Each lamp is attached by contacts to the wire and has a staked end which can be pushed into the ground to keep the lamp anchored and secure. Wire can be buried under two or three inches of soil or mulch. Today, a new line of LED landscape lighting lamps are available. LED's last longer, provide bright, white light and are more energy efficient. Transformers, wire and lamp heads can be purchased separately or in a kit which includes wire, transformer, contacts and lamps. Kits come in a variety of wattages and lamp styles and range in cost from $20.00 to $150.00, depending on the size of the transformer, length of wire and number of lamps.
LEDs produce light by the process of Electroluminescence. This is the phenomenon where by light is emitted from a material when an electrical current is passed through it. An LED chip is made from a material doped with 'impurities' to create a p-n junction between two types of semiconductors and electron holes. Electrons can only flow one way across the junction and as they do they fill electron holes causing their energy level drops and the release of photons (light).
It may be easier to think of colored LEDs (RGB) and white LEDs in terms of another industry: Automotive. RGB LEDs are like the internal combustion engine: Reliable, abundant, easy to use and manufacture, and fairly well developed in terms of the potential for new or breakthrough technologies. There are lots on manufacturers and each has their own set of patents and "tricks of the trade" to help give themselves some marketing leverage over the competition. White LEDs are like the alternative energy industry for transportation: Quite varied, still relatively "new", still needing to be market proven, more expensive, more challenging to manage. There are many manufacturers, each using a different technology or combination of technologies to achieve what they believe is the "the next big thing." Following this analogy, RGB LEDs are mature enough to compete on cost alone and the drop in costs is what fuels new applications for colored LEDs that had not been thought of previously. White LEDs, on the other hand are still developing technically and should not be shopped based on cost alone. The need for quality and longevity is what fuels the further research and development into white LEDs.
