In contrast to sunlight, artificial lighting does not provide the entire spectral curve, particularly in the infrared and ultraviolet wavelengths. If overdone, exposure to ultraviolet light can result in harm to the eyes or the human body. However, a small amount of near-range ultraviolet light is necessary for health. Fluorescent light doesn’t provide adequate spectra and can affect your child’s eyes and health in various ways, including a rise in headaches, arthritis, tooth decay, poor calcium absorption and seasonal affective...
More than 125 animal species synthesize some form of fluorescent protein, commonly seen in marine creatures displaying bioluminescence. Fluorescent proteins may be green, blue, orange-red, far-red, yellow or a combination of tw...
Both fluorescent and low-voltage halogen lightbulbs are popular alternatives to standard incandescent bulbs. Fluorescents challenge the primacy of incandescents because of their energy efficiency, while low-voltage halogens are...
Incandescent light bulbs have been around for more than a century, but newer technologies offer longer life and lower energy usage. Compact fluorescent lights have already become a common sight in homes across the country, but ...
Red dot rifle sights, also called reflex sights, or holographic sights, are compact, light and allow rapid target acquisition, which is why the U.S. military has adopted them in such numbers. The best red dot sights are rugged,...
Tube-style fluorescent bulbs have been a common lighting feature of schools and businesses for many years. When compact fluorescent lights became available, they began catching on for home use as well. These bulbs require about...
Compact fluorescent lamps, commonly called CFL bulbs, use up to 75 percent less energy than traditional incandescent light bulbs and last up to 10 times as long. The growing popularity of these money-saving bulbs has brought so...
As incandescent light bulbs are being phased out and consumers adapt to compact fluorescent bulbs, or CFLs, questions arise about the benefits of fluorescent bulbs. Technology allows manufacturers to offer cost savings to users...
Compact fluorescent light bulbs, or CFLs, are growing in popularity due to their energy savings. According to Energy Star, CFLs use 75 percent less energy and last 10 times longer than incandescent ones. It also estimates that ...
Fluorescent bulbs reduce energy consumption and lower operating expenses for homes and businesses. Unfortunately, these bulbs also contain between 3.5 and 15 grams of mercury each, according to the U.S. Environmental Protection...
Compact fluorescent lights, or CFLs, have emerged as an alternative to incandescent light bulbs. These bulbs are marketed as using less energy and lasting longer than standard light bulbs. Homeowners and business owners who wan...
Fluorescent bulbs produce improved light over incandescent bulbs of the past. The green movement has resulted in recommendations that consumers switch all their lighting needs to fluorescent bulbs because of the savings in ener...
Compact fluorescent light bulbs, or CFLs, are bulbs that use mercury to give off light. Mercury has proven to be the most efficient element in a fluorescent bulb to emit light, according to "Scientific American." Because CFLs d...
Compact fluorescent light bulbs, or CFL bulbs, are more energy efficient than standard incandescent light bulbs and therefore ease the burden on the environment, but the benefits don't stop there. Using CFL bulbs can put money ...
Compact fluorescent lights, or CFLs, reduce the energy needed for lighting by more than 75 percent. CFLs contain mercury, which is toxic. Normally, the mercury remains sealed inside the CFL. If a CFL breaks, don't panic. The am...
Although compact fluorescent light bulbs, or CFLs, originated more than 30 years ago as a response to the 1970s energy crisis, they were virtually unknown outside of hardcore environmental circles until the early 2000s. Today, ...
Home use was rare, except for low-end overhead fixtures. Fluorescent bulbs buzzed and cast a sickly green glow. With the introduction of CFLs, short for compact fluorescent light bulbs, all that changed. Dimmable and three-way ...
By reducing the amount of energy you use for lighting, you cannot only lower your utility bills, but also help protect the environment from pollution and global warming. Both LED and compact fluorescent, or CFL, bulbs require m...
Seasonal Affective Disorder, or SAD, causes many individuals to feel blue and lethargic during the winter months, says Medline Plus, a service of the U.S. National Library of Medicine and the National Institute of Health. Just ...
Fluorescent lights are coated internally with powdered minerals. They glow in many brilliant colors when their atoms are excited by ultraviolet, or UV, light. When you switch on the power, neon or argon gas, or a small amount o...
According to "The New York Times," LEDs are about five times as efficient as compact fluorescent bulbs and last up to 10 times as long. These bulbs cost very little to operate compared to other light sources, and produce very l...
This economic and environmentally conscious form of lighting can lead to both positive and negative health effects.
Compact fluorescent lights use less energy and last longer than incandescent bulbs. You might be reticent to make the switch, however, because of numerous published reports of potential dangers stemming from the bulbs. Many of ...
A compact florescent light bulb (CFL) produces invisible UV light and phosphor inside of the tubes to create visible light. These light bulbs can be easily recognized by their thin, tubular rods. Compact florescent lights are e...
