A blog to keep sufferers out of the dark. We’re encouraged to use compact fluorescent and LED bulbs instead of incandescent bulbs, but are the long-effects of these new bulbs known, or can their effects be predicted? The results, "The Effects of UV Emission from CFL Exposure on Human Dermal Fibroblasts and Keratinocytes in Vitro," were published in the 2012 June issue of the Journal of Photochemistry and Photobiology. Anyone else using cfl bulbs aware of this issue? They don’t technically have a lot of ingredients that are overly harmful to the environment on their own merits. Sources: Harmful Effects of CFL Bulbs to Skin; Energy-Efficient Bulbs Safest When Placed Behind Additional Glass Cover. According to a 2010 Energy Star fact sheet, the net lifetime emissions for mercury is higher for incandescent bulbs than for CFLs. If the multi-colored wire is black and red, the black wire is the negative wire, while the red one is positive. An LED is a semiconductor diode that releases energy in the form of light when it’s switched on. They aren’t easily broken down, but aren’t harmful. CFL Bulb Life—Wildly exaggerated. But they can have negative impacts on … These lights are gaining immense popularity due to its ingrained beneficial features. Both linear and compact fluorescent lamps produce artificial light using the same technology. Compare that to 10 milligrams of mercury emissions released by the incandescent light bulb; the CFL has 3.6 less milligrams of mercury. So to prevent that use a better light bulb like a compact fluorescent instead of an incandescent light bulb. Posted by. But, the risks associated with mercury exposure can be minimized with careful handling and disposal of the broken pieces. These bulbs use less energy than traditional incandescent bulbs, they contain mercury, a substance that can be harmful to humans and to the environment. CFLs, aka, Chronic Fatigue Lights, use more energy than a regular light bulb, they threaten your health with mercury and electromagnetic radiation, and your government is forcing you to use them. T ABLE OF CONTENTS. u/PEJO89. Thousands of people are made ill from exposure each year. Kinds of light.
