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.

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.

The bathroom serves as a place for many different activities. Your morning and evening routines start and end here and you rely on it to keep you looking your best. The importance of this room comes with the need to keep it looking, feeling and smelling clean. The best place to start with a clean bathroom is to install a bathroom exhaust fan.

You have most likely seen a bathroom fan in the past. The switch to them can usually be found next to the bathroom light switch. The reason they are so common in bathrooms is because of the activity that happens there. A bathroom without an exhaust fan can be airtight and offer little to no air circulation. When you add a hot shower and running water to this mix, you have a significant amount of humidity and moisture. If you do not deal with this moisture it can lead to mold and mildew, which can affect your health. The exhaust fan sucks the air from the bathroom and draws in new air, eliminating moisture and humidity in the process.

You can see the urgency and need for having a bathroom exhaust fan installed. But here are a few more reasons you might want to consider having one installed.

In many areas it is a requirement to have a bathroom fan installed, but that is not always the case. If you have a bathroom in your home without a fan then it is time to consider installing one before the damage is done. Because of the high moisture in the air you want to make sure that the exhaust fan’s electrical work is done correctly to prevent contact of moisture and electricity.
