Congratulations for purchasing the finest flashlight available. The Ra
Every Day Carry (EDC) and Ra Clicky Tactical flashlights are
best-of-class flashlights providing regulated output at the desired
brightness for extended periods. A single button easily selects the
desired light output. You can customize your flashlight for added
utility. Lithium-ion rechargeable batteries are fully supported and
recommended for lower operating cost. And your flashlight is built
tough to provide a lifetime of dependable service.
Introduction
You can maximize battery life by selecting the optimum amount of light
for your task. Too much light wastes battery life while too little light
makes it difficult to see. The 4 brightness settings were selected for
maximum utility. You may customize them if desired.
Burst output takes advantage of how your eyes work and the practical
need for very bright light to provide maximum performance while
preserving long battery life.
Your flashlight may be customized to perform special tasks more
efficiently. These customization features allow you to build a
specialized flashlight optimized for the tasks you perform on a regular
basis – and even tasks you rarely perform.
Your eyes respond to light in a logarithmic manner. This means that if
you reduce the amount of light by half, your eyes perceive the change
as a small decrease in brightness. The internal brightness levels on
your flashlight are visually spaced so you will see a very small change
in brightness between the levels. Every decrease of two brightness
levels doubles the battery life while appearing to be a small change to
your eyes.

1. Basic Operation
Quickly press and release the rubber button on the tail of your
flashlight to turn on your flashlight. Your flashlight turns on to the High
brightness setting.
Press and hold the button while your flashlight is on to activate the
Strobe setting. Release the button to return to the previous brightness
setting.
Quickly press and release the button while your flashlight is on to turn
off your flashlight.
2. Advanced Operation
We use the term “click” to indicate a quick press and release of the
button. Think of it like a mouse click on your computer. The button
must be released in less than 1/3 of a second to be recognized as a
click. The term double-click means two clicks in rapid succession and
triple-click means three clicks in rapid succession.
We use the term “press-hold-release” to indicate that the button
should be held down for an extended period – longer than 1/3 of a
second – to allow your flashlight to tell the difference between a click
and a press-hold-release. We use the term “press and hold” to
indicate you should continue to hold the button down until you are told

3
to release it. A click, press-hold-release or a click, press and hold are
a click followed by the press in rapid succession. There is no pause
or delay between the click and the press. The same applies to
double-click, press-hold-release and triple-click, press-hold-release.
You tell your flashlight what to do through a sequence of clicks and/or
a press-hold-release or a press and hold. These sequences, known
as commands are simple and easy to learn. It will take a few minutes
of practice to become proficient with them.
From Off: these commands are available when your flashlight is
turned off:
•Click – turns on your flashlight to the High brightness setting.
•Press and hold – turns on your flashlight to the High brightness
setting for as long as you hold down the button and then turns your
light off again when you release the button.
•Click, press and hold – turns on your flashlight to the Strobe setting
for as long as you hold down the button and then turns your light
off again when you release the button.
From On: these commands are available when your flashlight is
turned on:
•Click – turns off your flashlight.
•Double-click – toggles between the High and Medium brightness
settings or returns you to the last High or Medium brightness
setting used.
•Triple-click – goes to the Low brightness setting.
•Click, press-hold-release – goes to the Strobe setting.
•Press and hold – goes to the Strobe setting for as long as you hold
down the button and then returns to the previous brightness setting
when the button is released.
Please refer to Customizing Your Flashlight, below, for detailed
instructions on customizing your flashlight.
Note: your flashlight will turn on burst output whenever you select the
High brightness setting. After 10 seconds of burst output, the output is

4
reduced one brightness level to the one-hour output level. One level
is a very small change in brightness to your eyes but has a dramatic
affect on runtime.
3. Low Battery Indication
Your light will momentarily turn off and then back on one level below
the previous level when the battery in your flashlight is unable to
supply enough power to run the current brightness level. This process
is repeated when needed as the battery is used up. After this process
starts, your flashlight will double-blink once a minute to remind you
that the battery needs to be changed. Selecting a brightness level
below the current brightness level will extend the dying battery and
turn off the change battery reminder.
Your flashlight restricts the output to the highest brightness level the
battery can maintain. However, if you turn your flashlight off and back
on again to a higher level, it will slowly step up through the brightness
levels testing the battery again.
Your flashlight will slowly blink once a second on the lowest brightness
level when the battery is no longer capable of powering any of the
steady brightness levels.
Warning: continued use of a rechargeable battery after your flashlight
begins blinking once a second on the lowest brightness level can
result in sudden darkness because your flashlight will eventually turn
itself off to protect the rechargeable battery.
4. Installing a New Battery
Unscrew the battery compartment from the head and remove the old
battery from the battery compartment. Insert the new battery into the
battery compartment with the positive terminal out. Align the head
and battery compartment, press them together to overcome the spring
pressure and screw the battery compartment and head back together.
The light comes on dimly for 5 seconds following a battery change to
indicate it is functioning correctly. If you do not see this indication
when changing the battery, remove the battery for 60 seconds and try
again. Removing the battery for 60 seconds forces your flashlight to
“reset”.

