Through the ages man has been fascinated by fire since its discovery. Man attempted to harness the power of flame to provide both heat and light. As knowledge about fire evolved, fire became portable. Used to light the interior of caves and dark natural passageways in dense woods, portable fire was both dangerous and unpredictable.
While replacing the light bulbs, the budget is an important factor in deciding which lighting option to choose. It is necessary to buy good quality bulbs that last longer rather than buying a dozen or cheaper ones that keep burning out.

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.
