Notes:
1. Luminous intensity is measured with a light sensor and filter combination that
approximates the CIE eye-response curve.
2. The dominant wavelength (λd) is derived from the CIE chromaticity diagram and
represents the single wavelength which defines the color of the device.

Please read the following notes before using the datasheets:
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 If the package contains a moisture proof bag inside, please don't open the package before
using.
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.
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.

5sec.Max.
Note: Excessive soldering temperature and / or time might result in deformation of the LED lens or catastrophic
failure of the LED.
5. Repairing
Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a
double-head soldering iron should be used . 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.
