T8 Vs T12 Fluorescent Bulbs - Time To Changeover To T8 Bulbs?

The topic of T8 vs T12 fluorescent bulbs has been a popular one in the last few years. Turn is something that always take time to wrap our head around. But with times changing and government regulations encouraging the more environmentally cordial and vigor recovery T8, it may be time to finally make the switch.

T8 Vs T12 Fluorescent Bulbs - Time To Changeover To T8 Bulbs?

T8 lamps or bulbs look very much like T12 bulbs in that they are both 4 feet in length, but they are smaller in diameter and run on less energy. So T8 vs T12 - which is better? And is it time to make a change? Let's take a closer look.

T8 Fluorescent Lamps Are More vigor Efficient

T8 fluorescent lamps part the same length as T12 lamps but they are smaller in diameter. This characteristic, together with good engineering, allows for T8 lamps to run with more vigor efficiency. T8 lamps run on 32 watts as compared with 40 watts for T12 lamps.

Even though there may be costs connected with retro-fitting current T12 fixtures to hold T8 bulbs, the savings in monthly vigor costs will offset that rather quickly.

T8 vs T12 Lighting

While T8 fluorescent bulbs run on less energy, it does not mean that they are less bright. In fact, studies have shown that they are slightly brighter than T12 bulbs. T8 bulbs were originally designed to shine just as brightly as T12 bulbs. In practice, this is found to be the case and even better. In one study, T8 was found to run at 2600 lumens, vs a sub-2600 level for the T12 bulb.

Another benefit is that T8 lights are found to maintain their glow great than T12 lights over time. Most light bulbs tend to decrease in their light yield over a period of time, whether they are T8 or T12 tubes. But T8 bulbs have tested to hold up great over time. T8s also last from 7,000 - 20,000 usage hours, which is plentiful.

T12 Bulbs Are Being Phased Out

Probably the most foremost calculate why it's time to move over to T8 from T12 lighting is due to regulatory changes. Like it or not, T12 ballasts and bulbs are being regulated out of the picture. It's only a matter of time before we need to make changes.

Already, the magnetic ballasts that powers most of T12 fluorescent bulbs are being phased out of yield currently. In an additional one 5 years or so, business observers are predicting that T12 bulbs will also ceased to be produced.

So very soon, when the existing T12 magnetic ballasts wear out, you will need to replace them with new electronic ballasts. However, it may be more sufficient to replace them directly with T8 electronic ballasts and bulbs at the same time.

If you replace them with T12 ballasts, you may still need to go straight through an additional one round of upgrading to T8 ballasts later on, since T12 bulbs would have gone out of production.

Time For A Change?

In the comparison of T8 vs T12 fluorescent bulbs, it appears that T8 bulbs offer great lighting with lower vigor costs. With upcoming regulations to phase out T12 bulbs, it is probably time to seriously consider development a change.

Led Lighting Vs Fluorescent Tubes - A uncomplicated query of health and vigor Savings

Led lighting is truly the next generation technology which features numerous benefits to not only consumers for Home Led Lighting, but businesses alike, with Led Downlighting products and Led Tubes which can replace out-dated, buzzing fluorescent lighting. Led lighting offers such benefits as a higher power efficiency than Cfls and fluorescents, lower power consumption, lower maintenance costs, longer lifetime (50,000 hours compared to less than 10,000), stamina and brighter light yield than conventional fluorescent lighting. Led lighting is gradually filling the Home Lighting and enterprise Lighting store place with such innovative products as Led T5 and Led T8 Tubes, Flexible Led Lighting, and Led Down Lighting.

Led Lighting Vs Fluorescent Tubes - A uncomplicated query of health and vigor Savings

Fluorescent lighting contains toxic materials such as mercury which is harmful to environment and human body. Did you know that if you drop or break a fluorescent bulb you must leave the room for 4 hours, due to the toxic materials floating in the air, which could cause respiratory damage, or Asthma in the long run for workers who have to deal with these fixtures daily. For workers and personnel who replace fluorescent tubes at work such as electricians are the most impressed by Led tubes, since they are not only easier to install, requiring no ballast, but they are worry-free, as they can last upwards of 10 years, on for 24 hours a day, and do not include any toxic materials like mercury dust that fluorescents do. For quick installation, Led tube lighting can be located and installed directly into existing fluorescent T5 and T8 sized sockets, you only need to remove the ballast, plug the Led bulbs in, and you're done! Contrary to favorite belief, Leds are very easy to install in this day and age, and the bulk of Led products are now "plug-and-play" while still contribution a slick look with unmatched power savings.

