Compact fluorescent lamps (CFLs) are good substitute to the now being banned incandescent lamps. It is more energy efficient and lasts longer than its counterpart. CFLs are more expensive because the price includes the disposal fee. It was introduced in North America in mid 1990s. Although it is more energy efficient than the incandescent lamps, its composition makes its disposal complicated. CFLs are known to contain mercury which is a very serious threat to the environment once disposed improperly. Mercury functions as the vapor inside the glass tubing of CFLs. Usually CFLs contains around 3-5 mg of Mercury; some have it as low as 1 mg. In essence, Mercury is utilized as vapor in a phosphor tube, which when electricity pass through, it produces short-wave UV (ultraviolet light) which causes the phosphor to fluoresce, therefore making visible light.

Mercury or Hydrargyrum or quicksilver is a liquid metal with a symbol Hg. Mercury is a poisonous chemical that can be derived from major deposits as cinnabar or mercuric sulfide, the reason for vermilion, the red pigment responsible for the reddening of the soil. The poisonous substance can be ingested or inhaled mercury vapor or by eating mercury contaminated fish. Mercury poisoning which is also known as mercurialism or hydrargyria is the disease that can be derived from exposure to mercury or its components. Acrodynia, Hunter Russell syndrome and Minamata disease are among the list of those mercury related diseases. It affects body senses such as impaired vision, hearing and speech. Disturbed sensation and lack of body coordination are also among the symptoms.

Imagine the world full of mercury-filled CFLs, time will come that the number one cause of human fatality is mercury poisoning. Steps are being taken into account for the eradication of CFLs. By the year 2015, the government of the United States of America will implement the banning of use of CFLs to stop the possible exposure to mercury. Although it is expected that many users of CFL will stop this banning procedure, a lot of informative measures are being given to the public to further understand why the government is pursuing this act.

When this thing comes into action and given that the incandescent bulbs will as well be phased-out, what can substitute CFLs as lighting solution? Majority are thinking that LED lamps are the next thing to be on the spot light to cater all the lighting requirement of the world.

LED lamps can be considered a viable means as alternative to the prevailing lighting system which are expected to be obsolete in the years to come. LED lamps are a lot more beneficial to employ than those two. Imagine the comfort one can have if for a long time, around 10 – 13 years, he will not be thinking of replacing bulbs and maintaining it. Additionally, LED lamps are comparatively using very low energy and still can give-out the equivalent brightness and luminance compared to its counterpart. Considering the price of purchasing LEDs, one just have to consider LED lighting as an investment that will definitely pay-off in the years to come.

Ample information should have to be distributed to further inform the public regarding the practical benefits of choosing LED bulbs over the other lighting options available today.

Do me a favor and imagine that you are in need of suggestions for a Fourth of July party. You head to via Wikipedia

Of course, I’m not talking about snap pops, black cats, m-80s, or even those cool little paper cars that gush sparks, travel four feet, and then burn to death in a microblaze reminiscent of a 1970s action film.

I am talking about the ones that explode up there, the ones you have to tilt your head back to see. That the fireworks explode in the night sky is important because the very act of looking up immediately takes you out of the mundanity that the rest of the holiday will surely deliver – the planning, the decorating, the complications. No more overflowing trashcan with wing sauce-smeared cocktail napkins. No more ordinary stuff.

At the heart of the Fourth of July is a spirit of independence that is, actually, a big deal. When your eyes are on what’s going on at ground level, it can be hard to realize how big a deal ideas like independence and sacrifice are. Once your attention is arrested by the spectacle of fireworks happening up there in the sky, you’re taken out of the everyday and able to reflect on these things, which is important, I think.

2. They are glorious.

“And the rockets’ red glare/ The bombs bursting in air,” goes the song. Did you know that the word “rocket,” in the sense of the combustion-fueled projectile, dates all the way back to 1566? The Oxford English Dictionary notes that rockets have historically been “used for signalling, in maritime rescue, for entertainment, and as a weapon.” Fireworks symbolize communication, violence, and entertainment: A strangely fitting mix for the complex human heart.

The red glare of the rockets in “The Star-Spangled Banner” refers to the bombardment of Fort McHenry in the War of 1812. That the fort was not taken during the battle is indeed glorious, and fireworks are a reminder of the fortitude of the people who fought and suffered to keep America independent in 1776 and again in 1812. Boom. (Literally: boom!)

3. They are beautiful.

So, those are my three reasons that fireworks are the most important part of any holiday festivity: They happen above you; they are glorious; and they are beautiful. I think these are pretty good reasons for making sure you see some fireworks this Fourth of July.

Take a moment out of the hectic festivities to reflect on the spirit of rebellion, creativity, and inspiration that is involved in claiming and defending independence from parties eager to exploit the vulnerable. This is about more than just us. This unites us across time and space. Fireworks reflect the beauty of standing together for what is right, even when it hurts.

Electricity exists everywhere, from high voltage power lines to phones and computers. Understanding the basics of how it works remains essential to using it safely and efficiently.

When electricity travels from a positive lead to a negative lead in a circuit powered by a battery, it is considered direct current. This type of current powers electronics, LED lights, and cars. Alternating current is generated from rotation, usually by a generator. The direction of the current and the voltage flips as the generator completes a rotation. The faster the generator spins, the faster the flipping of current direction occurs. In North America, the typical frequency of AC power is 60hz or 60 alternations per second. The advantage of AC power is that the voltage can be stepped up easily by use of a transformer, which allows high voltage transmission. AC power is also useful for electric motors.

Specifically, power is a measure of energy usage over time. The standard unit of power is the watt and calculated as P (watts) = V (volts) x I (amps). Utility companies sell electricity in units of kW*h (kilowatt hours), which is simply one kilowatt of power delivered continuously over one hour.

high-tech smart bulb that’s trending in 2015 lighting technology. But in the late 1800’s it was the Edison bulb that transfixed the world as one of the most technologically advanced inventions of its time. In a practical sense, the electric bulb was the ‘smart technology’ of the 1800’s. Fast-forward a century, and the term Edison bulb holds an entirely new meaning.

In present-day design, Edison bulbs are vintage-style incandescent light bulbs with clear glass envelopes and visible filaments. You’ve probably also heard them referred to as antique light bulbs. Today’s reproductions are modeled after — you guessed it — Thomas Edison’s earliest light bulb productions. The exposed filaments (the string-like wires inside the bulb) are what set the Edison bulb apart from its 21st century counterparts like the LED.

It’s interesting to note that while historians agree that Thomas Edison Humphry Bulb doesn’t sound nearly as cool.

Today, when someone characterizes a modern bulb as being an Edison Bulb, they’re usually referring to a handful of common characteristics that these vintage bulbs inspire…
