What to do if your light is leaking
This guide will provide instructions for identifying and repairing some
possible leaks in your Halcyon light. If your light continues to leak
after troubleshooting, contact Halcyon for instructions on returning
your light for repair. If any doubt exists about potential damage, please
contact Halcyon for consultation about possible repairs.
If the light has leaked into the lamp cover (test tube), the moisture will
typically corrode the socket and continue to produce condensation. Any
light or light head that has leaked should be opened up and allowed to
dry completely. Please consult the manual section on replacing a bulb for
more information on removing the lamp cover. Be careful not to twist the
lamp cover while removing it and do not touch the bulb with bare hands.
Possible sites of water intrusion:
1. Typically, water leaks into the light as the result of dirty or damaged
O-rings. Check the O-rings in the area of the leak, either the canister or
the lamp cover. Replace the O-ring if it appears damaged. If it is dirty,
clean the O-ring and the O-ring groove with a clean cloth.
2. Canister O-rings should be cleaned prior to every dive by removing the
O-ring and cleaning the seating surface and O-ring thoroughly. Do not
use lubrication on the O-ring; the lubricant will attract sand and dirt,
increasing the risk of leaking.
3. Bulb slug O-rings are highly unlikely to leak unless either the lamp
cover (test tube) or O-rings have been changed from the original fac-
tory installed set. Slight variations in the size of an O-ring can prevent
the lamp 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 nonstandard lamp covers from other manufacturers or
suppliers.
4. Verify that there are no prominent nicks in either the lid or the top lip
of the canister.
