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.

Indoor Generator Provides 20,000 Watts of Stored Renewable Energy to a Ranch Home, Even When All External Power Supply is Unavailable

Dallas, TX  December 30, 2011– Doug Kerr is the proud owner of a stretch of land located in the rural area of Kaufman County (Texas) where the air is fresh and the hustle and bustle of city life is non-existent. One thing Doug’s land doesn’t have, however, is a city power grid. Traditionally, to gain access to power in an area that hasn’t already been included on the electrical grid, you can pay the local electrical provider a large sum to run new electrical service to your location, or be forced to use noisy, polluting, and high-maintenance fuel-powered generators.

Fortunately, Doug found a much better option when he called ElectricMan Inc., a local Dallas and Plano electrician. ElectricMan Inc. is the exclusive North Texas provider of the Indoor Generator, a system that utilizes the latest technology in power storage, partnered with reliable renewable energy options to pioneer electrical independence not only for off-grid applications, but any residence or business that could benefit from more reliable electrical service and lower electrical costs.

Using a vertical access wind turbine, ElectricMan Inc. takes advantage of the abundant wind rolling across Doug’s land, from any direction, to provide a consistent source of electricity for the custom-built Indoor Generator unit installed in his home. The Indoor Generator system itself contains 20 maintenance-free deep-cell AGM batteries capable of storing 20,000 watts of on-demand power—enough electricity to run the household for an entire week or two, even if the wind doesn’t blow at all.

Keeping in mind that no matter how reliable your system is, a backup power plan is always important. The Indoor Generator is also compatible with an external gas powered generator that will run and charge the system at the same time in the event of an emergency, or the unlikely case that the wind doesn’t blow for an extended period of time. This is where the innovative versatility of the system makes it uniquely capable to reliably power a home. With thousands of programmable commands, the Indoor Generator has the capability to utilize multiple incoming power sources, and automatically switch between options such as grid power if it is available, stored battery power, wind turbines, solar panels, or a gas-powered generator, dependent upon what option is readily available and efficient.

The innovations that are integrated into the Indoor Generator system now give any home or business access to a constant supply of clean power, increasing safety, security, and longevity of electrical systems and appliances, while providing the opportunity for electrical independence to anyone.

This time forty-five years ago, history was made as a man stepped onto the moon for the very first time.

Imagine the anticipation as millions of people around the world held their breath and then felt waves of overwhelming relief at the sound of the words: “The Eagle has landed.” The culmination of work of many scientists, engineers, electricians and researchers came together in that single moment as everyone anxiously waited to watch Neil Armstrong’s historic hop from the spacecraft onto the moon. This event, and the following Apollo explorations, drastically propelled the development of modern-day technology. According to NASA, a surprisingly large list of technologies would not exist today without the Apollo explorations.

Freeze-dried foods, like the MREs used by the military and FEMA, were first invented for space travel. The same software of a retail card-swiping machine is similar to software that was designed to manage a complex series of systems on the Apollo capsules.

Medical imaging devices, TV satellite dishes, inner-ear thermometers and cordless power tools are a few more, plus smoke detectors and other fireproof materials. You can also thank NASA for the joystick video game controllers you use for Mario Kart and Nintendo 64, and of course, Pac Man.

Additionally, you can thank Apollo explorations for your laptop. Since more mass converts to more cost on board the spacecrafts, the scientists aimed to make everything as lightweight as possible, including the technology. This same idea translated into technology on earth, and the concept is still relevant today, hence the MacBook Air.

Also, where would the world be without the Moonwalk dance? Michael would have had to come up with another slick move for his music video. Space exploration has also led to world-renown literature and movie series, such as Star Wars and Space Trek. Not only did the moon explorations spark creativity, but they also inspired many people around the world to embark on a career in math and science to further new inventions and explorations and (metaphorically and literally) reach the stars in their goals and dreams.

We, of course, love lighting. Layers of light help to brighten any space, highlight certain aspects of a room, and help set the mood.