Although fluorescent lighting is more power productive than incandescent lighting, it is still an power wasting monster when compared with Led lighting. For businesses who have a large electric bill, switching to Leds could cut your power bill in half, while still retention all of the brightness, and no fluorescent flickering! Even with the most developed state of the art Cfls, fluorescent lighting accounts for a high ration in existing lighting all over the world, switching from fluorescent lighting into Led lighting can greatly sell out the global lighting power consumption and greenhouse gas emissions. Now let's do some detailed analysis to assess Led and fluorescent lighting, and there is no doubt that Led will defeat fluorescent lighting.

First of all, Led lighting is more power productive than fluorescent lighting due to the high efficacy of Leds. Leds for interior lighting have already broken the efficacy description of 100 lumen per watt, while fluorescent lighting only has an efficacy of around 60 lumen per watt. Led has a power factor of 0.9, which means most of the power is converted into light, but when fluorescent lighting works, a huge estimate of power is converted into heat which will be dispersed finally. Led lighting consumes only 30% power as fluorescent lighting to deliver the same lumen output.

Secondly, Flexible Led lighting has a much longer lifetime than fluorescent lighting since Led lighting is solid state lighting which more garage and reliable. Leds can last over 50,000 hours which means 17 years under general use. Whereas fluorescent lighting only has a lifetime of around 5,000 hours, which means you have to replace them as often. Using Led lighting can greatly save your expenses which are used to buy new light bulbs and pay for the labor.

In addition, the light quality of Led down lighting is much good than that of fluorescent lighting. Fluorescent lighting is always flickering when start up, while Led lighting is quick to start up without any flickering. We all know and have seen or live with flickering fluorescent tubes on a daily basis. They've really been proven to cause headaches, due to the micro-pulse wavelength they emit. Using Leds can sell out workplace strain, headaches, and increase efficiency, with workers at top performance, minus the migraines from Cfls!

When on for hours a day, for a long duration of time, fluorescent lighting may have some hot spots due to heat it generates, which does not happen to Led lighting. These hotspots cause the rest of the light to become dimmer, and fast results in a dead Cfl tube, a perfect reason to switch to Led T8 Tubes or T5 tubes, depending on the socket size. Fluorescent lighting / Cfl pigtails can cause eyestrain, but Led lighting does not as a supervene of its uniform and unparalleled balanced light output, and does not flicker or emit a low pitched humming like the earlier fluorescent technology. Today, Flexible Led Lighting, Home Leds, and Downlighs / Led Tubes are more eco-friendly than ever, beating fluorescent lighting by upwards of 500% - Translation: Savings on your power bill for both your home and office lighting fixtures. And of course, Fluorescent lighting contains toxic materials such as mercury which can cause air pollution if broken, and when thrown out and can cause permanent damage to the lungs and throat / skin if taste is frequent, or daily.

In contrast, Led lighting is solid state lighting which does not include any filaments that could break (like incandescent) or hazardous materials like Cfls. Person may say that the upfront costs of Led lighting is too high, due to the technology used to perform such a high lumens per watt (efficacy) rating, it is true. However, think about the long term power savings, and savings you will get from not needing to replace the lights, for up to 5 or 10 times as long, depending if the light substituted was incandescent or fluorescent. Either way, the more high power halogen, incandescent, or fluorescent lights you replace, the more money you will save every month. Some towns and states even have a tax-rebate / government agenda that pays you / reimburses you for power salvage Led bulbs. Check with your local town, half the bill could be on them due to up-to-date power grants and programs setup by President Obama in early 2010. Over the full life of the Led fixture / tube or bulb, the money saved by using Led lighting will be enormous? Why's that? When factoring in the true price of lighting, you must include all 3 variables: Upfront costs, maintenance costs, and a maintenance main to routinely replace your lights.. That is of course, if you aren't using Leds!

In my opinion, Led lighting will replace fluorescent lighting since it meets the requirements of sustainable development, incandescent lighting, due to power savings and durability, and halogen lighting due to the heat, security factor, and of course power usage! Replace your money hungry lights at the home, office, hotel, casino, college, dorm, or even your Rv to save battery power! Go green and truly be eco-friendly with Led lighting, and don't forget to Properly dispose of Cfl lights in a sealed garbage bag (or two, or your garbage mans health).

Fluorescent Lighting Dangers - Why Led Lights Are the better choice

Compact Fluorescent Lights (Cfls) along with more customary fluorescent lamps are now being aggressively marketed as environmentally cordial due to their reduced electricity consumption. Indeed, overall change of incandescent bulbs with Cfls will greatly sell out electricity demand; however, there are protection issues that finally lead to manufacture Led lighting the superior choice. Comprehension fluorescent lighting risks can help ensure that fluorescent light bulbs are used and disposed of safely while explaining why Led lighting is the safest and most eco-friendly lighting selection in the long run.

