Solar powered light posts are put on top of a fence that envelopes your yard. This gives light to areas where passers-by go through, providing security and safety. They are fitted to accommodate both vinyl and wooden fence posts in four-by-four and five-by-five sized posts.
The brightness of the LED is measured by the luminous intensity. The luminous intensity refers to the luminous intensity in the direction of the normal (for the cylindrical tube), that is, the luminous flux emitted by the unit solid angle, in candlelight (Candela, cd). As the general luminous intensity of LED is small, so the luminous intensity commonly used in Mendra (mcd) as a unit. In general, the light source will be different directions to different intensity of its luminous flux, in a specific direction of the unit angle generated by the visible light radiation intensity is called light intensity, referred to as axial brightness.
Talking about its virtues is just uncalled for. Outdoor lighting helps us in many ways. It certainly illuminates the garden and pathways as well as gives a magnificent ambience to the evening parties. Well, if you are the one who looks for some tips on outdoor lighting and its selection, there are some for you.
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.
