Owners Manual
Read this manual, in its entirety, before using your light. Failure
to follow the instructions it gives, or to heed the warnings it
provides, can lead to serious personal injury or death.

Light System Owner’s Manual Page 2
Dive Rite Lighting System Limited Warranty
➤Dive Rite will — at its sole discretion — repair or replace dive light components proved to
be damaged by faulty manufacture or material, at no cost, for a period of up to one year (365
days) from the date of purchase.
➤Canister bodies and the metal portions of light heads are warranted for the life of the product.
➤Batteries are warranted against defects in manufacture or material for 90 days from date of
purchase. This warranty does not cover loss of battery “burn time”—a condition that results
almost exclusively from mis-use or abuse. Users must read and study the rated “burn time”
information appearing in this manual. Failure to do so can easily result in expensive damage not
covered under warranty.
➤Attempting the charge damaged batteries can further result in damage to chargers. This is
not covered under warranty — nor is damage to chargers caused by nonstandard alternating
current voltages or cycle rates. Chargers returned under warranty must be accompanied by the
battery(s) they were being used to charge. If the battery(s) are determined to be the cause of
charger damage, no warranty coverage will be provided.
➤The warranty also specifically excludes bulbs, lenses, fuses, O-rings or other conditions resulting
from misuse, negligence, failure to properly lubricate O-rings, alteration, accident or unauthor-
ized repair.
➤This warranty applies only to the original retail purchaser. It does not cover commercial or
rental use, nor does it extend to units purchased from other than an authorized Dive Rite dealer
or Tekreational Dive Center.
➤To make a claim under this warranty, the owner must have either completed and returned
the warranty registration card at the time of purchase, or registered his/her warranty using
Dive Rite’s website (www.diverite.com). He or she must then return the damaged items to Dive
Rite, along with a copy of the original purchase invoice or receipt. No warranty service will be
performed for other than registered owners.
➤This warranty becomes void if dive light components are damaged by anything other than
normal recreational diving use, of if they have been serviced or repaired by other than
authorized Dive Rite dealers.
➤Repairs made under this warranty will not extend the warranty period.
➤All further claims, especially for damage after diving accidents, are excluded from coverage
under this warranty.
➤Lamartek, Inc., dba Dive Rite, has no obligation to honor any extension of this warranty.
All Dive Rite light systems are pressure tested at the factory prior to delivery. When light systems
are returned to Dive Rite for warranty service, the first thing we do is assemble the light precisely
as outlined in this manual, including proper lubrication and installation of O-rings. We then
pressure test the light, just as we did when new. If the light passes this second pressure test, we
have to assume that any reported flooding must have resulted from failure to properly assemble
and/or maintain the light as outlined in this manual — in which case no warranty coverage is
provided.

Before You Start…
This information has been developed for your safety. Please read and understand this
manual completely before using your Dive Rite light system.
This manual contains important safety and maintenance infor-
mation. Read this manual thoroughly and become familiar with
all of your scuba equipment before diving.
Important information regarding the use or maintenance of your dive light is
designated, throughout this manual, by the Important symbol appearing above. This
manual also uses several signal words to designate hazards with various levels of
seriousness. These are:
Indicates a potentially hazardous situation which, if not
avoided, could result in damage to or loss of equipment, serious
personal injury or death.
Indicates a potentially hazardous situation which, if not
avoided, may result in minor or moderate injury, or equipment
damage. It may also be used to alert against unsafe practices.
Light Systems Overview
Dive Rite light system components enable users to choose from:
➤Three different High-Intensity Discharge (HID) light heads and four different
quartz-halogen light heads.
➤Five different battery canister configurations.
➤Two different switching mechanisms.
➤A variety of accessories and bulbs in several different wattages.

