The good news is that technology today is so sophisticated that many of these lighting types are stimulated with motion sensors. Thus, it makes the lamps energy efficient and inexpensive. The sensors allow the lights to be powered on at dusk and off at dawn. Wireless devices are also available wherein the power source can be mounted even without having a nearby electrical outlet or underground wiring.
Many salespeople in marketing LED for some reason may give customers to provide some fuzzy information, resulting in misleading, such as LED life of about 100,000 hours, where the 100,000 hours is the manufacturer expected LED life. As the light source of the light, the brightness of the lamp has a process of gradual decay and darkening (such as fluorescent lamps) , Energy-saving lamps), this process referred to as light failure. In the application-level LED, the light failure of more than 50%, the human eye can clearly feel the brightness of the change, then the product brightness we think is not suitable for lighting. Many manufacturers and engineers in the use of low-cost LED three months to six months or so, often found that the brightness of LED is not as bright as the installation of light, or even almost no, it is because the LED lamp failure did not take into account the reasons. In summary, we have to pay attention to the purchase of LED light decay of its speed, rather than the use of time.
One of the more unique and visually-pleasing lighting techniques in decorative garden lighting is the use of fiber optics. Fiber optics is the science of transmitting light via optical fibers. Optical fibers are extruded cylinders of plastic or glass used to transmit light. All that is required to illuminate the optic fibers is a single light bulb; making fiber optic lighting an affordable garden lighting choice. Another great advantage of fiber optic lighting is that it uses no electrical current; therefore it is safe to place in and around water without danger of electrocution. Therefore, fiber optic lighting can be used to illuminate a garden pond, tree trunks and branches, shrubs, plant containers and even a patio deck.