5
Your flashlight is designed to work with either primary lithium batteries
or rechargeable lithium-ion batteries. In general, primary batteries
provide longer runtimes. However, Li-ion batteries are less expensive
in the long run and allow you to always leave home with a full battery.
Caution: do not try unscrewing or removing the switch cap. Doing so
may damage your flashlight.
5. Cleaning and Maintenance
Periodically clean the open end of the battery compartment, the
threads and O-ring with a clean lint-free cloth lightly moistened with
isopropyl alcohol. Apply a coat of non-conductive silicon or petroleum
grease to these surfaces.
Replace the battery compartment O-ring if it becomes worn or
damaged. O-ring: 1.5mm x 20.5mm, 70 durometer Nitrile (Buna-N).
The recessed electrical contacts and interior threads can be cleaned
using a lint-free swab lightly moistened with isopropyl alcohol.
Recessed contacts and threads should be cleaned in a counter-
clockwise direction to prevent snagging the swab. Be sure to remove
any particles or fibers that may be left behind. Apply a coat of non-
conductive silicon or petroleum grease to the interior threads.
The exterior can be cleaned with a mild soap and water. Rinse well
and dry with a lint-free cotton cloth.
6. Additional Notes, Cautions and Warnings
Note: your flashlight will reduce output power by single brightness
levels if needed to prevent it from becoming excessively hot due to
high output power.
Note: your flashlight protects rechargeable batteries from over-
discharge under most conditions. However, we still recommend
rechargeable batteries with built-in over-discharge protection for an
added level of safety.
Caution: some individuals may be sensitive to the affects of flashing
lights. Be ready to render assistance if an individual should have a
seizure induced by your flashing light.

6
Warning: your flashlight is very bright on the higher brightness levels.
You should avoid looking directly into the reflector as the light can be
intense enough to injure your eyes.
Warning: a sudden total failure is unlikely but is still possible. We
recommend you always carry a second light during critical situations
(e.g., caving). We also recommend you carry enough spare batteries
to cover your lighting requirements plus a reasonable safety margin. It
is not necessary to start each trip with a new battery in your flashlight
as long as you have spare batteries along.
Warning: only install fully charged rechargeable batteries. Using a
partially charged battery may result in the battery not being properly
recognized as a rechargeable battery. This can lead to the
rechargeable battery being over-discharged and damaged.
Warning: do not recharge a rechargeable battery if you think it has
been over-discharged or otherwise damaged. Dispose of the
damaged battery immediately. An over-discharged or otherwise
damaged battery can vent or explode when the battery is recharged or
when the battery is subsequently used.
Warning: water – especially salt water – in the battery compartment
will cause electrolysis, giving off hydrogen and oxygen – an explosive
gas mixture. Electrolysis will also cause corrosion. If water gets
inside of the battery compartment, immediately open the battery
compartment, rinse the battery compartment and battery with fresh
water and allow your flashlight and the battery to completely dry.
7. Customizing Your Flashlight
Your flashlight may be customized so you can perform special tasks
more efficiently. You can customize each brightness setting through
the Brightness Menu and you can customize many special features
through the Option Menu. Together these features allow you to build
a specialized flashlight optimized for the tasks you perform on a
regular basis – and even tasks you rarely perform.
8. Factory Reset
Please feel free to experiment. You can always return to the original
factory settings by following these steps:

