Amoureux light bulbs produce light through heat: an electric current goes by through a thin filament, heating it up. The heat makes the filament white-hot, producing the light that you see. 90% of the power used to create the heat that lights an incandescent lamp is wasted.

Compact fluorescent light bulbs use a different technologies: they contain a gas that produces invisible ultraviolet gentle (UV) when the gas is put in the presence of electrical power. The UV light hits the white coating within the fluorescent bulb and the coating changes it into light source you can see. Because fluorescent bulbs don't use heat to create light-weight, they are far more energy-efficient than regular incandescent bulbs.

Based on the U. S. Department of Energy, if every household in the usa replaced just ONE regular incandescent light bulb with an Energy Celebrity approved compact fluorescent bulb (CFL) we'd save sufficient energy to light more than 3 million homes for any year, more than $600 million in annual energy expenses, and prevent greenhouse gases equivalent to the emissions of more than eight hundred, 000 cars.

Such a savings is possible because a fluorescent light bulb creates light using an entirely different method that is much more energy-efficient, in fact , 4-6 times more efficient. This means that you can buy the 15-watt compact fluorescent bulb that produces the same amount of sunshine as a 60-watt regular incandescent bulb.

ENERGY STAR competent lighting provides bright, warm light but uses regarding 75% less energy than standard lighting, produce seventy five percent less heat (cutting energy costs associated with house cooling), and lasts up to 10 times longer. They conserve about $30 or more in electricity costs over every bulb's lifetime, and are available in different sizes and shapes to fit in nearly every fixture, for indoors and outdoors.

As for drawbacks, CFLs don't operate well in frigid conditions, limiting their utilize for exterior lighting in cold areas. But the greatest problem with them is their mercury content. It's suggested to recycle CFL bulbs, since breaking or incinerating them releases mercury into the air. The poisonous metallic can then find its way into soil, water, seafood and fish-eating humans.

The mercury problem can be avoided via proper handling and recycling of the bulbs. Other than that, due to the fact lighting accounts for roughly 7% of the average lighting expenses (compact fluorescents will reduce that by over half), CFLs make sense for just about everybody, both financially and eco.
