Mechanical Integration
The lights are equipped with 4 combined mounting positions of thread-
ed or through holes. It can be used to fix the lighting to the specified
position. To secure a long live time additional heat transfer measure-
ments at the holding positions are highly recommended.

Safety Notes
Before working with this unit, read the warning and application instruc-
tions carefully and completely before operating the device.
Have the illuminators commissioned only in compliance with the
specified protective measures. It is essential that you comply with the
permissible ambient conditions. The lighting must be switched o before
installation and/or maintenance. The device must not be used when a
failure may cause personal injury.
1. The device is designed for indoor use only.
2. Light – Due to the risk of irritation of or damage to the eyes or
skin it is not recommended to look directly into the light source.
3. Heat –In case of insufficient heat dissipation or when running the
light in flash mode with a too high duty cycle, the surface tempera-
ture may get hot. Do not touch the product during operation or
immediately after it is turned off. Keep off flammable materials at
any time and allow for sufficient heat dissipation.
4. Electricity – The housing is electrically isolated from the ground
of the power supply. Operate only with the permissible current.
Exceeding the permissible current can lead to the destruction of
the device or to a significant shortening of the lifetime of the LEDs
in the device.
5. Usage – Please prevent mechanical stress to the light surface during
operation. This will lead to an inhomogeneous light emission.
6. Cleaning – The light emission surface has to be cleaned with a
standard glass cleaner and a soft cleaning cloth. Do not use other
material for cleaning as it will damage the device.
