Battery Installation
See battery installation diagram
2 CR123
Observe proper battery polarity when installing
the batteries.
• Never mix fresh and used batteries.
• Never mix different battery brands
• Always remove drained batteries immediately.
• Remove batteries during long periods of storage.
Princeton Tec cares about the environment and
recommends recycling batteries. For more
information about battery recycling, please go to:
Improper installation of the batteries will damage the
light and void the warranty.
The battery pack has a waterproof seal. It is important
to keep this seal free from dirt and harsh chemicals in
order to preserve waterproof integrity. Inspect the seal
every time batteries are changed. If dirt is present,
wipe gently with a damp cotton swab and mild soap
until dirt is removed.
WARNING: This product contains Bisphenol A (BpA)
a chemical known to the State of California to cause
birth defects or other reproductive harm.
Battery Power Meter
Multicolored LED
*Capacity percentage is the minimum expected
remaining power needed to operate the Maxbright
LED in high mode at 0° C.
The purpose of the battery power meter is to give you
a general idea of the remaining burn time. Switching
modes can create an abrupt change in battery voltage
which may cause the indicator to change color. Once
the color turns yellow, the burn time remaining
depends on the typical discharge curve for the type of
batteries you are using. After the light has been turned
off, the battery voltage might temporarily increase,
causing the battery power meter to temporarily display
an artificially higher setting.
When the light is off, the battery power meter will
continue to blink for 24 hours to indicate the current
status of the batteries. After 24 hours with no activity,
the battery power meter will turn off to conserve
battery power. When the light is turned on again, it
will resume functioning.
Low Battery Signaling During Use
In addition to displaying red on the battery power
meter, when there are approximately 20 minutes of
run time remaining, the Apex Pro will blink three
times in rapid succession.
You can then decide to stay at your current light level
or switch to a lower light level, which may cause
battery voltage to rise enough that the battery power
meter transitions back to yellow. When the battery

Burn time is the total time that the headlamp produces a minimum of 0.25 lux at 2
meters. 0.25 lux is about the equivalent of a full moon on a clear night. Regulated burn
time is less than overall burn time.

power meter returns to red, the light will blink again to
alert you.
The Apex Pro uses a sophisticated circuit to control
the light. Under normal circumstances, the metal
heatsink will sufficiently cool the electronics and
protect the LEDs from damage. Should the internal
temperature of the light get too hot, a backup
temperature protection circuit will activate and
gradually decrease the light output until the
temperature is within the specified limits.
The Apex Pro will automatically turn off after 12 hours
of inactivity. Any button press during the 12 hour
period will reset the auto-off timer.
Never attempt to disassemble the lamp housing. It is
sealed to protect the components from water and
there are no user-serviceable parts inside.
Disassembly will void your warranty!
To keep the heatsink at peak performance, keep the
heatsink and plastic cover free of obstructions (mud
and dirt). Do not remove the heatsink cover—it is
there to protect you from the high temperature of the
heatsink during operation. If the heatsink cover is
damaged or broken under normal use, do not use the
headlamp. See the warranty and return policy for
more information.
Power Consumption
The Apex Pro uses a current-controlled circuit that
maintains constant light output (Ultrabright LEDs) as
long as the batteries have sufficient voltage. Constant
burn time is dependent on the battery type, LEDs, and
light level selected.
The Ultrabright LEDs provide the maximum level
of wide-angle flood light for task work and the
Maxbright will provide a tightly focused spotlight for
distance illumination.
Trouble Shooting
If the Apex Pro fails to light:
Check the batteries for proper installation.
Inspect the cable for damage.
If the Apex Pro does not seem to change
brightness levels:
• The battery voltage may be too low to switch to
a brighter setting. This condition is normal for a
regulated LED/current-controlled circuit. You are
most likely to experience this issue in the
Maxbright LED mode. Install new batteries and
recheck the modes.
• In extreme heat conditions the internal temperature
of the light may be too hot and the LED
temperature protection circuit may have activated.
Allow the light to cool and try again.
