CFLs (Compact Fluorescent) only use 20-25% of electricity used by incandescents, making them a popular energy efficient choice for homes and businesses. The fluorescent tubing of the lamps can be bent and folded into a variety of shapes. Double turn, triple turn, quadruple turn and spiral shaped bulbs are a standard form but the advent of bulbs such as the Plumen, the world's first designer energy saving light bulb which derives its name from the feathers of a bird and the unit of light, suggests new shapes will continue to appear. For most lamps electronic ballast is contained within the base of the lamp although separate operating ballast may be needed for different voltage operations.
LEDs are nothing like an incandescent light bulb. They have no glass bulb, there is no filament, and there is very little heat produced. This is because LEDs produce light in a wholly different manner. Rather than heat a filament like an incandescent bulb to produce light, which is by the way extremely inefficient, LEDs produce light through a process called electroluminescence. Rather than go into a long and drawn out technical explanation, it's enough to simply say that electrical power is fed through a small piece of semi-conducting material which then emits light energy. This process is extremely efficient, produces little heat, and is basically solid stated in operation, meaning there are no parts to simply burn up or wear out in a short period of time. At the most basic level, an LED is a diode, just like you'd find in a radio or your computer. They're efficient, compact, and powerful light sources that can operate for several years without fail.
Landscape lamps are attached to special landscape wire by a simple contact that pierces the jacket of the wire. The wire is attached to a transformer that is designed to be installed outside and plugged into an exterior GFCI outlet. The transformer, or power pack as it is also called, reduces the landscape lighting from 120 volts to 12 volts, making the run of lamps and the wire safe for dogs, children and the occasional errant lawnmower or gardener digging with a shovel. There is not shock if for any reason, the landscape wire is exposed, cut or compromised.
