Transcript: Compact Fluorescent Lightbulb Fluorescent is the Present By: Laila, Marissa, and Antonio at "Fluorescent is the Present" What Is A Compact Florescent Bulb? What Is The Compact Florescent Lightbulb First of all before we get into the definition I want to ask you what type of lights you have at home. Stop and take a minute to think. If you have incandescent bulbs I suggest that you consider switching to CFLs. By the end of this presentation you will have no doubt about switching. The compact fluorescent lightbulb, also called CFLs, is designed and commonly replaces incandescent lightbulbs. The bulb uses a tube, which is curved or folded, to fit into the space of an incandescent bulb. CFLs are the number one bulbs to be used in schools and this presentation will show you why. Other Names For The Compact Florescent Lightbulb Other Names energy saving light compact florescent tube compact florescent lamp CFLs Are Not Just Spirals CFLs are now available in many different shapes and colors. You can find can find covered, reflector, and chandelier CFLs here at our company. We will help you find what style of lightbulb works for you. CFLs Are Not Just Spirals Benefits of CFLs Benefits of the CFL There are many benefits of the CFL which include: less energy is used on average (75% less energy than incandescent bulbs) Because less energy is used on average the cost goes down. They last longer so you aren't having to continuously replace and spend more money on them more environmentally friendly compared to the incandescent bulb. Just one bulb can can reduce half a ton of CO2 within its lifetime. meet specific requirements for electrical safety, fire, and shock hazard, meaning that they are very safe They produce very little to no heat unlike the incandescent bulbs Ultraviolet Emissions from CFLs are not likely a health risk more durable and don't break as easily. This is good because schools have many kids running around and your typical incandescent would break and glass would be everywhere They produce extremely bright light that spreads evenly 4 times more efficient than incandescent bulbs last longer than incandescent bulbs Video Video Disadvantages of Incandescent bulbs Incandescent lightbulbs disadvantage There are many reasons why you shouldn't purchase incandescent bulbs and here are some reasons why: -It is energy inefficient. -It has a very short lamp life time. Only about 1000 hours -It is a warm source of light, so air conditioning is need to cool down the room. -It has higher operating cost -It is very fragile so you must handle it very carefully -Since it requires a lot of energy it is harmful to the environment. Why our company? Why chose our company over anyone else So throughout this presentation we have showed you why, you should purchase the CFL rather than incandescent, but we have not made it clear why you should go with our company.

The other companies that may have the latest versions of CFLs have insanely high prices. We care about our customers and want you to have the best lights there are. Reviews Reviews Here are some reviews of past students whose schools have switched to compact fluorescent lightbulbs: ¨My classroom is a lot brighter now.¨ - Jonathan, age 14, Fairwind Public School ¨Our light are bright and work well ever since we switched to fluorescent lightbulbs.¨ - Amber, age 12, East Hill Public School ¨I walked into school yesterday and when I was in class I realized that I was not dying of heat. It was so much cooler. I asked the teacher why and she said because the new lightbulbs that we got do not produce heat." -Alec, age 13, Fairwind public school ¨My school is quite poor, so we can not afford much, but when I heard that we were getting new lights I realized that they must have been a great deal." -Jake, age 13, Berondale Public School Other Schools that we have sighed contracts with. Other school boards Our company provides many schools with compact fluorescent lightbulbs and these school have been pleased with our products. Here at "Fluorescent is the Present" we think that CFLs should be the only option for lightbulbs at schools. Just a few months go we signed a contract with the Peel School Board to provide them with our lights. Once all of the lights were installed we got many emails and videos from the students saying how much they loved the new lights. Also last week we just signed a contract with the Toronto District School Board and they have mentioned to us that they are enjoying our lightbulbs. From past experiences we know that schools need to be very cautious with what they spend their funds on, but once you sign with us you will leave knowing
Transcript: THE LIGHT BULB Antonio Sanchón Bailón An electric lamp or light bulb is a dispositive that produces light from electrical energy, this conversion can be done by various methods such as heating by Joule effect of a metallic filament, by fluorescence of certain metals before an electrical discharge or by other systems. Currently, there is technology to produce light with efficiencies of 10 to 70% What is it? What is it? Who was it invented by? On October 21, 1879 Thomas Alva Edison showed for the first time the electric lamp with a light bulb that was on for 48 hours. On New Year's Eve that same year, Edison presented in his laboratory in New Jersey a circuit consisting of 40 incandescent bulbs, which he himself turned on and off to the amazement of the more than 3,000 people who gathered. Just one month later, on January 27, 1880, Edison obtained the patent for the light bulb. Who was it invented by? At the base, they have two metallic contacts which connect to the terminals of an electrical circuit. The metal contacts are connected to two rigid cables which in turn are joined by a thin metal filament. Inside the light bulb there is a gas called argon. When the bulb is plugged into a power source, an electric current flows from one contact to another, through the wires and the filament. This produce the light. What is it made from? What is it made from? The light bulb is an object whose objetive is to produce light in a place where there ins´t any ligh and we want to see there. What can it do: What can it do: 1. Halogen lamp: around the year 1940 appeared on the market the revolutionary halogen lamp, the evolution of the incandescent bulb that consisted of a tungsten thread wrapped by halogen materials heated to produce light 2. Fluorescent lamp practically on a par with the halogen lamp, fluorescent lighting was put on sale. I consisted of a glass tube with tungsten filaments at the ends that revolutionize the atoms of chemical components inside them to radiate light. 3.The LED: at the end of the 20th century it was invented and works at low voltage. Nowadays we have this light bulb on the market. How has it changed over the years? How has it changed over the years? Video
Transcript: Thomas Edison devolped a light bulb with bamboo filaments. The improved lightbulb lasted 1200 hours! positive impact to society?
