Remarks concerning optical radiation safety*
At low forward current (≤100 mA), and continuous operation, this LED may be classified as LED
product Class 1, according to standard IEC 60825-1:A2. Class 1 products are safe to eyes and
skin under reasonably predictable conditions. This implicates a direct observation of the light beam
by means of optical instruments.
When driven with higher continuous forward current, (up to 800 mA), this product should be
classified as LED product Class 1M, according to standard IEC 60825-1:A2. Class 1M products
are safe to eyes and skin under normal conditions, including when users view the light beam
directly. Class 1M products produce either a highly divergent beam or a large diameter beam.
Therefore only a small part of the whole light beam can enter the eye. However, such optical
products can be harmful to the retina if the beam is viewed using magnifying optical instruments.
Therefore, users should not incorporate optics that could concentrate the output into the eyes.
If intended to operate at very high continuous current (>0.8 A), this product has to be (potentially)
classified as Class 3B LED. Class 3B LEDs may have sufficient power to cause an eye injury, both
from the direct beam and from reflections,so these products are therefore considered hazardous to
the eye. However, the extent and severity of any eye injury arising from an exposure to the light
beam of a Class 3B product will depend upon several factors including the radiant power entering
the eye and the duration of the exposure. Nontheless, adequate precautions should be taken to
avoid direct or indirect viewing into the beam.
*Note: Safety classification of an optical component mainly depends on the intended application
and the way the component is being used. Furthermore, all statements made to classification are
based on calculations and are only valid for this LED “as it is”, and at continuous operation. Using
pulsed current or altering the light beam with additional optics may lead to different safety
classifications. Therefore these remarks should be taken as recommendation and guideline only.
Notes
• The mentioned specifications are for reference purpose only and subjected to change without
prior notice.
• All measurements carried out on blank aluminium heat sink, S = 180 cm², passive cooling.
Measurement results and curve characteristics obtained with other heat sinks may differ.
• Do not view directly into the emitting area of the LED during operation!
• This high power LED must be cooled!

Handling precautions
To prevent damage to the LED during soldering and assembly, following precautions have to be
taken into account.

after being soldered.
e) LEDs are static sensitive devices, so
adequate handling precautions have to be
taken, e.g. wearing grounding wrist straps.
