Precautions

1. Do not touch the lens with any sharp object.

2. No stress should be applied on the lens.

3. Thermal grease between the light bar and heat sink is recommended to fill air gaps for better thermal conductivity.

4. For securing the LED light bar, M2 screws are recommended. The light bar should not be bent or stressed in any way

which could damage the internal circuit.

5. To prevent damages caused by electrostatic discharge (ESD), it is recommended to wear proper gear such as

wristband or anti-static gloves when handling the product.

6. Constant current source is recommended to power the light bar. When more than one light bar are used, they should

be connected in series if possible.

7. Thermal management should be taken into consideration when using the product. Maximum driving current

should be reduced accordingly at higher ambient temperature to prevent overheating.

8. Soldering recommendations:

z Soldering iron power should not exceed 40W, and should not be in contact with the joint for more than 3.5 secs.

z The maximum soldering temperature should be less than 350°C.

z Do not touch the product immediately after soldering.

z Not reflow compatible.
