Although LED T8s have not been around long enough to produce a thick memoir, there are some interesting things to note about why they exist.  A few years ago, there was concern that the rare earth metals used in fluorescent tube lamps might start getting significantly more expensive for the U.S. to purchase from China. Light bulb manufacturers began an arms race to develop an affordable and effective LED T8 replacement tube.

A sustained sharp increase in the price of phosphors never really happened. And so LED T8s have gained momentum in their evolution, organically evolving to better perform well in certain applications. Their price point has decreased, and their performance has gone up. And now, LED T8 linear lamps are certified by the DesignLights Consortium to be high quality, high efficiency lighting products.

However, LED T8s continue to be very controversial – even divisive – in the lighting world. Many people think they’re great; but some people think their existence is entirely unnecessary. Both sides of this argument tend to contextualize their visions of the merits and pitfalls of the LED T8 in a comparison with the merits and pitfalls of the traditional fluorescent T8 tube light.

LED T8 Linear Light Bulbs vs. Fluorescent T8 Linear Light Bulbs

First of all, the merits of fluorescent T8s cannot be overstated. Fluorescent tube lamp technology has been developed over decades and is now basically mastered. Fluorescent T8s are extremely inexpensive and have ridiculously long rated lives. In fact, in some cases, fluorescent T8s can last as long as LED T8s!

And it doesn’t stop there. The production of light with fluorescent tube lamp technology works really, really well. It is probably at its peak in terms of performance and cost. Fluorescent T8 light bulbs can last 50,000 hours. And despite their not-always-positive reputation for rendering color, fluorescent T8s can achieve high color rendering indexes (CRIs). But, it must be clearly noted, fluorescent T8s get more expensive as you seek a higher CRI.

And in terms of cost, let’s just say it straight: In many applications, the LED T8 tube light’s initial cost doesn’t make sense when compared to the relatively low cost of fluorescent T8s.  For example, at this stage of the game (June 2014), lighting large spaces like classrooms or large offices is job better performed by fluorescent T8s than LED. First, there’s the cost. Fluorescent tube lamps last long, cost little, and give off crisp light. Furthermore, fluorescent tubes give off light omnidirectionally, casting light upwards toward the ceiling as well as downward. This makes a space look more fully lighted. LEDs, in contrast, are generally more unidirectional and cast light downward only. This is something that will change, but, currently, this is just affirmation of the fact that fluorescent T8s reign supreme for some applications.

Fluorescent T8s often take a while to come on; they’re adversely affected by temperature (and somewhat sensitive about it); they can flicker often; and if the lights are turned on and off frequently, as in laundry room or bathroom applications, for example, they can fail quite prematurely, to the dismay and annoyance of everyone involved. And then there’s that toxic mercury vapor which poses danger to humans and the soil on which we live.

Oh yeah, fluorescent tube lamps require a ballast, too: A component that will also, eventually, fail.

Now, let’s give some attention to LED T8 tube lamps. It should first be noted that LED T8s have a higher initial cost than fluorescent T8s, which can be purchased for only a few dollars in some cases.

Despite their higher cost, LED tube lights have some nice advantages. First of all, LEDs love the cold, so they are great in cold weather applications, unlike fluorescent T8s, which become seemingly infirm in the cold, slow to turn on and flickerish. Basements, sheds, garages, porticos, covered pathways, bathrooms, etc, are great places to utilize the LED T8 linear lamp.

You also have to consider that if an LED T8 tube breaks, it will not release harmful mercury vapor into the air. Mercury from fluorescent tubes can get into the air but also the water supply, which is why you have to recycle them. For some people, the whole mercury thing is enough to open their minds to alternatives to the long-reigning fluorescent T8.

Plus, you can get better color rendering with LEDs than with fluorescent lights. Fluorescent lights work by transforming ultraviolet radiation into visible light. If you have a vague idea about what UV light is, you know that it’s the part of the light spectrum that’s just past the blue and violet area. Even with a rudimentary understanding of light, then, it’s easy to see how the result of transforming UV light into visible light would leave you with a bluish result. As a result, in general, fluorescent lights do not render reds well.

LEDs exude very little to no UV or infrared radiation, both of which fade the color of displayed objects including wall art, furniture, and even rugs. Fluorescent tubes – did you know this? – do indeed fade sensitive belongings over time.

