ELL50L - Electronic Landing Light

Intelligent Synchronization

To see and be seen

The approved ELL50 is complemented by the new ELL50L. The ELL50L differs in a bigger cooling element, so it ispossible to get the maximum output of 30 watts even if the cooling conditions are bad.

The new Thiesen landing light ELL50L, with its 50 mm (approx 2”) diameter and less than 105 gram is much more compact than its forerunner model ELL80, but has a much greater luminous efficiency. The power input of the ELL50L is only 30 watts, with the light output equal to a 90 watt halogen lamp. Again, Thiesen's state of the art moulding techniques guarantees weather resistance and therefore can be mounted virtually anywhere on your aircraft including even the wheel pants!

The peculiarity of our landing light based on light-emitting diodes is the integrated anti-collision light (ACL). In this technique, the LEDs of the landing light can be controlled as an anti-collision light and is therefore integrated into our system of "intelligent synchronization". Thus, the ELL acts both as a normal landing light as well as anti-collision light in flight direction (ie forward) and increases the visibility of the aircraft in flight significantly.

The ELL50L can be easily connected to a cable of minimum 1.5 mm² cross-section and is prewired with a 0.5 mm² highly flexible cord. An instructions manual and the required shrink tubing are included in the package.

Thanks to its advanced construction the ELL50L is water and seawater resistant and, therefore ideally suited for use in seaplanes. It has temperature controls and is corrosion and UV resistant.

Intelligent Synchronization

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