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.

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.

Any building, in any industry, in any area of the world, is susceptible to having potentially hazardous and radioactive exit signs installed throughout their building.

This could mean they are in schools, near your office, or anywhere else where a radioactive setting probably isn’t a desired situation to be in.

This is why we thought it was necessary to create this post to help and guide you towards identifying, removing, and finally replacing your radioactive exit signs with new signs that are much safer and even efficient, saving you money over other alternatives.

Firstly before we can remove and replace these seemingly nuclear exit signs, you have to be able to identify if you have them or not. But before that, lets explain what exactly makes these exit signs radioactive.

How are some exit signs radioactive?

Just the same way as some exit signs are safe, it is all in the way they are built. For some reason, whether it be technology of the time or something else, people assumed it was a good idea to create exit signs with Tritium, also known as 3H or H-3. Tritium is a radioactive isotope of hydrogen, causing exit signs made with this to be radioactive by default. The only seemingly positive upside to these exit signs is that they are non-electrical, meaning they won’t rack up anything in electricity bills.

But before you become alarmed with what we have shared with you so far, tritium emits only a low-energy beta radiation, which in turn causes the sealed glass tube it is in to glow (causing the exit sign to give off the illumination it requires). Thankfully, it is rather well known that this type of radiation can hardly (if at all) penetrate a piece of paper or clothing. So while yes it is a very low level (energy wise) type of radiation, the fact that there are alternatives that will remove radiation entirely from your building is all the reason to uninstall your tritium exit signs and replace them with something more safe, like LED exit signs.

Now that you understand the technology and how tritium in exit signs work a little bit more, let’s go over how exactly you can identify whether or not you have these types of exit signs in your building.

Identifying a radioactive exit sign should be fairly easy. All of these signs are required to have some sort of “Caution of Radioactive Material” warning on the fixture.

If you do find such a warning label, it is safe to say your light is made of tritium. Another tell-tale sign is whether or not your signs are connected to an electrical source or not as tritium signs do not require any such connection.

Once you’ve identified if you have a tritium exit sign or not, if you do happen to have one, you may continue on to removing and replacing it with the alternative exit sign, LED.

As with any lighting fixture, we recommend to bring in a professional contractor to do the job. But as a general guideline, you can typically recycle your tritium signs by returning them to the manufacturer or place of purchase.

If you purchased the building with them pre-installed and are unsure of where they came from after inspection of the signs for any brand markings, you can try two things:

1: Try contacting the previous building owner or collect records of where they were manufactured

2: Recycle them with a third party. like these), buying them, then installing them yourself or with a professional (we recommend a professional).

Here are a few things you should remember and keep in mind when dealing with a building that has radioactive exit signs:

pursue electric lights.

A Timeless StyleIn the post-Victorian era, brass chandeliers shimmered with crystal drops and porcelain lamps were embellished with colorful floral themes. For members of the British aristocracy, the early 20th century was a time of elegance, luxury and opulence.

A quick glance through the latest designer catalogs are ample evidence that the decor of previous eras are still hugely popular. The style can easily be recreated with antique brass desk lamps. In contemporary homes, an elegantly crafted modern light fixture can give you the look of the most treasured antique.

Pay as you go electricity plans allow consumers to pay for their electricity in advance. The plan, which uses prepayment meters, helps consumers to monitor and control the way they use electricity. This saves on energy costs.

Keypad based prepaid meters: This meter has a keypad to input the electricity token number. Consumers purchase the credit using a variety of methods. These include visiting the agent, paying through banks or mobile payments in some countries.

Key meter: Consumer uses an electronic key loaded with the tariff information and credit.

One way card system: Uses a disposable card. The user purchases power with a reloadable debit card. The loaded card is then passed near the meter, which has an in-built card reader.

Two-way card systems: Uses a smart card and the meters have a real-time, two-way communication capability. It is one of the most secure, but more complex and expensive methods to implement.

These allow consumers to interact with their meters and query balances using their mobile phones by sending an SMS to a monitoring system. In addition, the user is able to track electricity use by the hour, day, month or annually using the phone or online access.

These smart prepaid meters offer easier top up options. They include online payments or by text, as well as scheduled and auto top-ups.

When using a prepaid meter, the customer must keep track of the remaining credits and replenish to avoid disconnection.

Ensure there is enough credit when going away for long periods. The meter will continue collecting the standing charges even when on no load. Consumers should ensure they have enough credit to last until they return.

Some crooks will take advantage of the consumer’s lack of knowledge and offer them cheaper credits than those bought directly from the utility company. For example, they will sell their credits at half price. This is more common with Key Prepaid Meters and the crooks will usually have master Keys, which they use to top off the consumer’s meter.

If the energy company finds out, the consumer ends up paying twice for their electricity; first to the crook, and then to the energy company.
