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.

The average home contains 75 electrical outlets of different shapes, sizes, and functionalities.  Are the outlets that line your walls the correct ones for your home?  In this post, we are going to examine the most common outlet types in your home by pointing out the benefits and features of each outlet style.  Additionally, we will introduce you to some modern home outlet options that help keep your devices charged and ready to go.

The Fossil: 2-Prong Outlets

This type of outlet was the standard many years ago.  2-Prong outlets are 15 amp, 125 volt, 2-wired outlets which are commonly seen in older houses.  Since this outlet can only be used for ungrounded circuits, it is quickly becoming obsolete due to safety regulations and code limitations.

The Veteran: 3-Prong Outlets

When you think of an electrical outlet, chances are you are thinking about a 3-Prong, 15 amp, 125 volt outlet.  This outlet type is one of the most common home outlet styles currently available.  Easily recognized by its pair of long, vertical slots positioned above an upside down, u-shaped opening used for grounding the electrical current.  This important safety feature helps to prevent the risk of electrical shock in the event of loose wiring.

The Best of Both Worlds: Switch & Outlet Combination

This combination outlet offers two desirable features in one device.  Whether you are looking to install a new outlet device in your children’s rooms for safety, in the hallways of your home for nightlights, or on the kitchen counter for your appliances, the switch and outlet combo can give you that extra switch or outlet without any additional wiring.

The Safety King: GFCI Outlets

GFCI stands for “Ground Fault Circuit Interrupter.”  This outlet is named after its core feature, which is interrupting the circuit if there is a spike or leak in the current flow.  Current regulations mandate the use of GFCI outlets in areas that are close to running water.  You might have noticed some of these “GFCI Protected Outlets” in your restrooms, laundry room, kitchen, basement, and even outdoor living spaces.  GFCI outlets carefully monitor the flow of electricity, and when they detect that the current is flowing through an unintended path, the GFCI outlets will immediately shut off the electric power circuit.

These outlets can be identified by the presence of two small buttons in the center of the outlet labeled “TEST” and “RESET,” each being a different color.

The Mammoth: 20 Amp, 125 Volt Outlets

This outlet is reserved for the heavy-duty appliances and devices in your home.  While these outlets resemble the normal, 15 amp outlets, they are only intended for high current devices like your large kitchen appliances.  Too similar to the 15 amp outlet for you to keep them apart in your mind?  Remember that these 20 amp outlets have a horizontal slot attached to the upper left vertical opening of the outlet, while the smaller, 15 amp outlets do not.

The Craftsman’s Aide: 20 Amp, 250 Volt Outlets

Recognized by its unique design, the odd shape of these outlets is designed for specific types of equipment commonly found in a hobby shop.  For example, an air compressor would use this outlet type.

Whether you are looking to update your outlets for a modern look, or if you need a little more functionality out of your space, there are plenty of wonderful upgrade options that will fit your style and budget.

USB Outlets

With cell phones, tablets, laptops, and more mobile devices taking up your outlet space, doesn’t it make sense to add some dedicated USB outlets to your home?  USB outlets are a simple and functional way to ensure that everyone in your home always has a fully charged device.

Recessed Outlets

If all those gaps between your walls and furniture are bothering you, you do not have to stick with your standard outlets.  Recessed outlets add space to your home by eliminating the wasted space reserved for bulky cords and wires between walls and furniture.

Tamper Resistant Receptacles

These specialized safety outlets are characterized by a barrier that is intended to prevent children from inserting any foreign objects into the outlet.  These outlets are quickly becoming the new normal, as they are currently required by code in new homes.

Built-In LED Night Light Outlets

Plug-in night lights are fragile and could potentially harm a small child.  Keep those little fingers safe with a night light that is built-in to your electrical outlet.

Some winters pass quietly, others live in infamy. As one of the latter, this winter many of you may have had to resort to a “by any means necessary” approach to staying warm. Hopefully you had carbon monoxide detectors in your home to help you make it through safely. Manage without them? You might want to seriously consider the addition of these useful appliances.

Who needs a carbon monoxide detector? Anyone using any type of combustion heating such as wood stoves, fireplaces of any kind, gas and oil furnaces, in addition to gas appliances such as water heaters, stoves, and more. The incomplete combustion of fossil fuels such as coal, wood, charcoal, kerosene, propane, and natural gas used to power these items naturally produces CO (carbon monoxide) fumes. If you made it through this winter without a detector – great! But don’t push your luck. CO is the number one cause of poisoning deaths in the U.S. The Consumer Products Safety Commission (CPSC) reports 200 people are killed each year from accidental CO poisoning, with another 5,000 injured. Chimneys get clogged, appliances malfunction or suffer venting issues, and today’s airtight homes increase the chance of CO accumulation. In short, stuff happens – be prepared!

We love carbon monoxide detectors. Why?

How they work Though design varies slightly by model, carbon monoxide detectors use a CO gas sensor to identify and measure the concentration of carbon monoxide in your home in parts per million (ppm). When dangerous levels are detected, an electronic pulse is sent to activate the alarm – the higher the levels, the faster the response.

Are your carbon monoxide detectors safely installed?

Know the signs of CO poisoning so you can react quickly:
