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.

Outdoor lighting can be one of the easiest improvements that you can make to the exterior of your home, and it can make a huge impact. Not only will outdoor lights improve the way your home looks at night, but it can also increase the value of your home. If you wish to sell your home in the future, you will be able to add your exterior lights to the list of amenities that your home can offer potential buyers.

Some of the most popular places to add landscape lighting are along paths or walkways, and around patios or decks. Los Angeles homeowners often place outdoor lighting at different points throughout their flower gardens, too, which creates a beautiful setting for any summer evening. By placing small outdoor lights throughout the yard, it gives the impression of twinkling stars right in your own back yard. Landscape lights can be installed in many unexpected places, such as your own vegetable garden!

The Electric Connection, a licensed, bonded and insured local electrician in Los Angeles, can be a big help when it comes to deciding what type and style of outdoor lighting to use. They can also recommend where to place your lighting, and how far apart the lights should be. It’s always best to have this type of electrical lighting done by a licensed electrician.

Strategically placed outdoor lighting can be just the thing to help you make better use of your deck or patio, whether you’re spending time outdoors at night simply enjoying a quiet evening at home, or if you’re hosting a big party or a neighborhood get-together.

When it comes to the types and styles of landscape lighting choices that are available, there’s no need to worry because you’ll discover that there are plenty of options to choose from. For help and suggestions, you can find us on our website at TheElectricConnection.com.

Purchasing a new home can be both an exciting and stressful experience. While you may like what you see on the outside, we all know that there can be problems hidden behind the walls. When it comes to electrical, not only can improper work cost you lots of money, but it can also be dangerous. If you are browsing for a new home, make sure you are cautious of possible issues that can arise.

As we have written about in the past, the main service panel is a critical part of the home electrical system. This is what controls the electricity in the entire home. Over the years these panels can become old and worn. Sometimes additions may have been made to the panel, but not done correctly. When looking at a service panel it is important to look for any loose or wires and connections into the panel. The wires should be tight to avoid electrical outages and flickering. Loose wires can also cause sparking and lead to fires. An expert electrician can also identify the amount of wires going into each circuit breaker and the organization, which can help with safety and efficiency.

One concern many people have is what kind of wiring is behind the walls. Many of us have heard of aluminum wiring and that we should avoid it. The problem with aluminum wire is that the wires can become loose more easily and also heat up, becoming more prone to electrical fires. Old knob-and-tube wiring can also become weak, break easily, and cannot function at today’s standards. It is a good idea to have an expert electrician inspect the wires in your prospective home to make sure they are safe or whether they need to be upgraded.

Outlets in the home should also be easily tested. Check to make sure that none of the electrical outlets look burnt, dirty, or are loose. Outlet testers can be test to make sure that they are properly grounded and being fed electricity properly. It may appear that the outlets function properly and can continue to do so without being properly grounded. But in the event of a power surge, especially in a major appliance, the electricity will not escape through the grounded wire and can cause electrocution.

These are just some of the potential electrical problems that a home can have. In order to protect yourself and your investment, have a home inspector visit the home. If you have just purchased a home, have an electrician inspect it for any possible issues and for a more thorough analysis.

Since electrical work isn’t for amateurs, many homeowners don’t know much about the electrical systems in their homes. With all the wiring hidden behind the walls, it may be that all you know is what you learned in your pre-sale inspection -- if you remember, that is.

When it comes to electrical infrastructure, one attribute that sets homes apart is the type of wiring in the walls. And for several decades’ worth of older homes, that type is old-fashioned knob and tube wiring.

What Is Knob and Tube?

Knob and tube wiring dates all the way back to the 1880s, but it was still in widespread use as recently as the 1950s. For most of its heyday, it was the most economical choice for wiring a new home, both in terms of installation and cost of materials. But by the 50s, mass production of modern electrical cables offered a cheaper, safer alternative.

This type of wiring consists of two wires -- a hot wire and a neutral wire -- strung within walls and above ceilings using porcelain knobs and tubes. The tubes provided a safe place to run wires through studs and joists, and the knobs supported the wires and made it easy to wrap them around corners.

The wires are protected with sheaths. In the early days, these were made of treated cloth, but electricians eventually switched to rubber. Neither material was designed to last forever.

Is it Safe?

Electrical code prohibits the use of knob and tube wiring in most new construction, and homeowners insurance companies often won’t insure homes until they’ve replaced these systems. While it’s true that it’s not the safest choice, knob and tube wiring can still be used safely, but with limitations and special precautions.

One thing knob and tube wiring still does well is release heat. Because the wires are spread out and suspended in air, there’s lots of room for electrical heat to dissipate, which is good for energy efficiency and the wiring itself. But that also means knob and tube wiring can endanger flammable materials like insulation.

To safely use this wiring in any structure, you must be certain that all wiring is clear of flammable materials and that the system is well maintained.

What About Limitations?

Another risk with knob and tube wiring is that there’s no ground wire, which increases the possibility of electrical shock. It also means you can’t use any electronics or appliances with a three-prong plug, as the third prong connects to the ground wire. This inconvenience is often what motivates homeowners to upgrade.

But even where knob and tube can be made to work, homeowners may want to expand that system to other areas of the home. This often means splicing new wiring and fixtures into the existing system, which can lead to overloaded fuses.

A dangerous mistake is to simply upgrade the fuses when this happens. This will get the juice flowing again, but the wiring can get dangerously hot, and the protective sheaths may have deteriorated over their decades of service. It’s a fire waiting to ignite.

Stay Safe

If your home still has knob and tube, it’s important to have it periodically inspected. Even if it’s deemed safe, there’s no substitute for the safety and convenience of modern wiring. And if you’re not sure what kind of wiring you have, just reach out to your local, licensed electricians for a quick inspection!