Finally, LED tubes do not generally require a separate power supply. They run on line voltage and require no separate drivers, ballasts, or transformers. That’s one less thing that can break. In conclusion, LED T8s are more expensive than fluorescent T8s, but LEDs are safer, render color better, require no ballasts, operate better in the cold, and do not decline significantly in lifespan due to frequently switching on and off. This means that there are some applications, like cold places, bathrooms, basements, laundry rooms, kitchens, closets, storage rooms, walk in refrigerators or freezers, or places where there’s a risk of broken light bulbs like gyms, warehouses, etc, for which LED T8s might be the better choice. And since LED T8s don’t weaken with frequent switching on and off, they are great for use with occupancy sensors.

When you are purchasing a home, it goes without saying that you want to be sure the house is structurally sound, and that there are no lurking problems that will surface later and burn a hole in your pocket. It’s why many people get a building inspection and pest inspection done before they sign on the dotted line. While all of this sounds good, what most people aren’t aware of is that they can and should get an energy audit done too.

An electrical audit analyses the major components of the house structure; this includes:

In short, it gives you a very detailed picture about how the buildings works as a whole. For a couple of hundred dollars, you can get an energy audit done from a professional. This audit can save you a significant amount of money in the long term; it identifies the features in the house that require correction to enhance the energy-efficiency. At times, the energy audit results can play a pivotal role in your decision of whether you should invest in a particular property or not.

If you find that a house lacks in energy efficiency, but you still want to buy it, the audit results can become a bargaining tool; it may help you get the seller fix the problem, or you may be able to get the property at a much lower price. No matter which way you look at it; getting an electrical audit is a very good idea. In addition to the ones mentioned above, there are a number of other benefits to getting an electrical audit done, such as:

The simple fact is that spaces that are energy-efficient are also more comfortable to live in. Energy-efficiency upgrades will ensure that the heat will be evenly distributed across the home and your home will be warm in the winter and cool in the summer.

If the indoor air quality in your home is poor, it can cause allergies as well as other health problems. When you choose to get an electrical audit done, the professionals that are conducting the audit, carefully analyse the ventilation in your home and also recommend what can be done to improve the indoor air quality.

Energy efficiency may seem like an isolated aspect in the sustainability of your home. But when discrepancies in the building structure come to the fore during an energy audit, it’s indicative of the fact that many features are constructed poorly and that they will fail before their time. Once you have the audit results, you will get a clearer idea about what will have to do be done to improve the building envelope as a whole.

When you are hiring the services of an electrical/energy auditor, you should keep in view the fact that not every one of them uses the tools and follows the required processes while the audit is being conducted. Ideally, the auditor should use tools such as a duct blower, an infrared camera as well as a blower door.

The blower door is essentially a fan that has to be mounted on the doorframe. It efficiently depressurises & pressurises the home to measure what the air leakage is like. The duct blower performs the same function, but is attached to the ducting in the house. The infrared camera helps detect air leakage in the walls and the heat losses too.

You work hard to keep a roof or your family’s head and you want to protect them while they are at home. You probably lock your doors and windows at night and leave a light so nobody trips when making one of those late night bathroom runs. Is there more you could do?

Carbon Monoxide and Smoke Detectors

You can add an extra layer of protection to your home for your family by having smoke and carbon monoxide detectors in the home. An electrician in Beverly Hills can hard wire a smoke detector into each room of the home. This is an ideal option, because you do not have to worry about batteries going dead or being “borrowed” for some toy or remote. The detectors rely on your home’s electricity. Of course, you will still need to have a battery powered detector in the home. In most models, the electric powered detectors also have a battery backup option.

Hard wired smoke detectors should be placed in every room somebody sleeps in as well as the basement if you have one. The detectors can be interconnected, so if one goes off, they all go off, alerting occupants to a fire. This is an ideal option for those who like to sleep with their bedroom doors closed.

Carbon monoxide detectors should also be installed by an electrician. Beverly Hills homeowners should absolutely have one of these detectors in their home to protect themselves against the odorless gas, carbon monoxide. As with the smoke detectors, an electrician will hard wire a carbon monoxide detector on each level of your home. These can be interconnected as well.

If you use a gas stove or have a garage connected to your home, you will definitely need to consider having a carbon monoxide detector. You can rely on The Electric Connection to get this extremely important job done for your family.
