1. Introduction
Congratulations on the purchase of your new Deep-SeaLite®. The Deep-SeaLite® is a deep
ocean light fixture rated to 11,000 meters (36,000 feet), and can accommodate up to 1000W
lamps. The design features a glass envelope with a specular wet reflector. Three different beam
pattern reflectors are available. The reflectors are protected by a metal crash guard with rubber
boot. The DS4 series of connector/lamp sockets from our Multi-SeaLites are used, making it
easy to re-lamp.
This product has been subjected to extensive testing and development and is widely recognized
as a high quality under- and above-water light of superior design. Features that contribute to the
versatility of the Deep-SeaLite® include the following:
1) The socket/connector assembly unscrews from the light body without the use of any tools,
exposing the lamp for easy replacement. Removal of the light from its mount is usually not
required during the relamping process. Also, the glass-metal seal is not disturbed during
relamping, which increases reliability and eliminates the need for frequent pressure testing.
2) Many lamps of different voltages and wattages are available. The socket is designed position
the lamp filament in the optimal location for highly efficient performance.
3) The spring loaded lamp socket provides positive gripping of the lamp to prevent vibration
related contact failures as well as to provide superior lamp alignment.
4) Three different connector types are available; XSG, LPBH3M and BH3M types. The
standard depth rating of the Deep-SeaLite® is 11,000 meters.
5) Standard construction is of rugged 6061 aluminum and 6AL-4V titanium.

Deep-SeaLite® Pre- and Post-Deployment Checklist
Warning:
After each deployment, carefully check to make sure the light has not flooded. It is
possible for the light to partially flood and then reseal itself while underwater. Upon
surfacing, the light can become internally pressurized, which may be potentially
dangerous. Additionally, if the power remains on when the light has partially
flooded, it is possible for electrolytic generation of an explosive mixture of hydrogen
and oxygen gases.
If a light appears flooded upon removal from the water, it
should be treated as potentially dangerous. Point the light away from persons
and valuable equipment and verify whether or not it is internally pressurized.
Make sure that the power is disconnected as soon as a flooded condition is
suspected.
Each Deep-SeaLite® is shipped ready for immediate use. To ensure that the light will perform
reliably, please observe the following maintenance guidelines:
1) Try to rinse the light with fresh water after use in salt water.
2) Always check to make sure that the the rear bulkhead connector assembly is secure before
