EXTENDED RANGE LED
INFRARED ILLUMINATOR

Thank you for purchasing a quality LUNA product. The model LN-EIR is a very popular
accessory to your night vision unit. It provides a much further viewing distance than the
standard built-in IR illuminator.

Please refer to the images below to identify the parts of the illuminator:

GLOSSARY

1 – Beam width adjustment
2 – Horizontal and Vertical beam adjustments
3 – Mounting bracket and wheel
4 – ON/OFF switch
5 – Battery compartment cover

BATTERY INSTALLATION:

To install the battery please unscrew the battery compartment cover (5) by rotating it
counterclockwise. It may be necessary to hold the rubber attachment string with one finger while
unscrewing the battery compartment cover to ease the process. Once the battery compartment is
opened, please insert one 3V Lithium battery, CR123 type as shown on the body of the illuminator
according to (+) and (-) polarity. Replace the battery compartment cover. The IR is now ready for
use.

TURNING THE UNIT ON/OFF:

To turn the illuminator on please rotate the ON/OFF switch (4) clockwise. You will hear a faint
clicking sound indicating the IR is ON. The illuminator has a smooth power adjustment and the
further you rotate the switch clockwise the brighter the beam will become. IMPORTANT: once you
reach the maximum power the rotation will stop. NEVER try to over-rotate and never apply any
force once the ON/OFF switch is at the maximum power level. Trying to force switch to rotate
further at that point may damage it and void any warranty claims. To turn the illuminator off,
rotate the ON/OFF switch counterclockwise until stop. You will hear again a faint clicking sound
indicating the IR is OFF.

FOCUSING THE INFRARED BEAM:

The illuminator features focusing infrared beam. This feature allows the user to utilize the IR
illuminator in both, enclosed spaces and outdoors. With the beam at its widest setting, the Ir is
useful in illuminating more field of view and does not provide blinding effect on its user. When it is

important to extend the effective distance of the IR beam to illuminate the object as far away as
possible, the beam can be narrowed providing more effective illumination at the longest distance.

The width of the IR beam can be adjusted by rotating the focusing ring (1). The IR is shipped with
the beam in its widest position. To narrow the beam width rotate the focusing ring (1) clockwise.
You will notice the front lens will begin to retract and the IR beam width will begin to narrow.

IMPORTANT: as the front lens retracts all the way there will be a moment when it will become
difficult to rotate it further. STOP at this point and NEVER try to forcefully continue rotating the
lens. This may result in focusing lens assembly being completely removed from the barrel, which
could damage it, if it falls down, and it could allow dirt to enter the inside of the illuminator. If
such situation happens, immediately replace the lens back into the barrel and avoid forcefully
rotating it out of the body again.

MOUNTING THE ILLUMINATOR ONTO THE NIGHT VISION UNIT:

Model LN-EIR-1: Your mounting Bracket (3) is in the shape of a sliding plate and your

corresponding night vision unit should have a slot on top of the body either with or without
removable cover. Once the cover is removed, the IR illuminator can slide in the place of the cover
and can be tightened with the wheel located on the mounting bracket (3).

Model LN-EIR-2: Your mounting Bracket (3) is with the bottom screw. Locate a rail or a
mounting plate on the body of the night vision unit with a threaded hole and attach the illuminator
into that hole by tightening the wheel (3).

Model LN-EIR-3: Your illuminator features standard Weaver/Picatinny bracket. You can mount
the unit directly onto any accessory rail on the weapon, as you would a regular tactical flashlight.

To remove the IR illuminator, first loosen the wheel, then either slide the illuminator out of the
night vision unit, or in case of the screw once the wheel is loose the illuminator is removed.

HORIZONTAL & VERTICAL BEAM ADJUSTMENTS:

This illuminator is supplied with a miniature adjustment wrench, located in the inside back pocket
of the carry case, which you can use to adjust the horizontal and/or vertical direction of the
infrared beam. To do so, you should first mount the illuminator onto your specific night vision
model and turn on the unit and this illuminator. You will then see if the illuminator beam is in the
center of the image, or not. If not, then insert the adjustment wrench into horizontal and/or
vertical adjustment holes (2) and gently rotate it while viewing the image through your night vision
device until the beam is aligned to your liking.
