Electronic Landing Light (NON-TSO’d)
Ready for Intelligent Syncronisation (IS)
Mounting instruction for electronic landing light (ELL50)
Dear customer,
the electronic landing light (ELL) is a highly innovative product which contributes to saver airspace. A special feature of the LED based Landing
light is the integrated Anti Collision Light (ACL). Thus the ELL50 is a landing light and an ACL in foreward direction of the flight. This increases
the visibleness of the a/c in flight considerably.
The newly developed "Intelligent Synchronization" schedules the Light pulsations so that there are no overlap of the individual lighting
functions. This scheduling of pulsations Reduces required battery and generator current requirements as if only one light was on at any
given moment (see illustration 1).
Now the new LED technology allows an incredibly excellent, white light with only approx. 10% of the input power compared with conventional
lights. The casting in a high-optical plastic makes the ELL50 absolutely insensitive against water, vibrations and other environmental influence.
The efficiency of the output is much higher, than with conventional electric light bulbs. The self-warming of the ELL50 is low and can be
determined as safe. To avoid overheating, the heat balance is controlled electronically.
This electronic landing light for aircraft (NON-TSO’d) is designed to be mounted at a suitable position at the nose unit or inside the wing. Please
adhere to the following instructions for a professional mounting of the ELL50.
The illumination angle complies to the regulations for general aviation.
Important: Due to high wattage (30 Watts), it is mandatory to put a
cooling system in place (see illustration 2, 3).
Warranty is voided if mandatory cooling system is not in place!

Required materials and tools
4 x 1-core cord, according to the length of fuselage (5 - 8 meters),
clear silicone,
soldering iron, tin solder,
shrink hose (is enclosed).
Recommendations
Cable
We recommend a single core, flexible cable with a cross section of at least 1.5 mm and
one cable with a cross section of 0,75mm² (yellow=Syncronisation).
The ELL is already wired with flexible wire for simple connection with the
landing light and the ACL.
Adhesion
We recommend standard silicon in a tube. It is available in do-it-yourself markets. This adhesion is strong and in case of a dismantling you only
need a sharp knife. We strongly advise against using other kinds of adhesion, like polyester or epoxy resin.
Mounting
For the first time we have designed a new cooling system for the ELL50. At our newly developed central cooling the cooling air is passed
through the central of the landing lights directly to the heatsink. Only with this new system it is possible to implement this high performance on
such a small space.
For new installations we suggest to use our new mounting tubus with integrated cooling air channel. This mounting tubus is laminated with
epoxy resin according on demand. We deliver two variable mounting tubes with different air passage, one with cooling air admittance on the
front side or the other through separate entrance (see picture).
The version with front entrance admittance is intended for cowling mounting or wheel pants mounting. The mounting tubus with edgewise
entrance is intended for plane mounting, but can also be used for cowling mounting if it is possible to aspirate the cooling air at the motor cooling
air admittance. The landing light can be fixed with four small drops of silicon on the four mounting rails at the inside of the mounting tubus.
Cooling of the landing light is strongly necessary to ensure a correct function.

Pasting
Apply only as much silicone as required to paste the ELL plane. With your moistened finger, using dish liquid, clean off any laterally dispensable
silicon, a smooth transition can be modeled between the wing and the ELL.
Please make sure that mandatory cooling is not obstructed by excess silicon.
Silicone needs time to cure (vaporization of acetic acid). The best results are achieved at a temperature of 20° Celsius (68° Fahrenheit). Just
follow the handling instructions of the silicone. The final firmness (stability) will be reached after a few days.

Electric power supply / cable connection to the aircraft system (12 Volts)
The best connection is solder with additional shrinking of the soldering joint with a shrink hose (enclosed). Only use solder for electronic
soldering - never use cored solder. It contains acids which cause corrosion!
Important notes
Carefully mount the cables inside the wing and/or the fuselage. Connect the cables professionally to the aircraft system (RED = positive ACL,
BLACK = negative , blue = positive Landing Light, yellow = Synchronisation) and to a 5 Amps fuse protection. Luster terminals are not
suitable to connect cables. There is a good selection of suitable crimp connections in various shops.
If synchronisation is not in use, please connect the yellow cable to +12V (red cable).
The ELL50 is provided with overload protection. In case of over voltage the protector switches off the ELL50. After reset or voltage drop the
ELL50 is again fully functional. The automatic overload protector shall be activated at a voltage above 18 Volts (if the voltage reduces to a value
below 18 Volts, the ELL will again be functioning).
Servicing / maintenance
Should the ELL50 be scratched, use a good polish to refurbish the damages. With slightly deeper scratches use wet sandpaper with very fine
granulation (800-1000) carefully polish again. Do not use aggressive chemicals like gasoline or solvent.
For day to day cleaning use soap water!
Some insect removers and detergents forces embrittlement of epoxy based plastics and laminates. Use only aircraft certified products.
If the aircraft can not hangarized, please cover the lamps to prevent surface aging!
