Welcome:
Thank you and congratulations on the purchase of
your new UW Light Dude light. Just like you, we
are divers. We live for exploration and finding new
caves and wrecks. Our lights were born from
needing brighter, longer burning, and more
dependable lights for exploration. We have
designed a very high quality canister light using the
latest LED technology. From the ground up, all
components used in the design such as LEDs,
optics, electronics, canister material, sealing glands
and battery voltage/size/chemistry, have been
specifically selected to build the best light.
A key feature of the design is that there are no
moving parts to fail, such as on/off toggles or twisty
style O-ring mechanisms (LD-13-DR models have a
toggle switch with switch boot). The on/off and
power level control is conveniently activated by a
non-mechanical Piezo switch milled into the hard
anodized alloy head. Even with the canister lid
open, the battery is sealed in its own watertight
environment (NiMH battery packs are not sealed in
the canister). Turning the light on/off is simply a
matter of pressing the Piezo button for 3 second, so
the canister can be mounted where ever you want
(not just where you can reach it). To switch between
the three different light settings press the Piezo
switch for one second.

*Warning* Batteries have a large amount of stored
energy and are potentially hazardous. Handle
properly and with care.
*Warning* Read carefully and follow the
directions for your particular battery type. Batteries
contain stored energy and can suddenly and
violently release that energy.
*Warning* Use only the battery charger provided.
UW Light Dude lights have different battery
options and not all UW Light Dude chargers are
compatible with your battery.
*Warning* Battery packs may cut power without
warning. Li-Ion packs have built in over discharge
protection.
*Warning* Over discharge of battery packs may
cause damage. If the light dims or begins to flash
the battery pack needs to be charged.
*Warning* Do not look directly or point directly at
another person’s eyes when connecting the power
connectors or turning the light on. The lights are
very bright and can potentially cause damage.
*Warning* When passing other divers ensure that
the light is completely directed away from them.
The beam on UW Light Dudes lights are full all the
way to the outer edge of the beam and can
potentially blind other divers.

Maintaining and Care for your light
UW Light Dude products are designed to be rugged
and require a minimum of care.
Canister Cap O-ring:
1. Before latching the canister cap to the
canister the canister cap O-ring should be
inspected for cuts, nicks, cracks, dust, and
debris.
2. The O-ring should be replaced if cuts, nicks,
or cracks are present.
3. The O-ring does not require grease or oil. If
grease or oil is used to prolong the life of the
O-ring, excess grease or oil should be
removed with a cloth.
4. Excessive grease or oil can cause the seal
between the canister and canister cap to be
impaired.
5. When securing the canister cap to the
canister ensure that wires are completely
inside the canister and that the power
connector (‘s) are lying flat before engaging
the latches.

7
Power Connectors:
1. The bend of the power connectors is
intentional and part of the design. Do not
straighten the connectors as damage or seal
integrity degradation may occur.
2. Each end of the power connectors has an
indentation for connecting and
disconnecting. Place your thumb and finger
on each indention to pull the connectors
apart or push them together.
3. The connectors fit together one way. Ensure
that the connectors are aligned properly.
4. Do not disconnect the power connectors by
pulling on the wires. This may cause
damage.
5. Do not grasp the connector in the middle as
this may make connecting and disconnecting
more difficult and/or cause damage.

8
Charger & Battery Pack:
1. Always follow the directions for the charger
that came with your UW Light Dude model.
2. All chargers should be plugged into their
power source before connecting them to
their power pack.
3. Li-Ion battery packs should only be charged
when needed and removed when the charger
indicates a full charge.
4. Li-Ion battery packs should not be “topped
off” before use. Li-Ion will maintain their
charge for up to or more than a year.
5. NiMH battery packs should be left on their
chargers until they are to be used.
6. NiMH chargers provide a trickle charge
after the battery pack is fully charged to
properly maintain the pack until used.
7. If NiMH packs are removed from their
chargers and not used they should be topped
off before use or every 30 days, whichever
comes first.
8. NiMH chargers have two power settings.
The lower .9 setting should be used
whenever a longer charge time is acceptable.
9. The NiMH chargers high power 1.8 setting
should only be used when a fast charge is
needed.

Transportation & Storage:
1. When transporting to and from the dive site
the power connectors should be
disconnected. If something presses against
the Piezo switch, with power connected, it is
possible the light can be accidentally turned
on and drain the battery.
2. When the power is first connected to the
light head the light will turn on. This is to
ensure the light is working properly. To turn
the light off push and hold the Piezo switch
for more than three seconds.
3. To turn the light on again push and hold the
Piezo switch for more than three seconds.
4. To change light levels push the Piezo switch
for one second.
5. When using the light out of the water the
lowest light setting should be used.
6. If the light is used outside the water and the
internal temperature, of the light head, gets
too high the light will turn the power down
to the lowest setting.
7. After the light has sufficiently cooled the
power can be turned back up to the higher
settings by pushing the Piezo switch for one
second. To move to the next power setting
the switch will need to be pushed again for
one second. Holding the Piezo switch will
turn the light off.
8. The light should be stored in a cool dry
place.

10
9. Storing the light in a vehicle during hot
weather can damage the battery pack.
10. The canister cap should be kept on the
canister when the light is stored, with the
power connectors disconnected, to keep dust
and debris out of the light.
11. When diving in salt water the entire light
should be thoroughly rinsed in fresh water
and dried before removing the canister cap
or storing the light.

11
Attaching the canister and light head:
The canister comes set up with two ways of
being connected to dive gear.
1. The first is the blue one inch webbing that
can be connected to another piece of
webbing such as the waist strap. The lower
end of the webbing has shock cord to make
attaching and removing the canister easier.
If the shock cord is not desired it may be
removed and the lower hose clamp can be
threaded through the bottom loop of the
canister webbing.
2. The second attachment option is the two
loops of shock cord. Double ender bolt
snaps, quick links, or other hardware may be
used to connect the shock cord loops to the
dive gear. The loops work well for back
mounting which is the preferred method of
most side mount divers or to a back plate
which is common with many wreck divers.
3. When back mounting the canister the blue
webbing can be run under the crotch strap to
stabilize the canister and keep it from
moving around.
4. The light head snaps in and out of the
Goodman handle clip. The clip is very
durable and will maintain pressure to secure
the light head for many years. Align the
indentation part of the light head with the
clip arms and push the light head straight
down into the clip.

12
5. Clips may be purchased separately for
mounting the light head to helmets, scooters,
or other accessories.
6. The Goodman handle has a bolt snap
attached so it may be stored on a D-ring
while the head is mounted to another
accessory.
7. The Goodman handle comes with both a
hard and soft handle. Only one handle can
be used on the Goodman handle at a time.
8. The hard Goodman handle has two threaded
holes for storing the screws when the handle
is not being used.
9. The orientation of the soft handle is
important to ensure it remains tight. The
plastic clip has an indentation that should
face down when threaded through the slots
of the Goodman handle.
