Can I replace fluorescent tubes with LED?
Yes, you can replace fluorescent tubes with LED tubes or LED-integrated fixtures. If you just want to replace the bulbs, you can use plug-and-play, direct-wire, or hybrid LED tubes. Plug-and-play tubes are the easiest to install as they do not require any rewiring to the fixture.
How do I dispose of fluorescent tubes?
Fluorescent tube bulbs can generally be recycled at the same sites that take used CFL bulbs, but some retailers may not accept larger ones. Check Earth911 for your area and call ahead to be sure, or take your used fluorescent tube bulbs to your nearest household hazardous waste site.
What are the disadvantages of fluorescent lighting?
Fluorescent lamps are a specific type of gas-charged luminaire that produce light through a chemical reaction that involves gases and mercury vapor interacting to produce UV light inside of a glass tube. The UV light illuminates a phosphor coating on the inside of the glass tube which emits a white ...
What happens if a fluorescent lamp is broken?
If a fluorescent lamp is broken, a small amount of toxic mercury can be released as a gas, contaminating the surrounding environment. The rest is contained in the phosphor on the glass itself, which is often considered a greater hazard than the spilled mercury.
What is the difference between a fluorescent bulb and a compact fluorescent bulb?
Another difference is that linear fluorescent tubes require an independent ballast that is separate from the bulb whereas most compact fluorescent light bulbs have an integral ballast built into the base.
How does a fluorescent light bulb work?
Light that comes from fluorescent bulbs is omnidirectional. When a fluorescent bulb is lit, it scatters light in every direction, or 360 degrees around the bulb. This is grossly inefficient because only about 60-70% of the light given off by the lamp is being used and the rest is wasted. Certain areas tend to become overlit from the wasted light, especially in office buildings, and may require additional accessories in the light fixture itself in order to properly direct the output of the bulb.
Why do fluorescent lights age?
2. Frequent switching results in early failure. Fluorescent lamps age significantly if they’re installed in an area where they are frequently turned on and off. Extreme conditions can cause the lifespan of a fluorescent lamp to be much shorter than that of a cheap incandescent.
How long does it take for a fluorescent light to emit UV light?
Fluorescent lights emit ultraviolet light. In a 1993 study, researchers found that UV exposure from sitting under fluorescent lights for eight hours is equivalent to one minute of sun exposure. Health problems relating to light sensitivity may become aggravated by the artificial light in sensitive individuals.
Is fluorescent light better than incandescent light?
Fluorescents are typically a highly-efficient way to provide lighting over a large area, are more efficient, and last longer than incandescent bulbs; however, solely relying on fluorescent lighting is shown to produce negative ergonomic and health effects. 1. Fluorescent lamps contain toxic materials.
Do Fluorescent Bulbs Emit Dangerous Radiation?
There’s a common rumor floating around that fluorescent lights expose us to dangerous radiation that can cause cancer. The foundation of this rumor came from a 2009 study conducted by Canadian scientists who found that a compact fluorescent bulb, (CFL), gives off ultraviolet rays.
What about Migraines?
In a study conducted by the Cincinnati Children’s Hospital Medical Center, researchers noted that people who get frequent migraines are often “photophobic,” or more sensitive to light – and they may be more prone to suffering from a migraine as a result of exposure to fluorescent lights.
Do Fluorescent Lights Impact Your Sleep Pattern?
Some people have claimed that working under fluorescent lights for eight hours a day disrupts their circadian rhythm to the point where they can’t sleep properly.
Why are fluorescent bulbs good?
Fluorescent bulbs exist in a variety of shapes and sizes. The Good: Fluorescent bulbs and CFLs save energy. They are 75% more efficient than a regular incandescent bulb and they last longer. Saving energy saves money and conserves resources (ie fossil fuels) and reduces pollution. Sounds good!
How do fluorescent bulbs help the environment?
Overall, using fluorescent bulbs reduces mercury in the environment through the energy savings. Recycling fluorescent bulbs contains the mercury gas and (bonus) most of the components of the bulbs are recycled.
What happens when mercury bulbs break?
When the bulbs break, the mercury gas is released. The Ugly: Mercury contamination is widespread in our environment. This is in part due to natural occurrences but also legacy mining and energy production. Mercury can bioaccumulate in organisms such as fish.
Can you throw out bulbs in the trash?
There are some basic safety steps to follow if one is broken. Burnt-out bulbs should not be disposed of in the trash. Most bulbs break when thrown out, whether in the bin at home, in the truck, or at the landfill. When the bulbs break, the mercury gas is released.
Is mercury in fluorescent tubes bad?
So long as bulbs stay intact, the mercury gas is no threat. This means bulbs should be handled properly to avoid breakage.
Why do fluorescent lights flicker?
Flicker. Conventional fluorescent and LED light bulbs fluctuate in brightness many times per second because the alternating current electricity is not constant. This results in "flicker". Another cause of flicker is CFL or LED lights working on a dimmer switch without enough electrical resistance.
What happens if you need light late at night?
If you need light late at night or during the early hours, don't reach for the flashlight on your smartphone or your bedside lamp! These are high in blue light and will disrupt sleep.
Why are incandescent bulbs being phased out?
Incandescent bulbs have been largely phased out due to the advancements in technology, but they transformed our world in a big way. The lighting solutions used today are predominantly fluorescent and LED lights. They're long-lasting and more efficient.
Why is flicker invisible?
Due to the improvement in lighting technology, visible flicker has reduced and is now largely invisible to the eye because the fluctuations happen so rapidly. However, even if it's not consciously noticeable, flicker can still be picked up by the brain and it irritates the nervous system (2).
What is a fluorescent lamp?
Fluorescent lamps come in two forms -- old-school fluorescent tubes and compact fluorescent lights (CFLs). They consist of a phosphorous-coated glass tube containing liquid mercury. When an electric current runs through the tube, it excites the mercury which vaporizes and produces UV-light.
What was the only light that our ancestors had?
The only light our ancestors had was sunlight, moonlight and firelight. It allowed them to work from sunrise to sunset and spend evenings winding down. That all changed in the late 1800s.
When was the first light bulb invented?
Thomas Edison invented the first electric light bulbs in the 1870s -- known as incandescent bulbs. This bulb works by resisting electricity as it flows through an internal filament, heating it and radiating light (and plenty of heat). Unfortunately, these lights were inefficient, wasted energy and had short life spans.
Compact Fluorescent Lamps (CFLs) vs Fluorescent Tubes
Using Fluorescent Lighting
- In the past, fluorescent lights required a “warm up” period in-order to evaporate their internal gases into plasma. Several near-instantaneous starting technologies have since been developed, including “quick start,” “instant start,” and “rapid start.” As fluorescent lights heat up, more voltage is required for them to operate. The voltage requirement is controlled by a ballast—a magnetic d…
