Please read the following notes 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 80%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 60%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 iron 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. Soldering
When soldering, for Lamp without stopper type and must be leave a minimum of 3mm clearance
from the base of the lens to the soldering point.
To avoided the Epoxy climb up on lead frame and was impact to non-soldering problem, dipping
the lens into the solder must be avoided.
Do not apply any external stress to the lead frame during soldering while the LED is at high
temperature.
Recommended soldering conditions:

5. Repairing
RepairshouldnotbedoneaftertheLEDshavebeensoldered.Whenrepairingisunavoidable,a
double-head soldering iron should be used (as below figure). It should be confirmed beforehand
whether the characteristics of the LEDs will or will not be damaged by repairing.
6. Caution in ESD
Static Electricity and surge damages the LED. It is recommended to use a wrist band or
anti-electrostatic glove when handling the LED. All devices equipment and machinery must be
properly grounded.