Light System Owner’s Manual Page 5
High-Intensity Discharge (HID) Light Heads
Dive Rite’s HID light heads enable divers to carry with them a compact, self-
contained underwater light system that is capable of providing a level of illumination
previously available only from lights using surface-supplied power. Among their key
features:
➤To the eye, a 10-watt HID bulb’s outputs is comparable to that of a 50-watt
quartz-halogen bulb. How can this be? Due, in part, to a substantial difference in
color temperature, the perceived output and penetrating power of an HID light is
noticeably greater. Also, just as a fluorescent bulb consumes only a fraction of the
wattage that a comparable incandescent bulb does, the HID bulb consumes but a
tiny fraction of the power a comparable quartz-halogen bulb demands.
➤Because it requires just a fraction of the wattage a comparable quartz-halogen bulb
would, HID light system burn times are substantially longer. With a new, single-
section MLS battery pack, the recommended maximum burn time for a Compact
HID light is 300 minutes — roughly four times greater than it would be for a
50-watt quartz-halogen bulb.
➤An HID’s light output has a color temperature of 6,000–6,500 degrees Kelvin.
This is substantially higher (and whiter) than the typical quartz-halogen light’s
color temperature of 3,000 degrees Kelvin. In fact, it is essentially the same color
temperature as the sun. As a result, an HID light is a much better choice for
underwater video — and nearly any other underwater activity.
➤Quartz halogen bulbs normally yellow in color and/or decrease in brightness as
battery voltage drops. In contrast, an HID Light’s system circuitry helps keep
light output constant. In fact, an HID light is capable of drawing battery packs
down past recommended voltage levels, without any noticeable decrease in output.
For this reason, it is important users keep light use well within recommended
“burn” times.
Available Models Dive Rite HID light heads are available in three different models.
➤10-Watt Compact HID The compact HIS light head looks like a slightly thicker
(but significantly shorter) version of our standard MR11, quartz-halogen light
head. The head contains not only the bulb, but the ultra-small ballast assembly
as well (there is no external “ballast box,” as is necessary on the 17- and 18-watt
models). So small and so light is this head that we do not even use a standard
or “Ergo” hand mount with it. Instead, a simple elastic band that slides over two
fingers enables the head to rest comfortably on the back of your hand.
➤18-Watt H1 HID This version uses the same test-tube style lens as the regular H1,
and accepts special versions of the compact H1 reflector or the larger Lumedyne
video reflector (item number 6270HID). The standard hand mount for the H1-

Light System Owner’s Manual Page 6
style HID light head is Dive Rite’s 6126E “Ergo” mount, which attaches directly to
the reflector collar. (A standard hand mount can also be attached to the H1 HID
light head’s ballast box, either by special order, or as an after-market item.)
Figure 1 Compact, H1- and MR11-style HID light heads.
➤17-Watt MR11 HID The front half of this light head is almost indistinguishable
from its quartz-halogen cousin. The hand mount for the MR11 HID light head is
Dive Rite’s 6126 standard hand mount; this attaches directly to the ballast box.
What Make HID Bulbs Different Among the things that distinguish HID bulbs
from incandescent models is that they have no filament. Like a fluorescent bulb, the
HID creates illumination by creating an arc between poles. The result is an extremely
bright and powerful beam.
The HID is designed for underwater use only. Water not only
provides the necessary cooling medium, it acts as a natural
ultraviolet (UV) filter. Still, users should avoid looking directly
at the bulb, even though it is under water.
Expected bulb life is 1,100 hours — provided you don’t drop it. The HID bulb is
somewhat more impact resistant than most quartz-halogen bulbs, in that there is
no filament to break. It is not bulletproof, however. You should not, for example,
repeatedly turn the light on and off.

Light System Owner’s Manual Page 7
Once activated, you should give the bulb at least four minutes
to warm up to operating temperature before turning it off.
Failure to do so will damage the bulb and is not covered under
warranty. Tr eat the bulb with care, always keeping in mind that
it is among the most expensive components in the system and
financially painful to replace.
Ballast Incorporated into each HID light head is a self-contained ballast assembly.
The HID ballast fulfills two important functions. At start-up, the it converts the
battery pack’s normal 12-volt output to the substantially higher voltage (6,000 volts!)
needed to create an arc in the HID bulb.
Following start-up, the ballast continues to function as a converter, providing
the somewhat higher voltage necessary to maintain the arc. In so doing, it maximizes
battery output, resulting in the light’s unusually long burn times.
The HID ballast box contains no user-serviceable parts. Opening
the ballast box voids all warranty coverage.
Quartz-Halogen Light Heads
Although quartz-halogen lights are not as energy efficient as HID lights (and do
not offer the HID lights’ exceptional burn times), they do have the advantage of
costing substantially less. This makes them a good choice when initial purchase price
is a consideration.
Four different quartz-halogen light heads are available for Dive Rite light
systems. These light heads all have a military specification (mil-spec) coating that
enables them to stand up to the rigors of saltwater diving. Here is a description
of each light head.
MR16 The MR16 is among the most versatile of Dive Rite light heads. MR16
bulbs provide a combination of moderately wide flood pattern coverage, with slightly
more intense spot coverage in the center of the beam. Wide-angle coverage bulbs are
available that provide a softer, more even coverage required for video lighting.
The aluminum casing that houses the MR16 bulb is particularly rugged. It
resists damage from crushing (although the MR16 bulb filament can be broken by
the impact that results from accidentally dropping the head on a hard surface). This
casing makes the MR16 head the best choice for operating in environments that are
especially hard on equipment.