Fluorescent Lighting Dangers - Why Led Lights Are the better choice

Mercury

The most generally cited fluorescent lighting hazard is mercury. Fluorescent and Cfl bulbs comprise a small whole of mercury and are identified with the elemental stamp Hg. When these bulbs are cold, some of the mercury in the lamp is in liquid form, but while the lamp is operating or when the lamp is hot, most of the mercury is in a gaseous or vapor form.

Mercury vapor is extremely toxic. Even in liquid form, contact with mercury is determined life-threatening or a "severe" risk to health. Even very small doses of mercury can cause severe respiratory tract damage, brain damage, kidney damage, central nervous theory damage, and many other serious medical conditions.

Cfls mean less than 4 milligrams of mercury, about the whole that would cover the tip of a ballpoint pen. By comparison, older thermometers comprise about 500 milligrams, an whole equal to the mercury in 125 or more Cfls. Although the whole of mercury in each fluorescent lamp is small, it is all the time prominent to avoid breaking fluorescent lamps, and used bulbs must be delivered to a hazardous waste handler. Never place fluorescent lamps in trash compactors or incinerators, since this will release the mercury and contaminate the surrounding area.

Disposed of improperly, mercury can contaminate buildings, landfills, lakes, animals, fish, birds, humans, crops and rivers. In the Us, the Epa has ordered waste handlers to treat fluorescent lamps as hazardous waste. With such a classification, fluorescent lamps are not to be sent to landfills, but instead are to be sent to recycling centers that break the lamps under extra conditions and safely recover the mercury. Up to 95 percent of the mercury contained in Cfls can be recovered if the bulbs are recycled properly.

Mercury-containing lamps generated by households and small businesses are not all the time subject to legal restrictions regarding their disposal. State laws vary and some states, such as California, Maine, New Hampshire, Minnesota, Vermont and Massachusetts, prohibit all mercury-containing lamps, along with Cfls, from being discarded in the solid waste stream. In addition, many local ordinances wish recycling of mercury-containing products, along with lighting. It is best to check with your municipality to understand whether there are local requirements addressing mercury-containing waste disposal.

Because mercury will be released if a fluorescent lamp is broken, it is prominent to install fixtures in areas where the lamps are not likely to be broken. Fixtures in areas close to the ground or in areas with enthralling tool should use metal or plastic shields to protect the lamp from being broken. If a fluorescent lamp breaks, there are numerous protection and cleanup issues which we discuss in more information in the following section.

Breakage

Fluorescent lamps generate several hazards if broken. Depending on the type, there may be a partial vacuum or the lamp may be under pressure. Breaking the glass can cause shrapnel injuries, along with the release of mercury and other hazardous compounds.

The biggest immediate injury threat from a broken lamp is from the phosphor-coated glass. If cut with fluorescent lamp glass, any phosphor that gets into the wound is likely to preclude blood clotting and will interfere with healing. Such injuries should be treated seriously and immediate medical concentration should be obtained for population or pets that are cut. medical personnel should be informed that the injuries were caused by a broken fluorescent lamp, and that mercury was present.

To minimize exposure to mercury vapor, Epa and other experts recommend a few precautions. Children and pets should stay away from the area, and windows should be opened for at least 15 minutes so that vapors may disperse. Cleanup can be done by hand using disposable materials. Use rubber disposable gloves and scoop up the materials with stiff paper or cardboard. Use sticky tape to pick up small pieces and powder, clean the area with a damp paper towel, and arrange of the materials in an face trash can. Never use a vacuum because this will only disperse the mercury vapor and leave particles trapped inside the cleaner bag.

Dimmers

Never use a Cfl with a dimmer in the circuit (unless it is specifically made to work with dimmers), even if the dimmer is set at the maximum setting. Doing so places you at risk of fire and at the very least will dramatically shorten the life of the lamp and the dimmer. Also most photocells, appeal sensors and electric timers are not designed to work with a Cfl. Check with the manufacturer for the use of a Cfl for these types of fixtures.

To use a Cfl on a dimmer switch, you must buy a bulb that's specifically made to work with dimmers (check the package). Ge makes a dimming covenant fluorescent light bulb (called the vigor Smart Dimming Spirals®) that is specially designed for use with dimming switches. I don't recommend using regular covenant fluorescent bulbs with dimming switches, since this can shorten bulb life. Using a regular covenant fluorescent bulb with a dimmer will also nullify the bulb's warranty.

Finally, if a Cfl bulb "buzzing" when it is installed in a fixture that is controlled by a dimmer switch, this is an indication that you have the wrong type of Cfl bulb installed.

