Lighting is what has allowed our society to grow. Before standard lighting the day ended when the sun went down. Lighting offices and buildings with candles was highly inefficient, so the workday was over pretty quickly.
After the invention of the light bulb, civilization thrived and propelled industriousness and growth to maximum capacity. The light bulb of choice was an incandescent one, which basically uses a filament to heat a wire to produce luminescence. They were the most widely used solution for lighting throughout the 20th century and are still in use today.
They do suffer from a familiar issue: they are extremely inefficient. You do not need to be a leftist radical to know what makes economic sense and what does not. The incandescent light bulb uses approximately five percent of its power for lighting, and the rest is just heat.
Remember when a light bulb would go out? Whoever changed it always shook the bulb close to their ear. They were listening for the wire filament that burned off. Such a phenomenon is slowly going to be lost as the federal government of the United States is phasing them out. They are enacting a series bans on incandescent light bulbs and encouraging the purchase of compact fluorescent lights (CFL) and in some instances light-emitting diodes (LED).
Even some major retailers have stopped selling incandescent lights in the US. IKEA pulled the off the shelves in 2011. Congress surely has been lobbying many businesses to do the same since 2007.
CFL’s are becoming more and more common. The are those twisty bulbs that have no wire heating them up. It uses florescences by running a charge through phosphor gas which illuminates the bulb. It uses approximately 80% less energy than the incandescents. They even last up to fifteen times longer.
LED’s have been around since the late 1960’s and were common in alarm clocks and digital displays like those used on the trading floor on Wall Street. They perhaps emit the greatest white light. They also arguably have the best efficiency standards.
Lastly we can discuss halogen lights, which are those used in storm lights. These have not been banned… yet. For more information visit Energy Star’s website on all new regulations and information.
