If you are looking to bring new life to your home living room, bathroom, kitchen and other areas, consider LED lights rather than halogen bulbs traditional lamps and other home. They also are a great way to "Go Green" and do their part for the environment.
More and more people today these days are looking for ways they can go green in their houses, apartments and offices. There are benefits for the environment and for tax deductions at the end year. Many energy-saving techniques can also help save all year on your home energy bill.
Now that the lighting energy efficiency in the home is becoming more common, we also see improvements in lighting design and an increase in the use of LED lighting in the home lighting systems. Most of us should be familiar with the typical incandescent bulb. It's full of gas and a wire stretched across the interior.
When electricity runs through the filament, it heats up and causes of the incandescent lamp. Incandescent bulbs create a lot of energy wasted and wear over time and needs replacement. The alternative to incandescent bulbs is the halogen light, but it has its problems too. These bulbs are also not very heat efficient.
A new alternative exists, the LED (light emitting diode) bulb. This is basically a combination of the other two types of bulbs, but with an efficiency of heat that can not be matched by the former. The science that is based on is also different from the other two bulbs. Led lights are a brighter light, low energy use and more durable bulb.
Another great thing is that LED lights are now available in a variety of shapes and sizes to suit the lighting you already have in your home. This makes it easier than ever to update your home with new energy efficient lighting, LED.

Does anyone know the answers to these math questions?
A 13-watt compact fluorescent light bulb produces about the same amount of light as a current 60-watt incandescent bulb. Every second it's on, the incandescent light bulb uses 60 joules (J) of electrical power, while compact fluorescent bulb that uses only 13 joules. A) Calculate how much energy the 60 watt incandescent bulb uses in one hour. B) Calculate the amount of energy 13-watt fluorescent bulb uses in one hour. C) Write an equation for the energy used by each bulb. d) How much energy is saved each year if using a 13-watt fluorescent bulb to replace a 60 watt incandescent bulb in a lamp? Let the light is on for approximately 3000 hours in a year. e) How much money would you save each year if the local company charges $ 0.021 per megajoule of electricity? Round your answer to the penny closer. (1 MJ = 1 000 000 J)
You need to show the formulas so that people can help. There should be one that is converted in joules watts.
