It is a better choice to choose an ultra-efficient light emitting diodes (LEDs) to add a little safety and peace of mind to hallways, kid's bedrooms, bathrooms and other spaces.
The technolog
y behind laptop computer screens, LEDs are greener than standard incandescent, and even fluorescent, lightbulbs because they generate almost no waste heat. Most of the electricity used is output as light. LEDs remain cool to the touch, so they don't add excess heat into living spaces, which means less cooling is needed. They last for literally hundreds of thousands of hours, meaning they can go years before they need to be changed, thereby cutting down on landfill waste.
In terms of cost, size and brightness, LEDs are getting better all the time, and are seeing many new applications. Even the best LEDs still aren't really bright enough for use in primary indoor or outdoor lighting, but they work great for accent and decorative applications.
In general, LED nightlights are competitively priced with standard nightlights, and many companies sell now. They cost only pennies a year in energy, and result in much lower carbon emissions over traditional lighting. They can be found at most home improvement, value and even drugstores.
