What better way to celebrate Independence Day than to do so in Virginia, one of the first colonies to create talks of revolution against the British? Virginia had a huge rule in the American Revolution. In fact, our first president of the United States, George Washington, was from Virginia! Thomas Jefferson helped expressed reason for colonial independence from Great Britain by writing the Declaration of Independence. The last major battle of the Revolutionary War was fought in Yorktown, Virginia and that victory led to the end of the war.

Virginians have a lot to be proud about for their involvement in the American Revolution, so you know we love to celebrate July 4th big! Our fireworks are always over-the-top and our parades are the best in the country. If you’re planning to celebrate big this Independence Day, consider these activities to do the weekend of July 4th. Make this Independence Day a day to remember!

We all know or at least heard that converting from Metal Halide (High Intensity Discharge) to LED will save you money.

But how much? Are there any other reasons or difference you should know about?

In this article, we break down all the factors that you should be aware of before making a decision to convert from Metal Halide to LED. Here are the 9 reasons we think LED wins over Metal Halide.

Let’s take a look at the information on a typical 400 watt metal halide bulb. While specifications may vary, a visit to a popular online website that sells Metal Halide bulbs shows that a brand new bulb has the following specifications:

We have just as many customers wanting to convert to LED because of maintenance savings as they do for energy savings. Think about what we discussed, over the life of the LED retrofit kit, a customer would have to do 5-6 Metal Halide replacements. The higher the installation height, the higher the cost of replacement. And if you have a facility loaded with lights, this becomes a significant budget amount every year that you must take into consideration. Now, we know that reduced maintenance time on lights does not translate into dollars saved because it is highly unlikely that people will lose their jobs over the fact there is much less work to do. However, these people will have time to now work on things that matter, like fixing the machines that make the company money instead on replacing lights that cost the company money.

When you take a measurement of light with a light meter, it reads lumens. And this measurement of all the lights that contribute to the light at that location creates a measurement called foot candles. But let’s think about that light that is being measured. Metal Halide creates all sorts of light, in all spectrum’s, visible or otherwise. This includes UV and IR spectrum’s, visible to the measuring device but not visible to the human eye. LED, on the other hand, does not produce UV and IR. Therefore, its readings using the same light meter is only picking up visible spectrum’s.

So there is a fun little test you can do. Have 2 light sources, LED and Metal Halide. And first ask, which one is brighter? And if the right LED source was selected, they should say LED. And then use a light meter, and the light meter may say the Metal Halide area is producing more foot candles. And so now you know part of the reason, but wait, there’s 2 other pieces of information you need to know.

Conclusion

A Look Back At 2011

Texas residents suffered damaging and costly electrical problems in 2011. Three major blackout incidents, two of which happened in the winter months of February and December respectively, left residents without heat and without power for hours and, in some cases, days at a time. Equally distressing was the 71-day drought that had Texans begging their local Dallas electrician for relief, as 100-plus degree heat waves weakened the power grid once again and left residents without air conditioning or electricity.

2012: Not Much Better

Unfortunately, 2012 does not seem to be the year for relief. Experts warn that several factors point to an even more severe blackout and power grid problem in the state of Texas for 2012.

 These factors translate into miserable, costly blackouts and power grid failures throughout North Texas.

Dallas Electrician Company Provides Solutions

There are some solutions for customers looking stay ahead of the game when it comes to protecting their home and appliances from the inconvenient and sometimes dangerous conditions that stem from power grid failures. With the help of a knowledgeable electrician, Dallas residents can acquire an indoor generator, which can serve as an effective emergency power source for your home or business in the event of a blackout.

One of the most convenient features of these indoor generators is that there is no need to use electricity to recharge the battery bank that runs the generator. Without the mess of a fuel-powered engine generator, customers can count on reliable and steady power output and a quiet supply of power for your appliances. Furthermore, the convenience of a solar-power or wind-power battery charge ensures that customers need not worry about using electricity to recharge generator batteries.

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.

Los Angeles is undertaking a quiet revolution, a switchover to electric cars. This is a revolution that promises bluer skies and greater freedom from foreign oil. At this writing, the Middle East is involved with its own, noisier revolutions, and the stock market is tumbling thanks to perennial shakes over skyrocketing oil prices. Everybody who wants to be independent of foreign oil right now, raise your hands!

Getting back to the other revolution, the quiet one, going on in Los Angeles… car makers and dealers, drivers, and electrical contractors are all involved in a switchover to electric vehicles (EVs). The government is backing it with tax credits and rebates. More on that in later posts.

In December 2010, Nissan started selling an electric car in L.A., the Nissan Leaf. Early this year, G.M. will start selling the electric Chevy Volt. This revolution isn’t confined to L.A. – all along the West Coast and some of the East Coast, deliveries of EVs to new owners are starting. But L.A. is out ahead of a lot of the rest of the country. The Leaf and Volt won’t go on sale, for example, in South Carolina until next December. Pike Research, a transportation analysis firm, has projected that only New York City will beat us out in electric vehicle sales. Pike Research projects 96,000 EVs will be sold in L.A. by 2017. Of course, EV sales could move faster if the price of gas shoots past projected levels.

Both the Nissan Leaf and Chevy Volt will be priced for middle income families. As electrical contractors in Los Angeles, we’ve already started installing chargers, including in home garages, apartment buildings, and commercial venues.

The Leaf is all-electric with an average range of 100 miles before its battery needs to be recharged. The Volt is a hybrid. With a fully charged battery, it can drive about 35 miles and then, it starts burning gas. Drivers can recharge their Leaf or Volt batteries by pulling out their special cord called a “Level 1 Charger” and plugging it into an outlet that carries regular house current.

The advantage of Level 1 charging is that it’s simple and inexpensive to set up. Hire an electrician to install a circuit in your garage or carport. It will need to be a dedicated circuit, meaning that no other appliances, like a washer, for example, will use it. The outlet will need to be the safety version usual in garages and outdoors (a GFI outlet). Also, your electrician will need to check whether your electrical panel should be upgraded in size to handle the increased power demand. Once the outlet is installed, the EV driver pulls out the Level 1 charging cord that comes with the car, starts charging, and lets the car sit … for a long time.

Level 1 charging is… well, slow. A Chevy Volt battery takes 10 hours from empty to full; a Nissan Leaf takes 20 hours. But help is on the way – Level 2 charging. More on that in my next post or click here for our article which talks about Level 2 Charging.
