Section 4 - L-861 Installation Instructions
1. Class 2 - Base Mount
Figure 1 represents an L-861 light fixture installed in the ground. The L-861 is intended for
airfield 6.6A series circuits which use an 30/45W L-830 isolation transformer to connect the
light fixture.
Figure 1 – Installation Diagram
To install the L-861 fixture in the ground with a base plate, use the following procedure:
1. Install an L-867 Base Can in the desired location.

2. Level the Base Can to ensure it is parallel with the grade surface.
3. Fill the area around the Base Can with about 4” of concrete while maintaining the level of
the mounting surface.
4. Connect the 30/45 watts isolation transformer per Figure 2.
5. Wrap the connector mating parts with a layer of rubber tape.
6. Connect the L-861 Base Plate to the Base Can with stainless steel bolts. Use Loctite on each
bolt and tighten to the appropriate torque rating.

2. Class 1 – Direct-Mount (Stake)
L895
Mounting Stake galvanized to ASTM-A123/A123M-02
Shipped with:
1 x 2 hole cable clamp and
2 x #10-24 x 1 ¾” SS machine screws
1. Thread the coupling of the light into the mounting stake and run fixture power cables to
each light, one black wire, one white wire, and one green wire (grounding) to each can.
2. Follow the wiring instructions on the next page.
3. Install the stake in a 6-inch (15 cm) diameter hole at a depth of 30 inches (76 cm). Do not
install stake by driving.
4. Make electrical connections and backfill around the stake with thoroughly compacted earth
passing a 1 inch (2.54 cm) sieve.
5. Where required due to unstable soil conditions, backfill with concrete. Install the top of the
stake even with, or not more than ½-inch (1.3 cm), above the finished grade and maintain
within 1 degree of the vertical.
6. In areas where frost may cause heaving, anchor the stake with concrete and use a permeable
backfill material such as sand around the buried electrical components and then cover the
top surface with an impervious material to reduce moisture penetration.

Section 5 - Maintenance
This section is devoted to helping customers maintain their L-861 elevated lights in the best
condition possible. It is recommended to create and follow a periodic maintenance schedule
tailored for your facility.
Some of the typical problems which may occur with an L-861 and their course of action are:
 Reduced light intensity or burned-out lamp: Remove power and replace lamp.
Measure series circuit current to ensure it is within FAA limits. Clean lens to allow
maximum light output.
 At least once a year it is recommended to check the alignment of the fixture to ensure
it is level with other fixtures.
 The fixture is outfitted with a frangible coupling that is designed to fail upon collision.
In the event that this occurs, a new coupling needs to be ordered and installed.
o Remove the set screw and discard the broken coupling.
o Install new coupling onto the riser and secure by tightening the set screw.
To replace the lamp, ensure power is disconnected. Loosen the clamp band securing the lens to
the housing. Remove the failed lamp and replace it with a new one lamp mentioned in the section 2
parts list. Re-install the lens and tighten the clamp band around the lens.
