Thesis: In order to save money and cut costs, it is imperative that one uses different kinds of energy-efficient lights. * Light Fixtures
* Light fixtures are the devices that hold the light bulbs you use * In order to have a light in your house you have to have a light fixture to hold it. * Since there are many different types of light bulbs there must be different light fixtures * I.e., fluorescent, LED, and your basic incandescent, etc. * Light Bulbs
* Light bulbs are what give you that wonderful emission of light. * Light bulbs vary from different sizes to different shapes and different colors * They also are rated different wattage and voltage * Depending on the bulb these key factors could jeopardize your energy bills * Types of Light Bulbs
* There are several types of light bulbs that are used for different reasons * Incandescent Bulbs- these are the standard bulbs that most people are familiar with. Incandescent bulbs work by using electricity to heat a tungsten filament in the bulb until it glows. The filament is either in a vacuum or in a mixture of argon/nitrogen gas. * Halogen Bulbs- halogen bulbs are a variation of incandescent bulb technology. These bulbs work by passing electricity through a tungsten filament, which is enclosed in a tube containing halogen gas. This halogen gas causes a chemical reaction to take place which removes the tungsten from the wall of the glass and deposits it back onto the filament. This extends the life of the bulb. * Fluorescent Bulbs- These bulbs work by passing a current through a tube filled with argon gas and mercury. This produces ultraviolet radiation that bombards the phosphorous coating causing it to emit light. Bulb life is very long - 10,000 to 20,000 hours * Compact Fluorescent Lamps- compact Fluorescent Lamps (CFLs) are a modern type of light bulbs, that work like fluorescent bulbs, but in a much smaller package. Similar to regular fluorescent bulbs, they produce little heat and are very efficient. They are available to fit screw type base fittings and pin type (snap-in). Most CFLs either consist of a number of short glass sticks, or two or three small tubular loops. * High-Intensity Discharge Lamps- High Pressure Sodium (HPS), Metal Halide, Mercury Vapor and Self-Ballasted Mercury Lamps are all high intensity discharge lamps (HID). With the exception of self-ballasted lamps, auxiliary equipment such as ballasts and starters must be provided for proper starting and operation of each type bulb. Compared to fluorescent and incandescent lamps, HID lamps produce a large quantity of light from a relatively small bulb. * Low-Pressure Sodium Lamps- Low-pressure sodium lamps have the highest efficacy of all commercially available lighting sources. Even though they emit a yellow light, a low-pressure sodium lamp shouldn't be confused with a standard high-pressure sodium lamp. Low-pressure sodium lamps operate much like a fluorescent lamp and require ballast. * LED (Light Emitting Diodes)- Light Emitting Diodes (LED) are bulbs without a filament, that are low in power consumption and have a long life span. LEDs are just starting to rival conventional lighting, but unfortunately they just don't have the output (lumen) needed to completely replace incandescent, and other type, bulbs just yet. Never the less, technology is advancing everyday, and it will not be long until the LED bulb will be the bulb of choice for most applications in the home and work place.
Different Lights Can Save Energy and Cut Costs
Different lighting can attack someone’s budget, both positively and negatively; positive is what we aim for. There are a variety of bulbs, or lamps, that save people money. There are LED’s, CFL’s and many more. Budgeting a person’s lighting in their home can save individuals money to explore other fun activities on...