Light System Owner’s Manual Page 8
Figure 2 Quartz-Halogen light head options.
MR11 The MR11 is a compact version of the MR16. Although its beam pattern
is not as wide or as even as that of the MR16, the MR11 has the advantage of
being much more streamlined. This makes the MR11 an excellent choice for helmet-
mounted light heads, or light heads that will be used in high-flow situations.
H1 The H1 light head is designed primarily for cave diving. A compact, adjustable,
2.75-inch/70 mm reflector allows the beam pattern to be focused from a moderately
wide flood to a highly penetrating pinpoint spot light that is highly suitable for
exploration. Also available is a special video reflector (item number 6270) that
provides the widest and softest beam possible for underwater cinematography and
video.
H1 “Short” The H1 “Short” light head is an ultra-light, ultra-compact version of the
regular H1 light head, that is less than half as long as its actuator-style brother. It

Light System Owner’s Manual Page 9
comes with its own built-in “ergo” hand mount and is a favorite among some of the
world’s most experienced cave divers. The H1 “Shorty” is available in a toggle-switch
configuration only.
Figure 3: Dive Rite light system battery canisters.
Battery Canisters
Battery canisters house the power supply for each Dive Rite light system. Dive Rite
battery canisters fall into one of two types:
➤MLS Canisters These house the power supplies for Dive Rite’s top-of-the line MLS1
and MLS2 light systems. No other Dive Rite lights offer as wide a choice of light
heads, or provide as many mounting options.
➤PVC Canisters Dive Rite PVC canisters help meet special needs. For example, the
Wreck and Wreck2 lights provide a cost-effective alternative to bulky, hand-held
lights. The Classic Light satisfies the needs of divers seeking a more traditional
exploration light.

Light System Owner’s Manual Page 10
Figure 4 MLS2 (left) and MLS1 battery canisters.
MLS Battery Canisters MLS battery canister and pack combinations include:
➤MLS2 These canisters use a battery pack containing two 12-volt/7-amp batteries,
wired in parallel to provide 12-volts at 14 amperes. In this configuration, they can
power quartz-halogen bulbs ranging from 20 to 100 watts, for from 420 to 60
minutes, depending on bulb size.
➤MLS1 With its compact size and diminutive profile, the MLS1 is well-suited to
applications in which battery size and weight is a consideration. Its single 12-volt/7-
amp battery pack can power Compact, H1- or MR11-style HID light heads,
providing up to 300 minutes of rated “burn” time. A 50-watt bulb is standard
on quartz-halogen MLS1 lights; however, a 35-watt bulb is recommended if users
desire more than an hour of “burn” time.
On MLS2 and MLS1 lights, 50-watt bulbs are standard; however, 35-watt bulbs
are recommended if users desire more “burn” time. MLS lights are also available
with H1- or MR11-style HID light heads, providing up to 180 minutes of rated
“burn” time.
Here is a guide to the MLS canister features shown in the accompanying
illustration.
1. Canister Section MLS canisters are made from a high-strength, injection-molded,
synthetic material. It is extremely durable. Each MLS light is pressure tested at
the factory; canisters are depth rated to 500 feet/150 meters. As you have already

