luckylight spec no.: b102 x470 rev no.: v.2 date: nov/26/2005 page: 7 of 7 approved: jojo checked: wu drawn: yao lucky light electronics co., ltd. http://www.luckylight.cn please read the following note s before using the product: 1. over-current-proof customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (burn out will happen). 2. storage 2.1 do not open moisture proof bag before the products are ready to use. 2.2 before opening the package, the leds should be kept at 30 or less and 90%rh or less. 2.3 the leds should be used within a year. 2.4 after opening the package, the leds should be kept at 30 or less and 70%rh or less. 2.5 the leds should be used within 168 hours (7 days) after opening the package. 3. soldering iron each terminal is to go to the tip of soldering iron temperature less than 260 for 5 seconds within once in less than the soldering ir on capacity 25w. leave two seconds and more intervals, and do soldering of each terminal. be careful because the damage of the product is often started at the time of the hand solder. 4. repairing repair should not be done after the leds have been soldered. when repairing is unavoidable, a double-head soldering iron should be used (as below figure). it should be confirmed beforehand whether the characteristics of the le ds will or will not be damaged by repairing.