7
•Reset your flashlight - i.e., remove the battery for 60 seconds and
reinstall. Alternatively, you can turn on your flashlight, remove the
battery compartment (your flashlight will go out) and then reinstall
the battery compartment without waiting. Your flashlight will light
dimly for 5 seconds to indicate the reset.
•Press and hold the button before the dim reset indication turns off.
The light will become brighter for 10 seconds and then turn off.
Release the button when your flashlight turns off.
•Note: your flashlight will display 5 rapid flashes and no settings are
changed if you release the button before your flashlight turns off.
•Note: your flashlight will display 10 very rapid flashes if there is
insufficient power to memorize the original factory settings.
9. Enabling Customization
Customization is disabled by default. Follow these steps to enable
Customization:
•Reset your flashlight - i.e., remove the battery for 60 seconds and
reinstall. Alternatively, you can turn on your flashlight, remove the
battery compartment (your flashlight will go out) and then reinstall
the battery compartment without waiting. Your flashlight will light
dimly for 5 seconds and turn off to indicate the reset has
completed. You have 10 seconds following the reset to begin the
next step. After 10 seconds, your flashlight will ignore attempts to
enable Customization.
•Perform a 20-click, press and hold. You don’t have to count the
clicks because you are allowed to enter more than 20 clicks prior to
the press and hold. After the 20th click your flashlight stops turning
off with every other click.
•Hold the button until your flashlight turns off. Your flashlight will
display a dim-to-bright sequence to indicate it is enabling
Customization and then turn off. Release the button after your
flashlight turns off. Customization is now enabled.
•Note: your flashlight will display 5 rapid flashes and Customization
is not enabled if you release the button before your flashlight turns
off.

8
•Note: your flashlight will display 10 very rapid flashes if there is
insufficient power to memorize the setting.
We recommend you disable Customization after you finish
customizing your flashlight. This allows you to hand your flashlight to
anyone without fear that someone will accidentally modify your
settings. See the Option Menu item #6.
10. Internal Brightness Levels
Your flashlight includes 22 or 23 regular brightness levels, depending
on the maximum output of the model. These brightness levels are
visually spaced so that the difference between any adjacent
brightness levels will appear to be a small even change. This visual
spacing takes advantage of the logarithmic nature of your eyes to see
a huge dynamic range – from very bright summer scenes to dim
moonlit scenes. Your flashlight can produce a range of brightness
levels that spans over 2000:1, depending on the model. Each
brightness level is separated by a ratio of 1.4:1 – enough to provide a
small but noticeable difference between brightness levels.
The amount of power your flashlight consumes is related to the
amount of light it is generating. The more light generated, the more
power consumed. By reducing the light output by a single level at the
higher output settings you can dramatically reduce the power
consumption and dramatically increase the runtimes. And because
your eyes perceive light logarithmically, you will barely notice the
difference between the two brightness levels.
The maximum brightness level – also referred to as the burst level –
trades efficiency and runtime for maximum light output. The burst
level is automatically limited to 10 seconds per invocation. The burst
level drops to the next lower brightness level after 10 seconds of use.
You may return to the burst level as often as you like for another burst
of maximum light.
In addition to the regular brightness levels, there are three light shows:
tactical strobe, emergency strobe and SOS. These three light shows
are treated as if they were additional regular brightness levels.
The following tables show the brightness levels and the corresponding
lumen output. The maximum output of your flashlight will determine
which row to use. The values in the table are calculated and rounded
while values used in the specifications are sometimes truncated. This

9
may result in the numbers in the table being one digit higher than
found in the specifications.
The shaded entries in the table correspond to High, Medium, Low and
Strobe, respectively, for the 23 level models. High and the three light
shows are one level lower for the 22 level models.

The brightness levels are arranged in a circular menu to make
scrolling through all of the brightness levels easier. The maximum
brightness level is followed by tactical strobe, emergency strobe, SOS
and then the minimum brightness level. And vice versa.
11. Customizing the Brightness Settings
Your flashlight comes with 4 preset brightness settings. Don’t be
confused by the names we gave each brightness setting – we chose
the names based on the factory settings. Each setting may be
customized to any brightness level. For instance, you can assign the
emergency strobe to the Low setting and you can assign a very dim
brightness level to the High setting.

