Precautions for Use
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 After opening the package: The LED's floor life are 168 hours under 30℃ or less and 60% RH or
less. If unused LEDs remain, it should be stored in moisture proof packages.
2.4 If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
time, baking treatment should be performed using the following conditions.
Baking treatment: 60±5℃ for 24 hours.
