cover from sealing properly. Gently torque the lamp cover while it sits on
the bulb slug assembly; watch to see if either of the two sealing O-rings
break contact with the test tube.
If the O-rings break contact with the cover, the lamp cover or O-rings must
be replaced. There are occasionally slight variations in the size of lamp
covers (test tubes). Halcyon manages this problem by using components
that fall within exact specifications. Be cautious about purchasing nonstan

dard lamp covers from other manufacturers or suppliers.

Troubleshooting E/O Underwater Pluggable Connectors
Wetmates E/O cords are an available option that adds flexibility and
modularity to any Halcyon lighting system and are a standard feature of
Apollo video lights.
E/O cords offer great advantages in flexibility; however, they require
some minor attention to ensure reliable service. Over time the rubberized
connectors may loosen and weaken the connection. The problem is easily
solved by placing the connector on a hard surface and firmly tapping it with
a rubber mallet. This action will tighten the connector and prevent a sloppy
connection. Another problem that might occur is a slight oxidation on the
connector tip after several dives in salt water. A light sanding with extra fine
sand paper will remove any oxidation and ensure a good connection.
When used with a halogen bulb, an improper E/O connection will cause
the light to flicker. With an HID lamp, an improper connection will interrupt
current, resulting in a loss of light. The effect is the same as if you had
turned the light off with the switch: the ballast must reset itself and the
bulb cool before restriking. If your light should go off because of a loose E/O
connection, re-seat the connection, turn the switch to the off position, and
wait ten to twenty seconds before restriking the lamp.
Disconnecting the E/O cords by pulling at an angle instead of straight out can
also damage the connectors. Bent connectors cannot be reliably repaired.
Use of E/O cords in salt water requires extra consideration for maintenance.
Make sure to rinse and dry E/O connectors after each salt water dive,
as the connections will corrode and degrade performance over time.
Most professional photographers and explorers recommend scheduled
maintenance replacement after every two years if the connectors are
constantly exposed to salt water.
