Perhaps you remember a time when there was only one kind of light bulb. You would go to the store and they would be there in their own little section. Things today aren’t quite so simple. You have the compact fluorescent, the LED and of course the familiar incandescent. Why are there so many kinds of light bulbs?
Incandescent bulbs work in a similar fashion as the heating elements in your toaster, and like the toaster they generate heat. This is very useful if your goal is making toast, but if all you need to do is provide illumination, then these devices are not the most efficient. It is this inefficiency which led to the development of the compact florescent lights that are slowly taking over the lighting needs in homes all around the world.
Of course, if your intention is to generate heat, then incandescent bulbs may be what you are looking for. Some of these bulbs are made expressly for this purpose, and they are used in many different situations. Food vendors sometimes use them to keep their products warm, and in zoos then can be used to provide heat for some of the animals.
Compact florescent lights are those strange looking bulbs that have been appearing in stores over the last decade. They are like miniaturized versions of the long tubes found in the ceilings of most schools and offices. Though they cost a little more than what most people are used to paying, they can pay for themselves over the course of their lifetimes due to the energy they save.
Shortly after they began showing up in stores, complaints arose about their inferiority to traditional bulbs. Some were unhappy with the delay between turning the light on and actually having it light up, while others disliked the hue that they seemed to cast on the room. But as time passed and the manufacturers began to address these issues the complaints seem to have abated.
At the more expensive end, you can find the LEDs. These little lights have been used in a wide range of devices for many years. For instance, they are responsible for the illumination behind the power button on many electronics, digital displays on alarm clocks and the gauges on the dashboard of your car. They are extremely low energy devices.
According to many, the use of incandescent light bulbs for illumination is going to be ending soon. Citing energy waste, and consequentially environmental damage, many nations have plans in place to phase out their usage. Some countries have already done this.
Lightbulbs Compared to other types of bulbs in the market, this bulb does not heat up very much. If you know exactly what you are looking for, you will save yourself a good amount of time and hassle. Light Bulbs and Their New Replacements: Most people know that the light bulb was invented by Thomas Edison in 1879.
