Even though the first light emitting diode (LED) was created in Russia in the mid-1920s, the first visible light from an LED was not invented until 1962. In 1996, the development of the white LED led to much wider usage for these bright lights. Many people buy LED landscape lighting because it uses very little energy, is environmentally friendly, has long life and provides pure light.
You can use LED lights in the landscape to create spot lighting, glowing areas or focal points. The LED (light-emitting diode) is a source of light that uses 1/10th the energy of the incandescent mini light bulbs. It lasts more than three times longer and does not heat up. It is more practical in many ways, but has been somewhat expensive to buy. Because the color is more true than LED’s of yesteryear, Today’s LED’s are more popular to use in the landscape. However, as a price comparison, You can expect to pay 3X-4X the amount for LED’s than you will for conventional low voltage lighting.
