●Storage
1. Do not open the moisture proof bag before the devices are ready to use.
2. Before the package is opened, LED should be stored at temperatures less than 30℃ and
humidity less than 50%.
3. LED may be stored for 6 months. When the storage time has reached more than 6 months,
LED should be stored in a sealed container filled with Nitrogen gas.
4. After the package is opened, LED should be stored at temperatures less than 30℃ and
humidity less than 30%.
5. LED should be used within 168 hours (7 days) after the package is opened.
6. Before using LED, baking treatment should be implemented based on the following condition:
pre-curing at 60±5℃ for 24 hours.
●E-Power Operating Procedure
1. E-power700 series products should be operated at 700 mA for ideal performance, but not more
than 700mA.
2. E-power 700 series products must be used in conjunction with heat-sinking devices.
Soldering on Al PCB with mid-connection point while keeping the layout
pattern (ï¿  19.9mm,thickness2.5mm) is another way to help heat dissipation. Thermal
Resistance for aluminum board must be less than 0.65 ℃/W.
3. A non-conductive heat-dissipating paste should be applied between E-power and heat-sinking
device.
4. Sufficient thermal management must be applied. Large LED forward current will cause high
junction temperature and reduce LED life.