Light System Owner’s Manual Page 11
seen, canister sections can be daisy-chained together, using the same O-ring seal
as is used by the lids (end caps). The design of the canister creates built-in air
spaces between the battery pack and housing. These air spaces displace water and
create lift to help offset the weight of the batteries. Without these air spaces,
the battery canisters would be up to 15.0 pounds/6.8 kg negative under water.
Because of the air spaces, the canisters are much closer to being neutrally buoy-
ant. For example, each MLS canister section, with its battery, is approximately
1.5 pounds/0.7 kg negative in fresh water — substantially less than the 8.0
pounds/3.6 kg it weighs out of water.
Figure 5 MLS canister features.
2. Canister Lid (Female) This lid (end cap) goes on the end of the canister opposite
the power cord. As with all canister sections and lids, it seals with a large Buna-N

Light System Owner’s Manual Page 12
(Nitrile) O-ring. You make this seal simply by tightening the lid one quarter turn,
by hand or with the special MLS Canister Wrench described shortly.
3. Canister Lid (Male) This lid contains the sealing gland, power cord and, possibly,
the toggle switch (more on these items shortly).
4. Belt Slot The canister’s built-in belt slot accommodates standard 2.0-inch/50 mm
webbing. This allows the canister to be mounted, if desired, to weight belts,
harness waist straps, tank cam straps and similar items.
5. Dovetail Ridges The dovetail ridges on either side of the belt slot are where one
can mount the supplied attachment clamps, described below.
6. Sealing Gland and Power Cord This is what connects the battery canister to the
light head. The power cord is made from a special, heavy-duty material, designed
to stand up to the rigors of underwater use. Unlike conventional power cord
material, it is not hollow, making it difficult for any water that might enter a light
head or canister to travel through the power cord to other components. There
are sealing glands at both ends of the power cord. These glands help form a
watertight seal where the cord enters the canister and light head.
7. Toggle Switch The toggle switch option allows lights to be turned on and off at the
canister. You can read more about MLS switching options on page 17.
8. MLS Canister Wrench After just a few dives, divers will likely find that you
can easily tighten or remove their MLS canister lids by hand. However, should
they need a little assistance removing a lid, the canister wrench (which comes
standard with every MLS1 and MLS2) provides the leverage needed to made
the job even easier.
9. Attachment Clamps A wide variety of hardware and methods are available to
attach MLS battery canisters to tanks, BCs, harnesses and other equipment. If
you are not using the built-in belt slot to attach your MLS canister to your other
equipment, you will most likely use a method that employs the MLS attachment
clamps that appear in the accompanying illustration. These clamps can be used
in conjunction with D-rings, quick links, snaps and a variety of other hardware.
They are a standard item on all MLS systems.

Light System Owner’s Manual Page 13
Figure 6 Additional MLS battery canister features
10.Tra vel Cap As discussed later in this manual, it is important you do not transport
your MLS1 or MLS2 with the battery connected. Doing so can result in
accidental activation of the light, which in turn can cause fire or damage to
expensive equipment, due to the high temperatures at which the light’s quartz
halogen bulbs burn.
Additionally, you should not transport an MLS canister with the battery
inside and both canister lid O-rings in place. Doing so could allow a potentially
dangerous build-up of hydrogen gas over time.
It might seem you could avoid these problems simply by transporting MLS
batteries separate from their canisters. Unfortunately, doing so would leave a
battery pack’s connector strips exposed, and subject them to accidental shorting.
The better way to avoid these problems is to use the MLS Travel caps, shown
in the accompanying illustration. These are included with each MLS1 or MLS2.
The MLS Travel Caps consist of plain, gray male and female MLS canister lids.
(These are designed solely for surface use and cannot be taken under water.)
During transit, use the plain male lid (minus O-ring) to keep the battery pack
safely inside the canister body. At the same time, mate the plain female lid
to the male lid with the light cord, thus better protecting its contact points.

Light System Owner’s Manual Page 14
Additionally, divers can use the small container created by joining a male and
female canister lid to store O-rings, silicone lubricant, bulbs and other spare
parts.
PVC Canisters The three available PVC canister models (Wreck, Wreck2 and
Classic) are formed from a single piece of extruded poly-vinyl chloride pipe. This
is the same material used to construct custom-made diver propulsion vehicles for
deep exploration dives. It makes an excellent pressure vessel — one that does not flex
at depth (and thus require battery pack bulkheads to keep the mounting hardware
from coming loose). PVC canisters are rated for depths of up to 400 feet/120 meters.
Among PVC canister features:
➤PVC canister lights share many features in common with the MLS1 and MLS2
canisters. These features include: the use of special, solid-core power cords; and,
the use of special non-corroding sealing glands designed specifically for underwater
use.
Figure 7 Wreck, Wreck2 and Classic lights.
➤PVC canisters seal using conventional quick-release latches (no special tools
required) and thick, highly-compressible O-rings. These make especially easy to
achieve an effective, water-tight seal.

