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:

GE, Osram, Sylvania and Philips are some of the big names of lighting business. Look at how the market for modern energy efficient lamps is developing and one wonders if the lighting Industry is going the way the computer industry did.

When computers burst on to the scene, they redefined efficiency measures. A new computer was a considerable investment but it more than made up for its cost by increasing productivity or by reducing cost. Companies using computers could also use this fact as a branding tool – defining themselves as progressive corporations.

The demand for energy efficient lighting products has meant that incandescent bulbs now belong in a museum and not in homes and offices. LED lighting technology is quickly decimating old records of energy efficiency and long service life. The improvement in this technology render peak light output data obsolete every year. Energy efficient LED bulbs and tubes cost more up front but like computers more than make up for their cost through energy savings, lower maintenance costs and green branding.

This is how the computer business unfolded.

Given its strong technological capabilities, IBM was once the undisputed leader in computers. Then IBM made a decision that some call a strategic blunder. They outsourced their software development to Microsoft, which was then a small start up. Chip development became the forte of Intel. Soon IBM clones flooded the market. It was possible to buy chips, software and other components from different manufacturers and assemble them. These conditions created a fertile ground for entrepreneurs and many computer assembling and selling businesses came up quickly. Simultaneously, a host of software companies came up for developing specialized products like desktop publishing and anti-virus programs. Consumers benefited but IBM lost its dominance of the computer market.

Look at what is happening in the lighting industry.

This is how the LED bulb you love reaches your light fixture.

1.       Scientists in Universities, government funded labs and private companies work to break new ground in light output and longevity. They experiment with new semiconductor materials and manufacturing technologies to produce the best product at the lowest price.

2.       Using the knowledge generated in the labs, specialized companies like CREE produce High luminous output LEDs.

3.       Companies like ‘Seesmart’ excelling in fixture design assemble high quality LEDs into fixtures of suitable wattage and light output. They ensure that operating temperatures are low and light spread is even by marrying the best LEDs, optical diffusers and heat management systems. They also ensure that the lights are in accordance with UL testing guidelines.

4.       MyLEDLightingGuide understands LED lighting and brings these super efficient lights to buyers. We sample lights from multiple manufacturers and select those that make for the best price performance combination.

5.       Our secure e-commerce platform enables consumers to choose the product best suited to their needs from the comfort and safety of their homes and offices. They do not need to go through tons of brochures printed on paper or drive down to retail outlets. The chosen product is shipped to the buyer and helps him improve the performance of his/ her business or reduce home energy bills.

As with computers, new tech companies are coming up with pioneering technological products for remote lighting management and intelligent lighting controls. The parallels are too many and the business will probably develop as the computer industry did – adding efficiencies, earning foreign exchange and establishing world leading best practices in the bargain.

That LED light bulb manufacturers shall be the stalwarts of the new age of eco-friendly lighting is beyond doubt. GE, Sylvania, Phillips, Osram and other big names of the lighting industry are trying their hand at marketing LED lights. However, these big name lighting companies are going to face a lot of competition from smaller manufacturers and customer focused retailers like MyLEDLightingGuide. The reach of our E-commerce platform renders their distribution muscle redundant negating one the main advantages enjoyed by these big players. Intelligent customers do not choose brand name products blindly. Instead they like to see, study, analyze and understand evidence about the benefits of the product they have chosen to invest their money in. This is where our ROI calculator, data analysis and knowledge articles prove to be of great value.

The world of lighting seems ready for democratization.

Electric motors power everything from tiny electronics to massive industrial pumps. Yet, they all work on the same basic principles. Though AC motors seem ordinary, there are complex activities going on behind the scenes.

The simplest types of motors are three-phase AC motors. They convert a rotating magnetic field into mechanical rotation. The basic parts of an AC motor are the stator, rotor, bearings, drive shaft, and frame. The supply power is connected to coils of wire that are wrapped around laminated iron cores in the stator; the stationary part of the motor. When the coils of wire receive current, they generate a magnetic field known as poles. Each phase of power has the same number of poles; the poles are spaced evenly around the stator.

Historically, speed control of three-phase induction motors was very difficult. The only way to change the operational speed is to change the frequency of electricity supplied. Today, this task is accomplished by use of a variable frequency drive or VFD. This device is made of three main components: a rectifier, a DC-Link, and an inverter. The rectifier takes the incoming AC voltage and converts it to DC voltage that can be used by the electronics in the VFD. The DC-Link then uses capacitors to help smooth out the DC voltage from the rectifier and feeds it to the inverter.

The inverter then converts the DC voltage back to AC voltage. The inverter also controls the output frequency of the AC power by sending precisely timed pulses of DC power at specific voltages to rebuild the AC sine wave.

With a VFD, not only can the output frequency be controlled, but it can be slowly ramped up. This allows for smoother starting and can be adjusted to keep a motor spinning at a specific frequency. VFDs can produce three-phase power from a single-phase source, or even a DC source, to power highly efficient three-phase motors in locations without a three-phase supply. VFDs can also be incorporated into a PLC system to allow for automatic or remote control.

The combination of a VFD and AC motors offers a wide variety of functions and increased efficiency. Basic understanding of these technologies is essential for any electrician.

This summer is the time to plan plenty of outdoor events including backyard barbecues. If you have been thinking about having that new outdoor kitchen installed, now is the time to do it. Being able to stay outside with your guests as you prepare a fantastic feast is a luxury you can only get when you have an outdoor kitchen. Your outdoor kitchen would not be complete without electricity and lighting. You will need an electrician in Pasadena to help fulfill your dreams of cooking outdoors with all the modern conveniences of your kitchen. The team at The Electric Connection can help you achieve that dream.

One of the most important factors of your outdoor kitchen is the lighting. Many cookouts are held in the evening hours when things are a bit cooler because the sun is setting. With the setting sun, you will have less natural light. You don’t want to burn your meal and will definitely want adequate lighting for the cook. This can be installed by a Pasadena electrician. LEDs are an excellent choice and can be installed over the grill area to ensure the cook can see clearly.

Your counters, seating area and the walkway will also need to be adequately lit. You can choose to have lights installed along the pathway or have several large fixtures installed by an electrician. Pasadena homeowners have a number of different outdoor lighting options. You can choose soft lighting for the dining area or make it fun and festive with brightly colored lantern lights hanging over the seating area.
