On the topic of commercial lighting and products, we often hear the term Northeast Energy Efficiency Partnerships (NEEP for short), which is a non-profit that was founded back in 1996. There general mission is to accelerate the adoption of higher efficiency lighting within the world of commercial lighting products.

In conjunction with DLC, there is a group known as the Industry Advisory Committee (IAC). There general purpose is to support the mission of the DLC through education, collaboration, and expertise within the field.

So far you can probably start to notice that the DLC is basically all about efficient commercial lighting. But what role are they actually playing within the commercial lighting products industry? Well, the DLC runs something known as the Energy Star, but DLC is all about commercial products where Energy Star is more about consumer products.

On this Qualified Product List provided by the DLC, you can search up products by certain companies that claim to be DLC certified to confirm that they truly are.

While searching through this database, you may notice that some products are listed as “DLC Standard” and some as “DLC Premium.” Do you know which is better? You guessed it, the DLC Premium! The reason that a product being listed as premium rather than just standard is that to be qualified as premium you have to pass even harsher and more strict guidelines. Do you know what that means? It means even more efficient lighting fixtures for those products that have successfully been listed as DLC Premium.

Want to give it a test and see for yourself how this QPL works? Follow these simple steps:

1. Visit extremely helpful link over on the official DLC website that go’s over everything you need to become listed, standard or premium. As you can see on the official DLC website, becoming DLC Premium is only for the most efficient and quality lighting products.

Circuit breaker tripping might be something of an annoyance, especially when it happens at inconvenient times. Still, it is much better to have a circuit breaker that trips as opposed to one that doesn’t cut the power when it should.

Circuits can safely handle a certain amount of electricity, but we often don’t realize just how much of a load we’re putting on them. All too often we find ourselves plugging in one appliance too many, only to end up in the dark as the circuit trips! No one enjoys being in the dark, but your circuit breaker is doing the very important job of helping ensure the safety of everyone in your home. It’s important to understand what a breaker does and why it’s so crucial. It’s also vital to have an understanding of what it means when they keep tripping.

If your wires have more current flowing through them than they can safely handle, they could potentially overheat. This can lead to a few different outcomes. The wires could malfunction and lose their ability to work. This means repairs would be necessary before you’re able to utilize that particular circuit again.

Another possible result of excessive electricity is the melting of the protective insulation around the wiring, which leads to exposed metal wires. This exposure can cause fires, as well as an increased risk of electrocution. The circuit breaker should recognize when there is too much current present in the wiring. When the breaker detects excess electricity, it trips, cutting off power before the extra current can lead to any safety issues.

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 cost of many of the more traditional energy sources that we use, such as natural gas, gasoline and electricity are right there in front of us. Determining the overall cost of solar power, on the other hand, is not quite as simple. To make this process even more difficult, many of us have a hard time seeing not only the cost of solar panels, but the overall value. Unlike gasoline and other easily measured energy sources, solar panels provide their value over several years, rather than a few trips in the car.

How Much Do Solar Panels Cost?

In most cases, photovoltaic panels are priced by dollars per watt. Although many places will label things differently, this is the basis for most calculations. Whenever you purchase a solar panel system, you are essentially paying for the ability, or capacity to generate a certain amount of electricity, rather than a certain amount of energy to use until it is gone.

The overall cost of your solar panels will vary, depending on your individual project. Because each home is different, each project is different, making general quotes difficult. Furthermore, special tax programs that provide rebates and incentives can play a huge role in the cost of your panels. For an accurate cost, get in touch with solar installers in your area.

In addition to the varying costs of solar installation, are the various methods of purchase. The traditional form of buying panels outright and having them installed is less popular than it used to be. Many homeowners are now taking advantage of special financing for their solar panels. There are also many solar leasing programs out there, that we discuss at Solar panel Info. These programs allow you to lease a set of solar panels, and keep all of the energy that you generate. With all of these different options, generating solar power is much easier than ever before.

We’ve touched a bit on the subject of Do It Yourself solutions in the past. Mostly making mention here or there of when it is, and is not, a good idea. But at Kolb Electric, your safety is always our absolute primary goal. So rather than leave it at a mention, we wanted to take some time to tell you some important points. 

We support all kinds of on-your-own projects. It’s a great way to get a new skill set, or polish one you already have. Plus, nothing beats that feeling of accomplishment you get from creating or building something all on your own. But when it comes to DIY electrical work, we would firmly call it a really bad idea.

It really comes down to one major point: harm. It is entirely too easy to cause harm to yourself, to others, or to your personal property. If you follow along with our blog, you may remember a point we made in the article about “What It Takes To Become An Electrician”. In that post, we mentioned that anyone pursuing an education in electrical work pay very close attention to the safety aspects of learning.

This is because electricity, by nature, is highly volatile, and can be hard to predict without training. It only takes one, single misstep and suddenly you, or your home, is on fire. There are plenty of articles out there on how to wire an outlet, or replace a ceiling fan, but please be aware that 1) these articles are rarely comprehensive and 2) reading something and doing it are two very different things.

The U.S. Consumer Product Safety Commission has stated that roughly 400 domestic electrocutions occur every year. And of the estimated 360,900 residential building fires reported, the leading cause is electrical issues and mistakes. We really want to nail home the point that this kind of work takes training and experience to work well. Without these two things, you risk:

Fires that result in catastrophic property loss can even be caused by incorrect bulb wattage, so please keep in mind that something as intense as rewiring should be handled by a trained and certified professional.