Light System Owner’s Manual Page 15
Here is additional information on each of the three PVC canister models:
➤Wreck Light The Dive Rite Wreck Light is designed to provide a cost-effective
alternative to bulky, hand-held rechargeable lights. It gives divers the power of a
belt-, harness- or tank-mounted battery canister, combined with the freedom of a
light head that, while ultra-compact in size, provides illumination that equals or
exceeds that of nearly all top-of-the-line hand-held dive lights. Wreck lights come
with an mounting loop for 2.0-inch/50mm webbing.
Equipped with a 10-watt Compact HID light head, the Wreck Light canister
can provide up to a maximum of two hours of “burn” time. The standard quartz-
halogen light head for this canister contains a 20-watt MR-11 bulb, providing up to
60 minutes of rated “burn” time from the light’s 12-volt/2.9-amp battery pack (this
is the maximum recommended wattage for this light). Sixty minutes of “burn” time
is also available when using the H1-style or MR11-style HID heads.
➤Wreck2 Light This two-battery version of the Wreck Light is ideally suited for divers
for whom canister length is not as much of a concern as overall canister bulk
(diameter). A special mounting strap facilitates waist, tank or harness mounting.
The Wreck2 Light is available with H1, MR11 or MR16 quartz-halogen light
heads, of with H1- or MR11-style HID light heads. The standard 35-watt quartz-
halogen bulb provides up to 90 minutes of rated “burn” time from the 12-volt/5.8-
amp battery pack; 120 minutes of “burn” time is available with the HID light
heads.
➤Classic Light The Classic Light is designed to meet the needs of divers seeking a
more traditional exploration light. It is available with H1, MR11 or MR16 quartz-
halogen light heads. The Classic Light’s standard 50-watt bulb will provide up
to 150-180 minutes of rated “burn” time from the light’s 12-volt/14-amp battery
pack. The standard mounting loop facilitate attachment to waist straps or other
2.0-inch/50mm webbing.
Batteries
Battery Type All Dive Rite light systems use sealed, lead-acid batteries (also known
as gel cells). In comparison to NiCad batteries, sealed lead-acid batteries are largely
maintenance free. After each dive, you simply connect them to their charger, plug the
charger into a wall socket, and allow them to fully recharge. It does not matter how
much or how little you used a lead-acid battery during a dive. It will not develop a
memory of a particular dive time. In fact, the only way you can seriously harm a gel
cell battery is to do the very thing you must do to maintain a NiCad battery; that is,
fully or nearly fully discharge it (a condition known as deep discharge). If you ever see
your bulb take on a yellowish appearance, turn it off immediately. Failure to do so can
severely damage the battery and charger, and substantially shorten their life.

Light System Owner’s Manual Page 16
Better yet, consult the “burn time” chart appearing on page 45, and keep light
usage well within the times shown for the battery and bulb you are using. Doing so
will greatly extend battery life.
In summary, lead-acid batteries—while slightly heavier than their NiCad
counterparts—are considerably less of a headache to live with. They enable you to
spend your time between dives relaxing, rather than staying up late to do battery
maintenance.
Battery Packs Depending on the unit chosen, a canister will contain one or two
12-volt batteries, assembled into a single battery pack. All Dive Rite battery packs
have user-replaceable fuses so that, in the event of an accidental short or reversal in
polarity, the fuse will blow before battery damage takes place.
Figure 8 MLS1 and MLS2 battery packs.
➤MLS1 and MLS2 battery packs reside in special MLS battery carriers. These
carriers have contact strips along the top, so that simply by sealing them inside
their respective canisters, the batteries are automatically connected and ready to
be switched on.

