Authority
2KEY FEATURES
2.1 Description of LETG light fixture
The fixture consists of:
•Two unidirectional yellow LED light sources spaced 381 mm (15”) apart. The two light
sources flash alternatively at a rate of 45-50 times per minute.
•Aluminium housing accommodates LED boards and power supply unit.
•U-shaped aluminium support frame with zenith and azimuth angle adjustment marks.
Zenith angle can be adjusted in a 0° to 20° range in 1° increments. Azimuth angle can be
adjusted in a -20° to +20° range in 5° increments.
•Mounting leg with frangible groove and 2”-11 ½ NPT male threading
•L-823 power connector, 2-pin without monitoring or 5-pin with monitoring.
•Use a control and monitoring device capable of detecting a single burnt-out lamp (MCC )
•The fixture will be installed on a high-strength steel base plate with
2”-11 ½ NP M threading
2.2 Input power
Two versions are available with the following characteristics:
•powered by 2.8 A6.6A series circuit (FAA Mode 1)
•voltage driven 120Vac-240Vac (FAA Mode 2)

4INSTALLATION
The fixture is normally installed on level ground, at the edges of the runway, on a 12” FAA L-867
base, that will be used to house the transformer, and a base plate. Please refer to FAA
instructions provided in AC 150/5340-30 and ICAO Annex 14, vol. I.
Figure 3 - In tallation on FAA L-867 ba e plate and ba e plate
Assuming that the L-867 base has been correctly installed, install fixture and base plate (fig.3) as
follows:
•Thread the fixture connector through U-shaped frame, frangible coupling and locking ring;
ensure to screw the locking ring all the way up to the edge of frangible coupling thread.
•Connect fixture connector to the receptacle in the top section of the base plate
•crew the frangible coupling onto the threaded section of the base plate. Apply anti-seize
grease first and do not tighten yet.
•Orient the row of holes in the frangible coupling in the same direction as the light beam
(horizontally) and tighten the locking ring fully onto the base plate.
•Insert the fixture with the U-shaped frame on the frangible coupling and insert the
alignment pin through the holes. Do not tighten the two rear retaining screws of the U-
shaped support frame.
•Orient the fixture (see section 5).
