The All-Round Flashlight Expert

NITECORE (SYSMAX) is a member of PLATO, participating in and helping to develop
the ANSI/NEMA FL1 standard of measurement. Product testing data is in accordance
with these internationally recognized scientific standards.

Thermal protection

As the HC90 is very compact, extended operation in turbo mode will cause the body
temperature to continually rise, thus potentially making it too hot for comfortable use.
As a result, Nitecore does not recommend using the HC90 in turbo mode for extended
periods. To prevent overheating, the HC90 has a built-in thermal protection sensor
which prevents overheating by automatically reducing output when a temperature of
55°C is reached. This function ensures user safety and protects the headlamp from
failure / damage.
Precaution:

When the headlamp is hot, do not attempt to cool it by submerging in

liquid as differences in internal and external air pressure may cause water ingress and
irreparable damage.

Changing Batteries

Batteries should be replaced or recharged when output appears to be dim or the
flashlight becomes unresponsive.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating
of silicon-based lubricant.

Warranty Service

All NITECORE® products are warranted for quality. DOA / defective products can be
exchanged for replacement through a local distributor/dealer within the 14 days of
purchase. After 14 days, all defective / malfunctioning NITECORE® products will be
repaired free of charge for a period of 18 months from the date of purchase. After 18
months, a limited warranty applies, covering the cost of labor and maintenance, but
not the cost of accessories or replacement parts. The warranty is nullified in all of the
following situations:
1. The product(s) is/are broken down, reconstructed and/or modified by unauthorized
parties.
2. The product(s) is/are damaged through improper use.
3. The product(s) is/are damaged by leakage of batteries.
For the latest information on NITECORE® products and services, please contact your
national NITECORE® distributor or send an email to [email protected]
The Nitecore official website shall prevail in case of any product data changes.

HC90

General Operation

The HC90 utilizes a sliding switch to access the light’s numerous functions and
brightness levels. With HC90 head facing forward, the order of modes (sliding the
switch from right to left) are as follows: blue mode -> green mode -> red mode ->
standby mode / off -> infinite brightness mode (ultra-low to high) -> turbo mode.
These modes may be cycled through in reverse by sliding the switch from left to right.
When using the HC90 in infinite brightness mode, runtime will increase when lower
levels of output are selected. On its lowest setting, the HC90 will run continuously for
up to 200 hours and on its highest setting continuously for up 2 hours.
NOTE:

A fully charged 18650 lithium-ion battery has a standby time of approximately

6000 hours (off position on the sliding switch). To prevent battery drain entirely (for
example during long periods of inactivity) Nitecore suggests unscrewing the battery
cap approximately half a turn. This will physically cut power to the headlamp and also
help prevent accidental activation.

Charging Function

HC90 is capable of charging a protected 18650 li-ion battery using the included USB
cable. Simply install a protected 18650 li-ion cell, plug one end of the USB cable into
the HC90’s mini USB port and the other end into a universal USB port or adaptor as
shown in the adjacent image.
1.Fully charging a depleted 18650 li-ion battery takes approximately 6 hours.
2.Under normal charging conditions, the red indicator light near the charging port will
blink every 1.5 seconds.
3.If a problem is detected during the charging process, the HC90 will stop charging
and the red indicator will blink rapidly.
4.When charging is complete, the red indicator will illuminate steadily.

Output & Runtime

NOTICE

The above data has been

measured in accordance with the

international flashlight testing

standards ANSI/NEMA FL1 using

one x 3.7V 2600mAh Nitecore

18650 battery and 2 x 3V

1550mAh Nitecore CR123

batteries under laboratory

conditions. The data may vary

slightly during real-world use due

to battery type, individual usage

habits and environmental factors.
*Infinite brightness adjustment

varies from 0.2 to 530 lumens

and is manually adjusted via

sliding a switch. Subsequently,

runtime will vary anywhere from 2

hours to 200 hours depending on

chosen level of output.

Battery Installation

Insert 1 x protected 18650 battery
(recommended) or 2 x CR123A / 2 x
RCR123 batteries with the positive (+)
and negative (-) ends corresponding
with the diagram below.
WARNING
Ensure when turning the HC90 on, the
beam is directed away from the eyes of
people or animals.

Warning:

The HC90’s charging functionality is

designed for 18650 rechargeable li-ion only. Do not
attempt to charge non-rechargeable batteries such
as CR123 or other types of rechargeable cells such
as RCR123 batteries.
