• Alkaline (LR6)
• Lithium (L91)
• Rechargeable Nicad or NiMH
Undo velcro closure and remove plastic tube.
Slide the top cover off and slide out the battery chassis
Observe proper battery polarity when installing the batteries.
WARNING
• Never mix fresh and used batteries.
• Never mix different battery brands or chemistry types.
• 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: www.batteryrecycling.com
Improper installation of the batteries will damage the light and
void the warranty.
Lithium batteries hold a charge better in extreme cold weather
and are lighter in weight than Alkaline or rechargeable
batteries. Rechargeable Nicad or NiMH batteries may result
in reduced brightness in some modes due to lower voltage.
NOTE: Some battery types can emit hydrogen gas, which can
create an explosion potential in sealed devices if it is not
vented or removed. The Apex battery pack is equipped with
a platinum catalyst to remove this gas. Upon severe impact,
the catalyst could fracture and enter the battery pack. If you
notice a rattling sound in the battery pack cap or gray
particles in the battery pack, do not use the headlamp. See
the warranty and return policy for more information.
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 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 power meter returns to red, the light will blink
again to alert you.
Circuitry
The Apex 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 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 uses a current-controlled circuit that maintains
constant light output as long as the batteries have sufficient
voltage. Constant burn time is dependant 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 fails to light:
• Check the batteries for proper installation.
• Inspect the cable for damage.
If the Apex 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.
USA– Lifetime, International 10 year Warranty
Princeton Tec reserves the right to change product specifications
without notice.
Return Policy
If your light fails to operate, follow these simple steps:
1) Check batteries. Replace if necessary.

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.
