The most important factor deciding the life of LED  light is the heat , as long as any LED lamp can effectively deal with the heat , coupled with quality –driven and LED chip , so the LED light has good quality , long life span. Take the LED tube light for example, the main components are : LED light source, aluminum plate, drive power , aluminum, lampshade , plug. The LED light source is very important in the packaging process , any inappropriate treatment will result in bad light and light decay. LED is mainly the large or dead lights , the merits of LED chips is a top priority (the quality of LED chip manufactured by the same manufacturers is classified as wafer, raw footage , bulk ，crystal ) , the prices of different chip vary greatly , due to the lighting requirements, so the use of square piece is to encapsulate source. Thus, the manufacturing can easily affect the quality of LED tubes, of course, the price is reduced accordingly . It is not surprising that why many consumers who have been cheated on the market believe that LED products are not reliable. Because consumers are not professional, so when we need to consider manufacturer’s company background, philosophy, capital capacity， service, market influence and so to be judged when purchasing LED tube light. I think it is best to get the address of the manufacturer in advance  and then suddenly visit，which can effectively reduce the risk of cooperation .

The manufacturing costs of many low-end LED tube light manufacturers are saved : ( 1 ) use the second-hand lamp beads, raw footage chip to package light, adopt the straw hat LED light source, the scrap light source to produce LED tube light; ( 2 ) increasing current and pressure . The currents on SMD3528 LED lamp bead increase to 30ma ( This brightness is seems to be reached , in fact, at the expense of the cost of life , the life of  LED tube light is actually less than 1 year) ; ( 3 ) the use of RC power . It is enough to spend 8 yuan buying an RC power , use cheap PCB or cardboard and foil stereotype ( essentially no thermal effects ) to affix the substrate board of  lamp beads, 7 yuan is enough, plus a two-color acrylic tube ( completely regardless of the heat ) , so that an LED tube light costs only about 50 yuan , sold at 80 yuan. There are so staggering profit of 60% .Browsing http://www.ledclan.com for more information about LED tube light.
