Reasons to Replace Your T8 Fluorescent Tubes With LED T8s

As LED technology advances and more LED lamps enter this world, there are myriad reasons why you should switch out your existing flourescent bulbs for the promise of energy efficiency. 

Take one of the most common types of lighting used in commercial settings: The 4-footer fluorescent lamps, which are beyond their prime and ready to be replaced with the newer, younger more powerful T8 tubes. Lets look at some common specs for the T8s.


T8 LED Wattage = 17-22 watts

Lumens = 1700-2200

Avg Cost = $65/each

Avg Life = 50,000 hours

Warranty = 2-5 years


....compared to the T8 fluorescent tubes.


T8 Fluorescent Wattage = 32-60 watts

Lumens = 2300-3100

Avg Cost = $3-6/each

Avg Life = 20,000 hours

Warranty = 1-2 years


Clearly, LED has a leg up in regards to lifespan. But does it really make sense to switch to these over the T8 fluorescents? In-short, the answer to that is yes! There is an old saying "You never know what you got till it's gone." Well this is clearly the case with the old T-12s fluorescent as the U.S Dept. of Energy bans those lights and phased them out of the market by 2012. This major change affected commercial, retail, and institutional business and even some home residents. This will eventually be the case with the T8 fluorescent. You're probably asking yourself, why? 

To put this in perspective, over a period of more than 20 years, legislation has become law that has continued to phase out the availability of most insufficient lighting-system-components (Lamps and Ballasts). Now there is numerous examples of the impact with this regulation. One example of this you might be aware of is the elimination of the 100 watt incandescent lamp in 2012, followed by the phasing out of the 75 watt incandescent lamp in 2013 and the 60 and 40 watt lamps in 2014.



1. Fluorescent Bulbs Contain Mercury


If a fluorescent lamp is broken, a small amount of mercury can contaminate the surrounding environment. About 99% of the mercury is typically contained in the phosphor, especially on lamps that are near the end of their life. The EPA recommends airing out the location of a fluorescent tube break. And of course, the broken shards of glass also pose a problem.

Any glass and towels used to clean up the area should be disposed of in a sealed plastic bag. Vacuum cleaners can cause the particles to become airborne, and should not be used. Scary, right?


2. Fluorescent Lights Give Off Ultraviolet Light


Ultraviolet emission from fluorescent lamps emit a small amount of ultraviolet (UV) light. A 1993 study in the US found that ultraviolet exposure from sitting under fluorescent lights for eight hours is equivalent to only one minute of sun exposure.

Very sensitive individuals may experience a variety of health problems relating to light sensitivity that is aggravated by artificial lighting. 

Ultraviolet light can affect sensitive paintings, especially watercolors and many textiles. Valuable art work must be protected from light by additional glass or transparent acrylic sheets put between the fluorescent lamp(s) and the painting.

3. The "Buzzing Ballast"  With Fluorescent

Magnetic single-lamp ballasts have a low power factor. Fluorescent lamps require a ballast to stabilize the current through the lamp, and to provide the initial striking voltage required to start the arc discharge.

This increases the cost of fluorescent light fixtures, though often one ballast is shared between two or more lamps. Electromagnetic ballasts with a minor fault can produce an audible humming or buzzing noise.

Magnetic ballasts are usually filled with a tar-like potting compound to reduce emitted noise. Hum is eliminated in lamps with a high-frequency electronic ballast. Energy lost in magnetic ballasts can be significant, on the order of 10% of lamp input power.

Electronic ballasts reduce this loss. Small lamps may use an incandescent lamp as a ballast if the supply voltage is high enough to allow the lamp to start.

4. Power Quality and Radio Interference

Inductive ballasts include power factor correction capacitors. Simple electronic ballasts may also have low power factor due to their rectifier input stage. 

Fluorescent lamps are a non-linear load and generate harmonic currents in the electrical power supply. The arc within the lamp may generate radio frequency noise, which can be conducted through power wiring. Suppression of radio interference is possible.

Good suppression is possible, but adds to the cost of the fluorescent fixtures.

5. Not As Efficient At High and Low Temperatures

Fluorescent lamps operate best around room temperature. At much lower or higher temperatures, efficiency decreases.

At below-freezing temperatures standard lamps may not start. Special lamps may be needed for reliable service outdoors in cold weather.

In applications such as road and railway signaling, fluorescent lamps which do not generate as much heat as incandescent lamps may not melt snow and ice build up around the lamp, leading to reduced visibility.
