INSTALLATION on BRASS SURFACE BOX (BSB)
1. For mounting to concrete, skip to Step 5.
2. When mounting to a wooden surface, use the Mounting Collar to mark locations of the
three mounting screws and hole(s) for the supply wiring.
3. Drill holes for wires as needed and drill pilot holes at the marked screw locations using
a 15/64” drill bit.
4. Secure the Mounting Collar with supplied 3/8” lag screws using a 9/16” socket/wrench.
Proceed to Step 10.
5. Dig a hole at desired location at least 12” diameter x 12” deep and run conduit as
necessary for power supply wires, using the Mounting Collar for positioning. Conduit
should stick up above top of concrete 1/4”. (Figure 1)
6. Fill hole with concrete. Double-check conduit location with Mounting Collar.
7. Once concrete is set, place Mounting Collar over conduit and mark locations for the
three mounting holes.
8. Use a 5/8” masonry bit to drill a minimum 2-1/2” deep hole at each marked location and
tap in the supplied lag shields.
9. Secure the Mounting Collar with supplied 3/8” lag screws using a 9/16” socket wrench.
10. Pull supply wires and verify they are not energized.
11. Feed the wire leads from the xture through the top of the BSB Cover, apply threadlock
to the Base threads, and screw the Cover tightly onto the 1/2” threads in the bottom of
the xture.
12. Use included silicone-lled wire nuts to join xture leads to supply wires as shown in
Figure 1: the black lead connects to hot, the white to neutral, and the green to ground.
Use silicone or electrical tape around wire nuts to ensure proper connection.
13. Slide the xture with the Cover attached straight down over the Mounting Collar.
14. If the xture is equipped with the Half Shield, orient the xture so the light shines in the
desired direction. Alternately tighten the three set screws in the Cover with a 1/8” hex
wrench.
WARNING — Risk of Electric Shock. Verify that power is OFF before installing this xture.
This xture must be installed in accordance with the National Electric Code and/or local
codes. Failure to do so may result in serious personal injury or death. Wiring must be done
by a licensed electri cian.

INSTALLATION on JUNCTION BOX (JB)
1. Dig a hole at desired location at least 12” diameter x 12” deep and run conduit as
necessary for power supply wires. Position the Junction Box (JB) so that the bottom of
its Cover will be above grade after the concrete is poured. (Figure 2)
2. Plug unused holes and ensure all ttings are watertight.
3. Fill hole with concrete, making sure JB is level and that its Cover will be above grade.
4. Once concrete is set, remove Cover using a 5/32” hex wrench and pull the supply wires.
Verify they are not energized.
5. Feed the wire leads from the xture through the top of the JB Cover and gasket, apply
threadlock to the Base threads, and screw the Cover tightly onto the 1/2” threads in the
bottom of the xture.
6. Use included silicone-lled wire nuts to join xture leads to supply wires as shown in
Figure 1: the black lead connects to hot, the white to neutral, and the green to ground.
Use silicone or electrical tape around wire nuts to ensure proper connection.
7. Push the connections into the JB and reattach the Cover/xture assembly.
8. If the xture is equipped with the Half Shield, it can be aimed by loosening the three set
screws at the base of the Shaft (or Lamp Housing if not equipped with a lower Shaft) with
a 3/32” hex wrench. Aim the xture as desired and alternately retighten the set screws.
INSTALLATION on GROUND SPIKE (GS2BC)
1. Dig a hole at desired location roughly 10” diameter x 18” deep and route the supply wires
coming from the power source to the hole, entering it near the bottom. (Figure 3)
2. Remove the Brass Cap from the Ground Spike by removing the screw from the side of
the Cap.
3. Feed the supply wire into the bottom of the Spike and out through the top while placing
the Spike into the hole.
4. Rell the hole while keeping the Spike vertical. Position the Spike so that the bottom of
its Cap will be at grade when the hole is completely lled.
5. Feed the wire leads from the xture
through the top of the Cap, apply
threadlock to the Base threads, and
screw the Cap tightly onto the 1/2”
threads in the bottom of the xture.
6. Use included silicone-lled wire nuts
to join xture leads to supply wires
as shown in Figure 1: the black lead
connects to hot, the white to neutral,
and the green to ground. Use silicone
or electrical tape around wire nuts to
ensure proper connection.
7. Feed the wires and connectors into
the top of the Spike while replacing
the Cap/xture assembly onto the
Spike. Align the hole and fasten
the Cap to the Spike with the screw
removed in Step 2.
8. If the xture is equipped with the Half
Shield, it can be aimed by loosening
the three set screws at the base of
the Lamp Housing with a 3/32” hex
wrench. Aim the xture as desired
and alternately retighten the set
screws.
Mounting on ground spike is only recommended for the 9” version of the MB4. Taller versions
require use of the BSB or JB mounting accessories.

LAMPING – Integrated LED Module
1. Make sure the power to the xture is o󰀨.
2. With the xture still attached, remove the Cap or Cover from the Ground Spike, Junction
Box, or BSB.
3. Disconnect the xture leads from the supply wires.
4. Loosen the three set screws at the bottom of the Lamp Housing with a 3/32” hex wrench
and slide it straight up to remove, exposing the LED Module.
5. If the xture is equipped with a Lower Shaft, loosen the three set screws at its bottom
with a 3/32” hex wrench and slide it up o󰀨 the Base, pulling the wires up through the red
silicone plug inside the Base. (Figure 1)
6. Unscrew the LED Module 4-5 revolutions to remove it.
7. Carefully press the red silicone plug out the bottom of the Base from the top with a
narrow, blunt object and save to be reinserted later.
8. Feed the lead wires from the new LED Module through the Base (or Union and Lower
Shaft, if equipped, then the Base) and screw the Module down until it bottoms out.
9. Replace the Lamp Housing (and Lower Shaft, if equipped) and alternately tighten the
set screws.
10. Feed the leads through the silicone plug. Carefully slide the plug up the wires and
reinsert the plug back into the Base.
11. Follow the nal three Steps in the appropriate “Installation” section of these instructions
to complete the operation.
This xture has a long-life LED Module that should not need replacement for years. However,
if a Module fails or technology improves and a new one is desired, replacements are available
from Beachside Lighting (808-263-5717). Once received:
LAMPING – MR16
1. Make sure the power to the xture is o󰀨.
2. To access the lamp compartment, loosen the three set screws at the bottom of the Lamp
Housing with a 3/32” hex wrench and slide it straight up to remove, exposing the Lamp.
(Figure 1)
3. Using a soft cloth, grasp the lamp and twist it about 1/4 turn counterclockwise. Pull
straight up to remove from socket.
4. Align the pins of the new lamp with the holes in the socket, push the lamp pins straight
down into the socket, and turn clockwise until it stops--about 1/4 turn.
5. Reinstall the Lamp Housing. Apply a grease appropriate for use on silicone o-rings to
the o-rings if necessary.
6. Alternately tighten all three set screws.