10
Follow these steps to customize a brightness setting to one of the
brightness levels:
•Select the brightness setting you want to customize.
•Double-click, press and hold. Your flashlight will pause at the
current brightness level for 1 second and then begin to scroll up
through the brightness levels pausing two seconds at each level.
When your flashlight reaches the maximum brightness level, it will
double blink and pause for 3 seconds. Each light show level is
then displayed for 4 seconds. Upon reaching the minimum
brightness level, your flashlight will again double-blink and pause
for 3 seconds before continuing through the regular brightness
levels.
•Note: the scrolling direction reverses each time you invoke the
double-click, press and hold command. If the scrolling direction is
not the desired direction, release the button and repeat the double-
click, press and hold command to scroll in the opposite direction.
•Release the button when you reach the brightness level you want.
•Turn off your flashlight to save the customized setting.
•Note: switch to a different setting prior to turning off your flashlight
to undo the customization. For example, press-hold-release will
momentarily switch to the Strobe setting and then back to your
selected setting and undo your customization.
•Note: your flashlight will turn off with 10 very rapid flashes if there
is insufficient power to memorize the setting.
12. Customizing Features Using the Option Menu
Your flashlight offers the following features through the Option Menu:
1. Force Setting – indicated by a <long flash>
2. Button Lock – indicated by <three rapid flashes>
3. Automatic Turn Off – indicated by a <bright-to-dim> sequence
4. Locator Flash – indicated by a <dim flash>
5. Momentary – indicated by a <long-short flash> sequence
6. Customization – indicated by a <dim-to-bright> sequence

11
Follow these steps to customize your flashlight using a feature from
the Option Menu:
•Triple-click, press-hold-release. Your flashlight will display the
indication for the first menu item (Force Setting – <long flash>).
•Click to move to the next menu item. Double-click to reverse
direction and move to the previous menu item. The menu is
circular – the last item is followed by the first and the first is
preceded by the last.
•Press and hold the button to select the current menu item. Your
flashlight will display a dim-to-bright sequence to indicate you are
enabling the feature or a bright-to-dim sequence to indicate you
are disabling the feature. Release the button after your flashlight
turns off.
•Note: your flashlight will exit the Option Menu with 5 rapid flashes
and without changing the setting if an error is detected. Possible
errors include entering an unknown command, not entering a
command for 10 seconds or not holding the button down until your
flashlight turns off when selecting a setting.
•Note: your flashlight will exit the Option Menu with 10 very rapid
flashes if there is insufficient power to memorize the setting.
Option Menu Item #1
Force Setting – <long flash>
The Force Setting feature allows you to select the brightness setting
used when you turn on your flashlight. Disable Force Setting to allow
your flashlight to remember the last setting used and to use that
setting when your flashlight is turned on the next time.
Follow these steps to select one of the four brightness settings to use
when your flashlight is turned on:
•Disable Force Setting.
•Select the desired brightness setting.
•Enable Force Setting.

12
Option Menu Item #2
Button Lock – <three rapid flashes>
The Button Lock feature allows you to lock the button on your
flashlight to prevent it from accidentally turning on. When the Button
Lock feature is enabled and your flashlight is turned off, a triple-click
will toggle the button lock – i.e., unlocking the button if it is locked or
locking the button if it is unlocked.
Your flashlight will turn off when you lock the button and will turn on
when you unlock the button. When the button is locked and you press
the button, your flashlight will rapidly blink 3 times to indicate the
button is locked and then turn off.
Option Menu Item #3
Automatic Turn Off – <bright-to-dim>
The Automatic Turn Off feature allows your flashlight to turn itself off
after 10 minutes of inactivity. This can be handy if you carry your
flashlight in your pocket and it gets accidentally turned on or if you fall
asleep with your flashlight turned on.
Your flashlight will turn off gradually, dimming one brightness level
each second. When the minimum brightness level has been reached,
your flashlight will blink slowly 10 times and then turn off. You can
click the button at any time during the sequence to return your
flashlight to the original brightness level and to reset the Automatic
Turn Off timer for another 10 minutes.
Option Menu Item #4
Locator Flash – <dim flash>
The Locator Flash feature allows your flashlight to emit a short flash of
dim light every three seconds when turned off. The periodic short
flash makes it easier to find your flashlight in the dark.
Option Menu Item #5
Momentary – <long-short flash>
The Momentary feature allows your flashlight to differentiate between
a click and a press-hold-release when your flashlight is turned off. A
press-hold-release will act in a momentary fashion when Momentary is

13
enabled – i.e., turning off your flashlight when the button is released.
A press-hold-release acts like a click when Momentary is disabled.
Option Menu Item #6
Customization – <dim-to-bright>
The Customization feature allows you to control access to the
Brightness Menu and Option Menu commands. This menu item can
only be used to disable Customization. See Enabling Customization,
above, to enable Customization.
