Dive Light System Instruction Manual
Beam Adjustment (for broader view o shootingr photo/video)
The standard spot reflectors have a focused 12-degree beam. For a wider spread you may switch to the wide angel beams by
swapping out the reflector cups. Each of the three internal reflector cups can be used independently, allowing you to use different
combinations for different beam angles. Follow the steps below to switch the reflector cups: 1) Remove the light cover. 2) Remove
the three screws that secures the reflector cups using a Philips screwdriver 3) Swap out the reflectors 4) Put it back together.
When you remove the reflectors on the LED base you will get a full 90
degrees, which could be used for a wide video or focus beam. The
three metal jackscrews will go in between the front of the light and
the LED base to eliminate the overlapping lights that's caused by the
gap between the bulb and the lens. Make sure you use the right
jackscrews and screws for the upgrade and remember to switch
back to the original jackscrews when you want to use the 12 or 60-
degree lens.
Submerging the Light
The dive light system is rated to operate at depths up to 100 meters (328 feet). Provided that you use the properly light, (see Proper
Usage and Storage and O-Ring Care and Maintenance) you will enjoy this product for hundreds of dives.
O-Ring Care
O-Rings are necessary to ensure a tight seal for underwater use. Our divelight housing uses a double O-Ring design for extra
protection. To replace, simply slip one O-Ring all the way to the base of the housing. The primary ring goes on the thread
directly above the base. Below are steps for proper usage and care of your o-rings before and after every dive.
Remove and rinse the o-rings and thoroughly wipe the o-ring grooves clean.
Make sure the material used does not leave any deposits such as hairs, cotton fibers, and dirt, as they may
cause water leakage
Apply a thin coat of silicone grease to both o-rings; applying too much grease to the seal may cause water
leakage. Do not use paper or cloth to apply grease.
Check the threading on the base for any leak-prone deposits as they may come in contact with the o-rings.
Seat the o-rings in place.
Grease the inner base of housing cover where it slides over the primary o-ring.
Tighten lens cover firmly
Maintenance and Storage
Wash and rinse the exterior of the divelight housing with clean fresh water after use. Remove the housing cover and wipe
away any salt, dirt, sand, or other particles from the components. Do not rinse while lens cover is removed, water will
damage the internal components.
Traveling
Our dive light canisters use a piston + pressure seal design. We strongly suggest that you do not completely tighten the
canisters when boarding an aircraft; the change in pressure will seal the canister so tight that you will be unable to loosen it
without special tools.
