Lighting Perspectives (OLP) of Colorado, we certainly emphasize the use of energy efficient lighting products such as low voltage quartz halogen, low voltage LED, line voltage Ceramic Metal Halide, line voltage induction fluorescent, and Lighting Control Automation™ for our residential and/or commercial customers. For interior lighting, Compact Fluorescents (CFLs) and LEDs are helping to greatly reduce homeowners’ energy usage as well.

Sometimes, even the little things add up. In OLP’s business operations we recycle copper wiring and the copper cores of low voltage transformers, stainless steel transformers, office papercardboard, and aluminum cans. For service calls and installations, we route and schedule our crews/vans to minimize travel time and mileage.  To improve fuel economy, we off-load unnecessary inventory/tools and ladders on roof racks before heading off to that day’s job tickets.

Examples of 1.5-, 2.0-, 4-inch diameter sleeves

Many homeowners this time of year are contemplating or even starting home improvement and landscaping projects, including new walkways, patios or driveways. With any type of hardscaping project, please make sure that sleeves are installed beneath any new concrete or brick pavers so that irrigation pipes/control wiring, lighting wiring, and speaker/sound system wiring can be installed at any time after the new hardscaping surfaces have been completed. Above you can see examples of the typical sleeve diameters used for most residential installations.

So what are sleeves exactly? They are heavy-duty polyvinyl chloride (PVC) conduits through which sprinkler irrigation and other wiring can be easily run whenever that phase of the project is ready to begin. Typically, hardscaping contractors will indicate the positioning of the sleeve(s) by a “vee”-shaped notch in the edge of a sidewalk or driveway for example. This saves a lot of work searching for sleeves as well as a lot of unnecessary disruption to the surrounding landscaping.

Since sleeves are relatively inexpensive compared to the increased time and labor cost of boring under a wide driveway, for example, my recommendation is to always install more sleeves than you think you’ll ever need. The other rule of thumb is not to use the same sleeve for both electrical wiring and irrigation pipes, for obvious reasons.

In fact today our crew was doing a lighting installation at a community entrance where the sleeve under the street has become a major headache. The original landscaper installed only one 4-inch diameter sleeve under the street – and then proceeded to run both the 2.5-inch irrigation pipe and all of the irrigation control wires through that same sleeve. Of course, the water and the electrical wiring should have been in separate sleeves. If that had been the case, our low voltage wiring could have easily been pulled through the wiring sleeve. As it is now, we’ll have to investigate other options including directional boring at $18 to $20/foot.

Community developers should also plan on providing line voltage power either behind entrance monuments or nearby to facilitate the installation of irrigation controllers, outdoor landscape lighting systems, and holiday lighting.

So the next time you’re planning an outdoor project, please do not forget the sleeves!

Well Light Requiring Cleaning/Vegetation Pruning

In Colorado, houses and landscaping get dirty through the winter months – and at the left is a photo of a well light prior to the AMP work being done. The lens cover is dirty and needs to be cleaned, the fallen leaves need to be removed, and the juniper needs to be pruned so that it does not block the light meant for the crabapple tree. Interestingly, last week we had a rain shower in Denver that left a deposit of reddish-tan dust on cars, house windows and landscaping – and the weatherman told us that evening that the dust had been carried all of the way from Mongolia!

Running an outdoor lighting system with dirty lens covers or lumen-depreciated bulbs is a total waste of energy. Imagine having to drive your car during all of the winter months without ever cleaning your headlights.

Quartz halogen bulbs lose roughly a third to a half of their lumen intensity on an annual basis. That’s why when the AMP is performed, all of the bulbs are replaced with new ones so that the lighting output and effect will be the same as when the system was brand new.

During the freeze-thaw cycles in Colorado and in communities with lots of active wildlife, it’s not uncommon for fixtures to become crooked or knocked out of place. Animals sometimes have a knack for pulling up wiring which also needs to be re-buried during the annual maintenance service.

Wiring That Needs to Be Buried

Wiring connections also need to be rechecked for tightness, especially in the transformer bays where internal temperatures can reach as high as 135-degrees Fahrenheit.

All landscaping has a way of maturing and spreading so that a well light that was properly located five years ago to light up a spruce tree, has now been swallowed by that same tree if proper maintenance has not been performed over the years. That’s one of the advantages of a low voltage system to be able to relocate the lighting fixtures as the landscaping matures.

Control systems for outdoor lighting systems should also be checked during this annual service visit. Even though low voltage lighting systems are very energy efficient, it does not make sense to be running the landscape lights an extra two or more hours a day during daylight hours if the system has not be set properly. That’s why we only use the Lighting Control Automation™ system for residential systems. There’s no mechanical timer to get out of synch because of a power outage or a photocell on a transformer that gets blocked by a roof overhang or tree that causes the system to turn on when it’s really not dark.

So either hire a professional or get out there and do the maintenance work yourself on your lighting system. Either way this annual maintenance will keep your lighting system at its optimum level for years to come.