Light System Owner’s Manual Page 17
Figure 9 Wreck, Wreck2 and Classic Light battery packs.
➤PVC light system battery packs (Wreck Light, Wreck2 and Classic Light) are self-
contained and utilize a standard, two-pole “trailer plug” connection. These are
more resistant to saltwater corrosion than “banana” plugs and, unlike banana plugs,
are readily available from auto-parts and electronics stores, even in remote areas.
Switch Mechanisms
Dive Rite light systems incorporate one of two different switch mechanisms. They
are:
➤A toggle switch…
➤…and an actuator head.
Toggle Switch A toggle switch is a simple on/off switch mounted on the male
battery canister lid. It is ideally suited for on-camera video lights and light heads
that are normally kept in a helmet mount. In these instances, it is generally easier to
activate a toggle switch than it is to remove the light head from its holder to turn it
on. The battery canister and toggle switch, however, must be within easy reach of the
diver for this system to be effective.
Dive Rite uses special, environmentally sealed toggle switches in its lights.
This way, if any hydrogen gas escapes from the battery, the toggle switch will
minimize ignition potential. Outside the canister, a switch guard helps protect
against accidental activation.
Actuator Head To activate a light system with an actuator, you simply twist the light
head clockwise while holding on to its base. This is particularly beneficial when the
battery canister is mounted next to or below a diver’s tank(s)—in which case getting
to a canister-mounted toggle switch would be difficult. An added benefit of actuator
heads is that they enable divers to quickly switch from one type of light head to
another—in the field—without special tools. Many users own two or more actuators,
so that they always have the one best suited to their next dive. Actuator mechanisms
are available on MLS quartz-halogen H1 and MR16 light heads only.

Light System Owner’s Manual Page 18
Figure 10 Toggle and actuator switch light heads.
Light System Packages
Dive Rite light system components are available in convenient packages that include:
➤Battery canister.
➤Light head.
➤Choice of switching mechanism (when available).
➤A 115 or 230-volt AC battery charger.

Light System Accessories
A wide variety of accessories are available for the Dive Rite light systems. They
include:
➤Spare batteries and chargers.
➤Helmets and helmet light holders.
➤Hand mounts.
Additionally, Dive Rite makes a number of accessories that adapt light components
for underwater video applications, such as wide-angle Lumidyne reflectors for H1
light heads, high-color temperature MR16 bulbs, wet-pluggable power cords, and
more.
Spare Batteries and Chargers Dive Rite lighting systems come standard with a
battery pack and 12-volt charger. Many light system users purchase a second battery
pack and charger. This way, they always have a second battery ready to for the next
dive. Item numbers for these components are:
Item Number Description
6119 MLS Battery Pack, MLS1
6118 MLS Battery Pack, MLS2
6309 Battery Pack, Wreck Light
6314 Battery Pack, Wreck2
6317 Battery Pack, Classic
6024 MLS Charger, for MLS
6024 Charger, for Wreck2, Classic
6310 Charger, Wreck Light
Helmets and Helmet Light Holders Dive Rite helmets (item number 2031) are
designed to help protect wearers from head impact when riding diver propulsion
vehicles (DPVs or “scooters”) and diving in overhead environments with minimal
clearance. They are also valuable in situations in which divers need both hands free,
such as when in low visibility or artifact hunting. Quick-release helmet light holders
(item number 6125) enable users to mount light heads and back-up lights of similar
diameter to these helmets.

Light System Owner’s Manual Page 20
Figure 11 Helmet and Helmet Light Holder
The light holder allows divers to snap these light heads and back-up lights in and
out with ease. Light holders come in very handy when scootering, surveying, lobster
hunting or in any other situation that requires hands-free lighting control.
Figure 12 Hand mounts.
Hand Mounts These enable divers to attach a light head to the back of either hand,
without interfering with that hand’s ability to perform other functions.
➤Standard Hand Mount (item number 6126) This is a rectangular handle with a
helmet light holder attached to its top. The hand mount is popular among cave
and wreck explorers.
➤“ Ergo” Hand Mount (item number 6126E) This is a variation on the standard hand
mount that enables users to change the angle of the hand mount, relative to that
of the light holder. Many divers feel this better conforms to the natural shape
of the hand.
The H1 “Short” head comes with an “Ergo” hand mount permanently attached to
the reflector body. This reflector/hand mount combination (item number 6253E) is
available separately and will work with other H1 light heads as well.
Video Bulbs and Reflectors Video lighting options for Dive Rite light systems include
special bulbs for quartz-halogen MR16 light heads, and a special video reflector for
H1-style quart-halogen and HID light heads.
