8. Cautions(1) The LEDs emit very strong UV radiation. Do not look directly at the LEDs. UV radiation canharm your eyes. To prevent inadequate exposure of UV radiation, wear UV protective glasses.
(2) The LEDs are very sensitive to static and surge. Take a full protection against static and surge.
(3) The powered LEDs generate heat. Heat dissipation should be considered in the application
design to avoid the environmental conditions for operation in excess of the absolute maximum
ratings.
(4) The leads should be bent at minimum 1.5mm away from the base of header. The LEDs should besoldered at minimum 3mm away from the base of header.
(5) The LEDs are intended to be used for ordinary electronics equipment. Do not use the LEDs forthe applications that may require a higher reliability and security and that the failure or
malfunction of the LEDs may threat to life.
(6) Do not reverse engineering by disassembling or analysis of the LEDs without our consent. If
there’s any defectives found, please contact our sales division.

9. Warranty(1) The warranty is valid for UV LED lamps only.
(2) Perform an acceptance inspection on arrival of the goods. Return the defectives if any stipulating
the disqualification and quantity.
(3) Embedding the LEDs into the application and the verification of life and other qualities inpractical use shall be executed by user.
(4) Do not use the LEDs for the applications that require the higher reliability and security and that
may endanger life and health by the breakdown and the malfunction. Seller shall not bear any
responsibility or liability with respect to any claims and damages caused by user’s usage of theLEDs without following our intended purpose or any written consent.
(5) Seller shall not bear responsibility for any damages or defects caused by improper operation at
the current in excess of the absolute maximum ratings that are not covered by warranty.
10.

Miscellaneous(1) The leads are gold plated. They may be changed in quality by exposing to the air contains
corrosive gas. Be careful with the storage environment. The LEDs in the sealed bag can be storedfor maximum 6 months. For the storage more than 6 months up to 1 year, the LEDs should be
stored in the suitable environment of the stable temperature and humidity.
(2) The technical information in this specification is not to guarantee the intellectual property rightsof seller’s nor a third party and not to grant the license.
(3) The appearance and specifications are subject to change for improvement without prior notice.
