2. Surface Mounting (See figure 1)
a. Using the gasket as a template, scribe four drill position marks on the mounting
surface. Drill a 9/32" (7.1mm) diameter hole at each of the outside drill posi-
tion marks for mounting. Drill or punch a 1-3/8" (34.9 mm) diameter hole at
the center drill position mark for conduit entry.
b. Set light on gasket and attach to the mounting surface using the provided 1/4"
screws and washers.
c. Attach suitable 1" NPT hub or connector to conduit entrance in bottom of light.
For Type 4X/IP66 applications, the hub or connector must be suitably rated
(Myers ST-3 or T&B H100-TB hubs are recommended.)
d. Refer to section E for information on making electrical connections.
C. Beam Adjustment
The angle of the sealed beam lamp can be altered if desired. The light is shipped
from the factory with the lamp in the horizontal position. To change the lamp’s angle
proceed as follows:
1. Remove dome assembly by grasping the die-cast ring attached to the dome and
turning it counter-clockwise.
2. See figure 2. The lamp is locked in place with three 10-32 screws. Remove the
locking screw. Loosen the two pivot screws and adjust the lamp to the desired
position. Tighten the two pivot screws to secure the lamp in position.
3. Replace the dome assembly by turning clockwise until it is seated securely against
the gasket.
