Intelligent Synchronization
ERB2 - Our new development with Intelligent Synchronization and FLARM-Interface

The technology carries on - so we developed the new ERB2-H for you. With LEDs of the newest generation we were able to boost the brightness of about 25%. Simultaneously we reduced the power consumption remarkably. This makes an efficiency enhancement of about 50%!

As a matter of course all our LED position lights / ACLs are water and seawater resistant. Since the electronic parts are completely integrated in the ERB2-H, no black box or other items are needed.

Our ERB2-H complies with FAR23 regulations. Therefore experimental constructors have a genuine alternative to Xenon-Flash lights.

The extremely bright, red rotating sequencing light flash has a beacon angle of 360° and is visible at 30° below and above the horizontal plane.

Like all our other ACLs, the ERB2-H is completely sealed in high grade optic plastic. As all electronic components are in the ERB, there is no additional place needed.

For easy connection, the ERB2-H is already provided with a 1,5/0,25 mm˛ four-wire-cable.

A detailed installation instruction and shrinking tubes are included.

WARNING: Cancer and Reproductive Harm -


FLARM-Interface: As worlds first we integrated a FLARM-Interface in an anti collision light for motorized aircraft in order to increase the visibility and therefore the safety in the airspace. The by the Power-FLARM unit provided signals increase the light pulses and therefore rises the attentiveness.

Intelligent Synchronization: The integration of our well proven Intelligent Synchronization allowes a chronological sequence of power consumption for the connected anti collision lights and prevents battery and generator from becoming overloaded.
