1) For over-current-proof function, customers are recommended to apply resistors
to prevent sudden change of the current caused by slight shift of the voltage.
2) This device should not be used in any type of fluid such as water, oil, organic
solvent, etc. When washing is required, IPA is recommended to use.
3) When the LEDs illuminate, operating current should be decided after considering
the ambient maximum temperature.
4) LEDs must be stored in a clean environment.
If the LEDs are to be stored for 3 months or more after being shipped from
SAMSUNG, they should be packed by a sealed container with nitrogen gas
injected. (Shelf life of sealed bags: 12 months, temp. 0~40 ℃ , 20~70% RH)
5) After storage bag is open, device subjected to soldering, solder reflow, or other
high temperature processes must be:
a. Mounted within 12 months at an assembly line with a condition of
no more than 30 ℃ /60%RH,
b. Stored at <10% RH
6) Repack unused Products with anti-moisture packing, fold to close any opening
and then store in a dry place.
7) Devices require baking before mounting, if humidity card reading is >60%
at 23±5 ℃ .
8) Devices must be baked for 1day at 65±5 ℃ , if baking is required.
9) The LEDs are sensitive to the static electricity and surge. It is recommended to
use a wrist band or anti-electrostatic glove when handling the LEDs.
If voltage exceeding the absolute maximum rating is applied to LEDs, it may
cause damage or even destruction to LED devices.
Damaged LEDs may show some unusual characteristics such as increase in leak
current, lowered turn-on voltage, or abnormal lighting of LEDs at low current.

10) VOCs (volatile organic compounds) may be occurred by adhesives, flux, hardener or
organic additives which is used in luminaires (fixture) and LED silicone bags are
permeable to it. It may lead a discoloration when LED expose to heat or light.
This phenomenon can give a significant loss of light emitted (output) from the
luminaires (fixtures).
In order to prevent these problems, we recommend you to know the physical
properties for the materials used in luminaires, It requires to select carefully.