Electrical

Any fluorescent fixture that uses lamps longer than 24" or that is used outdoors or in a damp, wet, or high-humidity location must have an electrical ground for the fixture and ballast. All rapid-start and instant-start fluorescent fixtures must have an electrical ground in order to control properly. Fixtures with longer lamps control at higher voltages, with some fixtures having beginning voltages across the lamp as high as 950 Vac. Voltages at this level characterize a strong shock hazard and improperly grounded fixtures or direct contact with electrical connectors or other wiring can corollary in severe injury or death.

When servicing fluorescent fixtures and lamps, electrical power to the entire fixture should be disconnected. This is not all the time practical in situations where a large whole of fixtures are controlled from the same power control (such as in open office areas). In these cases, insulating gloves and a nonmetallic ladder should be used if the fixtures must be serviced when power is present. This guidance also applies when retrofitting a fluorescent fixture to mount Led tube lights.

Short-Wave Ultraviolet Light

A long-term hazard from fluorescent lighting is the shorter-wave ultraviolet (Uv) light that escapes the lamp. No matter how well crafted, some short-wave ultraviolet light escapes from every fluorescent lamp made. Short-wave Uv light is one of the damaging components of the suns rays that reach the face of the Earth, which can directly damage organic tissue and trigger cancers. Short-wave Uv light can also age or damage paper, fabrics and other materials.

Generally, fixtures with a plastic lens leak the smallest whole of Uv light, mainly because most of the ultraviolet light gets absorbed in the plastic lens. Fluorescent lighting in museums, archival libraries and manufacturing "clean room" areas normally have Uv-absorbing sheeting applied to the lamps or the fixture lens to eliminate all Uv light. Led bulbs do not yield any Uv light.

Flicker and Glare

Flicker and glare from fluorescent lights can also cause headaches and have been found to impact studying and capability to concentrate. Although humans cannot see fluorescent lights flicker, the sensory theory in some individuals can somehow detect the flicker. Ever since fluorescent lighting was introduced in workplaces, there have been complaints about headaches, eye strain and normal eye discomfort. These complaints have been linked with the light flicker from fluorescent lights. When compared to regular fluorescent lights with magnetic ballasts, the use of high frequency electronic ballasts fluorescent lights resulted in more than a 50% drop in complaints of eye strain and headaches. There tended to be fewer complaints of headaches among workers on higher floors compared to those closer to ground level; that is, workers exposed to more natural light experienced fewer health effects.

Long-term clinical studies that end fluorescent lighting in schools may be linked to many academic and health problems. A 2006 study found that students in schools with natural light instead of fluorescent lighting had a 10% to 21% higher studying rate and higher test scores. Fluorescent lighting may trigger headaches, migraines and other physical symptoms. Many children have been mislabeled with studying disabilities, Add/Adhd, reading problems and dyslexia all because of students having to work under fluorescent lights. With cool-white fluorescent lighting, some students demonstrated hyperactivity, fatigue, irritability, and concentration deficits.

Lamps operating on alternating current (Ac) electric systems yield light flickering at a frequency of 120 Hertz (Hz, cycles per second), twice the power line frequency of 60 Hz (50 Hz in many countries face North America). Essentially, the power is turning on and off 120 times a second (actually the voltage varies from +120 volts to -120 volts, 60 times or cycles a second and is at zero volts twice in one cycle). population cannot notice the flicker in fluorescent lights that have a flicker rate of 120 cycles per second (or 120 Hz).

Flicker is normally a potential question only with lighting that wish the use of ballasts, like fluorescent lights. Incandescent lights normally do not cause a flicker question since the light filaments generally do not cool swiftly enough (and make the light dimmer) while the "off" time as the voltage changes in the Ac power line. New, energy-efficient electronic ballasts take the 60 Hz power and change it to voltages at a much higher frequency. The resulting flicker frequency is so high that the human eye cannot detect any fluctuation in the light intensity - essentially flicker-free. An added advantage is that electronic ballasts yield less hum than that emitted by other kinds of ballasts.

Manufacturers and regulators have taken steps to eliminate this question with Led lights. In the Us, the new vigor Star criteria for integrated Led change lamps comprise a requirement for 150 Hz doing (now being challenged by manufacturers who cite studies that 120 Hz is sufficient). The majority of low-frequency Ac Led systems already control in the rectified mode, which effectively doubles the luminous modulation frequency to 120Hz for 60Hz mains in the Us. Despite many attempts, laboratory investigations have not found statistically valuable evidence of luminous modulation with frequencies over 100Hz on human performance, health, or comfort.
