So you are facility manager for a school, and you have been asked to replace old stadium lights for the football field, upgrade your stadium lights, LED has three basic advantages: reduction in energy consumed, reduced maintenance cost and a better quality of light.

LED vastly improves the quality of your sport fields and arenas. Not only do they create a higher standard in your facility, but they reduce the costs you are spending to light your areas on the back end as well. After the 3 solid reasons it’s time to upgrade to LED in your sports arena, I think you are well on your way to making the right and solidly informed decision when it comes down to purchasing your upgraded system.

How many light bulbs have you changed in your lifetime? It’s a simple action, and often one that we don’t put much thought into, but what if the simple act of changing a light bulb could make a profound impact on the environment, and the well-being of future generations?  As experienced Plano Electricians, we at ElectricMan Inc. have made it our mission to help bring knowledge of Alternative Lighting Solutions, electrical efficiency, and environmental responsibility to the forefront of everyone’s minds. The reality is that even small changes can yield huge benefits when it comes to energy savings. According to www.EnergyStar.gov:

“If every American home replaced just one light bulb with a light bulb that’s earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.”

Think about the changes that you can make by simply replacing the outdated incandescent bulbs in your home as they burn out with one of the Alternative Lighting Solutions below. Here are some details on a couple of the most popular Alternative Lighting Solutions available.

Compact Fluorescent Lamp: Modern CFL bulbs for use in homes consist of a curved fluorescent tube and electronic ballast in a single unit, designed as a direct replacement for standard blubs. They use 3-4 times less power than comparable incandescent bulbs. These are great options to replace your standard light bulbs, but they do have a few small drawbacks. According to an article by PopularMechanics.com, while CFL’s do have a much longer lifespan than standard bulbs, they often lose some of their brightness long before their expected lifespan is up, and this is increased in fixtures that don’t allow for efficient cooling of the ballast located in the base of the bulb. Another documented fact about CFL bulbs is that they do contain mercury, which means that they must be disposed of properly by taking them your local approved recycling center. You wouldn’t throw a battery out with the daily trash would you? So you shouldn’t throw these out either.

Light Emitting Diodes: LED’s are a form of “solid state” lighting that have become available recently to homeowners as an incandescent and CFL replacement. Using small light emitting diodes mounted directly to circuit boards, these are highly efficient, and have fewer parts prone to failure, allowing for an expected realistic lifespan of 20,000 to 30,000 hours, when operated at recommended temperatures. While initial costs for these bulbs are higher than incandescent and CFL options, long term energy savings are where this alternative lighting option truly shines, with the average LED bulb using approximately 12-17% of the energy that it takes to run an incandescent bulb of similar output, the end result is a bulb that costs drastically less to power over time.

As a point of comparison, here is a simple chart of the energy usage of LED and CFL bulbs compared to incandescent bulbs, and the output associated with them:

Lighting technology has changed a lot in the past decade, and it is pretty amazing to see what could be on the horizon for future lighting innovations. Take this for example. While most homes will never need this amount of output, it’s pretty impressive to see that something the size of a Christmas tree light, like this plasma bulb, can put out more light, more efficiently, than the giant bulbs that we use in street lamps!

The great thing about these changes is that they aren’t something that requires a huge change in your lifestyle, so they are some of the easiest ways possible to help the environment, and lower electric bills while you are at it!

LED fixtures, such as

With energy consumption that is less than half of what 150-watt LED parking lot light that is a direct replacement for 400-watt metal-halide (MH) fixtures. That’s 250 watts less for the same amount of light!

The average price of electricity per kilowatt-hour (kWh) is 12 cents. To figure out the monthly cost of running 25 LED parking lot lights for 11 hours per day, use this formula: (combined wattage x monthly hours of use)/1,000 x price per kWh. For 25 LED lights, (3,750 x 330)/1,000 x .12) the total would be $148.50 per month or $1,782 per year.

When the same formula is used for 400-watt MH fixtures, the monthly cost is $396, and yearly cost would be $4,752. So, in this situation, switching to LED fixtures would save approximately $3,000 per year. When coupled with the savings on maintenance, LED fixtures can save $6,470 per year. At that rate, the cost of 25 $340 LED fixtures would be recouped within two years.

Left: LED wall packs; Right: HID wall packs

Unlike LED fixtures that light up instantly, HID parking lot lights require a warmup period of up to 10 minutes before they reach full brightness. They also can’t be turned immediately back on after being switched off; this is called restrike time, and it can take up to 15 minutes before they can be turned on again. Attempting to power on the lights before the bulbs have cooled can damage a fixture’s components and cause the HID bulb to fail sooner.

HID lamps consist of a ballast and a quartz tube that contains gas, metal salts, and two tungsten electrodes. In order to create light, an electric arc passes from one electrode to the other through a gas (most commonly mercury, metal halide, or sodium). The mercury used in this process is dangerous if enough is inhaled or released into the environment. If an HID bulb bursts, all contents should be put into a sealed container or sealed bag and taken to a recycling center or hazardous waste facility. If HID fixtures are used indoors, wall packs and canopy lights, are used indoors, the possibility of ultraviolet (UV) radiation exposure should be taken into consideration. HID bulbs emit a substantial amount of UV radiation, but an outer glass envelope prevents the radiation from escaping. However—according to the FDA—”If the outer bulb breaks and the inner tube continues to operate unshielded, intense UV radiation is emitted. UV exposure at this level can cause eye and skin burns, as well as blurred or double vision, headaches, and nausea.” The UV light from an HID bulb with a broken envelope can also lead to discoloration of items and fabric. LEDs emit little to no UV radiation.

In short, LED lights are a better alternative to HID parking lot lights. They offer a great deal in the way of savings, longevity, maintenance reduction, brightness, color, and safety. While it may take a short amount of time to recoup the price of switching to LEDs, all of their qualities make it easy to see why so many businesses have started the process.
